Triz
1. History
Altshuller founded this methodology. He studied a lot of patents and created this methodology.
These were his finds.
a. All Innovations emerge from very small number of Inventive Principles.
žb. Technological Evolution Trends are highly predictable. Strongest solutions destroys
conflicts or tradeoffs.
žc. Strongest solutions converts Harmful elements of a system into useful resources.
2. Philosophy
Ideality - all products move towards Ideality.
Resource - Use of available resources
Functionality - divide the task into function and verb.
Contradiction
Space/Time/Interface
3. Tools
1. S-curves
2. Triz Inventive Principles
2a. Contradiction matrix.
3. Trends of Evolution
4. TRIZ database
5. S-field Analysis
6. 9-windows or System Operator.
