基于TRIZ冲突解决理论的老年用品可用性设计方法

Usability design method of elderly products based on contradiction in TRIZ

为有效解决老年用品可用性设计中的冲突问题,将可用性与冲突解决理论融合,提出一种老年用品可用性设计方法。由于传统TRIZ参数对老年用品的不适用和模糊性,在老年用品的可用性设计中难以获得解决方案。从老年用品的可用性设计冲突入手,将TRIZ的工程参数筛选出老年可用性设计领域的26个专属可用性参数,采用灰色关联分析法对参数进行可用性分类,从感知层、认知层和执行层进行冲突矩阵的重构;建立了基于冲突解决理论的老年用品可用性设计过程模型,并应用于老年药盒的可用性设计实例。结果表明:文中方法能系统化地解决老年用品可用性设计中的冲突问题,使老年用品可用性设计方法和TRIZ的应用领域得到进一步拓展。

In order to effectively solve the conflict issue in the usability design of elderly products,a usability design method for elderly products was proposed by integrating usability and conflict resolution theory.Due to the inapplicability and ambiguity of traditional TRIZ parameters for elderly products,it was difficult to obtain solutions in the usability design of elderly products.Starting from the conflict of usability design of elderly products,the engineering parameters of TRIZ were screened into 26 exclusive usability parameters in the field of usability design for the elderly.Grey correlation analysis was applied to classify the parameters.The conflict matrix was reconstructed from perception layer,cognitive layer and execution layer.The usability design process model for elderly products was established based on conflict resolution theory.The proposed method was applied to the usability design case of the elderly medicine box.The results showed that the proposed method could systematically solve the conflict problems in the usability design of elderly products,and further expand the application fields of the usability design method and TRIZ.
