Abstract
Among the open research issues in the field of inventive design, a careful attention should be dedicated to the definition of means to measure and improve the efficiency of educational and training processes as well as to assess the benefits of the introduction of TRIZ expertise into R&D and engineering teams. In fact, while TRIZ methods and tools have gained a certain acknowledgment as a means to improve problem solving and inventive design skills, a dominant model about its introduction in an industrial organization is still missing. The paper presents a study aimed at measuring the impact of TRIZ learning (tools and logic) with respect to individuals’ talent. The paper proposes an original methodology to investigate human approaches to inventive design tasks: definition of the test (Sample group and control group, Inventive problems); evaluation criteria (Aptitude to follow a logical problem analysis path; Aptitude to explore various perspectives of the problem; Aptitude to generalization; Overall correctness of the problem analysis task; Completeness of the analysis); comparison and correlation criteria (Pearson correlation). The proposed investigation methodology is clarified through the description of an exemplary application in design courses at Politecnico di Milano and at the Università di Firenze.
