目的在中国式现代化进程中,文化交流与融合日益紧密。通过研究中、西方工业设计史,探讨如何将西方理论、方法与中国走向国际化工业设计相融合,并为传承中华文明获得更高层次提升与创新提供导引式指导。方法采用了比较分析法、案例法、文献法,中国工业设计史主流思想受到“制器尚象”“天人合一”“祈福禳灾”等中华优秀传统文化理论的影响。同时,受到“西学东渐”西方工业设计理论、方法的影响,中国本土文化在审美观念、艺术创作范式和设计取向等方面出现一定偏离,应在吸收西方设计史中经典的STS、ANT脚本和驯化理论与方法的基础上,提供科学、先进的方法,正确引导中国工业设计走向传承中华经典传统文化和新时代的创新。结果从设计学视角总结了中国式现代化进程中工业设计理论与方法的识变,传承本土工业设计产品外观形式的应变和产品功能升级的求变。对中、西工业设计融合的创新路径提出了“生命意境”的设计内涵、“生产效率”的设计技术、“生活传统”的人文关怀等具象性设计策略。结论中国工业设计应从中、西方工业设计理论和方法比较中,吸取各自精华,并从“识变、应变、求变”策略中继承中国工业设计蕴含的优秀传统文化内涵,融会贯通地吸收西方工业设计中的科学理论与方法,为“中国工业设计”构建强有力文化自信与文化创新能力提供一定支撑,最终推动中国设计走向世界,展现中国的设计能力。
