The ‘Help Lock Doorknob’ by Haishan Deng is designed for ensuring an instant rescue if you stay in the room for too long a time. ‘Help Lock’ asks the users to pre-program a phone number and a time limit the first time you activate it. Once the time runs out, the doorknob will sound for 30 seconds to warn you to get out of the room.

Bike is one of the most eco-friendly vehicles in the world, but it is also very attractive to thieves. Maybe you can not protect your bike, but we should be more offensive to thieves. This lock is a good idea. When cut, colored liquid inside the entire length of the lock explodes forth unto the thief!

Maybe they will be scared, but there is another possibility, that is they will crush your bike rather than steal it.
