Intro To Design
  • Systematic Design Process
2
Design
  • A Creative Process
    • Not as well defined as analysis
    • Usually iterative
    • A design evolves
  • 5 steps
    • Problem definition
    • Research
    • Generate alternatives
    • Analyze and select solution
    • Test and reevaluate
  • Documentation
3
Step 1: Problem Definition
  • Identify the need/opportunity
    • Difficult for truly new concepts
    • "There is nothing more difficult and dangerous,
    •   or more doubtful of success,
    •   than an attempt to introduce a new order of things."
    •   Niccolo Machiavelli, The Prince (1513)
    • Perceived opportunity
      e.g. A quiet vacuum cleaner
4
The Problem Statement
  • Address the real need
    • Research
    • Background knowledge
    • Who is your customer?
  • Don’t assume a design
    • Concise
    • Flexible
      • Not too specific (details always change)
      • Allow for innovation
5
Criterion for success
  • Measurable Metrics
    • Cost
    • Performance
    • Safety
    • Environmental factors
    • Aesthetics
    • Reliability

6
Step 2: Research
  • Information categories
    • Existing solutions
      • Limitations
      • Advantages
    • Who is in this arena
    • Economic factors (willingness to pay)
    • Other factors (safety, aesthetics, environmental, etc.)
  • Information resources
    • Technical journals/Textbooks
    • Library catelog
    • Industrial Indices
    • The Internet
    • Patent offices (US and others)
7
Step 3: Generate Solutions
  • Creativity
    • Curiosity (don’t fear the unknown)
    • Openness to new experiences
    • Take risks
    • Multiple vantage points
      • Bottom-up (detail driven)
      • Top Down (See th whole picture)
      • Lateral Thinking
    • Concentration (“Focus Daniel-san)
8
Organize for Innovation
  • Teamwork
    • Variety of backgrounds
    • Differing points-of-view
    • Differing skill sets
  • Brainstorming
    • Acceptance of initial ideas – don’t critique
    • Praise innovative ideas
    • Stress quantity
    • Combine ideas
    • Record everything … analyze later
9
Step 4: Analysis and Selection
  • Functional analysis
    (does it do what is required?)
  • Ergonomics
    (does it fit the user?)
  • Safety and reliability
    (don’t feed the attorneys)
  • Economics (how much does it cost?)
  • Engineering analysis
    (will it survive in the real-world?)
  • Decision Process (use a decision matrix)

Decision Matrix

Step 5: Test and Implement
  • Prototype
    • Test new concepts for feasibility (reduce risk)
    • Get feedback from customer
  • Concurrent Engineering
    • Do things in parallel
      (take some risks to shorten schedules)
    • Project Planning – use a tool
      (e.g. Microsoft Project)
  • Documentation (as you design … not after)
    • Drawings
    • Memoranda
    • Technical Reports
    • Presentations
  • Intellectual Property
    (patents, copyrights, secrets … Oh My)
