Méthodologie d’aide à l’innovation par l’exploitation des brevets et des phénomènes physiques impliqués

Abstract : The aim of this thesis work is the development of a methodology for knowledge extraction from patents to assist design engineers in the industrial problem-solving phase. The methodology is based on three pillars: definition, search / analysis and innovation. A comprehensive definition of the main function of the industrial system delimits the research field and allows the retrieval of initial keywords through a detailed analysis of what is currently available. The iterative patent search is based on functional decomposition and physical analysis. The analysis phase uses energy functional decomposition to identify energies, transmitted functional flows and physical phenomena involved in the energy conversion process in order to select potentially relevant physical effects. To delineate the exploration field we formulate search queries from a keywords database composed by initial, physical, and technological keywords. A discovery matrix based on the intersections between these keywords allows the classification of pertinent patents. The research for innovation opportunities exploits the discovery matrix in order to decipher the evolutionary trends followed by inventions. Opportunities are deduced from an analysis of the discovery matrix empty cells, an analysis of the evolution trends, and from changing the concept by energy converter substitution. We propose evolution trends constructed from the evolution laws of TRIZ theory, design heuristics, and rules of the art of the engineering. An application case concerning the study of the evolution and the proposal of innovative biphasic separation systems in deep offshore highlights the method.
