The development of a collaborative design chain reference model for the motorcycle industry

A well-defined and flexible design chain reference model forms the basis for promoting collaborative design chain. The Special Interest Group under the Design Chain Council proposed the design chain operations reference (DCOR) in an attempt to assist enterprises building a design chain modeling frameworks. To date, DCOR version 1.0 only provides preliminary definitions, such as those for major design procedures, and lacks an example of best practices in the industry. Additionally, few studies have attempted this research issue. This study integrates the concepts of design chain, collaborative product design, and collaborative product commerce in a proposed collaborative design chain operations reference model (CDCORM) based on DCOR as a reference for developing a collaborative design chain system in the product lifecycle. The CDCORM consists of four hierarchical levels: collaborative design chain business model; collaborative design chain cooperative model; collaborative design-chain process model; and, a collaborative design chain operational model. Based on project management, the CDCORM has five core procedures-product plan, concept design, detail design, design review, and design amend. This study also assesses the effectiveness of the CDCORM by applying it to the motorcycle industry. In summary, this study extends the DCOR model and proposes a complete collaborative design chain reference model and implements a system in the motorcycle industry as a case study. This case study serves as a best practices example for the motorcycle industry.

An Internet-based integrated product design environment. Part II: its applications to concurrent engineering design

Concurrent or collaborative engineering (CE) has inspired research in the area of design decomposition, which facilitates the concurrency of product lifecycle functions from the earlier stage of the product development process and reduces the complexity of a design problem. The decomposition-based design, on the other hand, necessitates various integration efforts for recombining the decomposed design problems. This is the second of a two-part paper proposing a multi-agent system (MAS) framework for integrated product design in a computer network-oriented CE environment. Part II discusses the applications of the proposed MAS framework to concurrent engineering design. The proposed framework realises the systematic and timely design integrations between multi-functional/cross-functional team members in a dynamic design environment, by enabling model integration, solution integration and tool integration. The proposed design agents make the problem-specific engineering models or heterogeneous design tools interoperable and network-accessible, and also provide the interaction spaces for communicating, integrating or coordinating the individual design solutions. Throughout the paper, the proposed system is illustrated with a successful implementation of a continuously variable transmission (CVT) design problem over the Internet .     

A Study on Development of a Die Design System for Diecasting

Diecasting is one of the forming methods for manufacturing a large number of products with short lead time and a good surface by high injection pressure of cast alloy. Die design is composed of selection of cast alloy, design of product, runner and gate design, etc. In reality, however, die design for diecasting has been performed by a trial and error method, which causes economic and time loss. This paper describes the development of the computer-aided design of product and die design. The CAD system has been written in AutoLISP on the AutoCAD with a personal computer. In this study, the die design system for the die casting process has been developed and a flowchart is presented for the automation of die design, especially of the runner–gate system. As the generation process and die design system using 3D geometry handling are integrated with the technology of process planning, die design can be automated. In addition, specific rules and equations for the runner–gate system have been presented to avoid too much trial and error with expensive equipment. It is thus possible for engineers to make automatic and efficient die design for diecasting which will result in a reduction of the required cost and time. An example of a cap-shaped product, i.e. a motor pulley, is given using the proposed flowchart.
