The difference between Gao Zhe and Lego

The difference between Gao Zhe and Lego is the feel.

In terms of feel, Lego is slightly better. One small particle in Gao Zhe is hard to find, and the other is too hard. In addition to the basic operation of diamond finger, it is better to knock with a small hammer, which will save labor. Except for the large number of blocks, it is basically a disadvantage.

The quality of Lego bricks mainly refers to the accuracy and feel of parts. At present, Lego's building blocks have the highest accuracy and the best feel. The splicing strength of the parts is just right.

Lego building block structure

Most Lego bricks have two basic components: the upper protrusion and the inner hole. The bump of the building block is slightly larger than the distance between the hole and the side wall. When you squeeze the building blocks together, the protrusions will push the side walls outward and push the holes inward.

This material is elastic and can keep its original shape, so the side walls and holes will squeeze the protrusions. Friction also plays a role, which prevents two building blocks from sliding apart. The projection hole engagement system uses the interference fit principle and does not use the tight connection between two parts of other fasteners based on friction.
