People have the tendency to drop and break their smartphones consistently, and an engineering student has come up with a solution that will save everyone from the hassle of money, time and stress put into their phones. Philip Frenzel has designed and invented the mobile airbag - which is a case that detects when your phone is falling and releases prongs to guard against the impact.
This idea came to him when his own iPhone broke due to a fall. The idea took four years to perfect after many failed experiments involving foam and other substances. Frenzel eventually came up with the idea of using mechatronics to support the design of his case. (Mechatronics is a multidisciplinary field that combines mechanical engineering, electronics, computer engineering, telecommunications engineering, systems engineering and control engineering.)
He used sensors inside the case to detect when the phone is falling and used eight springs attached to plastic legs that release to cushion and save the phone from ground-breaking impact.
Frenzel has called his invention the ADCase - which is short for Active Dampening. It is still a prototype, but Frenzel has launched a business website for the product with his business partner that will help to promote the product on Kickstarter.
The case attaches itself to the back of the phone with its legs set into the small box that can be mistaken for a battery. When it's activated by free-fall, the case extends its legs forward and backward on both sides, allowing the phone's surface to be protected from the fall. After the phone has been recovered from its fall, the legs can by pushed back into the box by pressing and folding them back. The ADCase also comes with an extra battery.
The case is only 4.9mm thick, but its legs have a safe cm buffer when it's fully extended out. It also comes out with several models compatible with all iPhone versions.
I wonder if this will cut anyone accidentally. We shall see.
The ADCase can be used on iPhones and is compatible with many other versions. (Video Credit: ADCase)
