In this paper, a redesign of computer case is proposed by applying some guide lines of assembly and disassembly to an existing computer case. Some problems such as increase of number of disassembly and vibration, difficult assembly and disassembly from unfittable covers are recognized through analysis of geometrical structure and practical assembly and disassembly. A solution of these problems is proposed through ideas of ease of assembly and disassembly. Design for Environment Software is used to evaluate both redesigned and existing products. Time of assembly and disassembly and MET-point are especially calculated by the software, and these data give us a good guide for analysis of ease of assembly, ease of disassembly and environmental influence in both products.

In this paper, a redesign of an existing computer case is Proposed by applying some guide lines of assembly and disassembly which have positive effects on environment. Some problems such as Increase of number of disassembly and vibration, and unfittable difficulty in assembly and disassembly of coy-ers are recognized through analysis of geometrical structure in view of both assembly and disassembly. A solution of these problems is proposed by ideas of positive environmental influence through ease of assembly and disassembly. Design for Environment Software is used to evaluate both redesigned and existing products. Time of assembly and disassemb]y and MET-point are especially calculated by the software, and these data give us a good guide for analysis of ease of assembly, ease of disassembly and environmental influence in both products.

In this paper, a disassemblability evaluation has been investigated quantitatively by using an ease-of-disassembly design method. Four categories such as recognizability, approachability, separability, and treatability have been analyzed in details. A simulation software for estimating the ease-of-disassembly design method has been developed and applied to door trim and spin basket respectively as an example.

De-manufacturing is an entire process of collecting, disassembling, reusing, refurbishing, recycling, and/or disposing products that are obsolete or un-repairable. Designing the products for inexpensive and efficient disassembly enhances the ease of de-manufacturing. Virtual disassembly addresses the difficulty and the methods to disassemble a product in design stage rather than really disassemble a product at the end of its life cycle. Based on the virtual disassembly analysis results, design will be improved for better assembling/disassembling. This paper presents a systematic virtual disassembly methodology such as disassembly relation modeling, path/sequence automatic generation and evaluation. This paper also presents a new virtual disassembly interface paradigm via virtual reality technology for disassembly simulation in virtual environment.

In this paper, to propose guideline of modular design for improvement of ease of disassembly, product structure must be considered. By analyzing characteristics of structure of subassembly, influencing factor of module can be defined and classified. Based on determination factor of influencing factor of module, criteria for improvement of ease of disassembly can be obtained through the interrelationship between product and process factors.

Recently Environmental issues is Product development for ease of disassembly and recycling requires methodical toolboxes and respective infrastructures of information and communication technology. Therefore, today's designers have a very high level of product responsibility as disassembly is a major cost factor of product recycling. A study on the product redesign Methods and tools for sustainable management.

본 연구에서는 재제조를 용이하게 하기 위하여 분해용이성 및 분해시간 산출이라는 두 가지 방법을 이용하여 부품의 분해성 평가 방법을 제시하였다. 또한 부품별 평가로부터 얻어진 분해성 지수로부터 최소 부품수의 개념을 이용하여 제품의 분해성을 도출하는 방법을 개발하였다. 제시된 방법들을 컴퓨터의 외장 케이스에 적용하여 비교 분석하였다. 분해용이성 및 분해시간의 분석에 의한 분해성 평가는 케이스의 일부 분리를 용이하게 한 새 모델이 재제조를 위한 전체 분해시에는 오히려 분해성이 악화된다는 동일한 결론을 보여주었다. 이러한 분해성 평가 방법은 제품의 재제조 및 재활용 특성을 평가하는데 중요한 지표중의 하나로 사용될 수 있을 것이다.

Today the tastes of consumers change rapidly and the kinds of the products become diverse. There- fore the product life cycle becomes shorter and shorter. Moreover the save of resources and the recycling for the environmental preservation are the essential theme. On this the necessary information for the product development increases enormously. For the right use of the information the design process should be supported by the proper design tool. For this the 'design catalogue system for recycling' is suggested here. This system consists of four parts. that is, 'the existing automobile system database', 'welting principle database', 'Assessment system of the ease of disassembly' and 'one's own product development ratabase'. By the use of this system the product development period could be reduced about 30% drastically.
