An expert system for developing walking-aided products is designed and a form database of components is constructed in this study. The design process for developing a product is computerized based on the concurrent design concept to reduce the lead time of product development and the waste in resource. To build the design expert system, the relationships between the requirements and the needed components are established by using the QFD (quality function deployment) method. The strong related parts in the QFD chart are transformed into expert rules and put into a tool named `Vp-Expert' to complete the expert system. On the other hand, the 3D geometric models of components in different forms are constructed based on the NURBS with the software `Alias' run on an SGI work station. The geometric models that are constructed based on a coding system and morphological analysis method are then saved as a form database which is to be used for constructing a basic model for a product. With the assistance of this expert system, the inferred suggestions presented with a coding system is obtained after the user/designer input the requirements for a product. The inferred codes are then used to construct a completely basic walker based on the previously constructed form database run on the Alias system. If new forms of the product are needed, the designer can modify the basic walker by moving the control points of the components to obtain a new set of configurations.
