How could a mobile airbag prevent your phone from damage?

A German engineering student has invented a ‘Mobile Airbag’ which can save your phones from accidental drops. An ingenious new case aims to protect your smartphone without adding bulk to it, by deploying a sort of a mobile airbag when necessary.

Here is how this active damping phone case mobile airbag works and how can it revolutionize the protective case industry.

How could a mobile airbag prevent your phone from damage?

If you’ve never dropped your smartphone, then guess what it’s going to happen sooner or later?

We already have several case options in the market that can protect mobile devices from harm, such as cracks, scraps, water damage, and more. But usually, they come at a price apart from adding more bulk to the handsets that we have to carry around in our pockets.

Most of us already know about car airbags and how useful they can be in protecting our lives at the time of an accident, what if someone tells you that there’s a new invention that can save your smartphone from those accidental drops.

Accidents are prone to happen and when it comes to your smartphone, it doesn’t matter how cautious you are, there is always a possibility that you might end up dropping it. A good case and a screen protector might protect you from the worst of the damage, but those things can only do so much. That’s where this inventive “Mobile Airbag” comes into play.

Why an ‘active damping’ phone case design has been prescribed?

Smartphones have come a long way and they can do all sorts of things besides just calling and texting, but all of those advanced features come at a price and in case of damage, the repairs can be quite expensive as well.

For this reason, many choose to buy protective cases that shield the device from accidental drops or bumps. However, such cases typically make the smartphone thicker and bulkier, the tougher the case, the bulkier it gets.

However, a solution called AD (active damping) phone case, which has been registered for a patent, can detect when your handset is in a free fall. It then releases springs to make the phone bounces on the surface, damping the impact.

Rather than padding the phone with a bulky suit, this case simply transforms only when necessary. If the phone is not in danger, the case will not compromise its aesthetics.

Where from the idea came?

Philip Frenzel, a 25-year-old student from Aalen University in Germany, the inventor of this ‘Mobile Airbag’, came up with the idea after he broke his own smartphone. He then started developing a system in order to ensure that a smartphone is safe from any damage even after being dropped. Instead of being big and bulky, Frenzel wanted his case to be smaller and advanced. After a research of four years and testing several designs, he finally invented a case which has inbuilt sensors to detect whenever a smartphone is in free-fall.

This video is posted by public broadcaster Sudwestrundfunk, in which Frenzel demonstrates how the invention works…

How the active smartphone case Mobile Airbag works?

# This smart case is equipped with sensors that detect when the phone is free falling and trigger a protection mechanism.

# More specifically, the case has springs on all four corners, with eight metal curls that will stop the phone from hitting the ground.

# These fins lie inside the case when the smartphone is safe, but when it’s free falling they spring and curl up to protect all edges of the device.

# The curled-up fins absorb the shock and significantly soften the blow when dropping the device.

# When it’s over, you can just fold the springs back into the case, where they will stay neatly folded until the next accident.

Hopefully, the sensors are fine-tuned enough as not to deploy when the phone is in a pocket or a backpack, even if the person is running or making sudden movements.

# As per the video, the AD Case adds minimal weight to a phone while offering significant protection against drop-shock. 

# One notable advantage over airbag systems is that the device can be quickly reset by pushing the prongs back inside the case.

Notably

Notably, the mobile airbag or AD case is currently not available for purchase yet. However, Frenzel has acquired a patent and also received an award from the German Society of Mechatronics for his invention.
