Innovative Design of Hose Winding Device based on TRIZ Theory

At present, the water hose is usually emptied, cleaned and rewound manually by means of a simple winding device in China, which has a large workload and low efficiency. In this paper, the TRIZ theoretical problem identification tool is used to analyze the water hose winding device existing in the domestic market, and it is found that the winding device lacks the mechanism of extruding the internal deposits, and the mud scraper has insufficient effect of removing external pollutants. Then the TRIZ theoretical problem solving tool is used to develop and design a water hose winding device integrating the functions of cleaning, emptying and winding. The paper focuses on the innovative design of the overall structure and driving, transmission, winding, cleaning and other mechanisms of the water hose winding device. The innovative design of the water hose winding device has simple structure, reliable operation and high efficiency, and has strong promotion value in the fields of fire protection, oil transmission, agricultural drainage and irrigation, and industrial and mine water delivery and drainage.
