基于AHP与TRIZ的残障人轮椅设计

目的针对轮椅无法满足残障人使用的现状,提出集成层次分析法与发明问题解决理论的残障人轮椅创新设计。方法利用调研法及亲和图法确定残障人轮椅使用需求,并对需求进行层次分级。运用层次分析法获取分级需求重要度,将需求重要度降序排序,准确掌握轮椅设计的重点。建立用户需求—技术方案关系矩阵,验证技术方案是否存在矛盾冲突并运用发明问题解决理论的发明原理寻找最优解。结论依据层次分析法所得客观数据掌握设计重点,通过发明问题解决理论解决技术措施中的冲突,实现了残障人轮椅的创新设计,验证了多理论结合使用的有效性与科学性。

Design of Wheelchair for the Disabled Based on AHP and TRIZ

The work aims to propose the innovative wheelchair design for the disabled based on AHP and TRIZ, regarding the present situation that wheelchairs are currently unable to meet the needs of people with disabilities. The survey method and the affinity graph method were used to determine the wheelchair use needs of the disabled and grade the needs. AHP was used to obtain the importance of graded demands and sort the importance in descending order to accurately grasp the key points of wheelchair design. The user needs - technical solution relationship matrix was established to verify whether the technical solution had conflicts and the invention principle of TRIZ was applied to find the optimal solution. According to the objective data obtained by AHP, the design focus is grasped, and TRIZ solves the conflicts in the technical measures, which contributes to the realization of the innovative wheelchair design for the disabled. The realization proves the effectiveness and scientificity of the combination of multiple theories.
