Contradiction Identification
Identify technical and physical contradictions in a system, providing resolution paths for each.
Stages
Stage 1: Function Model Construction
Build substance-field model of the system using function-model-construction SOP. Annotate useful, harmful, and insufficient interactions.
Stage 2: Contradiction Matrix Lookup
For each identified technical contradiction (improving parameter vs worsening parameter), query the 39×39 TRIZ contradiction matrix via contradiction-matrix-lookup SOP.
Stage 3: Separation Principle Selection
For physical contradictions (same parameter must be both X and not-X), identify applicable separation principles (time, space, condition, scale) via separation-principle SOP.
Minimum Yield
| Metric | Floor |
|---|
| Technical contradictions identified | ≥2 |
| Physical contradictions identified | ≥1 |
| Resolution paths per contradiction | ≥2 |
| Applicable principles listed | ≥4 |
Available SOPs
| SOP | Role |
|---|
| function-model-construction | Stage 1 — build substance-field model |
| contradiction-matrix-lookup | Stage 2 — query matrix for principles |
| separation-principle | Stage 3 — resolve physical contradictions |
| triz-principle-application | Post — apply selected principles |
Available SOPs
Optional, no fixed order; the final leaf is always a sop.
| SOP | When to use |
|---|
| contradiction-matrix-lookup | Query the 39x39 TRIZ contradiction matrix to find recommended inventive principles for a given technical contradiction. |
| function-model-construction | Build substance-field functional model of a system, annotating useful, harmful, insufficient, and excessive interactions. |
| separation-principle | Apply time/space/condition/scale separation to resolve physical contradictions where the same parameter must satisfy opposing requirements. |
