In this paper, proposed through the development process of a VCR the process of making exact three-dimensional modeling data using the Alias-one of the popular workstation in product design development process. At first, the features of the NURBS curve which is the basic curve in the modeling of Alias system and the methods of building surface are reviewed. The methods of rendering, lighting and textures are reviewed for application of realistic image presentation after building basic surfaces. The synthetic application methode of these factors necessary for the product design modeling is presented through the development process of a VCR.

This study suggests the output of the fingerprint doorlock design development through the structured methodology of concept selection in the process of design development, after characterizing the doorlock product itself. All of the early phases of product development are very important on eventual product success. Concept selection is the process of evaluating concepts with respect to customer needs and other criteria, comparing the relative strength and weaknesses of the concepts, and selecting one or more concepts for further investigation or development. To obtain the ideal concept o( new product, this work used a two-stage concept selection methodology which consist of concept screening and concept scoring. As a result, this study represents the fixed design rendering for mass production.

Concurrent Engineering(CE) has presented new possibilities for successful product development by incorporating various product life-cycle functions from the earlier stage of design. In the product design, geometric representation is vital not only in its traditional role as a means of communicating design information but also in its role as a means of externalizing designer's thought process by visualizing the design product. During the last dozens of years, there has been extraordinary development of computer-aided tools intended to generate, present or communicate 3D models. However, there has not been comparable progress in the development of 3D-CAD systems intended to represent and manipulate a variety of product life-cycle information in a consistent manner. This paper proposes a novel concept, Minus Volume (MV), to incorporate various design information relevant to product lift-cycle functions. MV is a functional shape that is extracted from a design object within a bounding box. A prototype 3D-CAD system is implemented based on the MV concept and illustrated with the successful implementation of concurrent design and manufacturing.

Purpose - In the past, designs for traditional products have usually focused on historic techniques. However, this tradition of using historic techniques has now been replaced by the trend of using the innovative design concept. Research design, data, and methodology - To measure future market trends and quality requirements, we apply the results of the questionnaires and analyze them with various experimental processes and a design methodology. In this way, we gauge the impact of the innovative product value chain on the promotion of new products. Results - Accompanied with an innovative product value chain, the product can stimulate the development of enterprise management, which has become the main issue in social and economic development in every developed country, and can facilitate the progress of enterprise management throughout the enterprise. Conclusions - Customer demand should be emphasized as the primary means to solve design problems, to design optimal solutions, to create differentiation with competitors, and to pursue optimal marketing strategies.

This study presents the process of fashion item development with velvet through creative thinking methods. Creativity is one of the most important requirements for a successful job career and education enhancing creative thinking is needed in the area of fabrication, product design, and marketing strategy development. Velvet was selected as a research stimulus because it is a luxurious fabric with various differential properties such as a soft touch, unique luster, excellent drapability, and fine physical properties. The research methodology included creative thinking methods review, the selection of the tools, idea sourcing and listing, sequential idea evaluation and sample product making. After review of the various creative thinking methods, a combination method and forced connection method were employed as research tools to confirm the usefulness of creative thinking training because of their independence of use and application simplicity. A total of 12 university students participated as subjects in this research. After some training, each student derived ten ideas for velvet products that utilized a combination method and forced connection method. A total of 120 ideas were evaluated for novelty, technical possibility, practicality, and marketability; subsequently, 24 ideas were adopted and developed as sample products. The effectiveness of creativity education in fabrication and product design classes was verified through the whole process of product planning.

The purpose of this study is to develop design guidelines for developing innovative products utilizing the characteristics of creative consumers(cresumers) who create alternative usages of consumer products, and to suggest effective way of applying the guidelines in design process. To do this, the study conducted the analysis on the characteristics and types of cresumers and in-depth interviews and observations of actual cresumers. The study was able to initially come up with 131 items in 7 categories through keywordization and affinity analysis of prior outcomes, and reorganized and modified those to 52 items in 4 categories. After verification of co-relationship and credibility analysis with 2 evaluation sessions (7-scale SD), the study has reached 4 categories - product concept development, product development, product use environment, and market possibility - with 46 guideline items. The study developed a design toolkit to effectively apply the guidelines in the product development process. The toolkit consists of three chapters and provides explanations and related examples to clarify the categories and individual guidelines, designed in the form of cards and booklet.

In the previous research, the authors proposed a novel concept called Minus Volume (MV) to incorporate various design information relevant to product life-cycle functions. This paper proposes the use of the MV concept for the collaborative design environment, where many team members are geographically distributed over the networked environment, including Internet, Intranet, WWW, etc. A prototype 3D-CAD system is implemented based on the MV concept and illustrated with the successful implementation of collaborative design example.

The development of Korean textile industry has continued for the early industrialization. But a change in situation of circumstances, textile industry undergoes hard times. To overcome the barrier, therefore, technical development and design innovation are needed to make high value added product. This paper try to put to practical use of the silk weighting process technique(WPT). First, we investigate the technical trend of WPT to summarize the theory, and examine the feasibility of technical development. Second, the application of Graft process to silk textile is examined to know whether it is possible as an practical use. Next, we present the practical way of WPT using MAA monomer through experiment. The results are as follow. 1) Considering the lack of silk yarn. Graft process is appropriate new technique to make the value added product, and fine quality. 2) Studing textile goods, it need inter-displlinary co-work not only fiber engineering scope because textile goods is closely related with fashion industry. 3) MAA monomer used in this paper is more excellent then other monomer because it has good weighting effect and does not harm to the nature of textile. 4) MAA WPT is good for silk textiles of ladies jacket and neck-tie.

Currently the systematic approaches to implementing CALS and reducing time-to-market are widely used, which is based on the concept of PDM. The concept of PDM is to maximize the time-to-market benefits of concurrent engineering while maintaining control of product data and distributing, it automatically to the people who need it - when they need it. In this paper, we developed PRO browser with these PDM functions which have the functions of managing the information of product, process and organization consistently and inter-referencing efficiently the data required in enaluation. In the PRO browser, throughout the design process improvement, the generic environments are embodied which make it possible to reduce product development sycle time and improve the quality of design.
