【摘要】 符号消费已成为一种新的消费趋势,用户认知产品创意的方式正在由过去的“实用功能的使用”转变为“符号意义建构和审美情感体验”。基于此,本文的研究目标是在解析产品符号及其用户认知特征的基础上,以全面的“用户-产品符号”之间的交互过程和交互方式为导向,构建基于产品符号认知的创新设计的过程模型,提出创新设计实用方法。结合符号系统理论和产品系统理论,解析了产品符号的物理属性、意图属性、时间属性和空间属性;描述了扩展的产品符号信息交流过程(工业设计师→草图→工程图→产品→商品→用品→用户感知→用户反应)、产品符号与用户之间的宏观信息交流方式和微观信息交流方式。引入认知心理学和美学理论,从审美印象、语义阐释、象征联系等3个方面剖析和总结了产品符号在语境、使用经验、产品心理模型、群体类型和使用条件等因素影响下的用户认知规律。阐释了产品符号用户认知过程中审美印象、语义阐释、象征联系之间的互动作用方式,揭示了认知反应与情感反应和行为反应之间的关系,即认知主导情感,情感影响认知,认知与行为交替进行。从“用户-产品符号”交互过程中多方交互关系出发,在格罗提出的FBS设计过程模型的基础上引入了新的设计变量——“认知”,构建了PFBCS设计过程模型及其扩展模型。根据不同的产品符号用户认知方式,提出了PFBCS设计过程模型的3个基本设计模式——PFBS、PFCS和PFBCS。对2009年红点产品概念设计获奖作品创新输出进行了统计分析,结果显示,主要从认知角度进行创新的占获奖作品总数的34.1%。基于扩展的PFBCS模型,提出了产品草图符号的认知涌现与未预见性发现驱动的创新设计方法。以“用户-产品符号”之间的交互关系为基础,构建了产品案例符号认知的基本语义网络模型,提出了案例符号认知语义网络模型扩散驱动的基本创新设计方法;进一步从时间属性和空间属性变换的角度,提出了行为过程细分扩散语义网络模型驱动的创新设计方法和使用情境类推扩散语义网络模型驱动的创新设计方法。进行了两组基于产品案例符号认知的创新设计实验,对结果的比较分析表明,案例符号的认知语义网络模型有助于设计师多角度地快速创新出符合预期设计意图的设计结果。更多还原

【Abstract】 Symbolic consumption has been a new current,therefore, the focus of users’cognition to innovative product has transferred from using of applied function to constructing of symbolic meanings and experiencing of aesthetic feelings. Based on this context, the purpose of this research is to construct creative product design process models and applied methods based on systematic analysis of product sign and its cognitive characters, these design process models and methods are oriented with comprehensive interaction between user and product sign.Combining with systematic theories of semiotics and product, this research explored the physical attribute, intentional attribute, temporal attribute and spatial attribute of product sign. Then, outlined the expanded communication process of product sign meaning, such as‘industrial designer→sketches→engineering drawing→product→commodity→appliance→user’s apperceive→user’s response’. Based on these, this research outlined the macro communication manner and the micro communication manner between user and product sign.Importing the theories of cognitive psychology and aesthetics, this research explored three kinds of users’cognitive responses to product sign, such as aesthetics impression, semantic interpretation and symbolic association. Moreover, this research analyzed five kinds of influences—context, literacy of use, mental models of product, population stereotype and conditions of sue, to these cognitive responses. Then, this research exposited the interactive manners among aesthetic impression, semantic interpretation and symbolic association, and the relations between cognitive response, affective response and behavioral response. The results suggest that cognition dominate affection, affection influence cognition, cognition alternate behavior.Orienting by interactive multi-relations of‘user-product sign’, basing on Gero’s FBS framework, this research constructed a basic creative product design process based on product sign recognition-PFBCS model, by importing a new design variable-Cognition. Mover, this research outlined the expended PFBCS framework, and offered three kind design processes of PFBCS model, such as PFBS, PFCS and PFBCS. Then, by statistic analyzing of creative designs awarded Red Dot Design Concept 2009, this research suggest that the awarded works creating from the perspective of cognition cover 34.1% of the total awarded living good designs.Based on the expended PFBCS framework, this research offered a creative design method driven by cognitive emergence and unexpected discoveries of sketches. Then, based on the interactive relations of‘user-product sign’, this research constructed the basic semantic network model of product case-sign cognition, and offered the basic creative design method driven by spreading of this semantic network model. Moreover, from the transforming perspective of temporal attribute and spatial attribute, this research offered a creative design method driven by spreading of semantic network model through behavior process subdividing, and a creative design method driven by spreading of semantic network model through usage scenarios analogying. Then, by two creative design experiments and statistic analysis of creating sketch-schemes, this research suggests that semantic network model of product case-sign cognition is very useful for designers to quickly create designs from multi-perspectives, and these designs can accord with the expected purpose.更多还原
