Abstract

Even in the era of the 4th industrial revolution, the prevention of industrial accidents is still an important issue in industrial sites. In solving the problem of industrial safety, a product can be difficult to market if there is a lack of standard or method for a reliable performance evaluation. The purpose of this study was to develop and evaluate a test method for a wearable airbag product for protecting the body from falls that was newly developed to respond to fall accidents in industrial sites. As a research method, reliable evaluation standards were developed and applied through four stages of the evaluation and development process (Step 1: Product review, Step 2: Data research, Step 3: Expert meeting, Step 4: Drawing evaluation standard). In addition, the impact force was evaluated according to the developed evaluation standard. The fall impact force obtained through the evaluation showed a reduction effect of approximately 96% compared to the existing impact force. Therefore, the fall impact force was reduced significantly when the airbag was applied. This will enable new convergence products to be launched on the market and produce an environment where industrial workers can work safely.

4차 산업혁명의 시대에서도 여전히 산업 재해 예방은 산업 현장에서 중요한 문제이다. 그런데, 산업 안전의 문제를 해결하는 과정에서 개발된 제품이 신뢰성 있는 성능평가에 대한 기준이나 방법의 부재로 시장 출시에 대한 어려움이 큰 상황이다. 본 연구의 목적은 산업 현장에서 추락 사고에 대응하기 위해 새롭게 개발된 추락 인체 보호용 착용형 에어백 제품에 대한 시험 방법개발 및 평가이다. 연구 방법으로는 기존에 없는 융합 신제품 평가개발 process 4단계(1단계: 제품검토, 2단계: 자료조사, 3단계: 전문가 회의, 4단계: 평가기준도출)를 통해 신뢰성 있는 평가 기준을 개발하고 적용하였다. 또한 개발된 평가 기준에 따라 추락 인체 보호용 착용형 에어백 소재에 대한 충격력을 평가하였다. 평가로 얻어진 추락 충격력은 기존 충격력 대비 96% 정도의 감소 효과를 나타내어 에어백 적용 시 추락 충격력이 현저히 줄어듦을 확인할 수 있었다. 이를 통해 융합 신제품이 시장 출시를 할 수 있도록 하였으며, 산업 현장 근로자가 안전하게 작업할 수 있는 환경을 조성하게 될 것으로 보인다.
