Physical contradiction

Physical contradiction is a parametric model of the problem that emerges when two justified contradictory demands are placed upon a single parameter of an object to provide the required result.

Overview

A physical contradiction refers to a situation where a single parameter of an object is subjected to two conflicting requirements. The focus on a single parameter distinguishes it from an engineering contradiction (which involves two different parameters). However, both types of contradictions are directly interconnected and can be derived from one another.

Note that if one of the required parameter states cannot be justified, then there is no physical contradiction, rather you have a solution.

The physical contradiction is more precise than the engineering contradiction because the problem is modeled using a parameter belonging to only one component. This makes it clear from the outset which component should be addressed with the recommendations derived from TRIZ.

Models of solutions for the physical contradictions are inventive principles. The tool that is used to translate the engineering contradiction into inventive principles is the algorithm for resolving physical conradictions.
