| The forest fire risk problem in the southwestern mountainous areas of China is severe.However,the light fire extinguishing equipment used by the forest fire brigade currently has problems such as single function,low fire extinguishing efficiency,and inconvenient operation,which cannot effectively complete the forest fire extinguishing task.This article is based on TRIZ theory and uses the material field model and demand evolution theories in TRIZ theory to study the design of fire extinguishing equipment in the forest fire environment of southwestern mountainous areas.The specific research process is as follows: Firstly,analyze the forest fire scene in southwestern mountainous areas,determine the requirements for fire extinguishing equipment in this environment,and study the functions of existing forest fire extinguishing equipment.Secondly,the functional set of forest fire extinguishing equipment is obtained through principles such as material field models and technical contradictions.Thirdly,conduct user requirement analysis,using TRIZ requirement evolution theory and KANO model to analyze and classify the preliminary requirements obtained from the survey questionnaire,in order to obtain new requirements.Fourthly,the user demand results obtained will be substituted into the TRIZ demand function incidence matrix to obtain the function evolution set corresponding to each demand.And use TRIZ evolution theory to coordinate the functional conflicts generated by scenario analysis and user requirements.Fifthly,use TRIZ technology contradiction matrix and innovation principles to conduct specific design research and generate preliminary design solutions.Perform ergonomic simulation verification of the design scheme using JACK human factors engineering simulation software,and based on the results of simulation verification,further improve and optimize the preliminary design scheme using TRIZ requirement evolution theory.Finally,the fire extinguishing effectiveness of forest fire extinguishing equipment was verified through comparative analysis of the usage process and forest fire scenarios.The project is guided by TRIZ evolution theory to design light forest fire extinguishing equipment,and explores the application of TRIZ evolution theory in light forest fire extinguishing equipment,which has certain theoretical significance.The design of light forest fire extinguishing equipment studied by the research institute has solved the shortcomings of existing forest fire extinguishing equipment such as poor mobility,poor fire extinguishing efficiency,and poor experience.While optimizing fire extinguishing efficiency,it better meets user needs and provides a more effective fire extinguishing equipment for forest firefighters,which has certain practical significance. |
