Study on vehicle-mounted snow-remover & deicer for trees based on TRIZ

For mission of emergency vehicle, the necessity and significance of its expansion function of rescuing trees covered with ice or snow was expounded. The function module of vehicle-mounted snow-remover & deicer for trees was proposed. Based on the theory of TRIZ, the technical contradictions and physical contradictions in the actuating mechanism of snow-remover & deicer were analyzed. The contradictions were expressed by using some general characteristics in TRIZ. The contradiction matrixes were established to find the innovation principles in order to look for the directions of creative thinking in design. By utilizing knowledge of mechanical engineering and experiences during design process, new ideas for domain solutions were generated. At last, the special solutions to the contradictions have been found.
