Show Answers:

  1. Competitive edge from designs
    • Matching product or service characteristics with customer requirements
    • Ensuring that customer requirements are met in the simplest and least costly manner
    • Reducing time required to design a new product or service
    • Minimizing revisions necessary to make a design workable
  2. Idea generation
    • Getting an idea of what you want to do, through benchmarking, reverse engineering, perceptual map
    • -> Product concept
  3. Feasibility studies
    • Market analysis - are customers going to buy it
    • Economic analysis - if you add an ingredient will it raise price too much
    • Technical / strategic analysis - needs to align with strategy
    • -> performance specs
  4. Rapid Prototying
    • Build a prototype
    • Test the prototype
    • Revise and retest
  5. Functional Design
    • Reliability - probability that a part or product will perform is intended function for a specified period of time
    • Maintainability - ease of repair
    • Usability - ease of use
  6. Usability
    • Ease of learning
    • Ease of use
    • Ease of remembering how to use
    • Frequency and severity f errors
    • User satisfaction with experience
  7. Simplification
    reducing the number of parts, assemblies, or options in a product, 1st thing you do
  8. Standardization
    Using commonly available and interchangeable parts, results in higher volume production and purchasing, lower investment in inventory
  9. Modularity
    Combining standardized building blocks or modules to create uniquee finished product, used a lot with electronics
  10. Design for manufacture
    • Design a product for easy economic production
    • avoid tool, minimal handling
  11. DFM guidelines
    • Minimize number of parts and subassemblies
    • Avoid tools, separate fasteners and adjustments
    • Use standard parts when possible and repeatable
    • Design parts for many uses, and modules that can be combined in different ways
    • Design for ease of assembly, minimal handling
    • Allow for efficient and adequate testing and replacement of parts
  12. Concurrent Design
    Simultaneous design of products and processes by design teams
  13. Computer aided design (CAD)
    Assists in creation, modification, and analysis of a design
  14. Computer-aided engineering (CAE)
    tests and analyzes designs on computer screen
  15. Computer-aided manufacturing (CAM)
    Ultimate design to manufacture connection
  16. FMEA Failure mode and effects analysis
    systematic method of analyzing product failures
  17. Fault tree analysis (FTA)
    A visual method for analyzing interrelationships amoung failures
  18. Value analysis(VA)
    Helps eliminate unnecessary features and functions
  19. Extended producer responsibility (EPR)
    holds companies responsible for their product even after its useful life
  20. Quality Function Deployment (QFD)
    • Translates voice of customer into technical design requirements
    • Displays requirements in matrix diagramsCoordinates the design process
    • "house of quality"
  21. Benefits of QFD
    • Better understanding of customer demands
    • Better understanding of design interactions
    • Involved manufacturing in design process
    • Breaks down barriers between functions and departments
    • Provides documentation of design process
  22. Robust design
    Designed to withstand variations in environmental and operating conditions
