Abstract This paper presents a summary of research into the development and implementation of a domain independent, computer-based model for the conceptual design of complex mechanical systems (Ouellette, 1992). The creation of such a design model includes the integration of four major concepts: (1) The use of a graphical display for visualizing the conceptual design attributes; (2) The proper representation of the complex data and diverse knowledge required to design the system; (3) The integration of quality design methods into the conceptual design; and (4) The modeling of the conceptual design process as a mapping between functions and forms. Using the design of an automobile as a case study, a design environment was created which consisted of a distributed problem solving paradigm and a parametric graphical display. The requirements of the design problem with respect to data representation and design processing were evaluated and a process model was specified. The resulting vehicle design system consists of a tight integration between a blackboard system and a parametric design system. The completed system allows a designer to view graphical representations of the candidate conceptual designs that the blackboard system generates.

Holographic Display

In the research reported in this paper, we investigated if a holographic display based truly 3D virtual design environment can effectively support 3D conceptual design. In this investigation, we applied heuristic evaluation method (Nielsen and Mack, 1994), but with some differences. We first conducted a literature study and compiled a comprehensive list of conceptual design tasks. We then asked selected experts to evaluate the experimental system and to indicate which conceptual design tasks can be supported. The experimental 3D design support environment consisted of a holographic display as a primary visualization device. In this experimental system, visual representation of information is presented aerially by using the holographic display, and viewers can interact with the displayed images by using the traditional input devices such as mouse and keyboard. The study established that this system can support only a handful of conceptual design tasks, in particular those requiring passive visualization such as review of the ergonomics of the product and aesthetics review. Other conceptual design tasks can be supported either partially or are not supported at all. This can be attributed in part to the shortcomings of the display, which include, for instance, poor resolution, inability of viewers to experience stereoscopic view all around the virtual object, lack of mechanism for enabling direct interaction between the viewer and the displayed virtual object, and lack of proper input mechanisms and user interfaces.

The Common

For modeling and simulation of dynamic systems, bond graph methods could be served as a powerful tool to make a compete model and to test the performance of the model. Bond graph is an explicit graphical tool for capturing the common energy structure of systems. This paper deals with the conceptual design of an electrical-magnetic pump, which should be considered as the different domains design, such as hydraulic, electrical magnetic and thermal domain. After the realization of the basic pump functions, the model will be converted into a 20-sim design environment in which the configuration parameters of the pump can be adopted in order to optimize the choice of the better pump properties, such as efficiency, capacity and the power consumptions. It is seen that the bond graph method with the 20-sim software can solve the pump design problems effectively.
