39 Parameters

39 Parameters are the contradictions that can be found in a system or object. Each of the technical parameters can be interpreted as an improving or worsening factor in a system. It is used to create the Contradiction Matrix that will help you to solve your problems easily by giving you the suggested 40 Principles.
