초록

최근 4차 산업혁명으로 인하여, 고객 제품형 제품 설계 및 새로운 서비스 개발을 위하여 IoT 기술이 주목받고있다. 최근 적층제조 기술은 IoT 센서를 직접 제작하거나, 센서를 포함한 기기를 만드는 분야에 다양하게 활용되고 있다. IoT 기기를 적층제조를 활용하여 제작시, 적층제조 고유의 설계 장점을 활용하기 위해 다양한 부품들을 병합하는설계 방법론이 큰 관심을 받고 있다. 부품병합을 통해 조립 공정을 단축하고, 부품 경량화 등의 장점을 이룰 수 있기때문이다. 따라서, 본 연구에서는 적층제조를 활용한 부품병합을 지원하기 위한 설계 방법론을 개발하였다. 이를 통해제품의 기능 및 제품 내 부품의 기능과 물리적 연결성을 분석한 제품 아키텍쳐를 생성하고, 인접한 기능들 및 부품을Girvan Newman 알고리즘을 활용하여, 최종 부품병합 후보군을 선정하도록 지원한다. 제안한 설계 방법론을 검증하고자 사례연구를 통해 적층제조로 출력된 전기 자전거의 부품병합과정을 분석하였다.

Abstract

Recently, IoT technology has great attention and plays a key role in 4th 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.
