3D models have been playing an important role in product design and manufacturing process in modern enterprises. MBD (Model-based Definition) technology enables 3D models to include various manufacturing information, which results in eliminating 2D engineering drawings. Full Tree-dimensional technology must be the developing trend of future enterprises. At the present, 3D models, however, only include...
Although there have been numerous design rationale research projects, few of them has received wider adoption. Because current design rationale systems are not demonstrated the value of the approach in practice due to lack of the design rationale knowledge evaluation. In this paper, we present a new design rationale knowledge evaluation method which is to measure the design rationale knowledge comprehensive...
Because the 3D model is closer to the real product, 3D Model-based design not only speeds up the product design process, but also improves the readability of product information. 3D Model-based Design will be a trend of the development. It is necessary to add all kinds of product information, including design knowledge, into 3D models to enrich 3D models. In this paper we give the background of 3D...
Because design is an iterative and evolving process, recording and representing designer's thinking process plays an important role for design change and reuse. After giving a brief review of the previous related research, a design thinking process model is created for representing the design thinking process. Its knowledge structure consisting of design intent, design decision, design rationale and...
One way to reduce potentially serious problems caused by modifications to the original design is to find out design thinking process of the original designer. The knowledge structure of design thinking process is represented, which is composed of design intent, design decision, design rationale and design operation. Semi-formal structure is adopted by the presentation, which means both the expressiveness...
