本文為機構設計專家系統之研究，主要宗旨在於將個人多年的電子產品之機構設計、電腦模擬、實務問題分析經驗，研究整理歸納出一些設計原則，產品設計知識主要由書籍之基本知?外，大多由資深工程師之經驗傳授，但隨著工程師?職或退休，使得公司之知?難以傳承，特別現在科技業都有大退潮，新進人員之專業知?將產生斷層現象。 有效的將設計經驗和知?有效的保存及?用，應將產品之設計知?作有效之知?化，因此建?一套完整之知?管?專家系統才可解決問題，並可使產品設計過程中，將工作上之瑣碎點滴，有系統、有邏輯地整理，從技術層次昇華至學術層次，提供予相關工作者，可快速培養新進機構設計工程人員，或是後續研究者之參考。 This paper is the research of the expert system for mechanism design, and purpose is to summarize some design principles with my many years of professional experience in mechanical design, computer simulation, and practical problem analysis for electronic product. Product design knowledge is mainly from books, and mostly through experience transmission and technology leadership by senior engineers. But the company’s knowledge is difficult to inherit when engineers leave or retire. Especially now the technology industry has a lot of leaving, the new staff will happen technology or knowledge faulting phenomenon.Effective preservation and use of design experience and knowledge, we should design products for effective knowledge of knowledge. Hence, the establishment of a complete set of knowledge management expert system can solve the problems, and systematic and logically organize the work of the trivial matters in the product design process. From the technical level to the academic level, and provided to the relevant workers, can quickly develop new institutional design engineering staff, or let researchers reference use in the future.
