Abstract：

Under the theoretical framework of posthumanism, this study, from the interdisciplinary perspectives of technological phenomenology, actor-network theory, and semiotic analysis, reveals the paradigm shift of smart product design from functional adaptation to emotional symbiosis, based on the theoretical framework of posthumanism and combined with technological phenomenology and actor-network theory. Through semiotic analysis, it demonstrates that smart products, as cultural interfaces, need to reconstruct their symbolic semantics. The SET-PMC model and emotional computing technology promote the symbiosis between technological embodiment and cultural metaphor. The study finds that smart design faces the "humanization paradox": generative AI leads to the transfer of design rights, and the data-driven logic triggers algorithmic biases and imbalances in digital equity. The study proposes to construct a participatory ethical framework and a recursive symbolic system, emphasizing that smart products should break through anthropocentrism and establish symbiotic aesthetic criteria from the perspective of non-human actors. Finally, the methodology of "ecological whole system design" is formed to achieve dynamic balance among the three networks of technology, culture, and nature, providing a specific practical path for technological critique theories.
