Abstract: In conceptual mechanical design process, designers sometimes focus their attentions on mapping a sub-function or functional unit to a single mechanism or system, and ignore the interfaces among the structural elements. This paper first summarized the behavioral characteristic of the interfaces in energy, mechanics, kinematics by analyzing the roles, classification and connection styles of such interfaces. Subsequently, it introduced the concepts of function and free surface, and gave the interface design process. Finally, a case study was conducted to demonstrate the feasibility of the proposed methodologies.

Abstract: A process model FPBS for conceptual design is put forward. The function and behavior etc about the model are defined and analyzed, and the expressions are analyzed too. The relationships of elements, the application of model are discussed and analyzed. The model can be effective used to guide conceptual design and applied to construct computer aided conceptual design system.

Abstract: So far the research of product intelligent design model focused on product function. Referring to the three principles, generality, practicability and reusability we stress that modeling for behavior meets more requirement of intelligent design model. Corresponding to product behavior we suggest the concept of behavior flow. Based on the concept we suggest the framework of product intelligent design model and adopt hybrid Petri net to describe and formulize the model of behavior flow. At last according to such theory we build a model for engine behavior to demonstrate the suggestions and methods.

Abstract: An effort is made to give a description of a computer-aided conceptual design system. A novel Function-Action-Behavior-Mechanism (FABM) modeling framework is proposed to realize mapping from the overall function to principle solution according to customer’s requirements. Expansion and modification rules in the demand behavior are developed to extend the innovation of principle solution. A case study on pan mechanism design for cooking robot is presented to show the procedure of how to implement the intelligent reasoning based on the FABM model.

Abstract: Consistency maintenance is a key problem in collaborative product design. Firstly, based on product design theory, the semantics relationships described by XML among components in collaborative product design system are made. Secondly, the associated components are determined through backward and forward semantics reasoning. Finally, the data is updated by constraints solving, and the consistency maintenance is achieved.
