【Abstract】 To solve the problems such as significant accumulation of dust particles at the air vents of the air conditioning system during the ventilation process of subway train operation, which leads to a substantial decline in the air quality inside the carriages, the work aims to adopt KANO/TRIZ theoretical methods for the innovative design of the air conditioning cleaning device. Starting from the existing cleaning methods, the KANO analysis method was used to identify the user requirements for train cleaning methods. The Nine-Window Diagram method of TRIZ theory was applied to establish an analysis matrix from three dimensions of component composition, operation sequence, and system correlation. Combined with the causal analysis method, the causes of the shortcomings of the current cleaning devices were revealed. Based on the results of defect analysis, tools of TRIZ theory such as the Ideal Final Result(IFR), Smart Little People Method, and Substance-Field Model were used to conduct the innovative design of the cleaning device, resulting in multiple sets of preliminary schemes. Finally, the main structural types of the supporting parts in the schemes were compared. By establishing models of different supporting structural parts, stress simulation experiments were carried out with the finite element method to screen out the optimal structural parameters. Through the integrated analysis and design method combining KANO, TRIZ, and finite element simulation, the existing problems in the cleaning of subway air conditioning systems were effectively solved. This method provides technical support for subway air conditioning maintenance and air quality assurance, and offers reference for the innovative design of similar equipment in rail transit.更多还原
