The 40 Inventive Principles are TRIZ’s most-used library of solution patterns for breaking trade-offs. The canonical list is widely published by TRIZ bodies and teaching resources.
This page turns the principles into a matrix workflow you can run with AI in Jeda.ai: principle → translation → concept direction → risk → fastest test.
What this page delivers (professional output)
You will end up with a 40-row matrix where each row contains:
- Principle # + name
- “AI translation” (action verb)
- One context-specific concept direction
- Risk / new harm
- Fastest falsifiable test + KPI
This matters because teams often stop at “list principles.” A matrix forces execution.
How to run Inventive Principles with AI in Jeda.ai (Matrix)
Method 1 — AI Recipe Templates (AI Menu)
- Open your board → AI Menu / AI Recipes.
- Go to TRIZ → select Inventive Principles.
- Input:
- Contradiction statement: Improve X → worsens Y
- System context
- Constraints (must-not-change)
- Generate the 40-row principles matrix.
- Score and shortlist 5–8 principles. Expand only those into prototypes/tests.
