자동차 정비 작업복의 기능적 디자인 연구

Abstract

The purpose of this article was to determine how the current auto mechanic's coverall restricts movements, to develop prototype coverall, and finally, to improve working efficiency. To investigate the problem and complaint of current coveralls, 35 mechanics were interviewed. Video captured method was used to analyze the representative movement. Based on the previous investigation, the prototype coverall was developed. Pleats and band were inserted on each side of the back, under the armhole, and the back waist area for flexibility. To analyze the mobility of current and prototype coveralls objectively, range-of-motion of selected movements was measured by Leighton flexometer and goniometer. Also, wearer acceptability scale was tested to investigate subjective preference of current and prototype coveralls. As subjects, 10 auto mechanics were participated. Order of testing was randomized. ANOBA and LSD were used for statistical analysis. As a results, prototype coverall was significantly different from current coverall at all test movements. Also, prototype coverall was significantly different from current coverall at 13 scales among 23 subjective scales. The results identified that prototype coverall design improved auto mechanic's body movement and subjective acceptability.
