TRIZ

Question 1

Define TRIZ

Answer 1

• The theory of inventive problem solving
• Derived from studying patterns of innovation in patents
• Takes a systematic, data-driven approach to innovation rather than spontaneous brainstorming
• Uses inventive principles (e.g. removal - lunar landing) and engineering parameters (e.g. durability of moving object) that are the basis for technological innovations
• Improves existing systems/ products by resolving contradictions in their design (improving one attribute of the system can lead to deterioration in other attributes e.g. strength/ flexibility)

Question 2

What is the TRIZ problem solution process?

Answer 2

1. Identify the specific problem (e.g. ketchup bottle being upside down falling over)
2. Make the problem more general (how to make things more stable)
3. Identify a general solution using TRIZ principles(give them a larger base)
4. Then apply the general solution to the problem to determine a specifc solution (make the bottle cap wider)

Question 3

Give an example of when TRIZ was applied?

Answer 3

Lunar landing bulb filament - removed a feature to improve the design - a principle of trip

Question 4

What are the steps within the innovation process?

Answer 4

1. Identify opportunities/ problems
2. Generate ideas
3. Evaluate and select ideas
4. Develop and prototype
5. Test and iterate
6. Implement and scale
7. Monitor and evaluate

Question 5

Where does TRIZ fit into the innovation process?

Answer 5

1. Generating ideas - coming up with a new product idea
2. Develop and prototype - Solving problems that occur during the prototyping phase - finding alternative solutions
