Study Notes

Concept Generation

  • A product concept is a description of the technology, working principles, and form of the product. It outlines how the product satisfies customer needs.
  • Concepts are usually expressed as sketches or three-dimensional models, often accompanied by textual descriptions.
  • Concept generation starts with customer needs and target specifications.
  • Outputs are a set of product concepts for final selection.
  • The process includes steps like (CN) Mission Statement, (TS) Identify Customer Needs, (GPC) Establish Target Specifications, (SPC) Generate Product Concepts, (TPC) Select Product Concept(s), (SFS) Test Concept(s), (PDD) Set Final Specifications, Plan Downstream Development, and Plan Development.

Five-Step Method

  • Step 1: Clarify the Problem (CtP): Clarify the problem by decomposing it into subproblems. Problem decomposition is breaking a complex problem into simpler parts.
  • Step 2: Search Externally (SE): Gather external information using methods like lead user interviews, expert consultation, patent searches, literature searches, and competitive benchmarking.
  • Step 3: Search Internally (SI): Gather internal insights through activities like suspending judgment, generating numerous ideas, welcoming seemingly infeasible ideas and making plenty of sketches. Internal searches may involve creating simple physical models.
  • Step 4: Explore Systematically (AES): Investigate systematically; classifying ideas, combining concepts and utilizing integrated solutions. Sketch models are important.
  • Step 5: Reflect on Solutions (RotS): Reflect on the solutions and processes. Use constructive feedback.

Generating Concepts

  • Experienced individuals can generate concepts, but methods like analogies, asking "what if...?" or "wish we could...?" encourage ideation and new possibilities.
  • Consider related problems, biological analogies, and considering analogous tools or devices from different fields of application.
