【摘要】 针对神经康复理疗设备设计过程知识表达不充分,难以实现产品功构建模等一系列问题。将神经康复理疗设备的分解拓扑模型与模块化设计方法相结合,提出了需求(P)-功能(F)-原理(W)-行为(B)-结构(S)的神经康复理疗设备模块化设计总体模型,从而实现神经康复理疗设备多层次模块构建。以设计知识流理论为出发点,研究用户需求驱动下的产品模块分解方法,建立了一套神经康复理疗设备模块配置的支持系统。分析了设计分解过程中功能-原理-行为-结构演进的纵向迭代过程,加入原理模型作为设计的约束条件,探讨了功构模块创建原理与方法,建立DSM设计结构矩阵得出神经康复设备产品配置设计方案。以此为基础,构建了针对神经康复产品系统的模块解耦原则,在模块划分过程中统筹系统内部之间在功能层、原理层、行为层和结构层之间的多层次创新。以神经康复机械手为例进行设计实践,通过运动学和动力学分析,对FBS拓展模型的科学性和有效性进行验证。FBS拓展模型的映射求解策略,是对产品模块进行识别、划分和创建的一种方法,该方法自顶向下的构建了功构单元的分解聚合,实现了产品层次性模块配置。结果表明,FBS拓展模型有助于神经康复理疗设备设计阶段的机构组合创新,以及功能与结构之间的优化匹配,为神经康复理疗设备的设计研究提供了一定的理论基础和实践策略,能有效提升用户体验。
【Abstract】 For a series of problems such as inadequate knowledge expression in the design process of neurorehabilitation physiotherapy equipment,it is difficult to realize the product function building model.By combining the decomposition topology model of neurorehabilitation physiotherapy equipment with the modular design method,the overall model of neurorehabilitation equipment modular design of requirement(P)-function(F)-principle(W)-behavior(B)-structure(S)is proposed to realize the hierarchical module construction of neurorehabilitation physiotherapy equipment.A support system to support the modular configuration of neurorehabilitation physiotherapy devices was established.The system takes the design knowledge flow theory as the starting point to study the product module decomposition method driven by user requirements.The vertical iterative process of function-principle-behavior-structure evolution in the design decomposition process is analyzed,and the principles and methods of creating functional modules are explored,which leads to a product configuration design scheme for neurorehabilitation equipment.Based on this,a module decoupling principle is constructed for neurorehabilitation product systems,and multi-level innovations between the functional,principle,behavioral,and structural layers within the system are coordinated in the module division process.The mapping solution strategy of the FBS expansion model is a method to identify,divide and create product modules,which constructs the decomposition and aggregation of functional units from top to bottom and realizes the product hierarchical module configuration.The results show that the FBS expansion model is useful for the innovation of mechanism combination and the optimal matching between function and structure in the design stage of neurorehabilitation physical therapy equipment.
