基于RAHP和QFD的智能空气净化器设计研究

Design of Intelligent Air Purifier Based on RAHP and QFD

目的有效获取用户对家用智能空气净化器的需求及其优先级,进一步将用户需求转化为设计要求,识别出智能空气净化器的关键设计要求,进而为设计提供参考依据,提升用户满意度。方法首先通过问卷调查以及访谈法获取用户需求,并利用亲和图法(KJ法)构建关于智能空气净化器用户需求的层次模型,再引入粗糙层次分析法(RAHP)获取各项用户需求初始重要度,同时运用模糊卡诺模型(FKM)确定各项需求类别,并基于需求类别引入调整系数对初始重要度进行调整,最后利用质量功能展开(QFD)将用户需求转化为设计要素,明确智能空气净化器的关键设计要求,指导智能空气净化器的设计。结论通过对智能空气净化器的用户需求进行较为深入的分析,将用户需求转化为设计要求,识别出了智能空气净化器在滤网模块、智能检测模块、信息显示模块、远程APP控制模块以及风速控制模块等方面的设计要求重要度较高,并以此为依据提出了设计方案,得到了用户较高的满意度,所得研究方法及流程可为设计出符合用户需求的产品提供参考。

The paper aims to effectively obtain user needs and priorities for home smart air purifiers,further transform user needs into design requirements,identify key design requirements for smart air purifiers,and provide reference for design and improve user satisfaction.First,user needs are obtained through questionnaire surveys and interviews,and af-finity diagram method(KJ method)is used to build a hierarchical model of user needs for smart air purifiers,and then rough analytic hierarchy process(RAHP)is introduced to obtain the initial importance of various user needs.At the same time,the fuzzy Carnot model(FKM)is used to determine the various demand categories,and the adjustment coefficient is introduced based on the demand category to adjust the initial importance,and finally the quality function deployment(QFD)is used to transform user needs into design elements.The key design requirements of the smart air purifier are cla-rified to guide the design of it.Through a more in-depth analysis of the user needs of the smart air purifier,the user needs are transformed into design requirements,and it identified that the design requirements of the intelligent air purifier in the filter module,intelligent detection module,information display module,remote APP control module and wind speed control module are of high importance.And based on this,a design plan is proposed,which has obtained high user satis-faction.The research methods and processes in the paper can provide references for designing products that meet user needs.
