Nowadays, mobile phone protective cases are endless, and they are becoming more and more fashionable and beautiful. It is still possible to decorate the mobile phone and prevent it from getting stained, but when the mobile phone falls to the ground, it is still possible to count on the mobile phone. There is a question mark as to whether the shell protects your favorite phone. This careless German guy is a frequent user who often drops his mobile phone. He is deeply troubled by the broken screen. In desperation, he designed a mobile phone case with a safety spring, AD Case.
The moment the phone falls to the ground, four claws will pop out to protect the phone from impact. AD Case uses active damping technology. The two-layer design is about 4.9mm thick. He said that the design was inspired by airbags, but it does not use inflatable air cushions to protect mobile phones.
Instead, it uses built-in sensors and 8 hook-shaped safety springs. When the phone case detects that the phone is falling freely and rapidly, four springs hidden in the phone case The eight spring claws on the corner will pop up automatically instantly. No matter which angle it falls, the spring will hit the ground first, and the buffering effect of the spring can protect the phone well.
After the 8 claws pop out, they can be retracted manually. However, there are electronic components in the phone case and they need to be charged before they can be used. As the saying goes, you can't have your cake and eat it too. If you want to better protect your phone, you should take the trouble to charge it.
