Even if TRIZ is developing increasingly both in research and education, new users always encounter difficulties in their first attempts to practice it. In such situation, Altshuller's original contradiction matrix often appears as an "easy-to-begin-with" tool. However, while not being representative of what TRIZ really is, it continues to seduce new users, teachers and trainers. This article presents an innovative method for facilitating the use of the contradiction matrix, using a semantic similarity approach and case-based reasoning. © 2013-IOS Press and the authors.

This paper presents a simplification of one of the TRIZ methods, the Substance-Field Analysis (SFA). Applying TRIZ methods is often time consuming and therefore a barrier to its application in the industry. Our research group strives to simplify TRIZ methods to make their use more widespread. This SFA simplification was obtained during the implementation of a computer aided SFA. This implementation implies an ontological phase, which leads to the translation of the SFA terminological and conditional knowledge in a computer language. In addition to their operational interest, the chosen computer languages (Description Logics and First Order Logic) have formal interest for the SFA. The complexity of the application of SFA has regularly been reported by the TRIZ community. The SFA terminology suffers from a lack of normalization and the 76 Standards deployment is an empirical process. We propose a clarification of the Substance-Field Modeling terminology and a systematic process for deploying the 76 Standards. Thanks to Description Logics, the SFA terminology is formalized in an automatically consistency checked model and First Order Logic ensures the systematization of the 76 Standards deployment. © 2015 The Authors.

TRIZ (the Russian acronym for Theory of Resolution of Inventive Problems) is a methodology to guide the search for inventive solutions to one, or a few, difficult problems. Classic TRIZ is not well suited to the examination of complex situations composed of many problems, sub-problems and partial solutions, strongly interconnected. It has therefore been completed to give birth, among others, to the Inventive Design Methodology (IDM) framework. TRIZ and IDM share many similarities with Artificial Intelligence methods: they both propose to solve a problem by reformulation in an abstract model. Generic solving patterns are applied to this abstract model to produce abstract solutions. The domain-specific knowledge is then used to get the final solution concept. However, neither TRIZ nor IDM's descriptions are formal enough to permit a reliable software implementation and rely mainly on the experts' manual work. Therefore this paper proposes an ontological formalization of TRIZ and IDM to overcome these difficulties and allow the development of software tools to assist TRIZ/IDM experts in their work. © 2013 - IOS Press and the authors.
