When The Water Dispenser Is Controllable, Multi-Functional Shoes Can Be Changed At Any Time.

Walking into the teacher's office, I often hear the teacher sigh: the water in the drinking machine has been burning for another night, and I forgot to turn it off after work yesterday.

When I came home from school, I often heard my mother say, "hurry up and go to work, forget to turn off the water dispenser, and the water is boiled all morning."

Huang Jieqiang, a student in Huangpu middle school, is very careful in his observation of life. In his daily life, he found that drinking water boiled repeatedly is not only a waste of electricity, but also a bad health.

"If we add a device on the water dispenser to make the water dispenser automatically connect and disconnect at the predetermined time, will this problem not happen?"

Huang Jieqiang's idea of improving the water dispenser was supported by his parents and helped by the teacher. He began to look for information, and bought some auxiliary equipment to develop the time control device. After several tests, a simple and convenient time control device was produced.

In an old drinking fountain's power entrance, Huang Jieqiang added time control device: input and set the key part; display the output and action switch output part, show that the output part adopts LCD screen, the output part of the action switch adopts relay; the power supply part uses a button cell, that is, 1.5V; the arithmetic processing part adopts PCI single chip microcomputer to carry out logic operation and judgement, and make corresponding action.

After repeated debugging, the effect is good.

"Save electricity, do not produce toxic and harmful substances, set different time intervals, time switch, convenient for work and life, intelligent management."

Huang Jieqiang's tutor Yao Bilin said.

Another invention of Huang Jieqiang is closely related to himself.

"I love sports, basketball, football and running.

But I am a resident student. It's very annoying to change shoes in different sports environment. And buying different kinds of shoes is not economical and easy to carry. "

Huang Jieqiang said.

"If you can invent a multi-functional shoe, you can use it in different environments."

Huang Jieqiang began to ponder that he realized that multipurpose shoes could be adapted to different environments only by changing their soles.

Inspired by the cartridge cutters, Huang Jieqiang used a scrap aluminum alloy to design a sheath, which was fixed on the sole and could be installed with different types of soles.

It also made use of materials such as cardboard, screws and absorbent cotton to make two kinds of soles which can walk on the slippery road and slippery road.

Yao Bilin, the instructor, believes that the principle of using multi-purpose shoes is very simple and easy to operate. It also makes use of waste materials to solve the problems of adapting to different environments through changing the sole of shoes. In the course of using, it can also make shoes with different environmental conditions according to their needs, which is economical and practical.

"Because of the limited material, the tensile property is slightly worse. By improving the material, the practical performance can be better, and I will continue to improve it in the future."

Huang Jieqiang said.
