This paper presents a content-search system built on distributed environments using the open product model of STEP, The content-search system searches design data for given product descriptions such as part name and features. Distribute object interfaces has been defined by IDL and distributed product data are searched through CORBA protocols. Web interfaces are also provided for interactive user interfaces. Given a user request, a mediator interacts with distributed search servers and sends collected results back to the user. The mediator has such metadata as location, program name, and other information about product data stored on distributed system. The search servers use SDAI interfaces to search STEP files or databases. The content-search system promotes the reuse of previous design within a company and the outsourcing of part designs.

Service-Oriented Architecture (SOA) is a new trend for the design of application architecture to enhance the degree of share and reuse with the concept of service. It comes from the current situation where the business environments are changing rapidly and therefore competitions are getting bitter. To cope with such business challenges, business (and/or applications) architecture needs considerably flexibility and reusability, and that's why SOA is accepted as one of the most effective framework for the business applications in these days. In this paper we propose an analysis and design methodology for the applications of SOA. To implement the proposed methodology, the service ontology needs to be defined first, and the tasks such as service profiling, workflow design and service orchestration need to be followed. To validate the expected effects on flexibility and reusability, the proposed methodology was compared with CBD (Component Based Development).

Reusing is one of the most environmentally friendly recycling methods. For the economical remanufacturing of used cellular phone, the cellular phones should be design for easy disassembly. In this paper, we analyzed the components and connecting elements of cellular phones and developed a guideline for the design of the cellular phones. A software for the disassembly assessment was also developed. Redesigned cellular phone by the developed guideline and its original phone was analyzed by the disassembly assessment software. Disassembly time could be reduced about 40% and reusing rate could be improved about 37%.

The attempt of the contemporary society to overcome the environmental crisis is considered what the whole world is currently interested in. Since value of resources recycling has become emphasized even more, the field of design is, now, working hard to prove how much they are passionate about this eco-friendly design. Of all those activities that the field of design is involving in, a concept called 'upcycling' is receiving the greatest spotlight as a new trend. When it comes to upcycling, you should understand it as a both functional and aesthetic upgraded idea of conventional 'recycling' which would re-use waste resources. With this upcycling, you will have a chance to re-create an object of a new value, and it is a design concept which would consider environmental aspects but also social aspects. Since the year of 2000, the field of furniture design has been pursuing a new design trend which would intensively concern this upcycling concept. In the light of the present circumstances described on the above, this study conducts a case analysis on how upcycling of different materials is applied to furniture design since the year 2000. In doing so, the study improve understanding on furniture design as proposing new ways for you to look at the concerned design. Not only that, it also comes up with ideas and directions for new upcycling furniture design which could be demanded by the environmental industry.

This work is mainly done by too many manual operations in the aircraft structure design process resulting in heavy workload, low efficiency and quality, non-standardized processes and procedures. A top-down associated design method employing the template parametric technology is proposed here in order to improve the quality of design and efficiency of aircraft wing structure at the preliminary design stage. The appropriate parametric tool is chosen and the rapid design system of knowledge-driven aircraft wing structure is developed. First, a skeleton model of aircraft wing structure is rapidly built up through the template encapsulated design knowledge. Associated design is then introduced to realize the association between the typical structural part and skeleton model. Finally, the related elements are referenced from skeleton model, and a typical structural part reflecting an automatic response for design changes of the upstream skeleton model is quickly constructed within the template. The rapid design system proposed and developed in this paper is able to formalize the design standardization of aircraft wing structure and thus the rapid generation of different aircraft wing structure programs and achieve the structural design knowledge reuse as well.

Disassembly is a fundamental process needed for component reuse and material recycling in all assembled products. Integral attachments, also known as 'snap' fits, are favored fastening means in design for assembly (DFA) methodologies, but not necessarily a favored choice for design for disassembly. In this paper, design methods of a new class of integral attachments are proposed, where the snapped joints can be disengaged by the application of localized heat sources. The design problem of reversible integral attachments is posed as the design of compliant mechanisms actuated with localized thermal expansion of materials. Topology optimization technique is utilized to obtain conceptual layout of snap-fit mechanisms that realizes a desired deformation of snapped features for joint release. Two design approaches are attempted and design results of each approach are presented, where the geometrical configuration extracted from optimal topologies are simplified to enhance the manufacturability for the conventional injection molding technologies. To maximize the magnitude of deformation, a design scheme has been proposed to include boundary conditions as design variables. Final designs are verified using commercial software for finite element analysis.

Zero-waste pattern cutting is a groundbreaking sustainable fashion practice. However, few brands and designers have pursued this method because it requires creative pattern design that diverges from the existing process of using pattern slopers. Therefore, application within the fashion industry is not sufficient. Therefore, in an attempt to highlight the key characteristics of zero-waste pattern design, this study classifies and analyzes cases in which similar designs employ zero-waste pattern-cutting techniques. We hope to make zero-waste pattern design more accessible by presenting realistic pattern-cutting guidelines. To this end, theoretical research on relevant literature, previous research, and online resources and an empirical analysis of cases involving zero-waste pattern cutting were conducted in parallel. As a result of the study, we were able to classify the factors of zero-waste pattern design in terms of fabric use, design, and composition. Regarding materials, our research revealed the importance of appropriate fabric width, understanding the difference between waste minimization and minimal fabric use, and easy reuse and recycling. In terms of design, the simultaneous progress of pattern and design work, adjustable loose silhouettes, and the use of surplus fabric for functional and decorative details emerged as key characteristics. For composition, we found that size adjustment limits, arrangement irregularity, and pattern shapes were crucial elements and that various arrangements revealed unlimited design potential.

This study is about the design for environment which is central social interest in recent days. This study focused on both experimental designs which convey meanings and practical designs which can be produced within the fashion industry and then influence on the wide range of consumer, human and surrounding environment. The purposes of this study are to categorize national and global fashion designs for environment, to analyze data based on the fashion pipeline from planning to discard, to suggest systematic actions, and to establish fashion design for environment model. Through these processes, this study helps in making fashion designs for environment more understandable, and demonstrates one future direction for using environment as fashion industry's innovative strategy. This study attempts to create business and at the same time suggests design actions based on social belief. The results of this study are following. Fashion designs for environment were categorized by organic fabric, new-to-the-world fabric, reduce, multi-function, reproduce, order-made, recycle, and reuse. The results show that fashion designs for environment have been implemented throughout the fashion pipeline, and applied the concepts of design for environment including green, sustainable slow, and natural design principles. Furthermore, labelling and service from supply side, green purchasing from demand side, and integration from both sides are suggested as company's and society's systematic actions.
