Research On The Conceptual Design Of Earthquake Rescue Robot Based On The Integration Of Demand And Function Evolution

As a tool that can perform tasks in complex earthquake disaster environments,earthquake rescue robots are of great research significance.However,due to the limitations of robot technology,unclear requirements and unreasonable design,the existing earthquake rescue robots still have problems such as poor terrain adaptability,insufficient environmental perception ability and low rescue efficiency,which limit the reliability of earthquake rescue robots in practical applications.Based on the theory of demand evolution and functional evolution,this thesis takes earthquake rescue robots as research objects,applies demand evolution and functional evolution theory to the functional innovation process of earthquake rescue robots,puts forward the modules that need to be improved by earthquake rescue robots based on user needs and existing problems,and puts forward corresponding design strategies to carry out the conceptual design practice of earthquake rescue robots.Firstly,the research status of demand evolution theory and functional evolution theory is sorted out,and the product function innovation process based on demand evolution and functional evolution integration is sorted out.Secondly,through questionnaire surveys,user interviews and other methods,the rescue team members and the people in the disaster area were investigated by users,the functional requirements of earthquake rescue robots were sorted out and analyzed,and the existing earthquake rescue robots were analyzed as case studies,and the shortcomings of existing related products were summarized.Thirdly,the functional layout and overall architecture of the existing earthquake rescue robot are analyzed,the functional structure model of the earthquake rescue robot is obtained,the module that needs to evolve the earthquake rescue robot is summarized by combining user needs and existing deficiencies,the direction of product function evolution is determined by using the law of demand evolution,and the correlation between demand evolution and functional evolution is combined to obtain the way of product function evolution,build a product function evolution set,and derive product design strategy.Finally,combined with the design strategy,the concept design of the earthquake rescue robot is carried out and the output design scheme is summarized and evaluated.This thesis investigates and analyzes the earthquake rescue robot from the demand layer and the functional layer,and obtains the conceptual design scheme of the earthquake rescue robot,which provides certain reference value for the design of emergency rescue products,but the earthquake rescue robot still needs further exploration and research from the conceptual design stage to the application in field rescue work.The thesis has 42 figures,20 tables,and 81 references.
