目的 为解决老龄化社会需求下的厨房设施操作面板设计问题,提高老年用户在使用智能集成灶时的操作体验,减少使用中失效模式的发生。方法 首先,成立IFMEA小组,同时确定20位老年用户人群,改进小组由数据收集员、产品设计师、交互设计师组成,之后选择集成灶操作面板品牌,利用HAZOP方法讨论得出失效模式出现的原因,同时对失效模式进行后果、措施分析;其次,绘画用户旅程图,了解用户心理以及使用目的,基于用户旅程图中遇到的问题构建指数风险优先计算模型,得出指数风险优先数值后,再利用故障树分析顶事件失效模式,对顶事件进行深度分析;最后,对改良集成灶屏幕设计进行对比验证。结果 通过相关理论得出老年用户在使用集成灶操作页面过程中的8项不可容忍失效模式,针对不可容忍失效模式进行重新设计优化,设计结果可提升老年用户使用体验。结论 对选取集成灶操作面板案例进行分析,最终结果表明通过所提出的方法能够使老年用户便捷操作,减少使用障碍,其结果也可为其他适老化设备和用户体验提供帮助。
Abstract
The work aims to solve the problem of kitchen facility operation panel design under the needs of the aging society, improve the operation experience of elderly users when using intelligent integrated stoves, and reduce the occurrence of failure mode during use. First of all, an IFMEA team was established, and 20 elderly users were identified. The improvement team was composed of data collectors, product designers, and interaction designers. After selecting the brand of the integrated stove operation panel, the HAZOP method was used to discuss the causes of failure modes during use, and the failure mode consequences and solutions were analyzed. Secondly, a user journey map was drawn to understand the user's psychology and purpose of use, build an exponential risk priority calculation model based on the problems encountered in the user journey map, and obtain the risk priority value. Then, the fault tree was applied to analyze the failure mode of the top event and conduct in-depth analysis of the top event. Finally, the design of the improved integrated stove screen was compared and verified. Eight intolerable failure modes were obtained by the IFMEA theory for elderly users in the process of using the integrated stove operation page. The redesign and optimization of the intolerable failure mode could improve the experience of elderly users. The case of selecting the integrated stove operation panel is analyzed, and the final results show that the proposed method can make the elderly users operate easily and reduce the use barriers, and the results can also provide help for other elderly-oriented equipment and user experience.
