Computer supported collaborative work (CSCW) technology is used to solve the resource-sharing problems in collaborative design, analysis, and manufacture. To address this need, a system called CollabVue for collaborative product design between designers and manufacturers is proposed in this study. This paper first introduces the framework of tolerance analysis system based on CollabVue, and then discusses the utilization of geometric topology information in 3D model to resolve the problem of dimension information input and the related specific operations. Based on object-oriented technology, a new data structure to interactively pick up and store dimension information is established. Finally the model uses iterative method to compute technological dimension chain equation.

Collaboration Process

Collaborative groups, by their very nature, involve the interactions of many participants which can vary in time, place, culture, knowledge, and ability. The design of collaborative technology for work groups must occur in conjunction with the users while avoiding the dangers of technology-centered product development. This paper focuses on applying a group-centered approach to the development of Computer-Supported Collaborative Work (CSCW) products. This approach emphasizes the importance of team members” participation in the design process such that the resulting technology is centered around the users” needs and capabilities. By allowing collaborative groups to elaborate on real issues related to their actual work context, and to suggest specific ways to improve their work, a group-centered approach to the design of CSCW systems can be realized. The utilization of the Advanced Knowledge And Design Acquisition Methodology (AKADAM), consisting of concept mapping and design storyboarding techniques, was suggested as a basis for achieving this level of team participation. The concept mapping technique elicited insights into the collaboration process, identified problem areas, and generated suggestions for improving group work. With the aid of the design storyboarding technique, these suggestions for improvement can be directly translated into CSCW tools.

Computer Supported Collaborative Design(CSCD) is the applicarion of Computer Supported Collaborative Work(CSCW) in the product design field. Based on the analyse of the key technologies and problems of CSCD, a CSCD design frame faced to product design is established. Then a CSCD system faced to radar key components is founded with Pro/INTRALINK software and re-exploiting technology. Some key processes are designed too, such as database management, workflow programming, information communication, file release, conflict identification and safety management. These will provide a reference for constructing a cooperative design environment.

User requirements play an important role in product design activities. Customer satisfaction has a direct bearing on the acquisition of user requirements for product design. However, these implicit requirements are equipped with the attributes of potentiality, fuzziness, and subjectivity. In this paper, a new implicit user requirement processing method based on a cloud service platform is proposed to resolve the difficulty of acquiring implicit requirements. Initially, this method collects user requirement data via a metaphor extraction technique using a cloud service platform. Then, the requirement data are clustered and mapped with product attributes. Finally, the mapping results are visualized to intuitively instruct product design and optimization. Overall, the method is a user-centered innovation paradigm implemented on a cloud service platform to realize collaborative design and resource sharing. Finally, an application case is presented to illustrate the method, and the results indicate that the method is effective and could serve as a reference for product design.

Abstract This paper presents an approach to support computer-aided conceptual design of mechatronic assemblies in a collaborative, multi-user environment. We describe a system, Conceptual Understanding and Prototyping (CUP), that allows a team of design engineers, collaborating over the Internet, to develop a high-level structure-function-behavior (S-B-F) description of an assembly in a VRML-based virtual environment. Our goal is to enable users to navigate intricate product data management (PDM) and case-based design knowledge-bases, providing the ability to perform design at conceptual level and have intelligent CAD tools that can draw on details from large repositories of previously archived designs. This work furthers research efforts in computer support for collaborative design activities — drawing on work in Human-Computer Interaction (HCI) and Computer Supported Collaborative Work (CSCW). We envision CUP to be a network interface to next-generation of engineering PDM systems and CAD databases. We are deploying CUP as query interface to the National Design Repository (http://repos.mcs.drexel.edu). This will enable CAD users to interrogate large quantities of legacy data and identify artifacts with structural and functional similarities — allowing designers to perform case-based and variant design.

Design education is important at technical universities and colleges. In general, real product design requires collaborative work. In this chapter, the authors discuss collaborative design education. An A360 cloud platform on Autodesk's 3D computer-aided design “AutoCAD” is adopted to illustrate a collaborative design activity implemented in the Engineering Graphics class offered at the College of Science and Technology, Royal University of Bhutan. By using A360 cloud, students can share a 3D model with group members. Based on feedback received, students can modify the initial model, share it, print, and discuss the modified object with members. This collaborative work allows students to create enhanced 3D design objects while engaged in discussions and interactions. The authors also discuss some difficulties encountered during the collaborative process and offer recommendations and future research ideas.

Research on the use of iPad in initial teacher education is limited. This paper outlines a study to examine how the professional learning and pedagogical knowledge development of student teachers could be supported following 1:1 iPad deployment on a second level initial teacher education programme in Ireland. Findings show that iPad can be utilised both as an effective pedagogical tool and as a medium for the creation of new learning spaces where student teachers' professional and pedagogical knowledge development is supported through feedback, peer-learning, resource sharing and critical reflection. Creating resources with and for iPad as part of a collaborative design process can also support student teachers in developing and integrating technological, pedagogical and content knowledge (TPACK) within their approaches to teaching, learning and assessment. Implications for initial teacher education providers and the integration of technology within schools are outlined.

Remote User

For collaboration among users, sharing audio-visual, textual, graphical, or even interface-related information is the essence of computer-supported collaborative work (CSCW). Since most applications that are being used in private and work life these days are merely usable on the computer on which they are executed, collaboratively working with a single application is the most challenging part of CSCW. This is not only true because these applications are unaware that they are executed in a distributed environment, but, in particular, because of the numerous possibilities of data to be shared among the distributed users. Thus, the distribution of the application’s functionality over the network must be added transparently and, more important, subsequently without changing the application’s semantic. The effect has to be created at each remote site that the application is running locally and, therefore, can also be controlled by any remote user with a more or less immediate effect to the application. This problem is referred to as application sharing in the remainder of this article.
