Para qué sirve
The existing protective measures for pedestrians on the road are limited, making it difficult to ensure their safety. There is an urgent need for more effective protective measures to reduce risks.
Qué te inspiró
I first discovered this problem from an accident involving someone around me. This is an old man with poor ears, so when a car that was described by others as not fast came from his blind spot, he did not come or avoid it. The perpetrator also did not notice him. This accident made me realize that nowadays pedestrians can only rely on being noticed by the driver. Once the driver is unable to detect pedestrians in a timely manner, they will fall into a passive and helpless situation. If there were such a device that could give pedestrians more initiative in similar situations, perhaps many accidents could be reduced.
Cómo funciona
This system consists of a belt and two wristbands. The belt integrates core components such as mini LiDAR, microprocessor, Bluetooth module, and lithium battery inside. Among them, mini LiDAR is used as the core sensor, which can reach 192 lines of ultra-high beam and 120 °× 90 ° ultra wide field of view, accurately capturing vehicles in the wearer's blind spot. The microprocessor is responsible for data processing and algorithm operation. Based on the object distance, speed, direction of motion and other data obtained by the laser radar, it quickly evaluates the threat of incoming vehicles through built-in AI algorithms. The two matching wristbands and belts achieve real-time communication through low-power Bluetooth. When a threatening incoming vehicle is detected, the system will alert the driver with corresponding red flashing lights and alarms on the belt and wristband based on the detected direction of the incoming vehicle.
Proceso de diseño
At first, I just planned to create a warning system that would send signals to pedestrians, so that they could notice threats approaching from unknown places and react accordingly. However, after explaining this design to my teacher, he gave his opinion that it is unreasonable to let the wearer of the device react, and at the same time, when faced with threats, people often move slower, so such reminders seem to have little effect. After absorbing the teacher's advice, I have come up with the idea of sending signals to those threat sources to make them aware of pedestrians ahead. This design would be more reasonable and reliable.
Qué lo hace diferente
Compared to the current situation where pedestrians can only make more accurate judgments about incoming vehicles within their line of sight through visual perception, and make fuzzy judgments about vehicles in blind spots through auditory and other senses, this device can more accurately identify things in blind spots through sensors. Compared to the current situation where vehicles rely on drivers to detect pedestrians ahead, this device can actively send signals to oncoming vehicles to serve as a warning, avoiding drivers from not being aware of pedestrians ahead due to certain reasons such as driving or blind spots in the vehicle's field of view.
Planes para el futuro
This device can provide close protection for people who lack self-protection ability, reduce the risk of accidents, and make family members feel more at ease. At the same time, for other groups of people who often go outdoors, this device can help them detect incoming vehicles and issue warnings in a timely manner, ensuring their movement while ensuring personal safety. With the gradual improvement of people's safety awareness and the continuous development of the smart wearable device market, this device is expected to become a popular choice for pedestrian travel safety protection, with huge market potential
