The purpose of this paper is to synthesize the structure of metal cans squeezing devices with eight links based on the methodology of creative design. First, the design requirements and design constraints are specified based on the characteristic of existing squeezing devices. Then, specializing with respect to (8, 10) generalized chains, the atlas of specialized feasible chain is generated. Furthermore, the atlas of new design is obtained through the process of particularization. Finally, the atlas of new design with single toggle effect is also synthesized. In addition, the feasibility of the design is verified by a prototype machine testing.
