European directive DIRECTIVE 2002/96/EC requires the minimum recycling & recovery rate on the waste electrical and electronic equipments (WEEE). But, they do not have guidelines on the calculation methods for recycling and recovery rate. A standard method to calculate recyclability and recoverability rate of products in the designing stage is necessary for the manufacturers so that they can reflect the calculated result to the improvement of product design. In this work, we investigated the existing calculation methods for the recycling and recovery rates of WEEE and the recyclability and recoverability rates of electrical and electronic equipments (EEE). A method for the calculation of recyclability and recoverability rates for the EEE products in the development stage was developed. The newly-developed calculation method was applied to some EEE products and the calculated results were evaluated.

The paper deals with the introduction of creative engineering design education in School of Mechanical Engineering, Yonsei University. The course is referred to as Creative Mechanical Engineering Design (1) for 2nd-year undergraduates who newly enter a major in mechanical engineering. This course emphasizes creative thinking and practical experiences to students by learning engineering design skills, realizing their idea through problem based learning (PBL) and design project and recognizing actual results of a product. The paper describes course contents, and discusses students’ responses to lecture, PBL and design projects.

Recently, IoT technology has great attention and plays a key role in 4^th industrial revolution in order to design customized products and services. Additive Manufacturing (AM) is applied to fabricate IoT sensor directly or IoT sensor embedded structure. Also, design methods for AM are developing to consolidate various parts of IoT devices. Part consolidation leads to assembly time and cost reduction, reliability improvement, and lightweight. Therefore, a design method was proposed to guide designers to consolidate parts. The design method helps designers to define product architecture that consists of functions and function-part relations. The product architecture is converted to a network graph and then Girvan Newman algorithm is applied to cluster the graph network. Parts in clusters are candidates for part consolidation. To demonstrate the usefulness of the proposed design method, a case study was performed with e-bike fabricated by additive manufacturing.

진공청소기의 인체적합도를 위주로 한 제품평가 방법을 개발하였다. 기존 감성공학에서 자주 사용해온 의미미분법을 근간으로 하고 다속성의사결정론 등을 가미한 평가방법이다. 30 개의 청소기를 대상으로 한 예비 평가실험을 통해 평가항목에 대한 요인분석을 실시한 후 평가항목을 설정하였으며, 평가항목과 상관관계가 높은 제품 속성들을 평가를 위한 설계요소로 설정하였다. 본 실험에서는 예비실험을 통해 개발된 평가방법을 이용해 30 명의 피실험자가 진공청소기를 대상으로 한 평가실험을 수행해 평가방법을 검증하였다.

Shipbuilding is a kind of ETO(Engineering To Order) industry which designs and produces a product in accordance to various requirement of customers, rules and regulations. Recently, the number of ordered ships has been increased by up to two or three times in each domestic shipyards. Most shipyards have been adopted 3D ship CAD, ERP(Enterprise Resource Planning) and APS(Advanced Planning System) to get an efficient product development and manufacturing system. However, not only the effective operation of 3D ship CAD, ERP and APS but also the production efficiency can be achieved only if product information management which can manages the product data is implemented in an integrated environment. Present study has suggested a systematic approach to implement a PLM system to manage the product data in early design shipbuilding. Also, a prototype of PLM is implemented to manage the product data in a basic ship-design. In the prototype system, a product structure and architecture of PLM is considered.

The TRIZ theory which was invented by Russian scientist Genrich Altshuller provides a systematic methodology for innovative engineering design in place of brainstorming. synectics, analogical thinking, which seeming1y high efficiency are still variations of the trials and errors method. TRIZ theory gives designer the ability to explore design solutions in fields other than his (her) own experience. Among several TRIZ theories, most widely used techniques in engineering field are contradiction theory. Su-Field analysis, physical phenomenon and effect and directed production evolution. which are described in this thesis and its application to conceptual design of high-speed train is performed as a case study of TRIZ theory.

By conducting multiple regression analysis, we analyzed the major independent factors affecting user convenience and emotional factors, and identified the important functional elements in the design of the VR device, so that the functional elements to be developed can be grasped in advance. As a result of the study, satisfaction of handling of VR bicycle and satisfaction of speed control by paddling were considered as the most important technical factors as independent factors which have the greatest influence on user convenience and emotional factor among technical satisfaction. Also, it is possible to increase the probabilities of successful design by setting a model that predicts user convenience and the emotional part from the technical factors.
