Q

What is functional decomposition?

A
  1. Represent energy, material, and signal inputs and outputs of the product
  2. Divide the black box into subfunctions (3-10) without specifying solution concepts

Q

What action decomposition?

A
  • Breaking down a problem into a set of actions
  • Used for products with simple technical functions involving a lot of user interaction

Q

What is needs decomposition?

A
  • Breaking down a problem into a set of needs
  • Used in products where form is the primary problem not working principles or technology

Q

What is the purpose of external search?

A
  • Finding existing solutions to the overall problem and subproblems
  • Occurs throughout the development process
  • Existing solutions are cheaper and faster to implement

Q

What are 5 guidelines for internal search?

A
  1. Suspend judgement
  2. Generate a lot of ideas
  3. Welcome seemingly infeasible ideas
  4. Create many sketches
  5. Build sketch models

Q

What are some hints for internal search?

A
  1. Make analogies
  2. Wish and wonder
  3. Distort ideas
  4. Use related stimuli
  5. Set quantitative goals
  6. Use the gallery method

Q

What is systematic exploration?

A
  • As a result of the external and internal search activities, the team will have collected tens or hundreds of concept fragments—solutions to the subproblems. Systematic exploration is aimed at navigating the space of possibilities by organizing and synthesizing these solution fragments

Q

What are the two methods of systematic exploration?

A
  1. Concept classification tree
  2. Concept combination table
17
Q

What is a concept classification tree and its benefits?

A
  • Divides possible solutions into classes
    1. Pruning of less-promising branches
    2. Identifying independent approaches
    3. Ensures equal consideration of all branches
    4. Refinement of decomposition for specific branches
18
Q

What is a concept combination table?

A
  • The concept combination table provides a way to consider combinations of solution fragments systematically
  • Columns correspond to subproblems
  • Entries correspond to solution fragments
  • Potential solutions are formed by combining a fragment from each column
19
Q

What are three guidelines for concept combination tables?

A
  1. Eliminate independently infeasible fragments
  2. Concentrate on coupled subproblems
  3. Number of columns should stay under 4
20
Q

What are some relevant reflection questions?

A
  • Has the solution space been fully explored?
  • Are there alternative function diagrams?
  • Are there other ways to decompose the problem?
  • Have external sources been thoroughly pursued?
  • Has the whole team contributed?
21
Q

What is the 6-3-5 method?

A
  • 6 team members, each generates 3 concepts, 5 rotations of feedback
