The overall shape concept of the anti-drowning bracelet mainly includes the following aspects:

Safety: The shape design should ensure that the bracelet is stable and not easy to fall off when worn, and it can fit the wrist tightly even in water. The surface of the bracelet should be made of non-slip material to increase the grip and reduce the potential risk caused by slipping. The inflatable airbag part should be designed to be large enough and easy to deploy to ensure sufficient buoyancy in an emergency.

Practicality: The bracelet should be designed to be lightweight and easy to wear, without causing inconvenience to the user's daily activities. The trigger mechanism should be designed to be intuitive and easy to operate, and can be quickly activated even in stressful or panic situations. Considering the wrist sizes of different users, the bracelet should have a certain degree of adjustability to meet the needs of different people.
