FBS ontology to extend the efficacy of 40 Triz inventive principles

The TRIZ inventive principles are a set of problem solving guidelines universally tested and accepted by academic and industry. This article offers a review of this tool through the formalism of Function Behaviour Structure theory in order to enlarge the resolutive space and increasing at the same time the user's awareness about the solutions found. It is further proposed a test running on engineering students and researchers, based on the comparison between the original and the reformulated principles, for the resolution of two case studies.
