Divide And Rule

In order to deal with complex product design optimization problems with both discrete and continuous variables, mix-variable collaborative design optimization algorithm is put forward based on collaborative optimization, which is an efficient way to solve mix-variable design optimization problems. On the rule of “divide and rule”, the algorithm decouples the problem into some relatively simple subsystems. Then by using collaborative mechanism, the optimal solution is obtained. Finally, the result of a case shows the feasibility and effectiveness of the new algorithm.

Abstract Based on knowledge representation in product design, we propose a knowledge model of the product design process based on graphical semantic perception. The ontology semantic of the product is analyzed together with the product design process knowledge. Then the basic element model for knowledge representation of the product design process is built. With the concepts of the extension origin point basic element and extension vector thus defined, knowledge representation, consisting of growth, convergence and optimization is realized. On this basis, the model for case base clustering based on graphical semantics is built. Feasibility verification is performed with the case of appearance design of a machine tool. The highlight of the proposed method lies in the combination of the formalized and quantitative approach for product appearance design.

Rapid Modeling

Product conceptual design derives from the functional requirement initially, and the overall structure control for product design is one of the most difficult problems being addressed in CAD modeling. The objective of this investigation is to present a framework on rapid modeling using rules and mechanism library for mapping between functions and mechanism structures. In this paper, it is shown that the overall structure can be achieved largely by using multi-level parametric skeleton model. In order to drive the conceptual design into a more detailed design, the intelligent master model is presented to realize the parametric feature modeling and design knowledge reuse. The main contribution of this paper is that an integrated framework has been developed to design assembling tools of satellite by using a necessary auxiliary wizard. The case studies presented demonstrate the potential significance of this work for a wide range of engineering design problems.
