“…However, due to the limitations of legacy systems and software, large amounts of manufacturing data used in iterative design processes are not available for concurrent or shared use, being typically separated into geometric and non-geometric data with the aim of managing these data in parts (Peng and Trappey, 1996). Anumba (1996) believes that it will take some time before fully-integrated design applications for each phase of the design process are made available.…”

“…However, although most CAD systems are capable at running intricate geometric details of a product throughout its life cycle, not all CAD systems can communicate with each other in a network setting (Chao and Wang, 2001). If engineers only store records in a CAD¯le format, information and drafts will be organised independently and associated data cannot be concomitantly changed in the database, causing the management of engineering data to be ine±cient (Peng and Trappey, 1996). Therefore, the following hypothesis is proposed:…”

“…It is understandable when the variable CAD use for engineering design was removed because CAD use in this context converges more towards design rather than knowledge or information sharing. Also, due to the limitations of long-established software, large amounts of manufacturing data in iterative design processes fail to be shared by users (Peng and Trappey, 1996). This suggestion can also cause CAD use in engineering design to be more rigid as far as knowledge sharing is concerned in this¯rm.…”

As a complex method for manufacturing and development, concurrent engineering has been studied and implemented extensively in the manufacturing industry to speed up production schedules and to reduce costs. One of the tools used in concurrent engineering is computer-aided design or CAD in short. CAD applications in multifunctional knowledge distribution refer to the use of CAD to provide information to di®erent groups of employees in their organisation to sustain new product development activities. Similarly, the move towards knowledgebased competition ampli¯es the importance of bridging actions in addition to tactical coalitions where key role of institutional knowledge, system improvement and knowledge sharing are focussed on. However, very few studies have been conducted on the use of CAD and knowledge management in in°uencing concurrent engineering project performance in Malaysian man-ufacturing¯rms. Hence, this study focusses on determining the nature of the relationship between CAD use and knowledge management with concurrent engineering project performance in a Malaysian manufacturing¯rm. A survey was conducted within the¯rm, yielding a total of 226 usable responses that were then analysed using SPSS. The¯ndings indicate that there is a sig-ni¯cant positive relationship between CAD use and knowledge management and concurrent engineering project performance. In addition, CAD use for cross-functional information sharing together with the three knowledge management processesinternalisation, combination and externalisation can explain 55.3% of the variance in concurrent engineering project performance. An interesting¯nding of this study based on the multiple regression analysis conducted is that the use of CAD for engineering design and socialisation are not signi¯cant in in°uencing concurrent engineering project performance. In practice, this¯nding is relevant because when coupled with CAD use, knowledge management approaches that are more externalisation, combination and internalisation-orientated are often practiced if compared to socialisation-orientated activities.

“…for coil springs -tendency to amplify sound vibrations arising from coil impacts -low corrosion protection -high weights -relevant overall dimensions -reduced fatigue strength for stabilizer bars -strong constraints around the rotation fulcrum -compliance of the journal box due to material dishomogeneity -slipping between bar and journal box give rise to noise starting -using metal in journal box increases the overall system weight -goal of ecological product is hampered by material dishomogeneity -production process appears as complex and expensive -high weight of solid bars Solutions to overcome actual limits have been then proposed and analyzed considering a cost-quality-safetyenvironmental overall perspective [6][7][8][9], that are: for coil springs -new form able to reduce weights and dimensions, also avoiding impacts between end coils -thermoplastic coating which allows for both noise damping and corrosion protection -new materials, i.e. titanium alloy, to improve performances -redesigned processes for heat treating to pursue higher fatigue strength for stabilizer bars -tubular materials for bars -thermoplastic materials for all the journal box Product design patents have been already applied for both the form and thermoplastic coating of coil springs and for the entire thermoplastic journal box.…”

The paper presents results of a pilot project on technological innovation of main flexible components for automotive suspension systems, that are coil springs and stabilizer bars. Current technology has been described and related problems have been outlined. In order to fulfil features as compactness, lightness and environmentally conscious design, solutions based on new forms, materials and manufacturing processes have been proposed. Improvements in weights, dimensions, noiselessness, corrosion and fatigue strength, environmental effects, have been all assessed, keeping a quite low project cost (around $ 3 million).

“…The third stage from 1990s to 2010s takes the integration, distribution and collaboration of different design tools as main feature [48][49][50][51][52][53][54][55][56][57][58][59][60]. On one hand, a lot of design programs greatly expand their functions based on improvement of existing functions, on other hand, design data produced by these programs can be well organized by PLM, PDM or other platforms.…”

Abstract-As one solution to complex product design, the integrated design environment has experienced several decades of development with great changes. This paper reviews the emergence, development history and future trend of integrated design environment. Firstly, the concept and connotation of design are analyzed, and then from the development of design behavior and the development of computer aided design, the inevitability and development history of integrated design environment are elaborated. Secondly, the background and characteristic of different kinds of integrated design environment were analyzed and elaborated. Finally, based on the trend analysis of the integrated design environment, future research direction and goals are proposed. Through this review, basic materials and direction for the related academic research can be provided.
