    Problem definition and identification of contradictions in the interdisciplinary areas of mechatronic engineering

    The modern TRIZ is today considered as the most organized and comprehensive methodology for knowledge-driven invention and innovation. When applying TRIZ for inventive problem solving, the quality of obtained solutions strongly depends on the level of completeness of the problem analysis and the abilities of designers to identify the main technical and physical contradictions in the inventive situation. These tasks are more complex and hence more time consuming in the case of interdisciplinary systems. Considering a mechatronic product as a system resulting from the integration of different technologies, the problem definition reveals two kinds of contradictions: 1) the mono-disciplinary contradictions within a homogenous sub-system, e.g., only mechanical or only electrical; 2) the interdisciplinary contradictions resulting from the interaction of the mechatronic sub-systems (mechanics, electrics, control and software). This paper presents a TRIZ-based approach for a fast and systematic problem definition and contradiction identification, which could be useful both for engineers and students facing mechatronic problems. It also proposes some useful problem formulation tech-niques such as the System Circle Diagram, the enhancement of System Operator with the Evolution Patterns, the extension of MATChEM-IB operator with Infor-mation field and Human Interactions, as well as the Cause-Effect-Matrix

    Part 5: TRIZ and Knowledge ManagementInternational audienceKnowledge is an important driving force for creative design. The knowledge fusion, which is formulated by knowledge from different backgrounds, is able to inspire novelty solutions to engineering design. In this paper, a design method is proposed to facilitate knowledge fusion in engineering design based on the theory of inventive problem solving (TRIZ). In order to formulate this method, the mechanism that fosters creative ideas through knowledge fusion is firstly explained, subsequently, approaches that transform the design problems in each of the above-mentioned design stages into TRIZ problems are discussed, since the standard problems in TRIZ can be solved by corresponding TRIZ methods. A design process is therefore formulated by integrating formerly discussed strategies. Moreover, its workability is verified by a case study. The advantages of the proposed method such as the expanding the searchable range of knowledge resource for TRIZ problem solving are discussed in the final section
