12
The Design Process

• Definition of Engineer
• The public usually thinks of someone skilled in
  Mathematics, Science, and Fundamental Technology.
• They usually dont think of someone with
  Creativity

13
The Design Process

• Definition of Engineer
• en-gi-neer (n) One who employs the innovative and
  methodical application of scientific knowledge
  and technology to produce a device, system, or
  process, which is intended to satisfy human
  needs.
• - American College Dictionary

  and technology to produce a device, system, or
  process, which is intended to satisfy human
  needs.
• - American College Dictionary

15
The Design Process

• Definition of engineer includes
• Innovative AND Methodical
• These two characteristics are in COMPETITION!
• This is what makes design difficult

16
The Design Process

• Definition of engineer also includes the term
• Satisfy human needs
• This emphasizes the necessity to determine users
  needs and the ethical application of the
  technology.

17
The Design Process

• Definition of Design
• Engineering design is the process of devising a
  system, component or process to meet desired
  needs. It is a decision-making process (often
  iterative), in which the basic sciences,
  mathematics, and engineering sciences are applied
  to convert resources optimally to meet a stated
  objective. Among the fundamental elements of the
  design process are the establishment of
  objectives and criteria, synthesis, analysis,
  construction, testing and evaluation.

19
The Design Process

• Key to good engineering design is to follow a
  design process
• This gives structure within which creativity can
  occur in an efficient and effective manner.
• Design Process can be
• Prescriptive
• Descriptive
• Hybrid of the two

20
The Design Process

• Prescriptive Design Process
• An exact process, or systematic recipe, for
  realizing a system.
• Example of a systematic process for problem
  identification and requirements selection

Computer Engineers, Ford and Coulston
21
The Design Process

• Descriptive Design Process
• A less formal process that incorporates typical
  design activities with less emphasis on exact
  ordering.

Computer Engineers, Ford and Coulston
22
The Design Process

• In between Descriptive and Prescriptive Design
• It is not always clear which of the two types you
  should use, or are using.
• Regardless, there are good reasons to using such
  design processes
• Formalize thought processes to ensure good
  practices are followed, (e.g. dont generate a
  concept without a good set of specifications).
• Keep all team members synchronized.

23
The Design Process

• Iteration in design
• In general, iterations are required before a good
  design can be achieved.
• However, changes to the design have substantial
  costs in time and money.

Computer Engineers, Ford and Coulston
24
The Design Process

• Elements of the Design Process
• Problem Identification
• Research
• Requirements Specification
• Concept Generation
• Design Phase
• Prototyping
• System Integration
• Testing
• Delivery
• Maintenance

Computer Engineers, Ford and Coulston
25
The Design Process

• Technology specific design
• Often there are several subcomponents that must
  be designed within a project.
• These can make the design process specific to
  that project.

Introduction

• Course Overview
• The Design Process
• Capstone Projects

27
Project 1 Adapted Kayak

• Client Dr. Kevin Taylor (KINE) and the Central
  Coast Assistive Technology Center
• Design a joystick and sip-and-puff interface to a
  trolling motor to paddle a sea kayak

28
Project 2 Sensory Stimulation Room

• Client VTC Enterprises
• Definition of the Problem
• There are 70 individuals in this program who have
  sensory integration issues. They need the
  opportunity to experience sensory stimulation
  through activity that is adult appropriate and
  not infantile
• Most people think there are 5 senses however
  there are 7.
• This room would have activities which stimulate 7
  senses
• Seeing
• Hearing
• Tasting
• Smelling
• Feeling
• Vestibular
• Propriaceptic

29
Project 3 Chin Switch Environmental Remote
Controls

• Sponsor VTC Enterprises
• Definition of the Problem
• There are several individuals who are cognitively
  aware however, whose bodies act as a paraplegic.
  
• At this time they are fully dependent upon others
  to turn on/of lights, control temperatures,
  radios, and to get assistance.
• A room designed with remote controls operated by
  a chin switch would be ideal!!
• A call button, entertainment center, radios, TV,
  VCR/DVD player, lights, stereo, etc

30
Project 4 Personal Obstacle Detection System

• Sponsor VTC Enterprises
• Definition of the problem
• Design a system that will help an individual who
  is blind avoid obstacles in the workplace

31
Project 5 Vision-Based Localization System for
Autonomous Vehicles

• Sponsor Dr. Chris Clark
• This project will serve as part of a larger
  project, the Cal Poly Autonomous Transportation
  System (CPATS). The goal of the CPATS is to equip
  a group of Cal Poly golf carts with intelligent
  control capabilities so that they can
  autonomously transport students, staff, faculty
  and visitors around campus.
• This portion of the CPATS will involve vehicle
  localization - estimating the position of a
  vehicle within a global coordinate frame (e.g.
  campus). First, the vehicle state will be
  predicted with wheel encoder measurements. Then,
  a monocular vision system will be used to detect
  unique artificial landmarks and/or natural
  landmarks that can provide a direct measurement
  of the vehicle's state within the global
  coordinate frame. This measurement will be fused
  with the state predicted by wheel encoders to
  produce an optimal state estimate. The process
  should be displayed with a Graphical User
  Interface.
