This paper presents the design of a gold bead chain machine. The gold bead chain machine is designed for automatic gold chain process. Firstly, the gold bead chain’ structure and the design requirement are discussed. Then, based on the modern design methodology, the authors design the gold bead chain machine by using black-box to get the morphological matrix of the function and the function unit solutions. Lastly, the authors analyze and choose the optimal scheme and make an integration of the function unit solutions.
