Abstract

In this study, the deformation and stress on each model was analyzed and the strength was compared with each other when the impacts on a total of four smart phone models was given. Models B and D with cases can be seen to have less deformation and stress than models A and C without cases. The models including the case have higher masses than the models without the case. So, the deformation and stress can be reduced by absorbing the impact force. In addition, the masses of models C and D are smaller than models A and B, but the stresses and deformations are seen to be smaller. If a case specialized for edge protection is chosen and designed when manufacturing a smart-phone in order to absorb the shock while weighing less, it is thought to improve the strength of the smart-phone and increase the durability. And it is seen that this study is adequate at the efficient design with durability of smart phone case practically and the aesthetic convergence of smart phone.

본 연구에서는 총 4가지 Model의 스마트폰들에 대하여 충격을 주었을 때, 각각의 모델들에 대한 변형량과 응력들을 해석하여 그 강도를 서로 비교하였다. 케이스를 장착한 경우의 모델들인 Model B와 Model D는 장착하지 않은 모델들인 Model A와 Model C에 비하여 변형량과 응력이 적은 것을 볼 수 있다. 케이스를 포함한 Model들이 케이스가 없는 Model들보다 질량이 더 많아지게 되어 충격력을 흡수함으로서 변형량과 응력을 감소시킬 수 있다. 또한 질량이 Model C와 Model D가 Model A와 Model B에 비하여 작지만 응력과 변형량이 더 작아짐을 보이고 있다. 스마트폰을 제작시에 무게가 적게 나가면서 충격을 흡수할 수 있도록 하기 위하여 모서리 보호에 특화되어 있는 케이스를 선택하여 설계한다면 스마트폰의 강도를 향상시켜 내구성을 증진할 수 있다고 사료된다. 또한 본 연구가 실제적으로 스마트폰 케이스의 내구성이 있는 효율적인 설계와 스마트 폰의 미적인 융합에 적합하여 보인다.
