One of the most frequent and major troubles that happen with smartphones is broken screens. Owners of devices often try to protect them with protective glasses or bumpers, however, these devices can not always protect the gadget from hitting a hard surface in case of accidental fall. Recently, Philip Frenzel, an engineer from the German University of Alain, came up with an original case that protects smartphones even from extreme falls. This is a kind of airbag for mobile gadgets. The sensors of the accessory react to the free fall of the device and instantly special flexible legs that spring from any hard surface extend to both sides of the corners of the case. It is curious that until the protection works, you cannot understand how unique it is by the appearance of the cover. The device will become reusable. After the mechanism of the case works and protects the smartphone, the springy legs easily fold into their original position. True, not all the details of the functioning of the news are still clear. It’s not clear, let’s say what will happen if the mobile device falls in a handbag. And whether the novelty is protected from triggering in your pocket. The Mechatronics Society from Germany has already evaluated the invention by awarding it its highest award, and the author sent an application for a patent for the original case. In addition, Frenzel intends to launch a project at the Kickstarter crowdfunding site to raise funds for the production of his invention.
