中文摘要：

为寻求对设计理论基础体系的扩展,总结了现有＂功能＂概念的涵义,从概念对象系统层级及范围的角度将＂功能＂概念内涵统一至＂意图行为＂。引入Affordance作为现实域的基本概念,并对现有Affordance的不同涵义进行了总结辨析,将概念内涵统一至＂行为可能＂。通过对比联系理清后的＂功能＂和Affordance概念,阐明了两者间的互补和协同关系。基于两者的协同使用建立了能涵盖意图域和现实域的扩展后的设计理论基础体系,该体系涵盖更多设计活动参与主体,明晰设计过程的所有系统层级,适用于广义产品,并通过意图域与现实域间的反馈核查迭代,为设计活动的动态演进建立结构化过程的理论基础。

英文摘要：

To expend the basis system of product design theory,the concept of existing was summarized,and the connotation of＂function＂was unified into＂intended behavior＂from a view of system level and scope of conceptual object.Affordance was adopted as the basic concept in physical realm,and the different meanings of existing Affordance was analyzed which unified function connotation into＂behavior possibility＂.Through comparing and correlating the cleared concepts of function and Affordance,the complementary and cooperative relationship between these two concepts was clarified.Based on the coordination of function and Affordance,an expanded design theory basis system which could cover both intent realm and physical realm was constructed.More participants of design activity were involved in this theory system,and all system levels in design process were cleared,which was suited to generalized product.Through the feedback,check and iteration path between intent realm and physical realm,the theoretical basis of structured process for dynamic evolution of design activity was constructed.
