What national patents have primary school students obtained for developing 3D printed Luban locks?

A few days ago, Yang Jialin, Chou He Jia and Cheng Kexin, graduates of Chaoyang Experimental Primary School, received a heavy opening ceremony: their classroom learning work-3D printing Luban Lock, which was completed in the fourth grade of primary school, won the design patent certificate issued by China National Intellectual Property Administration.

It is understood that Chaoyang Experimental Primary School began to introduce 3D printers from 20 14 and set up a comprehensive practical course of 3D printing. In class, students spontaneously form groups to study 3D printed educational toys.

As four traditional educational toys in China and an important part of traditional culture in China, Lubansuo has always been loved by students. However, the manufacturing process of six Luban locks on the market now is rather troublesome, and the splicing steps are complicated, so it is almost impossible to complete the splicing without schematic diagram.

Qiu Hejia, a design member, said, "We found that the' Luban Lock' actually used the tenon-mortise principle, and it was migrated and deduced through the 16 block structure of the ancient Luban Lock, and it was reduced to six pieces now, of which four pieces were relatively pieced together and two pieces were fixed. It can make younger students easier to get started and more interested in playing. "
