To build an expert system, especially in the mechanical design field, a knowledge base which contains a wealth of knowledge is an important issue for improving the efficiency of the design process. However, it is very difficult to build a knowledge base in mechanical design because there is a great deal of complicated knowledge in this field. In this work we derive an approach to build large knowledge bases in mechanical design by using an extended daemon function. Using this method, we believe it becomes possible to realize the characteristics of data base systems (DBS) in knowledge base systems (KBS). As a result, KBS will be suitable for managing and representing knowledge, and it will become easier to build a knowledge base in the mechanical design field.
