Altschuller's Contradiction Matrix and Bartini-Kuznetsov's LT - Table represent two different tools for solving inventive problems based on the same dialectical principle. It starts from the premise that there are contradictions at the root of every

Technical contradiction occurs when the system improves one parameter, which automatically causes the deterioration of some of its other parameters. In such a situation, instead of usual acceptance of the optimization of the solution to the problem,
