Digital video disc is commonly known as Digital Versetail disc. DVD is an electronic device that used to read data, music and audio visual. During installation and assembly process, there are few problems have been detected, such as broken tray cover. Tray cover is a plastic part in (DVD) named as Tray Cover. Hook is one of the parts of tray cover that always broken due to the loads applied by the operator which are not suitable for the assembly process. During the assembly process, the hook fails at 30N. A tray cover which is a part that is snap-fitted with the disc tray section of a Digital Versatile Disc (DVD) Player will be analyzed using Linear Static Analysis. The purpose of this study is to analyze and redesign the tray cover hook of a DVD player. The design of the tray cover is using snap-fit. The 3D modelled has been analyzed by using Finite Element Analysis (FEA) in Catia V5 software. The weakness of the current design will be improvised by redesign process. The mesh convergence test was done to define the optimum element size of whole part of the model. Stress analysis has been done based on the size element gained from the convergent test. Stress analysis done starts from 10N to 53N and until the von mises shows that it reached the yield strenght fail which is 68.4MPa. The result of stress analysis done obtained was fail at 56N. Then, analysis is being continued by adjusting the hook shape thickness. The hook thickness was being modified from 0.57mm to 1.4mm that has been tested where 1.1mm thickness size is the best where it can withstand 59.8N load. Next is the implementation of shape optimization for the hook where 0.5mm was added to the sharp corner and 3mm radius at the support rib and this optimization gain the best result where it withstand 63N of load.
