Every bicycle needs a lock to keep it safe. But if you want to open the lock, you need to find your own bike first. It’s not so easy
because there are usually hundreds of various bicycles put tpgether and sometimes the insufficient light makes the situation
worse. So I designed the acousto-opical lock. When you take out the key and press button, the lock will make a brief sound and give out light. Thus, you can see your bike quickly and no need to pace up and down like a thief.
acousto - opical lock is a new tool which is based on ordinary steel ripe lock. The shape of main part is like
word “Y”, which is special and more elegant. This lock is of great benefit to students for finding their own bicycles during clras breaks or after self-study at night.
My aim of designing acousto - opical lock is to make people’s life eaiser and more convenient. With it’s help, people will love riding bikes and enjoy low carbon lives.
