The 40 Inventive Principles of TRIZ

The 40 inventive principles are reusable solution patterns extracted from patent analysis. They turn vague creativity into a checklist of proven moves that have solved similar contradictions before.

A few worth knowing

• Segmentation — split an object into independent parts
• Asymmetry — change from a symmetrical to an asymmetric shape
• Local quality — make each part perform its own function in its own best conditions
• Dynamics — allow characteristics to change for optimal action
• Cheap disposables — replace expensive objects with cheaper disposable ones

A classic example: a bolt that is hard to reach is segmented into a captive screw (principle 1) so it never falls out. Same problem, a principle points you straight to the answer.
