Extension analysis and solution of contradictions in case adaptation

Abstract
Aiming at the design contradiction between the requirements and the structure in the case adaptation, an extension integration model of contradictory problems is established. And the corresponding solution method is given. Firstly, the extension integration model is constructed by analyzing the incompatible problems and antithetical problems in the case adaptation and separating the extension set of customer requirements, and the extension transformation theory is introduced into the case adaptation. Secondly, the extension integration model is solved by combining the extension strategy generation method and the transforming bridge method. And the obtained scheme is evaluated and selected based on the extension superiority evaluation; Then, store the adapted case into the case library. At the same time, the extension knowledge involved in the process of solving the contradictory problem is extracted and stored in the design knowledge base as a reference for subsequent design. Finally, taking the SK-15 vacuum pump as an example, the feasibility and effectiveness of the above method are verified. (C) 2021 The Authors. Published by Elsevier B.V.
