It was well known that standard cramp frame can only clamp a group of workpieces, without the ability to catch many groups of workpieces with related position constraint. To solve this problem, a design solution based on TRIZ theory as well as an inventive principle were proposed in this study. A bidirectural cramp frame with hyperbolic structure was designed, and it could clamp workpieces on both sides. Therefore, the application range and fields of this new kind cramp frame were expanded. Moreover, the bidirectural cramp frame was also analyzed and optimized using the finite element method. Finally, simulation results showed that both the bearing capacity of the bidirectural cramp frame and its stress distribution were improved.
