CONTEXT Throughout the ages mankind has made
features in their indoor/outdoor dwellings to
serve a purpose, whether it is a structure to
work from, work on, work with, or even play with.
Mankind has used features to enhance their
indoor/outdoor environments. BRIEF Des
ign a range of possible and alternative
solutions to meet clients needs of an indoor or
outdoor feature to enhance their urban dwelling.
Produce conceptual sketches to communicate your
ideas, and a scaled model to justify and explain
how it meets the brief and the clients needs.
  • INITIAL SPECIFICATIONS
  • The feature is to be manufactured in the schools
    MTech workshop.
  • The feature is to be completed by the 1st of
    November.
  • The appearance/design of the feature that is
    constructed needs to be justified against the
    needs of the client.

Potential Client Issues Miss Keri D A Coffee
Table. Pros I have made a coffee table before
and therefore have past experience to call upon.
Coffee tables are symmetrical and it would
therefore be easy to plan. Cons Coffee tables
use a lot of wood. They are also large and would
be hard to store between classes. It would be
expensive for the client. There isnt many
options for making the table unique. Mrs Mary V
A ladder for her corgi to get into her
car. Pros It is a truly unique idea. Cons I
dont know much about the shapes of cars which
would make the designing difficult. I would
expect a lot of the ladder to be made out of
metal rather than wood, which is outside of my
experience/skill level. Mr Colin W A way to
light up the floor. Pros It gives me the
opportunity to create very imaginative ways of
doing this. It involves electronics which I am
fairly experienced in. It could involve a lot of
materials, from wood, through metal and
acrylic. Cons Because there are so many ways of
doing this I will need to think of extra
imaginative ways of doing this and pick a
particularly interesting way. Ms Josie W A
Bird House. Pros I used to have an aviary and
have also made several bird houses so I could
quite easily make one. They are simple to make so
I could spend more time on making it look good
and designing a unique style. Cons This is a
very simple project and will not test me. It will
be to easy for my liking. Chosen Client Mr
Colin W. Why? Because this project will give me a
challenge. It will allow me to use my imagination
to solve an interesting problem. It allows me to
use electronics which I am very keen upon. I can
have fun with the many options and design
features I could incorporate into this project.
The need is to design a system to light up the
floor in the event of a power cut. The
opportunities are floor, wall, and ceiling
lighting. I will need to research emergency
lighting for this project. Issue My client has
asked me to investigate /design a system to light
up the floor in the event of power cut, that is
entirely reliant upon itself.

Client Survey Q.) Are you interested in having me
as your technology designer, for a indoor/outdoor
feature? A.) Yes Q.) What is the best way to
keep in touch with each other? A.) E-mail. I am
only in school on Tuesday afternoons and the odd
weekend. Q.) What problem do you have for me to
create a solution to? A.) I need you to design a
way of lighting up indoor steps and doorways in
the school in the case of a power outage
(Emergency lighting). I am aware of a sustainable
technology idea for generating power that you
investigated and created last year. I would like
you to design for me a lighting system using this
power generation technology to produce emergency
light for the school in the event of power cuts
or failure in future. Q.) Where is the project
to go? A.) Indoor steps throughout the
school/office environments/Doorways/Walls. Q.)
Can you take a picture of this area? A.) Yes,
picture attached. This is one area in the school
where we could use existing outdoor
lighting. Q.) What time frame do you have in
mind? A.) Over the year of 2009. PROJECT
SPECIFIC QUESTIONS Q.) What style do you want
the project to be? (E.g. time period,
culture) A.) Modern because the school is a
modern school designed purposely for the next
generation of learners. Q.) How much are you
willing to spend/invest in this project? A.) 60
(For materials) Q.) What materials (if any) do
you want incorporated into the design? A.)
Existing stair coverings should be incorporated
into the design. Q.) Do you have any concerns or
thoughts on this project? A.) I would like it to
be a sustainable technology which will support
the school and possible future clients to save
s and resources for the larger community. I am
aware of your self generating idea and would like
you to design and adapt this into a working
solution for the school.

Location
I have two locations. My first location is
stairways. The system should be able to light up
stairways so that if a power cut occurs, users
can see steps and have the ability to climb
up/down them without falling. For the stairway
situation I have 2 options Floor mats/tiles, and
ceiling lighting. I cannot use wall lighting as a
lot of the stairways in the school (Including the
one pictured) do not have walls, only handrails,
which are not suitable to affix lighting and
wiring to.
My second location is doorways. The system should
be able to light up doorways in the event of a
power outage so that users can easily find
doorways if necessary. In both cases the system
should be fit for purpose in the location (i.e.
look good, function well, unobtrusive). For this
location I have 3 options Floor mats/tiles, wall
mounted, and ceiling mounted. For the location
pictured, wall mounted is possible, but
difficult. This is because there is a door on one
side of it, and the other side is under a sink,
hardly a good place to keep electrical equipment,
when the sink might leak. The ceiling and floor
options are slightly more suitable alternatives,
however the height of the floor tiles would need
to be considered carefully.

This doesnt create to much light but is a
feature. It looks stylish and can create an
atmosphere (E.g. party).
This creates light for the client and is a
feature because it is an unusual light in the
sense that it is blue.
This is functional in the sense that the user can
sit on it. It is also a feature because of its
very unusual shape.
This is functional in two ways but not really a
feature. This can be used as a table or as two
chairs. It does not however, look that great. In
the right environment it could look good (E.g. A
high class office).
This is functional and a feature. It can be used
as a table and its unusual shape is effective in
the right environment.
Context Research Indoor features
This is functional and a feature. It lights up a
space for the user and looks neat in the right
environment (E.g. A child's bedroom, a garden.
10
This fireplace is shown as a centre piece. It is
functional in the sense that it can heat the
client up and possibly cook things. It looks
great as a centre piece and the objects around it
are arranged nicely. The materials used are
durable, strong, and suited to the outdoor
environment. Safety would need to be considered
however.
This fireplace is not functional as it is fake.
It is however, a feature and can still enhance an
area.
These are both functional and stylish. They can
be sat upon and although they are not as original
as the pink chair in the lower left of this page,
they look good and could be used effectively in a
garden.
This is a feature but is also functional. It can
be sat under be the client for enjoyment. It can
also be a centre piece and enhances the
environment.
Context Research Outdoor features
This is both a feature and functional. It can be
sat in and because of its unique style, can be a
centre piece.
This is functional and a feature but I dont
think it is shown in the right environment in
this picture. It can be lain on and would look
great in a beach side bedroom. Location would
need to be considered.
This is functional and a feature. It can hold
your umbrellas and the designer has incorporated
a small garden to create a feature out of a
simple object. This was well done.

  • Context Evaluation
  • The key design elements/factors I will need to
    consider are
  • Function. I will need to consider how and if the
    project will function the way my client wishes it
    to. If it does not, I will need to redesign my
    solution.
  • Client. I will need to consider heavily, my
    clients wants, needs and suggestions/requests.
  • Atmosphere. I will need to consider what
    atmosphere my solution will create or how it will
    modify an existing atmosphere. If need be I may
    have to redesign my solution to create the right
    atmosphere.
  • Colour. Colour is related to finishing's and
    style. It will need to be considered when
    finishing my project but not when constructing
    the inner workings.
  • Shape. Shape will be an important factor to
    consider when designing my solution. It will need
    to fit physically into the place it is designed
    for. It will need to look good as well.
  • Environment. The environment will be the deciding
    factor for many of my questions. For example, if
    it were to go outside, I would need to use
    outdoor materials. With every decision I make,
    environment will need to be considered.

LEDs stuck in the wall, pouring light out over
the floor area. (LED means light emitting diode.
It is a very small, bright light that requires
very little power to run)
LEDs in a circular tile that can be embedded in
the floor or on the wall.
LEDs behind a wall mount, lighting up the wall
in an attractive way and supplying light for the
ground.
Clients comments Aesthetically it would be
attractive and modern. More suitable around main
admin buildings and classrooms. Due to existing
concrete floors, the walls would have to be used.
Different shapes and patterns to suit different
areas.
Clients comments It is easier to situate while
it is in a group such as this. Would have to
consider whether casing is suitable for indoor or
outdoor conditions (vandalism, weather).
Clients comments Good idea, would be useful
around the school during parent evenings and
power outages. Would be difficult situating the
lights (E.g. self contained strip lighting). Low
power consumption is good. This would solve a
lack of night lighting around the school. Good
area coverage.
Clients comments Great fun factor. Could be
expensive if it was sound or motion sensitive.
More interior rather than exterior. To much for a
staircase situation but would be great as a
feature part of the floor.
Floor tiles with LEDs that make the whole tile
light up in bright colours (Dance floor)
Specific Research Lighting
A glass tile that could be embedded into the wall
or floor and LEDs could be fitted inside it.
Tile embedded with many small LEDs.
Clients comments The final design/layout would
be very flexible (Different layouts, shapes,
etc). Durability would need to be considered.
Surface would need to be very hard wearing (i.e.
glass). Lights could be controlled by timers or
programs. This is the sort of concept I was
thinking of. A simple tile with either lighting
on it or wired from it.
Clients comments It would be very professional.
If it is set in timber it is easier to service,
however the timber would need to be hard wearing
(i.e. Decking kwila, jara, laminated bamboo).
Need to consider a water proof surface protection
on top of the timber. Safety would need to be
looked at.
LED embedded in metal casing on the ground (In
wood).
Clients comments Lots of different appearance
situations. Very attractive. Would need some way
to maintain the lights (access into the glass
cubes). Could be done in strips, as a sculpture,
safety lighting. Power connection would need to
be considered carefully. Very durable. Different
colours would be an option (E.g. Red for safety).
LED embedded in a metal casing in the ground.
Clients comments One negative would be that the
wiring would need to embedded in the ground. A
positive is that they would be fairly tamper
proof. Individual lights in individual colours.
Would be good for lighting footpath/staircase.
Small size is unobtrusive. Contrast between
surfaces and materials is good.
13
Clients comments Good appeal. Good protection
for the light. Being recessed protects it from
damage and the weather. Being able to use
different colour lights would be very effective
inside. Because of the design it is quite weather
proof.
Clients comments Hard wearing with a stainless
steal finish. It would need to be situated out of
easy reach because of potential damage to the
neck of the lamp.
Clients comments Maintenance would be fairly
easy. Easy to select durable materials with lots
of colour choices. Could be styled on the school
logo colours.
Clients comments Excellent safety. Visually
appealing. Easy to maintain. Range of colours is
possible.
Specific Research Finishing's
Clients comments Would have to be well fixed,
though easy to repair. Very flexible in colour or
pattern.
Clients comments Strong mood lighting. Creates
an atmosphere. Easy to maintain/service and
control (i.e. dimmers)
Clients comments High appeal. Very simple shape.
Easy to maintain. Multiple choices within
construction materials. Unobtrusive. Could be a
more triangular shape also.
Clients comments Professional finish. Dangerous
because of the gaps under the steps. These could
cause people to trip. Where would the light come
from? Within the stair perhaps? The wood finish
leaves little room for colours to be
incorporated.
14
Lighting Evaluation From my clients comments I
see that I will need to consider the ability to
situate my designs as I will not be able to cut
into solid concrete walls. I will need to
consider area coverage of the lighting in my
designs (I may be able to reduce the number of
LEDs necessary if the area coverage of the LED
is big enough). I will use LEDs as my lights as
they have an extremely low power consumption and
stay relatively cool so would not be a fire
hazard. Also, LEDs have very long lives and it
would be unlikely that they would need to be
replaced before whatever system is used wears
out. The aesthetic qualities should be modern and
different shapes and styles could be used for
different areas, or even within one area as a
feature. A system that could be fixed on an
existing wall, floor or ceiling would be easier
to situate than a system that would need to be
embedded in a wall, floor or ceiling. Strength
will need to be considered to counteract
vandalism and wear tear. I will need to
consider how the lighting will activate
(Automatic, manual, a mix of the two?). Size
should be considered as the design needs to be
unobtrusive. Safety needs to be considered.
Finishing's Evaluation From my clients comments
I see that I will need to consider the following
points Maintenance could be an issue to consider
when adding the finishing's. Durability will need
to be considered to ensure the system is not
broken. Water proofing will need to be
considered. The system is for indoor use, but in
wet weather water will be either blown inside or
brought in on the soles of users shoes. Safety
will need to be considered because the design
should not have the potential to cut, cause
abrasions, or otherwise injure a user. Style
flexibility should be considered to ensure the
design will be suitable for its intended
situations. Construction materials should be
considered in relation to cost, durability,
safety, and aesthetic qualities.
15
Specific Research - Existing project.
The theory behind these designs is that when you
stand on the tile, the tile would compress,
pushing the magnets through the coils, then back
again when the foot is lifted and the tile
decompresses. This would generate electricity, if
only a little bit. The energy would be stored in
capacitor banks. My client believes this could
be incorporated into this project to enable the
lighting to be fully sustainable and un-reliant
upon mains power or backup generators and enhance
the indoor environment in a school or office
situation.
16
Specific Research - Existing project.
Coil-magnet system (Basic principle).
The tile systems could be made into may different
shapes and styles. This makes the tile suitable
for more places.
Bottom (wooden base with coils embedded in holes)
Upside down top (to see how the top and bottom
fit together). The top consists of an upper panel
upon which some sort of squishy material is
glued. Magnets are fitted into holes in the
squishy material, that correspond to the holes in
the bottom.
17
Specific Research - Existing project.
Upside down top with squishy material compressed.
Top. Is it viable to have more magnets and
corresponding coils? How many?
Possible measurements. Would be dependant on
location.
This would not be governed by any electricity
laws as the setup will be under 12volts. Not
enough to give a user a noticeable jolt, let
alone injure or kill a user, or to be a potential
fire hazard if wired incorrectly.
18
Existing project evaluation/comments relating to
use within the clients project. Clients
Comments If put onto existing floors a caution
tape or similar will need to be included to warn
people of the height. The surface will need to be
considered because if it is a high polish finish
it will be quite slippery. You will need to
consider a non-slip surface on all of the ideas.
Non-slip surfaces under the mat will need to be
considered also (Glue? Thumb tac?). If the height
of the magnet remains the same but the diameter
increases (E.g. 4 times) will the energy output
be larger? I.e. Less coils but bigger, vs. little
coils but many. Could use one mat the same size
as the doorway/stair or use multiple mats. Would
need to consider some way of protecting the coils
and inner workings of the mat from dirt, water,
etc. The materials used for the coil mats would
need to be water proof and hard wearing, due to
foot traffic and weather conditions. My
comments I will need to investigate existing
dynamo based products and how they
work. Evaluation This is a good idea to use to
meet my clients needs and wants. He has requested
that I develop this idea further to meet the
requirements of his project. This is because it
has the potential to be entirely self sufficient,
is small and unobtrusive, and can be modified
easily to meet future requirements. I will
investigate the different sized magnets and coils
as my client has suggested. I have tested
(Through the science department) that the
magnet-coil idea will work. My client has stated
in his comments that I will need to weather proof
the project because people will be walking wet
shoes through the buildings on rainy days. I will
need to investigate ways to do this.
19
Key Factors. Why is it a key factor? Implications if not considered. Prioritize Interactions.
Client. My client is a key factor because every decision I make will affect the design my client has requested. If my client is not considered in my planning and designing then I will not finish within the requested time frame and the final design will not be what was requested. High My client affects my resources and my materials because different clients can afford different things. The client affects my developments because after looking at the concepts my client will make suggestions that affect my development designs.
Knowledge. My knowledge is a key factor because it will affect what I can actually design and build. If this is not considered I will design something I cant build, or start designing something I have no knowledge of, and therefore will not work in practice. Med My knowledge affects my concepts and developments. This is because I can use my knowledge within them to create a better product. Model/testing, and functional qualities are both affected by my knowledge as the more I know, the more likely my design will be to work and work well.
Concepts. Concepts are a key factor because the are key to designing a solution to the my clients problem. If concepts are not considered then the final outcome will not be as good as it could have been, and the client isnt given a chance to have a say on the design. Low Concepts affect my developments and my model not only because both will be based upon my conceptual designs, but also because in designing the conceptual designs I will be able to see problems and improvements that can be made, and implement them in my developments and model. Concepts also affect my client because it will give my client an excellent opportunity to give his opinion and point out any problems he may foresee. My stakeholders are affected in the same way. Materials will be affected by my concepts in the sense that I can, and my client can, take my designs and decide what materials will work best, and what materials I can actually obtain.
Developments. Developments are a key factor because they are redesigned concepts of my clients wants/needs. If Developments are not considered, the options I can give my client will be restricted to my concept sketches. Low Developments affect my client, and my stakeholders in a similar way to concepts as they also will allow the client and stakeholders to make suggestions and changes to my design. They also affect the materials I use because I may change materials in my developments to improve upon my conceptual designs.
Aesthetic qualities. Aesthetic qualities are a key factor because looks need to be considered. If this is not considered the end product may be quite hideous and not at all desirable, despite the fact that it may work well. Med Aesthetic Qualities affect both my concepts and my developments because the more I consider Aesthetic qualities, the better the concepts and developments will look. Likewise, materials will affect the looks of the design, however, this can be both negatively and positively because different materials have different aesthetic abilities.
Stakeholders. Stakeholders are a key factor because they are the people interested in my design. If my stakeholders are not considered I will not be able to optimize my design for others to use as well as my client. High Stakeholders affect my developments and knowledge as can be seen by the amount of learning I can receive from listening to suggestions and the difference those suggestions can make in my designs.
20
Functional qualities. Functional qualities are key factors because the product needs to work. If this is not considered the end product may not work and will therefore, be pointless and a failure. The end result MUST work. High Functional Qualities affect materials as the amount of functionality affects what materials are needed. This is because different materials have different malleability, strength, and textures, amongst other things. It affects concepts, and developments also because my designs will need to be changed to take into account the amount of functionality that is needed.
Stakeholders. Stakeholders are a key factor because they are the people interested in my design. If my stakeholders are not considered I will not be able to optimize my design for others to use as well as my client. High Stakeholders affect my developments and knowledge as can be seen by the amount of learning I can receive from listening to suggestions and the difference those suggestions can make in my designs.
Model/ testing. Model/testing is a key factor because the outcome of it will affect the design immensely. If this is not considered I may design something in such a way that it seems to work on paper, but in reality it does not, or is unstable. Med Model/testing affects my both my client and my stakeholders because the success of my model will determine how my client and my stakeholders react to my designs. My model also affects my materials because I can learn from mistakes in my material choices and can then choose materials that have more suitable properties in future.
Style Style is a key factor because the style of each situation is different and the design needs to fit in. If this is not considered the design will not be fit for purpose because it will not look good in its surroundings. Med Style affects my stakeholders because different people like/need different styles. If I choose the wrong style I will lose stakeholders. Style also affects my concepts and developments because the more I think about it, the more my designs will be suitable for the situation. On the other hand, materials chosen will affect the style.
Finish Finish is a key factor because people will see the project. If the project looks bad, my client and stakeholders will not see my design as a solution. If this is not considered, my design has the potential to be an eyesore. If my design is an eyesore, it will not be considered as a valid solution. Med Finish affects what my client and stakeholders think of my design, because the finish is what they will see. In contrast, finish is affected by the materials chosen as different materials require different finishing's.
Harmony Harmony is a key factor because the more my design harmonizes with the surrounding situation, the more likely it is that my client will see it as a valid solution. If Harmony is not considered, the design will be likely to end up clashing horribly with the surrounding situation. Med Harmony affects style and finish because to make the design harmonize with the situation, certain finishing's and styles will need to be used, and others will have to be discarded.
21
This first concept is of a strip of LEDs (Light
Emitting Diodes) set into a bracket over a
doorway. These would effectively light up the
ground below the doorway and would not get in the
way of the door or automatic closing mechanism
attached to the door. Would be fairly easy to
attach over stairways as well. It could be
powered by solar panels or perhaps by the tile
design shown in my research. The wiring would be
a hassle however.
Client Comment I like the idea of this concept ,
looks professional, would the lights extend
further out than the door closing mechanism?
Stakeholder Comment A possible solution, I like
the look of this, yet question the actual amount
of light that hits the floor emitted from the
LEDs.
22
This design is of LEDs set behind acrylic panels
in the front of stairs. These could be powered by
solar panels or by the tile design shown in my
research. If the tile design was used the unit
would be easily contained within the step,
without further wiring. The solar panel would,
however, require wiring. This design would be
difficult to incorporate into doorways but could,
perhaps, be embedded in the wall next to the door.
Client A good looking hard wearing concept for
stairs. Plastic panels would need to be strong
enough for general wear and tear and someone
kicking in the step panel.
Stakeholders A great concept for a stairwell.
Excellent lighting concept. I think this can be a
possible future idea you can develop as an
alternative for prospective clients. This could
also be adapted to suit other sources of power
i.e. solar power, sustainable energy. Your third
concept has the most potential to be adapted for
a range of locations and situations.
23
This is probably my most unobtrusive, yet most
problematic design. Unobtrusive because the
entire circuit, wiring, generator, and light
emitter/s would be contained within one small
tile that could be picked up and moved, or fixed
in place. It could be placed on stairs or on the
floor in doorways, even covering the entire floor
space. Problematic because the tile would add an
extra depth to the floor which might prove a
problem to doors that open inwards, and could be
considered a tripping hazard.
Client Aesthetically this could be quite a
stunning design, the only issue with this is how
to hide the cabling in a discreet way as to not
detract from the lights?
Stakeholder This is it! This incorporates the
whole idea of the system you have created. I
disagree with the client, having a capacitor to
hold the charge and the wiring contained in a
panel you can then offer a range of floor panels
varying in size to suit many locations.
Aesthetically this looks stunning and could be
used in corporate environments, offices etc.
because of the finishing glass/ Perspex plastic.
The visual effect is exactly what people look for
in a light. This will offer wider market place
options on sizes and the areas they can cover at
a cost that suits their budget.
24
Conceptual Evaluation My client and a stakeholder
have commented on my designs and there is a
definite preference. My third design (the tile)
is preferred because of its aesthetic
possibilities and the range of environments it
would be suitable for. When further developing my
design I will need to consider the area that the
lighting will actually cover (the effectiveness
of the lighting), how the wiring will be
organised, the durability and strength of the
design, and (in the case of my third concept) how
much height will be added to the floor. If to
much height is added on the wrong side of the
door, the door will not be able to open. Perhaps
specialised mats could be designed in such a way
that when a door opens, it compresses the mat,
both to allow the door room to open, and also to
add functionality to another un-harnessed energy
source that is everywhere the opening and
closing of doors.

  • Initial Brief
  • My client has asked me to create a way of
    lighting doorways and stairways in the school in
    the event of a power cut. This should be entirely
    reliant upon itself and should incorporate the
    magnet-coil tile idea I suggested in my research.
    I am to design and produce a model of a possible
    solution and once my client has accepted it I am
    to make the full scale project.
  • Client I will need to stay in contact with my
    client throughout the design and construction
    process in order to ensure the end result is
    suitable for my client.
  • Knowledge I will need to use all my relevant
    knowledge to design and construct this project to
    ensure it is done to the best of my abilities. If
    I do not know something, I will need to research
    it and incorporate the research into my design.
  • Concepts I will need to create several concepts
    and get my client to provide feedback in order to
    further develop the design.
  • Developments I will need to refine my
    conceptual ideas and create several development
    drawings for my client to provide feedback on, in
    order to further develop my design.
  • Aesthetic qualities I will need to consider
    aesthetic qualities when developing my solution
    to ensure it meets my clients requirements. It
    should also blend in with, and not encroach upon,
    the environment.
  • Stakeholders I will need to talk to my
    stakeholders during the design process to ensure
    that the project not only meets my clients
    requirements, but also satisfies my stakeholders.
    These interviews may also allow me to exceed my
    clients requirements. My stakeholders can also
    offer me valuable advice and suggestions.
  • Functional qualities I will need to consider
    functional qualities in my design process to
    ensure that the end result actually works and is
    fit for purpose.
  • Model/testing I will need to construct a model
    and test the model after I have designed my
    developments. I will then need to get feedback
    from my client in order to further develop my
    design to the final design stage.
  • Style I will need to consider the style of my
    design and ensure that my client thinks that my
    chosen style/s are suitable for his
    needs/requirements.
  • Finish I will need to consider the finishing's
    I will use in my final design as this is a big
    part of making the project suitable for both my
    client and the location it would be used in.
  • Harmony The design will need to be in harmony
    with its surroundings. I will need to get
    feedback from my client in order to ensure that
    it is.

Planning Evaluation My planning was fairly
accurate until the conceptual stage. My Concepts
took far too long, and as a result, I fell
severely behind. I was forced therefore, to alter
the dates I started everything planned after my
concepts. This effectively pushed my planned
deadline forward 4 weeks. It was also difficult
to effectively contact my client as he was often
busy and misinterpreted my emails. Because of
this I fell behind even more, as I struggled to
find things to do while awaiting contact, and was
often left with nothing to do. My record of
action was kept constantly up to date and
accurate throughout the process. Everything was
effectively recorded. I entered my record of
action on a regular basis and as such, it was not
difficult to keep a record of everything done.
Next time I would make use of a Gantt chart so
that I can easily see when I go over the planned
date for each key stage, and can make plans to
catch up. I would also ensure I had a more
reliable way to contact my client next time, such
as a phone number or face to face meetings on a
regular basis, so that misunderstandings of
designs, and long periods between contact does
not prevent me doing the work.
30
Expert (Stakeholder) I had a visit from an
electrical engineer called keshawa (found at
www.futureintech.com ) during the second term.
This answered a lot of my questions such as how
to effectively wire up my circuit/circuits, what
market opportunities are available, and what
alternative designs may be available. He made the
point that having batteries in parallel with a
capacitor would effectively hold charge better
than just a capacitor, as the capacitor would act
as a buffer, and the battery/s would store the
energy. Batteries store energy longer than
capacitors. He also suggested using a dynamo
style system to move the magnets through the
coils. This system would spin the magnet within
the coil as the tile is compressed, and will
continue spinning until friction stops it, after
the tile has decompressed. In this way the system
could harness A LOT more energy than originally
anticipated, however, due to size constraints,
this idea would need a lot more developing done
to ensure the tile stays thin enough to fit in
the required situations, and I simply do not have
the time to investigate any further down this
path, for this project. This is something that
could be considered in future developments,
however. It could also improve the design so that
it is industrial standard.

Clients Comments This is great, It is good to
see how the electrical wiring is going to be
incorporated into a single panel. Chris has
informed me that he had a meeting with an
electrical engineer recently and now has several
other options to consider. Aesthetically it is
very pleasing and I believe it is a very modern
looking tile..
32
  • Developmental Evaluation
  • My development design has met the functional
    requirements. It will produce and store its own
    energy, for use when a power outage occurs.
    Aesthetically it could be improved, which is
    something I will need to investigate further when
    I draw my final design. The wiring has been
    optimised to take up the smallest space possible,
    and to stay out of sight to ensure aesthetic
    qualities are maintained. The wiring will have
    some slack in the area that it crosses from the
    bottom half, to the top half of the tile, through
    the underlay, as it is crucial that the movement
    of the tile does not sever the ties between the
    two halves of the tile.
  • After talking with an industrial expert I have
    many things to think about. We discussed several
    alternatives and options that I will need to
    consider when further developing my design, and
    more that could be considered if I were to move
    onwards to an industrial business stage. These
    alternatives/options include
  • Using batteries instead of capacitors as they
    hold their charge longer.
  • Setting up several parallel, series circuits,
    rather than one series circuit, to increase the
    voltage/ current.
  • Using a dynamo system rather than a spring system
    to enhance the amount of energy collected.
  • Client (C W) Chris has really taken full
    advantage of the industrial technician, and
    further developed this idea I look forward to see
    how the advice given to him is put into this
    project.
  • Stakeholder (Derek M)
  • Things have moved on from the concept stage I
    really can see the finished product being quite
    an outstanding design especially aesthetically ,
    it is nothing like I originally had expected this
    project to turn out.
  • With the advice and the range of alternative
    options the electrical engineer gave Chris, this
    design does have the potential to be a viable and
    efficient product. It will be seen at the scaled
    model stage if Chris has been able to demonstrate
    the possibility of producing an electrical
    current by the compression of the tile in the
    vertical plane.

33
Model Evaluation My model has shown me that
having a solid mass of underlay between the
bottom of the tile, and the top, will limit the
amount that the tile decompresses significantly.
Therefore, I have decided instead, to merely
surround each magnet with an octagonal off-cut of
underlay, allowing space between each section,
for the underlay to spread out, and thereby
compress significantly more. Because of the empty
space this will cause in the tile system, it may
be possible to pump hot air through the tile
system, thereby creating under floor heating. The
tile will possibly be warmer anyway, because it
is similar in design to EXPOL EPS foam board.
This is something that could be looked into if
further investigation were to be made at a later
date.
34
Final Conceptual Design Drawing
Stakeholder Evaluation A very thorough and well
thought out design. Chris has used the advice
given to him well and has enhanced his original
idea without any or little compromise. It meets
all the requirements of the original brief and
specifications. His client has stated that he
could now develop this conceptual idea (proven by
testing and modelling) further to a production
stage with the future support of industrial
backers.
35
Final Conceptual Design Drawing
Clients Evaluation Overall this is what I wanted
from Chris, after seeing his initial design
concepts a design that is functional in the
sense that it can produce an sustainable,
efficient power source. This can be adapted from
this idea into a variety of different, yet
similar models used in a range of locations. His
Model has demonstrated effectively that it is
viable outcome which could now be taken a step
further by looking for a company that could help
him create this into a actual marketable product.
36
Final Design Evaluation My Final design has met
all aesthetic and functional requirements as
specified by my client. It will light doorways
and stairways in the event of a power cut, by
automatically switching on LEDs in the upper
section of the tile. It is entirely reliant upon
itself as it produces its own power through
electro-magnetic induction and all wiring and
components are contained within the tile. It
looks attractive and can be personalised by
adding different coloured acrylic to the top,
different colour LEDs, or by painting the wood
under the clear acrylic, during the construction
process. The planning for the written/designing
stage of this project was very inaccurate after
week 6. I started falling behind as I kept
adding in extra things, and my conceptual,
developmental, and final designs took longer to
complete than originally planned. My client has
proved very difficult to get in touch with, which
has also held me up a lot. The record of my
actions was however, accurate. It was not
difficult to keep constant records, but was
difficult to stick to the timeline I had
planned. I feel the correct materials were
considered for use in my project. I did change
the underlay from a solid mass between the top
and bottom, to several smaller masses surrounding
the magnets. This allowed the tile to compress
much further and with less force. The materials
worked as expected (aside from the underlay). The
final design meets all specifications set. The
final design reflects the requirements and wishes
stated in the Design Brief. Aesthetically, the
design is very attractive, and has come out
better than expected. For a future development
(but one that I will not pursue in this project
because of time restraints and un-necessity) ,
specialized mats could be designed in such a way
that when a door opens, it compresses the mat,
both to allow the door room to open, and also to
add functionality to another un-harnessed energy
source that is everywhere the opening and
closing of doors. I have not had to consider
electrical safety throughout the design and
build process as the whole system is under 18V.
I have addressed the tripping hazard by rounding
the edges of the top of the tile so that a foot
would simply glide over the raised edge. This is
an ethically based project because it revolves
entirely around sustainable energy generation.
The tile is safe for the planet because it is
designed to be used for an extended period of
time, meaning that a tile would rarely be sent to
the dump. As such, this tile is good for the
planet earth and safe for everyday use. Client
(C W) Chris has produced an excellent scaled
model which fully demonstrates to me how this
unique idea can work. I am looking forward to him
producing a full scale working project which can
be used to demonstrate to others the qualities
and potential of this project. He has solved many
of the problem that has arisen well with the
advice from wider community stakeholders. Stakeho
lder (Derek M) Overall this is an excellent
example of an Idea that has been developed,
tested and modeled. Chris has used the advice
given by the expert technician from future in
tech to full advantage. It total meets the
client expectations and the requirements of the
brief. The key design elements that stand out is
the simplicity and creativity of a scientific
concept developed and made into a existing
model. There has been the occasional problems
with the communication with the client though
through no fault of Chris W, this has held up
certain evaluations but with his ability and
knowledge Chris has been able to continue with
the modeling of this idea because of the clear
brief and requirements the client has needed.
37
  • Final Brief
  • I will produce a solution for my client and
    stakeholders. It will need to be entirely reliant
    upon itself and be able to light doorways and
    stairwells efficiently and safely. This final
    solution should incorporate the magnet-coil tile
    solution demonstrated in my model, but should be
    a much improved version.
  • Materials
  • Transparent, blue acrylic for the tile top.
  • Carpet underlay for the compressing material
    sandwiched between the upper and lower tile.
  • Copper wire for the coils and insulated copper
    wire for the system wiring.
  • Neodymium rare earth magnets for sitting inside
    the coils and moving in order to generate
    electricity.
  • MDF wood for the base of the tile and wood for
    the stairs or doorways (wood type depending upon
    situation).
  • Cost To be kept to a minimum.
  • Safety The tile needs to be able to compress and
    decompress without being a tripping hazard.
  • Construction
  • Needs to be strong.
  • Needs to be durable.
  • Needs to be efficient.
  • Needs to be user friendly.
  • Finish A high quality finish of acrylic trimmed
    with rounded wood edges is required.

Here in figure 1 I am using a band saw to cut the
bottom of the tile to size so that the other
components of my design fit on top without the
lower layer being visible, and without the top
layers overhanging it. This was the first stage
as I needed to have a base to work from.

In figure 2 I am drilling holes in the result of
figure 1. These holes are to contain the coils
which I will create further on in the
construction process. In both figure 1 and 2 I am
wearing safety glasses to ensure no flying bits
of wood damage my eyes.

In figure 3 I am gluing the two layers of
underlay I previously cut, together. This is the
model version. I am using respiratory equipment
because ventilation within the room was not
adequate at the time I was gluing. Figure 4 is a
close up of the underlay material and the pot of
glue.

figure 5 and 6. All 3 pictures are the final
version under construction.

In figure 10 I am winding one of the coils for my
project. These coils will be set into the holes I
drilled in figure 2 and will be part of the
energy producing system in the tile.

Figure 11 is the top portion of the final product
in its finished form. Figure 12 is the
same as figure 11 except the LEDs are on,
showing how the tile would look when
active. Figure 13 is the underside of
the top portion of the final product. It doesnt
yet have the magnets attached in this picture, it
shows only the wiring.
42
In figure 14 I am soldering the wires of my
project together so that the coils are connected
to each other, to the batteries, and to the
LEDs. This is because to charge the batteries
and run the LEDs the components must all be
connected in a circuit. In figure
15 I am demonstrating my final product in a
replica of its planned environment

Production of an Outcome
  • Client (C W)
  • Chris has produced an excellent Prototype which I
    could very easily use to support Chris in
    introducing this to future stakeholders to
    develop this into a product that could be sold.
  • I think Chris has communicated his design ideas
    very effectively and though we had several
    challenges with keeping in contact due to my busy
    schedule this has not hindered him to his credit.
  • I am extremely happy with the final prototype it
    is fit for the purpose of creating a prototype
    to demonstrate this design concept to potential
    financial backers and manufactures. He has
    produced more than I had originally expected.
  • Stakeholder (Derek M)
  • Referring back to the final brief and the
    location in which this project can go this fully
    demonstrates to all stakeholders that this is a
    viable solution.
  • The key design elements that stand out is the
    excellent materials he has used to produce a
    very visually appealing tile. And in the stair
    situation which gives a clear example of all of
    the concepts possibilities
  • Given the constraints of cost of materials this
    outcome could be developed further which will
    require a stakeholder to inject more money into
    producing this and further
  • Overall an excellent presentation of the original
    brief and its development though the many stages
    to get to this Prototype.

44
Final solution/Evaluation Overall my project was
a good design. It meets my clients expectations
and requirements because it is fit for the
purpose my client wanted to be demonstrated to
potential further stakeholders. It meets the
specifications set in the final brief of
materials because all of the materials specified
were used how they were specified, no more, no
less. It meets the cost specifications because
the cost was kept as low as possible by using
materials that were set to go to the dump, and by
using cheaper materials. The safety specification
was met as the tile has been constructed in such
a way as to allow a foot to simply glide over the
edge, rather than get caught on it. The
construction requirements were met as the final
solution is strong, durable, efficient, and user
friendly. The final solution has a very nice
transparent blue acrylic finish, trimmed on the
edges with thin rounded strips of wood.
