目的 针对现有抑郁症康复设备因功能割裂、交互冷漠等造成的用户体验差、情感回应弱、使用依从性低等问题,探索一种以工业设计为主导、兼顾临床有效性与情绪关怀的产品改良设计策略,促进构建更贴近用户心理与行为特点的康复系统,提升患者对此类产品的接受度。方法 运用Kano模型与QFD方法,建立从多维心理需求识别到设计参数转化的系统工具链,引入冲突消解算法与“双螺旋结构模型”,在用户需求链与技术实现链之间建立动态耦合,建立“情绪感知-技术响应-动态调节”闭环,使产品方案随用户状态变化自适应迭代。结果 通过调研确诊用户、家庭医生与运维人员三类人群,提炼出操作简便性、隐私保护、情绪反馈等关键诉求,构建QFD权重矩阵与功能优先级排序,以Apple Watch App改良设计为例在微观交互层对该策略系统进行验证。结论 研究表明,“Kano-QFD-双螺旋”改良设计策略具有合理性和可迁移性,可为抑郁症康复设备、可穿戴产品及情感化交互系统设计提供支持,为“以用户情绪为核心”的产品创新提供了新的可行路径。
Abstract
Addressing issues of poor user experience, weak emotional response, and low compliance in existing depression rehabilitation devices due to fragmented functions and impersonal interactions, the work aims to explore a product improvement design strategy led by industrial design and integrating clinical effectiveness and emotional care, to facilitate the development of rehabilitation systems more aligned with users' psychological and behavioral characteristics and enhance patient acceptance of such products. The Kano model and QFD method were employed to establish a systematic toolchain from multidimensional psychological needs identification to design parameter translation. Conflict resolution algorithms and the "double helix structure model" were introduced, creating dynamic coupling between the user demand chain and the technical implementation chain, and establishing an"emotion perception-technical response-dynamic adjustment" closed loop, enabling product solutions to adapt iteratively according to users' state changes. Through surveys of diagnosed users, family physicians, and operation personnel, key requirements such as ease of use, privacy protection, and emotional feedback were identified. A QFD weight matrix and function priority ranking were constructed, and the strategy system was validated at the micro-interaction level with the Apple Watch App redesign as an example. The study demonstrates that the "Kano-QFD-double helix" improvement design strategy is reasonable and transferable, providing support for the design of depression rehabilitation devices, wearable products, and affective interaction systems, offering a new feasible path for "user emotion-centered" product innovation.
