| Summary: | 碩士 === 中原大學 === 機械工程研究所 === 97 === Due to the development of the 3C industry and the diversification multiple functions of products, the life cycles of products have gradually become shorter and shorter. In order to meet the demands and needs of various clients, products are required to be constantly renewed and updated, and design modifications have become an inevitable and crucial procedure. Effective design modifications not only speed up product development and save the cost, but it also enhances the efficiency of products, thus satisfying the needs of clients. This study is mainly divided into two parts. The first part is applying the CAD software Pro/ENGINEER browser to develop a navigating system for design change of 3D mold design with knowledge management. Through the procedures of navigated system and the knowledge based functions, errors made by users when operating the software can be reduced. Also, through the navigation of the system, parts that need to be modified will not be left out, therefore, design modifications can be completed quickly and the efficiency design modifications can be enhanced. Nevertheless, by integrating programming and databases, design modification forms will not have to be printed out and shown on paper. In addition, by cooperating with online messenger, each and every related department are notified of the conditions that occurred in design modification, thus synchronizing information and reducing the occurrence of errors. Integrated with design modification knowledge bases, the design modification information of this time is thus recorded, as a result, providing reference knowledge for design modifications in the future.
The second part is the knowledge base design modification database. The main purpose is to allow users to refer to past design modification cases so that when the chief is verifying and examining design modification applications, the chief is able to accurately determine, according to the information provided by the database, whether there is the need for design modification or not. Moreover, according to the information provided by the database, design modification can be carried out with the cooperation of design modification navigating system to provide reference to users and to speed up product development process. In addition, places that need to be kept an eye on are added into navigating procedures so as to reduce the number of times design modification occurs and also to shorten product development time.
