    No full text
    The interactions between individual designers, within integrated product teams, and the nature of design tasks, all have a significant impact upon how well a design task can be performed, and hence the quality of the resultant product and the time in which it can be delivered. In this paper we describe an ongoing research project which aims to model integrated product teams through the use of multi-agent systems. We first describe the background and rationale for our work, and then present our initial computational model and results from the simulation of an integrated product team. The paper concludes with a discussion of how the model will evolve to improve the accuracy of the simulation

    Given the high potential of PV technology to reduce the environmental impact of electricity use of consumer products, it would be worthwhile to advance the application of PV systems in mass produced products. To date this field of application has been explored only to a limited extent. For this reason the developers of consumer products, the industrial designers, might be unaware of the possibilities of product-integrated PV systems [1][2]. Their focus on the utility of consumer products might have an added value to existing R&D of PV technology which emphasizes on increased performance and decreased production cost. In the nearby future integration of both points of view might be important to better integrate PV cells in consumer products. Therefore, in this paper, we will assess industrial product design of integrated PV technology in the context of future scenarios. In our project about 25 product designers have conceptually designed products with integrated flexible PV cells within a future scenario. By observing the resulting cases we can evaluate how the design process was established in the framework of integrated technology design, the product phase model and future scenarios. The PV-powered products that will be evaluated are an electronic book, an information bracelet, a floating platform, sports garment and a robotic monitoring device. Each product is supported by visual materials such as renderings and an explanation of the design process based on scenarios

    Integrated product relationships management : a model to enable concurrent product design and assembly sequence planning

    Get PDF
    The paper describes a novel approach to product relationships management in the context of concurrent engineering and product lifecycle management (PLM). Current industrial practices in product data management and manufacturing process management systems require better efficiency, flexibility, and sensitivity in managing product information at various levels of abstraction throughout its lifecycle. The aim of the proposed work is to manage vital yet complex and inherent product relationship information to enable concurrent product design and assembly sequence planning. Indeed, the definition of the product with its assembly sequence requires the management and the understanding of the numerous product relationships, ensuring consistency between the product and its components. This main objective stresses the relational design paradigm by focusing on product relationships along its lifecycle. This paper gives the detailed description of the background and models which highlight the need for a more efficient PLM approach. The proposed theoretical approach is then described in detail. A separate paper will focus on the implementation of the proposed approach in a PLM-based application, and an in-depth case study to evaluate the implementation of the novel approach will also be given

    Product ecodesign and materials: current status and future prospects

    Full text link
    The aim of this paper is to discuss the current status of ecodesign in the industry and its future implications for materials. There is today more and more focus on the environmental impacts of products during their whole life cycle. In particular, ecodesign aims at integrating environmental aspects during the product's design process as any other criterion, in order to reduce the life cycle impacts. Although a lot of product environmental impact assessment and Design for Environment tools already exist, environmental aspects are unfortunately rarely routinely integrated into product development process in the industry. This is mainly due to the fact that current ecodesign tools are little adapted to designers' practices, requirements and competencies. After the sequential and DfX paradigms, design of products is today maturing into Integrated Design, where multiple points of views and expertise have to be considered at the same time to progressively define the product

Design for assembly (DF A) is a recent approach towards improving product designs for easier and less costly assembly operations. The main objective of the research work is to develop an improved DFA system. The system is supposed to support new techniques for design for assembly and to provide users opportunity to assess and reduce the total production cost by means of reducing assembly time and cost at the early stage of the design process. The system is expected to enable designers to minimize the number of components of a product without compromising the product functions

    Cost Decision Support in Product Design

    Get PDF
    The constraints addressed in decision making during product design, process planning and production planning determine the admissible solution space for the manufacture of products. The solution space determines largely the costs that are incurred in the production process. In order to be able to make economically sound decisions, costing data support must be integrated into the decision making processes. Regarding product design, the designer must be supplied with transparent costing data, that is ready for direct application. In this paper a functional architecture for costing data support during product design, as well as a corresponding data structure are presented

    Novel Cooling Strategy for Electronic Packages: Directly Injected Cooling

    Get PDF
    This publication discusses domain integration of various engineering disciplines as an effective methodology to design new and innovative products. A case study illustrates how this approach is applied to the design process of a high performance electronic product. A novel and improved method for the cooling of electronic packages is presented. Standard package types, as for instance ball grid arrays, are equipped with directly injected cooling. The developed design is a very cost effective solution, as fewer productions steps and fewer procured parts are required compared to traditional cooling. The new design is also easily scalable, as multiple components on an electronic product can be cooled both uniformly and simultaneously. This allows for more overall design flexibility, which can result in a more integrated product design with advantages in terms of performance, volume, weight and production efficiency

    Design Opportunities in Service-Product Combined Systems

    This paper aims to examine recent research issues related to the integration of service and product in view of industrial design. Further, it attempts to identify new opportunities for further research regarding “product-servicization” vs. “service-productization”. In the continued efforts to provide the users with fuller experiences, one major trend is the blending of products and services. Much existing research seems to either present cases or propose frameworks regarding the ‘connection’, rather than ‘integration’ between products and services. Broadly, two major approaches seem to exist in this area: 1. product-servicization, 2. service-productization. The former generally indicates adding more services to existing products, whereas the latter generally refers to making services tangible and/or visible in the form of a product. However, findings of an extensive literature search conducted for this study suggest one important deficiency in dealing with service issues around the product: the ‘integration’ between the actual product design and service elements for supporting new service-product system. That is the rationale behind this research, an attempt to investigate the possibility for the integration of product design and service factors which could be embedded in the design of product itself in new service-product system. This paper is largely based on qualitative research. New design research opportunities are identified by qualitatively analyzing relevant literature, synthesizing the information and presenting some cases to support the main argument of the research. Design-led Service-Productization is not, and should not be re-arranging deck chairs on the Titanic. Rather, it should bring practical and tangible design issues related to new service-product system. Findings suggest that this approach could provide a new model of new product development integrated with a service scheme, which is a more proactive approach than “product-servicization”. Further development of this research could lead to establishing a framework for the Design-led Service-Product Integration.

    As a solution for traditional design process having many drawbacks in the manufacturing process, the integration of Product design-Process selection-Process planning is carried out in the early design phase. The technological, economic, and logistic parameters are taken into account simultaneously as well as manufacturing constraints being integrated into the product design. As a consequence, the most feasible alternative with regard to the product’s detailed design is extracted satisfying the product’s functional requirements. Subsequently, a couple of conceptual process plans are proposed relied on manufacturing processes being preliminarily selected in the conceptual design phase. Virtual manufacturing is employed under CAM software to simulate fabrication process of the potential process plans. Ultimately, the most suitable process plan for fabricating the part is recommended based upon a multi-criteria analysis as a resolution for decision making

    PLM and early stages collaboration in interactive design, a case study in the glass industry

    Get PDF
    Product design activity is traditionally presented as a succession of four to six stages. In the early stages of design, during the search for concepts, multi-disciplinary teams are working together, sometimes on the fringe of the digital design chain. But it is during these stages, that most of the product development cost is committed. Therefore, collaboration should be emphasized, and PLM software should contribute to it strongly. This paper first defines the boundaries of the early stages of design. Then, we analyze designer collaboration in this stage and describe the knowledge necessary for efficient collaboration. Finally, we propose and test a concept for a tool to assist the early stages of design, to be integrated in a continuum with other existing digital design tools. A case study is presented in Verallia, specialized in the design and manufacturing of glassware
