Abstract

In this study, we proposed a design guideline of height-adjustable wash basin which is an assistive product for personal hygiene for persons with disability. We performed biomechanical assessments using both of conventional and prototype height adjustable wash basin. Total five elderly subjects (all male, age $68.6{\pm}4.3yrs.$, height $169.8{\pm}5.7cm$, weight $70{\pm}7.7kg$) participated for the assessment test. Each joint angles were measured by using a 3D motion capture system when subjects use wash basins, and the lumbar moment of each subjects was estimated based on a human body model. From the assessment results, a design guideline which has the range of the height from 652[mm] to 1162[mm] was proposed. Then additional assessment tests with five healthy subjects ($25.8{\pm}1.8yrs.$, $175.5{\pm}5.8cm$, $74{\pm}15.7kg$) were performed in order to verify effectiveness of the design guideline. The results showed a height-adjustable wash basin applied the proposed design guideline was effective to reduce the lumbar moment.

본 논문은 개인위생(personal hygiene)을 위한 보조기기(assistive product)의 하나인, 고령자 및 장애인을 위한 높이조절 세면기의 설계 가이드라인을 제안하였다. 본 연구에서는 기존의 세면기와 프로토타입 높이조절 세면기를 이용한 생체역학적 평가를 진행하였다. 65세 이상 남성 5명(age $68.6{\pm}4.3yrs.$, height $169.8{\pm}5.7cm$, weight $70{\pm}7.7kg$)이 피험자로 참가하였으며, 피험자가 세면기 사용시 3차원 동작측정장치를 이용하여 인체각도를 측정하고, 인체모델을 이용하여 요추에 걸리는 모멘트를 추정하여 평가하였다. 이 결과로부터 최적의 높이 조절 가능 범위가 652[mm]에서 1,162[mm]인 설계 가이드라인을 제시하였다. 일반인 5명의 피험자($25.8{\pm}1.8$세, $175.5{\pm}5.8cm$, $74{\pm}15.7kg$)를 대상으로 높이 조절 세면기의 사용시 그 유효성을 평가하였으며, 그 결과 본 논문에서 제시한 높이조절 범위가 타당함을 보였다.
