Abstract:

In response to the pressing issue of insufficient rescue equipment in snowy environments, a functional requirement index system for intelligent snow rescue equipment was established to achieve a quantitative evaluation of design requirements for snow rescue equipment. The AHP-TRIZ theory was explored to provide a theoretical basis for the conceptual design of snow rescue equipment. Extensive research was conducted from the perspective of product functional requirements, which involved obtaining user requirement elements through literature research and survey methods. The analytic hierarchy process (AHP) was then employed to summarize the functional requirement indicator system for snow rescue equipment from three levels: objectives, criteria, and indicators. Utilizing the 1-9 scale method, the design requirements of snow rescue equipment were subjected to quantitative evaluation, and consistency testing was completed. Additionally, by integrating the Archishuler contradiction matrix theory from the Theory of invention problem solving (TRIZ), the study identified the parameters requiring improvement and corresponding deterioration. It further explored efficient solutions for 39 engineering parameters and 40 invention principles in TRIZ, resolving conflicts between multi-level design elements and achieving the optimal configuration. Thoroughly identifying the requirements for snow rescue equipment in terms of functionality, appearance, ergonomics and technology, etc., the study successfully accomplished the conceptual design of snow rescue equipment. In response to the challenges posed by harsh environments in snow-covered areas, the subjective judgment results were quantified and processed through the integrated AHP-TRIZ method. This approach not only provided methodological guidance for the design of snow rescue equipment but also enhanced the scientific and rational nature of the design.
