German student patented "airbag" for a smartphone

The inventor inserts the retractable legs back into the case

Student from the German university Aalen Philipp Frenzel patented the case for the smartphone AD Case (AD means active damping), which protects the case in case of a fall. The device works very simply: the sensors work when dropped - and then the cover throws out four springy legs. The idea came to the guy when his own phone crashed while falling.

The legs are designed in such a way that they soften the fall at any angle (see the video under the cut).


Literally one day, a video with a “airbag” was distributed all over the Internet - and Frenzel woke up famous. He is now giving interviews to publications from all over the world. In an interview, a student admitted that he had been working on this case for four years . But it was worth it: for his invention, Philip received an award from the German Mechatronics Society.

Probably, the inventor has to solve a number of technical problems. For example, how to make so that the legs of the cover did not work in the pocket of a person when jumping or riding in the elevator.

In July, the guy plans to start collecting for the mass production of the gadget through Kickstarter. Obviously, it is necessary to do this quickly, until the wave of HYIP has declined.

I would like to believe that with the proliferation of such devices, the number of broken smartphones will decrease. But for some reason it seems that the owners of such covers will begin to actively test the novelty for durability and show it to friends, with an obvious outcome.
