But I know this was invented by a German student from Aalen Universitynamed Philip Frenzel. He has patented the AD (active dampening) phone case,which was built as a prototype. The case comes with sensors that can detect when the phone is in free-fall, which prompts the release of four springs that cause the phone to bounce when it hits the ground, dampening the impact. In fact, eight curled metal legs magically pop out from inside the case curling around the front and back of your phone. They absorb impact like springs (or an airbag, like the name suggests), as your phone bounces around without ever making contact with any surface.
The magic case
In many situations the protective case works, and especially when the cellphone drops on flat surfaces. All you need to do is fold each spring back into the case, and it’s ready to protect your phone from its next tumble. It’s not for sale yet but the inventor was awarded from the German Society of Mechatronics. No case will deliver the peace of mind we want. There’s always the chance a glass smartphone won’t survive certain accidents. A big problem is to be solved, aniway.
