Concept Generation
JikoFit Continued
Problem Objective
Economic Stimulation
  • Design a low cost, sustainable, and culturally
    appropriate cooking system for use by poor and
    marginalized people in the developing world. The
    system should utilize an appropriate fuel source.
    A business centered on the fabrication of such a
    system should be considered to serve a market of
    people who earn less than 2/day. The design
    should be such that it can be used as a model for
    similar villages around the world.
  • Cultural Parameters
  • Majority of the cooking is done inside the house,
    which releases toxins, into the air, which is
    then trapped inside the house, creating a health
    problem
  • Children have died due to this indoor air
    pollution.
  • Since most of the cooking is done with charcoal,
    there is a large amount of deforestation.

For concept generation, many different ideas
where generated. All of them had some positives
and negatives
The combustion chamber is specifically designed
to optimize efficiency of burning fuels. There is
a special ring inside the chamber designed to
maximize airflow. It creates turbulence that
makes unburned gases go to the center of the
combustion chamber. Below is a picture
from the Aprovecho Research Center explanation of
the characteristics of the Envirofit
One of the features of the JikoFit is the
insulation material. Compared to the Envirofit,
the insulation is much cheaper. The insulation
material will be made in Kenya, by Kenyans. In
turn, this will hopefully spark a new industry,
creating new jobs and opportunities for Kenyans.

Team JikoFit
Concepts
The five concepts methane, JikoFit(final
solution), solar energy, trapping emissions, and
vent. The selection criteria for the five
concepts were reduction of emission, fuel
consumption, and cooking time, an open flame,
cost, cultural sensitivity, and overall size.
Methane, JikoFit, and the vent, were the three
highest scoring, and they made it to concept
selection The JikoFit scored the highest
for concept selection, because it greatly reduced
emissions, sustained an open flame, and remained
culturally sensitive due to the fact that the
overall shape of the Jiko is already well known
in Kenya.
JikoFit Final Solution
Current Technology
  • Current cooking methods of Kenyan Households
    include cooking over an open flame, the Jiko, and
    the Envirofit cook stove.
  • Open Flame creates hazardous emissions that are
    dangerous to both adults and children, who are in
    the same room as the fire. Since the food is
    cooked inside the house, it releases these toxic
    emissions, harming the occupants. The open flame
    is very culturally sensitive
  • The Jiko has been the current solution to this
    problem, but it still has a considerable amount
    of emissions that it releases. It only slightly
    cuts down on deforestation, which is another
    problem in Kenya.
  • The Envirofit is a very well designed product
    that greatly reduces emissions, deforestation,
    and cooking time. However, the cost of the
    Envirofit ranges from 20-25 dollars. On average
    the Kenyans earn about 2 dollars a day, and
    cannot afford to have a Envirofit.

Cost Analysis

JikoFit
Our solution to the problem is the JikoFit.
Essentially, the JikoFit is a combination of the
current cooking method, Jiko, and the expensive,
but effective design of the Envirofit. The shape
of the JikoFit was taken from the Jiko, which the
Kenyans have come to comfortably recognize as the
hour glass shape. The incorporation of
the Envirofits effective design implements its
ability to reduce emission and cooking time
through a well designed combustion chamber. Also
taken from the Envirofit is the idea of an
insulating material between the combustion
chamber and the outer wall that retains heat, and
allows for shorter cooking time and reduced
amount of fuel consumption. To maximize
combustions, we incorporated the idea of
sustaining sufficient airflow to the combustion
chamber, through a cavity located below the fuel.
One of the major benefits of the JikoFit design
is the low cost of manufacturing. As you can
see, the total cost of manufacturing the JikoFit
is considerably less then the Envirofit, at 4
compared to 20. This falls just out of the
daily earning range of the average Kenyan
citizen, remaining at an affordable price. Even
though the price is triple that of the average
daily earning, they will have the ability to take
out a loan, with little to no interest. The
profit is not to make a considerable amount of
money, but rather to further the research of the
business. The cost was calculated to 3.98 by
adding the additional cost of labor and material
to the original cost of the Jiko. Since it is
the very similar in shape and size, the cost will
not vary to far from the Jiko.
