First, the design knowledge is discussed, and a unified design knowledge model is proposed. Following that, we identify three design knowledge reuse patterns which contribute to the understanding of how designers reuse knowledge during the design process. Based on that, we propose a design knowledge reuse model. This model can provide design knowledge according to the design knowledge reuse patterns. The model also provides the ability to update itself according to the captured actions of the knowledge users. At last, the method is validated with a research cooperator on the hydropneumatic spring component. 1. Introduction A large number of researchers appeal that the active utilization of a company¡¯s knowledge is vital to maintaining competitive advantage in today¡¯s knowledge-based economy, particularly within design and manufacturing environments [1¨C3]. The reuse of existing design knowledge benefits both new design and redesign. For a new design, the designer has great freedom in choosing the structure or deciding the value of the parameters, while, for a redesign process, a designer may concentrate his/her attention on the design defects and problems occurring in the existing design and the customers¡¯ new needs of the existing product. However, the levels of knowledge reuse in manufacturing companies are significantly low [4]. To promote the level of design knowledge reuse, many research works are carried out. At the beginning, researches on design knowledge management focus on content search by matching keyword and file name. However, many shortcomings are realized by researchers as stated by [5]. The most important drawback is that design knowledge is often incomplete or is not adequately defined at a detailed level for current information search methods. Consistent with that an integrated design knowledge model should benefit the knowledge reuse, many design knowledge reuse models are proposed and studied, like process-based knowledge reuse model [6], functions based knowledge reuse [1], ontological knowledge reuse model [7], and CAD/CAE based knowledge reuse which is widely known as knowledge-based engineering (KBE). Many techniques from artificial intelligence (AI), like case-based reasoning (CBR) and Bayesian network, are adopted to solve the problem of design knowledge reuse [2, 4]. In recent research literature, many researchers point out that further effort is required to understand the needs of %U http://www.hindawi.com/journals/isrn.industrial.engineering/2013/928013/
