"It is this inverter that can reverse a voltage of 24 or 48 volts into a voltage of 220 volts, so as to drive the electric blanket for heating..."

While fiddling with the inverter in his hand
While explaining his own inventive ideas
Recently, the "73rd International Exhibition of Inventions in Nuremberg, Germany"
Good news
Invented by Wei Ziyang
"Intelligent wireless remote remote control heating electric vehicle windshield quilt"
He won a gold medal
A word that his mother inadvertently said inspired him
It is understood that the Nuremberg International Invention Exhibition in Germany is the world's longest exhibition history, the most stringent award selection, the most prestigious and the most influential international invention exhibition.
Talking about the original intention of this invention, Wei Ziyang said that it was because of a sentence that her mother inadvertently said. It was the winter of 2020 and it was cold. His mother took him to school in the morning and was always shivering with cold. Once, my mother inadvertently said, "How nice it would be if this windshield was an electric blanket, it wouldn't be so cold." Wei Ziyang fell into thinking: "The traditional windshield quilt is relatively thick, often interfere with normal driving operations when used, there are great safety hazards, if you use electric blankets to do the windshield, it will be very light, safer." ”
After this idea came to life, he began to look up information, draw sketches, buy parts... Eventually, the work was invented using electric blankets, voltage inverters, and the electric vehicle's own battery pack.
Take inspiration from life and fail again and again
In the process of invention, Wei Ziyang, who was only 12 years old at the time, encountered many difficulties. In the beginning, when trying to make a windshield, it is necessary to cut the electric blanket, and it is necessary to carefully avoid the heating tube inside, otherwise it will affect the heating function of the electric blanket. During the operation, Wei Ziyang would often accidentally cut the heating pipe, but he was never discouraged, and after each failure, he still patiently started again. "The prototype of this heated windshield was met with such a 'problem', I cut a total of 4 electric blankets before and after, which was successful!" Wei Ziyang said.
After continuous attempts, after finally "modifying" the electric blanket into a windshield quilt, Wei Ziyang thought of using the electric vehicle's own battery pack to heat and power the windshield. But a new problem has emerged, that is, the voltage of the electric vehicle battery is only 24 volts or 48 volts, and the wind shield is heated by a voltage of 220 volts, is there any device that can change the original voltage of the battery?
Wei Ziyang and his father consulted a lot of information on the Internet and finally found a voltage inverter that can reverse the voltage of 24 or 48 volts into a voltage of 220 volts.
When the inverter was installed and the windshield was successfully heated, Wei Ziyang was very excited. After he confidently installed it for his mother, he found that it took about 10 minutes for the electric blanket to reach 37 ° C, waiting for the heating to be completed, and his mother had already sent him to school, which could not play a warm role at all.
After Wei Ziyang discovered this pain point, he began to check the information non-stop, but he never found a solution. "I bought 5 or 6 Bluetooth switches on the Internet before and after, all of which could not be used, and suddenly one day, I found the wireless Bluetooth remote control function of Tmall Genie at home, so I tried to connect its control switch with the power supply of the electric blanket and the switch of the inverter, and controlled it through the mobile phone mini program, and I did not expect to succeed!" Wei Ziyang said excitedly.
The judges marveled at the innovative ability of the Chinese students
In February 2021, after about 3 months of hard work, 12-year-old Wei Ziyang successfully completed his first invention in his life, and after about 2 months of debugging, this "new windshield" was finally officially "put into use" in his home.
In early October 2021, Wei Ziyang registered for the 73rd International Exhibition of Inventions in Nuremberg, Germany. His work stood out and eventually won the gold medal. The comments given by the jury of the competition were: "Let the world marvel at the innovation ability of Chinese students, and fully demonstrate China's intelligent manufacturing!" ”
From "military fan" to "inventor"
"Since he was a child, he likes to disassemble toys, household appliances, etc., and likes to watch invention stories. He was also a 'military fan', with more than 100 toy guns, all of which he had basically dismantled. Wei Ziyang's father Wei Lu said, "We also consciously cultivate children's interests and hobbies in this regard, buy a lot of invention and creation books, and encourage children to be active and active in thinking." ”
In the future, Wei Ziyang hopes to invent more works and participate in more invention competitions.
Congratulations to Wei Ziyang!
