Network of contradictions analysis and structured identification of critical control parameters

AbstractThis paper aims at improving the efficiency of an inventive problem solving process for complex systems, by reducing the iterations due to the emergence of new problems caused by the implementation of the identified solution. The proposed algorithm guides the problem solver in choosing the most important contradiction to be faced with ARIZ85-C and provides further instructions about the best approach to be followed. Such purpose is achieved by organizing the characteristic parameters of a Technical System according to a specific metric, which allows both the construction of a Network of Contradictions and the definition of criteria for identifying priorities. An exemplary application of the proposed method has been carried out in the field of exhaust noise in 4-stroke engines
