Acquisition Model for the Product Functional Requirements Based on System Evolutionary Laws
-
摘要: 为了获取用户的兴奋需求作为产品概念设计的目标,基于技术系统进化法则并结合KANO模型提出了产品功能需求获取模型。对产品进行成熟度判定和功能分析;对产品所有功能模块逐个进行进化分析,找寻基于进化法则的功能需求目标解;基于市场调研的结果对功能需求目标解进行功能需求隶属分析;确定兴奋需求作为产品概念设计的任务空间,满足用户的兴奋型需求。本模型能够系统的求解用户兴奋型功能需求,文末给出实例,验证了该模型的有效性和可行性。Abstract: To get users' exciting requirements as the goal of conceptual design, integrating KANO model, an acquisition model for product functional requirements based on system evolutionary laws was proposed. Firstly, the maturity of the product was determined and then functional analysis was made. Secondly, evolutionary analysis of every functional module was made to find their corresponding evolutionary solutions based on system evolutionary laws. Then evolutionary solutions were considered with classification analysis based on market research. Finally, the excitatory demand was resulted as design targets in order to meet customers' exctatory demand. The present model could obtain the functional requirements systematically. The results could meet users' excitatory demand which were hardly generated from market research. The model was applied to find suited functional requirements of drinking fountains, and prove to be effective.
