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
