Technical Contradiction

INTRODUCTION
English translation pending.
CORE DEFINITION
In TRIZ, a technical contradiction exists when improving one parameter of a system worsens another, for example raising aircraft speed at the cost of higher fuel consumption. Naming the pair converts a vague feeling that something is hard into a precise statement that A and B are in conflict, which can then be entered into the contradiction matrix to obtain recommended inventive principles. It must be distinguished from a physical contradiction, where a single parameter is required to be two opposite things at once.
SCAFFOLDING EFFECT
Reduce cognitive load
- Use parameter pairing: name the parameter being improved and the one being degraded by it. - Use conflict statement: write the contradiction explicitly as A improves while B simultaneously worsens. - Use type check: confirm it is a technical rather than a single-parameter physical conflict indeed.
Anchor fast decisions
A technical contradiction is the situation where improving one parameter degrades another, such as speed against fuel consumption. Stating it precisely converts a vague difficulty into a specific conflict of A against B, which the contradiction matrix can address. It differs from a physical contradiction, where one parameter must satisfy opposite requirements at once.
