Lu Ban invented many things. According to many ancient books, he invented many woodworking tools used by carpenters. Like a carpenter's ruler, it's called Lu Banchi. Another example is Mo Dou, umbrella, saw, planer and drill. Legends are all invented by Lu Ban.
The invention of these woodworking tools liberated the craftsmen at that time from the original heavy labor, and the labor efficiency was doubled, and the civil technology took on a brand-new look. It contains the original knowledge of physics.
Lu Ban is also an outstanding mechanical inventor. The lock he made, the mechanism is inside, and there is no trace outside. It can only be opened with a matching key.
There is such a record in the book Mozi: "The loser cuts bamboo and wood, thinking it is a magpie, and flies away three days later." In other words, the wooden bird made by Luban can fly high in the air by the wind and not land for three days. There is no denying that Lu Ban is the Depth Charge of primitive aviation science.
Luban also improved the structure of vehicles and made motorized wooden chariots and horses. This kind of wooden chariots and horses is driven by Woodenhead, equipped with mechanism, and can walk automatically.
Many scientific and technological inventors in later generations, such as Ma Jun in the Three Kingdoms period, Qu Chun in the Jin Dynasty, Ma in the Northern Qi Dynasty and Ma in the Tang Dynasty, were all influenced by this legend and developed in this direction one after another.
In weapons manufacturing, Lu Ban once made siege equipment for Chu and played a great role in the war. Later, under the influence of Mozi, he stopped making such war tools and devoted himself to inventions in production and life to benefit the working people.
origin
Lu Ban was a native of Lu in the Spring and Autumn Period and a famous craftsman in history. The woodworking industry is founded by Bailuban.
When carpenters make tables, doors, windows and furniture, they will use a ruler one foot, four inches and one quarter long. Rulers not only have dimensions, but also words to ward off evil spirits and take good luck. People call it Lu Banchi, also called secretary.
It is said that Lu Ban and Wen Gong are both famous craftsmen, but Lu Ban is always superior, which makes Wen Gong very jealous.
Once, these two men were ordered to lead their people to build a palace. While people were not looking, Jin Wengong sawed the ruler that Lu Ban used to measure the length short and changed it from one and a half feet to one and a half inches. When Lu Ban's disciples used this ruler to cut wood, they found that the length was wrong. Time was short and materials were exhausted. Lu Ban used his quick wits to replace the insufficient length with a stone pier, and the result was more solid and beautiful. The king was very satisfied. When people asked him how he had such a whimsical idea, Lu Ban smiled and replied, relying on the ruler given by Wen Gong! From then on, Wen Gong was convinced. This ruler has been handed down to this day.
That is, the woodworking ruler, also known as the "square", is mainly used to check whether the planed plates, purlins and structures are vertical and whether the edges are at right angles.
Soon after, Lubanchi appeared, Ding Lan ruler was integrated, and then inches and centimeters were integrated. It is an important tool for measurement and calibration. Because of its special function, it is most widely displayed in geomantic culture and architectural culture. When building a house and making furniture, we should use this ruler to measure the height, width and length from the whole to each part, so as to get the scales related to Geely and avoid the scales related to disasters, so as to adapt to the psychology of praying for peace and auspiciousness.
