Abstract: 본 발명은 맞춤신발의 제작 과정에서 착용자의 발에 맞는 신발 제작을 위하여 시행하는 가봉 단계에서 보조적으로 활용하는 장치와 방법에 관한 것으로서, 완성 직전의 신발이 발에 어느 정도나 잘 맞는지(fitting)를 압력 센서와 컴퓨터 시스템을 이용하여 수치나 그림으로 분석할 수 있는 장치 및 시스템에 관한 것이다.  
컴퓨터에 연결된 압력 센서들을 발의 주요 부위에 부착하고, 가봉 대상인 신발을 착용한 상태에서 발의 주요 부위에 부하된 압박의 크기가 컴퓨터로 전송되면, 모니터 화면에 디스플레이된 모형발에 각 부위의 압박의 크기가 수치와 그림으로 표시되어 발의 각 부위들이 얼마나 압박을 받고 있는지를 쉽게 파악될 수 있다. 
다시 말해서 본 발명은 신발 착용 상태에서 발의 주요 위치별로 파악된 압박 정도를 감안하여 신발 제작에 사용된 신골(shoe last)을 부분적으로 수정한 후 최종 신발 제작을 완성함으로써 발에 잘 맞고 편한 맞춤신발의 제작이 가능하도록 도와주는 장치 및 방법이다. 
본 발명에 의하면, 지금까지 맞춤신발 가봉 시 착용자의 주관적인 느낌에만 의존하여 신골을 수정하여 신발을 제작해오던 주먹구구식의 비합리적인 방식을 탈피하고, 신발의 가봉 분석 장치 및 방법을 활용함으로써 압력센서에 의한 객관적인 수치를 근거로 착용자의 발에 정확하게 맞을 뿐만 아니라 신발의 착용감까지 향상시킴으로써 고객에게 편안함을 제공할 수 있다.

Abstract: According to the present invention, a bottle washing brush is detachably and axially connected to a rotary shaft integrated with a dishwashing liquid vessel detachably and axially connected to a lower side of a motor-driven device, such as a motor-driven driver, and is rotated inside a bottle, so the inside of the bottle can be washed up. Moreover, a semi-permanent scrubber made of an elastic material, such as silicone, etc., and covered with a net washing fiber detachably and axially connected to a lower side of the bottle washing brush is rotated by the motor-driven device, so as to wash up dishes. Thus, since the scrubber reaches up to corners of the dish, the dish is cleanly and quickly washed up. Since an outer surface of the dish is washed up in the same way as an existing scrubber by attaching only the semi-permanent scrubber, so a user can quickly wash the dish without touching food pollutant, such as oil, etc., and thereby manpower is saved. The dishes and a deep cup and a bottle with a small mouse are effectively washed with one single washer, and the dishes are cleanly washed without the dishwashing liquid or with a small amount of the dishwashing liquid, so environment pollution is reduced and energy saving is realized with a remarkably small electric fee in comparison with a machine washer. Moreover, the scrubber is compact and beautiful in comparison with the existing scrubber, and is not worn out or getting mushy so as to be good in terms of appearance. The scrubber is easy to store, washes the dishes well, is not soaked by the food pollutant, and is autonomously cleaned by friction without requiring independent cleaning. Moreover, the scrubber does not scatter the food pollutant due to a lower operation speed, is prevented from being dropped in water due to a wrist band, and has durability. Moreover, the motor-driven driver can be promptly used for an original use and is cheap.
