“…Cummings & Teng (2003), Larsson (2007). Within global design research, cross-culture collaboration and distributed teamwork has become the prime focus (Ma 2005;Ono 2006;Hansen & Ahmed-Kristensen 2011), which, in association with the multitude of literature arisen in the recent years, in turn, may reaffirm the findings of Littler et al (1995) that developing the product itself has not been the main objective.…”

A multitude of design guidelines that are intended to support design engineers with knowledge and information during the embodiment design of physical products have been developed back in the 1980s and 1990s. However, since then, the setting in which products are developed and designed has changed and associated tasks and activities are carried out globally rather than locally. Yet, knowledge on the benefit of such design guidelines and their impact on the performance of multinational design engineers from different regions and with different levels of experience is still lacking. To address this, a mobile eye tracking study has been developed and carried out with 47 differently experienced practitioners from Germany, Eastern Europe and Asia. The results show differences in how design engineers from different regions with different levels of experience may benefit from design guidelines and how design guidelines may impact experts’ and novices’ performance, indicate beneficial ways of using them and point out the kind of information and the way of representation that attracts the most attention within a design guideline. The paper concludes that the improvement and development of design guidelines that are intended to support the embodiment design of physical products is needed and proposes to rethink current engineering design guidelines both content-wise and representation-wise.

“…Feature association can be used to represent intent. An associative feature concept was proposed to represent relations between different forms of geometric entities depending on specific applications Ma andTong 2003, 2004). Associative features also model the evolvement of features at different stages of product development.…”

With widely used concurrent and collaborative engineering technologies, the validity and consistency of product information become important. In order to establish the state of the art, this paper reviews emerging concurrent and collaborative engineering approaches and emphasizes on the integration of different application systems across product life cycle management (PLM) stages. It is revealed that checking product information validity is difficult for the current computer-aided systems because engineering intent is at best partially represented in product models. It is also not easy to maintain the consistency among related product models because information associations are not established. The purpose of this review is to identify and analyze research issues with respect to information integration and sharing for future concurrent and collaborative engineering. A new paradigm of research from the angle of feature unification and association for product modeling and manufacturing is subsequently proposed.Keywords Concurrent and collaborative engineering · Feature-based design and manufacturing · Product life cycle modeling · Information validity and consistency

“…Many partial solutions to these problems were developed. [48]), sharing of non-geometric data, such as parameters, constraints, and features among different CAx systems, is still an unresolved problem due to the lack of a commonly accepted standard (Pratt et al [49]). As features are widely used in current CAx systems, and feature technology has the potential to overcome these problems, it is selected as the foundation of this research.…”

In the context of concurrent and collaborative engineering, the validity and consistency of product information become important. However, it is difficult for the current computer-aided systems to check the information validity because the engineers' intent is not fully represented in the product model. It is also not easy to check and maintain the consistency among related product models because information associations are not fully established. This research proposes and develops a feature-based product modeling scheme for the integration of computer-aided applications, especially CAD and CAPP integration. The scheme extends the traditional feature concept to a flexible and enriched data type, unified feature, which can be used to support the validity maintenance of product models. The novelty of this research is that the developed unified feature scheme is able to support data associations and propagation of modifications across product development life cycle stages. Therefore, it is a significant contribution to feature level interoperability in future virtual enterprises and collaborative engineering. In the proposed scheme, unified features provide an intermediate information layer to bridge the gap between engineering knowledge and product geometry. Unified features are also used to maintain geometric and non-geometric relations across product models. Major technical aspects of the developed scheme include: The identification of common properties and methods of different application features, and the definition of a generic, unified feature type that represents these common characteristics. A rule-based expert system is embedded into a feature-based product modeling system to handle non-geometric data and relations. A unified, multi-dimensional cellular model accommodates different geometric modeling requirements uniformly. Relations across the CAD and CAPP applications are identified and managed by a dependency network with a justification-based truth maintenance system. A database structure for sharing data and storing the inter-stage associations is developed. The feasibility of the proposed unified feature modeling scheme is demonstrated with a prototype system and three case studies which involve conceptual design, detailed design, and process planning.
