The paper delved into the strategy of extraction, design and modularized application of 3D design and decorative patterns of bronze drums in Guangxi, in order to integrate the culture of bronze drums into style of contemporary design and promote the inheritance and innovation of the bronze drum culture. First, typical samples of bronze drums in Guangxi were collected from museums, the internet and literature. Second, the paper summarized the fundamental rules and visual effect of the 3D design and decorative patterns of the samples so as to extract effective lines and typical patterns. Third, a modularized pattern database was built by redesigning the graphic elements with the design technique of deconstruction and reconstruction. Lastly, the patterns were presented as a lantern design case for the Zhuang Song Festival in Guangxi on March 3 on the Chinese lunar calendar.Through the modern design technique of summary-extraction- deconstruction-reconstruction , the 3D design and decorative patterns of the bronze drums were applied in contemporary design, a method that not only adds more cultural value to products, but also promotes the inheritance of bronze drum culture of Guangxi in daily application.
