This study analyzed the effect of reinforcement ribs on the structural strength of a partition wall in a ready-to-serve fish cooling box using the Finite Element Method (FEM). The partition functioned to separate the fish and ice compartments but experienced excessive stress during handling. Three rib configurations, plus (+), cross (x), and oval (o), were designed on a 2 mm thick PET partition and tested under a 500 N load. The main parameters evaluated were Von Mises stress, displacement, and total weight. The results showed that ribs reduced stress by up to 81% and displacement by 85%, with only a 15–23% weight increase. The Weighted Sum Method identified the plus-shaped rib as the optimal design, achieving 12.99 MPa of stress, 0.682 mm of displacement, and 1.08 kg of weight. In conclusion, the plus-shaped rib provided the best structural efficiency and met the safety criteria below the PET yield strength. These findings indicate that the proper rib geometry can significantly enhance stiffness, durability, and overall mechanical performance while maintaining weight efficiency for practical industrial applications and supporting future design development of thermoplastic-based cooling systems.
