设计任务驱动的工具类产品创新

基于传统工程设计框架，设计人员在工具类产品设计初期很少考虑社会技术因素，用户在完成具体任务实现物料加工的过程中所产生的产品交互等实际问题易导致工具类产品本身的设计迭代。通过集成不同的设计理论与方法，如社会技术系统理论(social technology system, STS)、情景分解法、任务分析法、FBS(function-behavior-structure, FBS)模型、TRIZ(teoriya resheniya izobreatatelskikh zadatch)等，在设计阶段融入对使用者的要求，针对工具类产品建立一种以设计任务驱动的产品创新设计过程模型。将工具类产品创新设计过程模型分为设计任务识别、设计任务分析与设计方案产生三个阶段。首先利用情景分解法与任务分析法结合并引入功能分析进行量化来发现、确定设计任务；从社会技术因素与技术因素两方面研究FBS模型，利用功能模型等方法分析设计任务，引入时间参数构建任务元——时间模型；在设计方案产生阶段通过构建基于任务元的设计方案产生过程模型，确定最终设计方案。以曲线锯为例验证了该设计过程的有效性，研究有助于提高产品创新设计效率，减...

Innovative design of tool products driven by design task

Based on the traditional engineering design framework, designers rarely consider social-technical factors in the early stage of tool product design. The actual problems when users completing specific tasks to achieve material processing are easy to lead to design iteration. By integrating different design methods, such as Situation Decomposition method, Task Analysis method, FBS model (FBS, function-behavior-structure), etc., a design task -driven product innovation design process model is established for tool products. In the design stage, Integrating research on user information can improve product performance, optimize user experience and reduce design iterations. The tool product innovation design process model is divided into three stages: design task identification, design task analysis and design plan generation. Firstly, the Situation Decomposition method is combined with the Task Analysis method and the Functional Decomposition is introduced to quantify and determine the design task; Then the FBS model is studied from the social-technical factor and the technical factor, the functional model is utilized to analyze design task, introducing the time parameter to obtain the task meta-time model; constructing the design plan generation process model based on the task meta in the design stage to determine the final design. Taking the jig saw as an example, the application of the innovative design process model is studied to improve the efficiency of product innovation design and enrich the research theory of design-driven product innovation.
