Many traditional handicrafts face environmental, ecological, and heirloom decline. One of the most significant challenges in China's cultural inheritance and intangible cultural asset conservation projects is revitalizing traditional handicrafts. Exploring the heritage and creativity between modern design and traditional handicrafts from the standpoint of design might bring innovative ideas for preserving and developing traditional handcraft skills. The design procedures of traditional handicraft-based cultural items are explored in light of the clarification of traditional design strategies. Traditional handicrafts' culture and cultural design elements are deconstructed at three levels:utensils, techniques, and Taoism. Design methodologies change between tiers. This study proposes a Traditional-handicraft-based Cultural-product-design Model (TC Model). The deconstruction and rebuilding of explicit knowledge and tacit knowledge (in traditional handicraft culture) are explored from the perspective of the cultural knowledge transmission path.
