The work aims to explore new paradigms of furniture design methods and manufacturing means in combination with rapidly developing digital technology. Under the influence of the "strong structure" design trend in digital design, several computer structure performance analysis tools developed by the graphical statics, such as Polyframe, 3DGS, Millipede3D and Ameba, etc., were used to integrate active structure form-finding into furniture design to explore the principles and methods of digital furniture design. With constantly updated structural analysis and generation tools, the traditional top-down designer-led design was transformed into a bottom-up generative new workflow, and a new vivid furniture design language and form was also created. With the rapid development of computer technology, computational design has gradually become one of the important methods of design. The new design process breaks the design limitations of standardized material selection and structural selection advocated by Bauhaus from the underlying logic, and then breaks through the international design style that gives priority to function in the traditional sense. At the same time, material optimization and mechanical optimization through computing technology better respond to energy conservation and environmental protection, forming a new era of form aesthetics and construction aesthetics of mass customization.
