The simplest invention

In human history, every invention has promoted social progress and improved human life, which is commendable and commendable.

Do you know what the simplest invention is?

As we all know, the appearance of the round pencil is an epoch-making product, which greatly facilitates people's recording and use, and has low cost and rapid popularization.

A pencil user will occasionally find that a round pencil will automatically roll when placed on a flat table, and it is easy to fall and break the refill. He designed the round pencil into a hexagon, which overcame the shortcoming of easy rolling. The man immediately applied for a patent, and then authorized the pencil manufacturer to produce hexagonal pencils, which earned a lot of money.

Simple. Turning a circle into a hexagon is an invention!

However, this invention is indeed unprecedented. Although this patented technology has already passed the protection period and can be used for free, its influence is still extensive and far-reaching.

Everyone can produce excellent ideas at any time, but few people turn inspiration into designs and products. Therefore, ideas are always just ideas and cannot be turned into inventions.

The simple invention is unprecedented and worthy of praise and promotion.

There are tens of thousands of patent inventions related to pencils in the world, which is really unimaginable!
