Abstract

Recently, many laundry home appliances have been released with Internet of Things (IoT) functions, but there are few quality evaluation tests for IoT functions. In particular, since IoT test items are not prepared for laundry home appliances applied with IoT functions, it is difficult to find the cause even if defects occur, and test institutions are limited in selecting test items related to IoT and conducting proper performance tests. In this paper, we design a test item framework that separates IoT test items into commonality and variability to identify product defects and causes for laundry home appliances with IoT features among products in the field of home appliances. Through the proposed research, manufacturers and test institutions can test the proper performance of laundry products with IoT functions, which can improve the completeness of the products and ensure reliability.

최근 들어 세탁 가전제품은 사물인터넷(IoT) 기능을 적용한 제품이 많이 출시되고 있으나 IoT 기능에 대한 품질평가 시험은 거의 없는 게 현실이다. 특히 기존의 시험체제에서는 IoT 기능을 적용한 세탁 가전제품에 대해 IoT 시험항목이 마련되어 있지 않기 때문에 제품을 제조하는 제조사의 경우에는 결함이 발생하더라도 원인을 쉽게 찾기가 어려우며, 시험기관의 경우에도 IoT와 관련한 시험항목 선정 및 방법의 부재로 올바른 성능시험 수행에 제약이 있다. 본 논문에서는 가전기기 분야의 제품 중 IoT 기능을 적용한 세탁 가전제품에 대해 성능시험 프로세스에서 제품 결함을 찾아내고 그 원인을 식별할 수 있도록 IoT 시험항목을 공용성과 가변성으로 구분한 시험항목 프레임워크를 설계하고, 이를 이용한 시험방법 및 관리방안을 제안한다. 제안하는 연구를 통해 제조사 및 시험기관은 IoT 기능을 적용한 세탁 제품의 올바른 성능시험이 가능하여, 제품의 완성도를 높이고 신뢰성을 확보할 수 있다.
