In this study, the shape design optimization of a refrigerator door hinge stopper was performed to reduce thediscrepancy in the opening forces of the left and right doors of a double-door refrigerator. A finite elementmodel was constructed and analyzed by quasi-static analyses to evaluate the structural performance of the doorhinge stopper. The reaction moment calculated at the hinge axis was used as a measure of the door opening andclosing forces. The design objective is to increase the door opening force by 50% while maintaining the doorclosing force and the maximum stress calculated in the body of the hinge stopper at the current level. A newdesign concept with a contacting slot was proposed to decouple the door closing and opening forces. Shapeoptimization was performed to determine the dimensions of the new design of the hinge stopper, and the ribpattern was determined by topological optimization to further increase the door opening force. It was observedthat the new design met all design requirements.
