Abstract: 충격이나 진동을 완화시키는 방법으로 스프링을 사용하는 방식이 주로 쓰인다. 
     기존의 완충방식은 스프링 정수가 사실상 고정되어 있기 때문에 다양한 세기의 충격을 하나의 스프링으로 흡수하기 어려워 2개 이상의 완충장치를 사용한다. 이러한 문제해결을 위해 스프링 정수가 충격강도에 맞춰 변화할 수 있는 완충장치를 개발하고자 했다. 본 발명은 짧은 거리에서 다양한 세기의 충격을 효과적으로 흡수하기 위해 지렛대 원리를 응용하였다. 제1도에서 보듯 보호하고자 하는 물체를 받쳐주는 축을 중심으로 한쪽에 스프링을 두고 충격은 반대쪽에서 받도록 하였다. 스프링에 힘을 전달하는 감쇄판의 특정지점과 축 사이의 직선거리는 변함없지만 감쇄판과 지렛판이 맞닿은 충격전달점과 축 사이의 직선거리는 변화하게 만든 것이 핵심이다. 충격이 바퀴 축을 통해 전달되면 감쇄판이 기울게 되고 지렛판 모양에 의해 축과 충격전달점의 직선거리가 짧아지게 되어 감쇄판은 지렛대 역할을 하게 된다. 즉, 감쇄판을 통해 축과 충격전달점 사이의 직선거리가 충격의 세기에 따라 연속적으로 변화하면서 스프링은 충격의 세기에 맞춰 약한 충격에는 낮은 정수값을 갖고 강한 충격엔 높은 정수값을 갖는 효과를 얻는다. 완충장치를 본 발명과 같이 구성할 때 감쇄판과 지렛판의 접점인 충격전달점의 위치변화로 인해 발생하는 지렛대 효과 덕에 다양한 세기의 충격을 하나의 장치로 흡수할 수 있어 기존처럼 완충장치를 이중으로 설치할 필요 없기 때문에 경제적이며 공간을 절약할 수 있다.
