A few days ago, a German college student invented a mobile phone case named Adcase, which looks not much different from the protective case we saw on the Internet, but his ability is not as simple as it looks. It can automatically detect the drop of the mobile phone. At the moment of landing, eight small metal shrapnel will pop up at the four corners of the mobile phone case to help the mobile phone not directly touch the ground and prevent the mobile phone from being broken.
after each use, just fold up the phone case, and the shrapnel will be automatically taken back to the phone case for recycling. Is it convenient to use? This mobile phone case is inspired by the airbag of the car. As an automobile brand, Honda has also designed a mobile phone case with airbags, which will release six airbags when the mobile phone falls. The airbags will fully absorb the impact from the ground and protect the mobile phone more completely.
however, compared with the Adcase, the airbag of this mobile phone is too big and thick, and there is no clear explanation on how to plug the airbag back. It is not necessarily a bit far-fetched to say that it is a mobile phone case.
