Active Damping Phone Cases – A New Invention!

Phones are often prone to damage due to sheer negligence of the humans. We all tend to have butter fingers and thus your phones would slip through your fingers and the next moment before you realise, your phone either has scratches or it’s completely broken. A person would surely have a mini heart failure.

In order to avoid this, many came up with protective cases but they tend to ruin the look of your phone. So what’s the solution?

The Solution – AD Smartphone Case

25 year old Philip Frenzel, who is a master’s student (mechatronics engineering) at the Aalen University in Germany, faced a similar problem. He broke the electronics inside his phone when he threw his jacket (which contained the phone) over a banister.

He wanted to avoid this breakage in future and hence looked for various options in order to save his phone. Frenzel came across many bulky protective cases which served the purpose but he required something compact and advanced.

He spent four years in research and later developed a very fascinating way to protect his smartphone through “Mobile Airbags”. He named his invention as AD (Active Damping) Smartphone case.

How does the AD phone case work?

The AD smartphone case works on the principle of sensors which detect your phone’s free fall. The case basically consists of 8 hook like springs which have b. These springs deploy quite automatically if and when your phone is in free fall. It is relatively a thin case wherein the airbags unfold from the corners of the case.


The metal springs/dampers bounces on the ground when it’s prompted to a free fall. This basically absorbs the impact of the fall which thus protects your smartphone from any breakage or even scratches. Also, these can be reused, i.e. once they are being deployed, the dampers can be inserted back into the phone case.

This AD smartphone case doesn’t add bulkiness to your smartphone, hence doesn’t ruin the look of your mobile phone. This invention was appreciated by the German Mechatronics Society. They awarded Frenzel with the National Mechatronics Prize 2018.

The AD case does have few minor problems, such as –

  • It doesn’t completely protect your smartphone from accidents on uneven surfaces such as an irregular shaped object like rocks.
  • The case is also said to be popping open if it’s in your pocket.

This is indeed just a prototype and hence Frenzel would definitely give in his best to overcome these problems.

Frenzel has planned to commercialize his invention through a crowd-funding campaign. Although he has registered his invention for a patent in order to protect his idea.1
