A New set of Measurement Standards for a Circuit Breaker Application

During the years, the Standard Solutions (SS) have been reformulated multiple times, through redefinition, simplification and exemplification. The original 76 Standard Solutions are grouped in classes. The fourth class contains the standards for measuring and seems to be the less investigated.In this paper, the standards related to problems of measure are reformulated and classified into three main groups: (1) direct measuring of the desired parameter, (2) changing the problem in order to not measure it and (3) obtaining an indirect measure of the desired parameters.To be more systematic, a rigorous ontology drives the user to define what has to be measured (field or substance), where (internal or external to the system) and how (exploiting an already existing resource or if a new substance/field has to be introduced or if already present). Authors applied the new approach in several industrial application. A case study, involving a multinational company in the field of high-tension vacuum circuit breaker, is proposed and discussed to highlight strengths and limitations of this new set of standards vis a vis the classical Standard Solutions. TRIZ experienced PhD students from the University of Bergamo repeated this test so as to have another point of view for this comparison.
