According to the diversity, dynamic and correlation of product design knowledge; this paper put forward a knowledge representation method for product design based on ontology. Established a knowledge unit with the core of concepts set, property set, knowledge set and function set, introduced input and output module, to realize the information transmission between knowledge units, and also lays a foundation for knowledge networks construction, intelligent and agile design. Finally, this paper take cylindrical spiral spring design for example, verified the effectiveness of this method.

Based on product design process knowledge reuse, according to the characteristics of ontology knowledge representation, process ontology knowledge representation method is offered. The paper extracts the category of design process, defines and describes the attribute and relationship of these categories. Then, the design process ontology database based on process ontology is constructed. As a result, it supports to achieve the sharing and reusing of design process knowledge.

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.

Definition Of

In this paper, we investigated the definition of product design knowledge, design knowledge origin characteristics and design knowledge formalized representation method, etc. We also established the methods to classify and represent the concept-design knowledge and developed an ontology-based model presenting the design knowledge as well as a model for modeling cycles. From the design knowledge management’s angle, design knowledge modeling approach is studied to support the design knowledge development, transfer and reuse for the construction machinery the knowledge modeling.

Representation Method

Many manmade systems, from tea clippers to banking database management tools, exhibit an important common feature that a useful impulse is produced and functionates in them, being affected by favorable or unfavorable circumstances. While some of these systems are highly formalized, others remain operated or investigated quite intuitively. Their structural similarity urges one to think of conveying of experience of formalization from most to least formalized systems, but this process itself needs formal grounds to avoid the errors of inadequate formalization. In this chapter, a solution in the dynamic knowledge representation method and underlying theory of multitudes are sought.

One in every seven Americans has some form of disability. The number of people with disabilities is expected to increase, perhaps significantly, over the foreseeable future. Nevertheless, persons with a disability remain underserved by consumer products. Product designers fail to design universal products primarily due to a lack of knowledge, tools, and experience with universal design. Though challenges to complete access remain, the design of universal architectural systems reflects a better codification of methods, guidelines, and knowledge than available to universal product design. This article reports research efforts to transfer elements of the design knowledge and tools from universal architectural design to universal product design. The research uses the International Classification of Functioning, Disability, and Health to formally describe user function, the Functional Basis to describe product function, and actionfunction diagrams as an analytical framework to explore the interaction between user activity, limitation, and product realization. The comparison of the universal and typical architectural systems reveal relevant design differences in specific parametric realization, morphology, and function. Of these differences, parametric was the most common with functional the least common. The user activities that most frequently result in a design change are reaching followed by maintaining body position. The comparison of architectural systems to consumer products noted a common trend of a functional design change made in result to the user activity of transferring oneself.
