The Bauhaus has inspired creativity through fundamental courses of design theories and deeply influenced design of architectures, products, spaces, stages, furniture, fashion, and graphics around the world in the past 100 years. When the Taiwanese government promoted the policies regarding subcontract works and trading, the furniture industry was able to get orders from large furniture companies in advanced countries and thus learned Bauhaus’ modern design and manufacturing technologies from the subcontract works. Nowadays, in the face of global market changes and new industrial trends, these subcontract work experiences in the past have become the nutrition to create a self-owned brand. This study aimed to explore the influences of the Bauhaus style on furniture design in Taiwan, adopting the mixed methods approach with both quantitative and qualitative research methods. Through the qualitative analyses, the constructs, namely “human-centered spirit, humanistic spirit, furniture design”, and the essential items, namely “function, technology, model, color, and material’’ were extracted to further develop a scale for the invited scholars and experts to evaluate the products. The PLS method was adopted to obtain the weights. It was found that 2 of the 6 “TW.U.C.M.” products were designed in the Bauhaus style and the results were highly significant. Then further analyses were conducted to explore the performances of the products on the constructs and the items. The outputs of this study include the “constructs of the influences of the Bauhaus style on furniture design”, the “constructs of the influences of the Bauhaus style on furniture designs of ‘TW.U.C.M.”, and the “influences of the Bauhaus style on furniture design of scale”. The rich and complex of the Bauhaus style was converted into practical strategies and tools of management and evaluation for furniture or product design, and can serve as references for theoretical research and industrial practices.
