'Case' with function like 'air bag' function to prevent catastrophe in a smash dropping accident 'AD Case'

The accident "There was an accidental dropping smartphone and the screen cracked in a shaky ... ..." is common. In order to prevent such a sad event, a case having a function like an "air bag" of an automobile in which a key claw pops out and absorbs the impact when detecting a fall is invented.

The airbag function for the smart case named " Active Damping " can be confirmed with the following movie.

Engineering Student Designs a "Mobile Airbag" That Deploys When your device is Dropped

Schwäbische Erfindung rettet Handys


Philip Frenzel of Arend University in Germany, who invented "Active Damping Case (AD Case)". Friendsel, who had the experience of damaging the screen by dropping the iPhone, thought that he could manage to prevent the accident.

As a result, it was ...

A smart phone case that something like "horn" pops out from the four corners when it falls.

Thanks to the horn smartphones that dropped will bounce and prevent the display from being installed on the ground, greatly reducing the risk of damage to the display.

It was a warped plate reinforced with metal pieces like eight key claws that jumped out.

The plate detects the fall and jumps out.

The curled plate has flexibility enough to be easily bent by hand ......

It can be stored in the case again.

It is designed to be reusable, not disposable like "airbag" when it opens.

AD Case, Ms. Frizelle chose as the research theme of the university's master's thesis, has already obtained a patent.

The prototype was made with a 3D printer.

With this AD Case ......

Even in an unexpected fall accident, it seems to be injured.

Although it was Mr. Furezeru who had been damaged by dropping the iPhone, there was an idea that I do not want to ruin the design with a lot of trouble. From the beginning we began researching the case of improving safety without compromising the design and it seems that we focused on shock absorbing mechanism like "airbag". AD Case completed at the end of the research was the theme of the master's thesis, but it was awarded at the development contest Mechatronik-Preis 2018 sponsored by DGMev in Germany, and it won the Grand Prize exceptionally .

Mr. Furenzel said his father was an engineer and loved making things since he was small. From the T - shirt designed "AD Case" logo, you can see that it is aiming to commercialize AD Case.
