Research On Design Mode Of Fire Fighting Robot Based On QFD/TRIZ Integration

With the rapid development of industry nowadays,various types of fires continue to occur,and the internal environment of the fire scene is complicated.It is very necessary for fire-fighting robots to replace or cooperate with firefighters to detect and rescue fire scenes.Fire-fighting robots can greatly detect fire scenes and rescue operations.Enhance the efficiency of fire fighting work.The demand in the field of fire safety in China is rising rapidly,and the development of fire-fighting robots is also very rapid.Innovative design research is carried out from the perspective of user needs of fire-fighting robots.First,QFD theory is used to study user needs and related factors through user interviews and questionnaire surveys,and the affinity diagram method is used to optimize and layer related factors,and reflect the design of fire-fighting robots to users The24 sub-problems of safety,quality performance,modeling design,and reliability are sorted out,and demand weights are obtained;secondly,a house of quality is established to introduce the technical contradiction between user needs and quality characteristics into TRIZ theory;again according to TRIZ theory The S-curve,the most ideal solution,the dynamic evolution rule and 40 invention principles in the evolutionary law of technological systems solve key issues such as battery life,explosion-proof,sensors,positioning and navigation,and obtain innovative design solutions for fire-fighting robots;finally forecast based on demand The principle evolves the new demand into the innovative design direction of product technology.The design practice of fire-fighting robots is carried out according to the new design direction,and the feasibility of using QFD/TRIZ theory to integrate theoretical methods for fire-fighting robots is verified.Finally,the analytic hierarchy process is used to establish an evaluation model for the fire-fighting robot,and the best design plan is selected.Provide an accurate and scientific method and research ideas for the development and research of fire fighting equipment,so as to better protect the safety of people’s property.
