AI Technical Summary
Existing self-inflating life rings are difficult to spot quickly in dimly lit environments, prolonging rescue time. They are also prone to breakage due to excessive air pressure when over-inflated or during drifting, posing a safety hazard.
A self-inflating, throwable lifebuoy was designed, equipped with a positioning indicator and a safety depressurization component. The positioning indicator uses a waterproof LED light to emit a clear light signal in dim environments, helping people who have fallen into the water to quickly locate the lifebuoy. The safety depressurization component automatically depressurizes when the air pressure is too high to prevent damage.
It enables rapid location of people who have fallen into the water in dimly lit environments, reducing rescue time and ensuring the safety and stability of the lifebuoy during use.
