Pupils win top prize at maker festival
    2017-10-25  08:53    Shenzhen Daily

As app-based bikes are taking cities by storm, more and more commuters choose to ride to work. However, safety concerns are also on the rise as accidents often happen.

Two young makers, Zhou Yichen and Yuan Hao from Liyuan Elementary School in Futian District, offered their solution by inventing an intelligent helmet for the safety of bike riders, and with it they won the first prize at the 2017 Shenzhen Student Maker Festival.

Before third grader Zhou and fourth grader Yuan put their hands to the helmet, they googled 20 road accidents related to bicycles and found that the most common causes of accidents are poor lighting conditions, making sudden turns without signaling and rear-end collisions.

In order to solve these problems, they hoped to make an intelligent helmet that could guarantee riders’ safety. And their dreams came true.

Fitted with tilt sensors and LED lights, the helmet they invented will light up as people lean forward while riding. Similarly, the turning signals will automatically light up as riders make turns; therefore, they will feel much safer when riding at night.

To avoid rear-end collisions, the ultrasonic sensor and buzzer enable the helmet to sound an alarm whenever there is an approaching vehicle behind.

Upon hearing the alarm, riders will slow down, thus reducing rear-end collision possibilities.

When riders get injured, they can press a button on the helmet which will send out an SOS signal. The GPS sensor on the helmet will help rescue workers locate the injured as quickly and precisely as possible.

As multifunctional as the helmet is, Zhou Yichen admitted that the helmet should continue to be improved. “The helmet is not perfect and we will keep improving it to make riders feel safe,” Zhou said, adding that there are too many sensors on the helmet which makes the helmet too heavy and the SOS button only allows close-distance help.

In the future, they will install a bluetooth answering function that will make other riding partners’ voice audible when calling for help.

In addition, they hope to install solar panels or a small fan on the helmet to save energy and incorporate a heath management feature that helps riders keep track of their heart rates and exercise frequency in real-time.
