2. Concept development phase
PRODUCT CONCEPT IS APPROXIMATION OF TECHNOLOGY, WORKING PRINCIPLE TO FORM OF PRODUCT.
CONCEPTUAL SKETCH IS A THREE DIMENSIONAL MODEL, WITH BRIEF TEXTUAL DESCRIPTION
SUCCESSFUL PRODUCT DEPENDS ON THE QUALITY OF UNDERLYING CONCEPT

3. COMMON CAUSES OF FAILURE IN PRODUCT CONCEPT
ONLY ONE OR TWO ALTERNATIVES, PROPOSED BY MOST ASSERTIVE MEMBER.
INVOLVEMENT OF ONLY ONE OR TWO PEOPLE IN THE PROCESS
INEFFECTIVE INTEGRATION OF POTENTIAL SOLUTIONS
FAILURE TO CONSIDER ENTIRE CATEGORIES OF SOLUTIONS

4. FIVE-STEP CONCEPT GENERATION METHOD

5. STEP 1 – CLARIFY THE PROBLEM
Clarify the problem consists of developing a general understanding and then breaking the problem down into sub problems if necessary
TO DESIGN A BETTER HANDHELD ROOFING NAILER
DECOMPOSE A COMPLEX PROBLEM INTO SIMPLER SUBPROBLEMS
Many design challenges are too complex to solve as a single problem and can be usefully divided into several simpler sub problems.
In some cases, the design problem cannot readily be divided into sub problems.

6. FUNCTIONAL DECOMPOSITION
BLACK BOX
3 – 10 SUBFUNCTIONS

7. Step 2: search externally
Aimed at finding existing solutions to both the overall problem and the sub problem clarification step.
External search for solutions is essentially an information-gathering process.
INTERVIEW LEAD USERS
Building contractors, house builders
CONSULT EXPERTS (technical rep., product engineer)
SEARCH PATENTS (
SEARCH PUBLISHED LITERATURE
BENCHMARK RELATED PRODUCTS

10. STEP 3: SEARCH INTERNALLY
Internal search is the use of personal and team knowledge and creativity to generate solution concepts.
Called BRAINSTORMING, this type of search is INTERNALLY in that all of the ideas to emerge from this step are created from knowledge already in the possession of the team.
4 guidelines are useful for improving both individual and group internal search:
Suspend judgment
Generate a lot of ideas
Welcome ideas that may seem infeasible
Use graphical and physical media

11. Tips for generating solution concepts
MAKE ANALOGIES
WHAT OTHER DEVICES WOULD DO THE SAME TASKS
WISH AND WONDER
I WONDER…
I WISH…
USE RELATED STIMULI
USE OTHER’S IDEAS TO GENERATE FURTHER IDEAS
USE UNRELATED STIMULI
SET QUANTITATIVE GOALS
USE GALLERY METHOD

12. STEP 4: EXPLORE SYSTEMATICALLY

13. EXPLORE SYSTEMATICALLY
CATEGORIZE THE SOLUTIONS OF SUBPROBLEM
