An ATM cassette is a device to hold and protect the bank notes during transport and within the machine. Dropping accidents of the ATM cassette occur during transport and thus reinforcement is needed since the cassette is damaged in a dropping-collision situation. Structural optimization improves the performance of the structure, and also the design techniques for strength-reinforcement. In this study, topology optimization is performed based on multiple loading conditions and the conditions are the impact loads which are imposed by several directions on surfaces. After topology optimization, the size and shape of reinforcement are optimized in detailed design. By changing the structure components that the structural components, the stress concentration is eliminated. As a result, an improved design flow of the ATM cassette is found.
