Mobile Airbag is here : No More Cracked Phone Screen


A mechatronics engineering student from Germany has invented a “mobile airbag” that automatically comes into action when you drop your mobile phone, and hence protecting it from any kind of damage or harm.

Phillip Frenzel, a 25-year-old master’s student at Aalen University in Germany, came up with his idea after breaking his phone by throwing the jacket containing it over a banister. The impact caused the electronics inside the phone to break.

From then on, Frenzel began looking into developing a system to prevent dropped phones from breaking. Though we have huge stocks of big and bulky protective cases for smartphones available in the market but this guy(Frenzel) wanted something smaller and more advanced.


After four years of research and thinking, Frenzel created a “mobile airbag” that unfolds from the corners of a relatively-thin case when sensors detect that it’s in free fall.





When the phone is under free fall the dampers are pushed into their “airbag” position automatically with metal springs, and they help absorb the impact of the fall to protect a device’s screen and inner components. After being deployed, the dampers can be pushed back into the case, allowing it to be completely reusable.

Frenzel names his invention as AD Case i.e Active Damping Case.

The German Mechatronics Society was so impressed by Frenzel’s invention that it awarded him its national Mechatronics Prize for 2018. Frenzel has also since registered for a patent to protect his creation. He’s reportedly planning to commercialize the case starting with a Kickstarter crowdfunding campaign.
