Lu Ban was inspired by two things to invent the saw.

Which two things inspired Luban to invent the saw.

During the Spring and Autumn Period and the Warring States Period, there was a creative inventor named Lu Ban in my country. For more than 2,000 years, his name and stories about him have been passed down among the people, and later generations of civil and wood craftsmen have honored him as their ancestor.

Lu Ban was born about 507 B.C., his real surname is lost, and his name is Ban. Because he is a native of Lu, people call him Luban. Some books are written as public losers or for losers.

He was mainly engaged in carpentry. At that time, there was no good way to make trees flat and smooth planks. Lu Ban paid attention to observation in practice, imitated biological forms, and invented many woodworking tools, such as saws, planers, etc.

How did Luban invent the saw? Legend has it that once when he went into the mountains to cut down trees, he accidentally cut his hand by the leaves of a weed, he picked off the leaves and touched them gently, it turned out that there were sharp teeth on both sides of the leaves, and his hands were cut by these small teeth, and he also saw a big locust on a wild grass, and there were many small teeth arranged on the two large teeth, so it could quickly grind the leaves. Lu Ban was inspired by these two things.

He thought, if such a toothed tool could also cut through trees very quickly! So, after many experiments, he finally invented a sharp saw, which greatly improved the work efficiency.

Lu Ban stumbled upon the small fine teeth on the thatch, through careful observation, serious thinking, and so on to invent the saw blade, we should carefully observe the details in life, seriously think about the principle, to draw inferences from one another, and understand it thoroughly. At the same time, there is a connection between things, and everything will have some kind of connection.

Legend has it that one day, when Luban was going up the mountain, one accidentally slipped and was cut by a weed. Lu Ban took a closer look, and there were many small teeth on both sides of this leaf. He thought, wouldn't it be equally sharp if the tools used to cut wood were made jagged?

Thus, the saw was invented.

Labor creates wealth, and practice produces true knowledge. Labor is the only source of value creation, and the great inventions of ancient and modern China and foreign countries are all produced in the wisdom of labor. And Luban saws once again proved this great truth.

Be observant. Be good at gathering information. Elevate perceptual cognition to a space of rational cognition. Invention is people-oriented, in order to facilitate life and transform life, rather than the pursuit of luxury and nothingness.

Lu Ban stumbled upon the small fine teeth on the compound thatch, and made it through.

After careful observation, careful thinking, and so on to invent the saw blade, we should carefully observe the details in life, seriously think about the principle, and draw inferences from one case to another. At the same time, there is a connection between things, and everything will have some kind of connection.

The inspiration of the story is to pay more attention to the details around you in life, pay attention to many inconspicuous little things, and increase a lot of wisdom.

These things tell us that we must be good at observing the bits and pieces of life, many small details, all inventions and creations are people-oriented, as long as we seriously experience it, we can get sublimation from the depths of our hearts.

This story gave me a lot of inspiration and made me know to be a person with a heart for life, be good at observing life, and discover the mysteries in life.

Create** by observation and imagination. Lu Ban was inspired by the "leaves with sharp teeth" and "locusts that can grind the leaves with small teeth", and thought that "toothed tools can quickly cut trees", which led Lu Ban to invent the saw. The story of Luban's saw-making tells people that there is nothing difficult in the world, but only those who have a heart.

Observe carefully in life, think about small things, and think of different points of view from others. And when you put it into practice, you will gain something.

This story gave me a lot of bai

The revelation made me know that I want to be a person with a heart to live, be good at observing life, and discover the mysteries of life. In fact, many of the problems we encounter can be answered by what we have experienced before. Many things are related to life, and there are many answers that we want to know.

Don't read dead books, read dead books, learn to flexibly apply scientific knowledge, broaden your horizons, don't play dogmatically, give full play to your subjective imagination and observation, and make knowledge my own and used to solve the productive forces.

There is nothing difficult in the world, but I am afraid that Bai has a heart, as long as du

You usually pay attention to zhi, observe carefully, think hard, be willing to use your brain, invention is around you, and the sense of innovation will slowly develop.

Ban was a highly skilled craftsman in the Lu State during the Spring and Autumn Period. According to legend, once undertook to build a large palace, which required a lot of wood. At that time, there were no saws, not many trees could be cut in a day with an axe, and there was not enough wood.

The mountain is very steep, and when he climbed up, he cut his finger with a straw in one hand, and Lu Ban was very surprised.

On the way home, I would pick a thatch and take it home to study. When I looked left and right, I noticed that there were many small teeth on both sides of the thatch. At this time, Lu Ban remembered this incident, if we cut these trees into iron teeth like thatch, can't we see these trees?

So together with the blacksmith, they tried a piece of iron with teeth. Took it to see a tree, and it worked.

The leaves of the weeds scratched the hand of the Lai Luban, excited.

Since Luban's bai thinking, saws were born. Newton saw an apple from a tree.

Zhi fell He thought seriously and discovered the law of gravitation. Franklin discovered the law of conservation of electric charge with a kite experiment. Life is full of learning, as long as you dare to explore the unknown, you will definitely get unexpected gains.

A story is actually telling us that as long as we persevere. Discover the things around you and observe them carefully. Have a pair of eyes that see through beauty. You too can become a person like Luban. A common saying. There is nothing difficult in the world, but I am afraid of those who have a heart.

The clever Luban was mainly known for his craftsmanship and machine building, and although he also contributed to saws, he was not one of the most famous inventions. According to historical records, the clever Luban also invented many utensils and mechanical devices, such as carts, axes, waterwheels, and so on. Therefore,"The clever Luban invented the saw"This statement is not entirely true.

Hello, not true. The clever Luban invented the sawing machine, that is, the saw. A saw is a mechanical tool that can be used to cut wood, metal, plastic and other materials, and its working principle is to use the movement of the saw blade to make the object divided by friction.

The invention of the saw has greatly improved the efficiency of people processing wood, metal and other materials, and has made an important contribution to the civilization of people who are resistant to chaos.
