Research On Knowledge-base Transmission Scheme Design System

The paper studied the role of abstract concept and relative abstract concept in product design. Combing with concept design in mechanical transmission product design, the relations among user's requirement, product's function and structure were discussed. A method that user's new requirement is based on the product which has the basic function was put forward. With the available design schemes, combining cell function answers , the answer that satisfy user's requirement can be achieved . Making use of new material and new technology can change the scope of the cell function answer , creative design can also be achieved. Study was given on how to achieve the match of cell function answers. Multi-layer filtrate method was used to avoid combination explosion . Multi-level method and multi-level fuzzy evaluation was used to evaluate the answers and the best answer given. In the process of system's construction , design knowledge was effectively assembled. The interface to exchange information with other system is designed. The system was constructed with object- oriented technology to guarantee the construction ,feasible and expansion. User interface is simple and friendly designed.
