Yunzheng's idea is very simple. As a young man who was born in New China and grew up under the red flag, the most familiar means of transportation since childhood was...bicycles!
Yunzheng has always had a doubt in the past. He always thought that since the scientific and technological inventions in ancient China have reached a very high level and have been ahead of the world for many years, the four major inventions are examples. Like bicycles and tricycles, they only require human power to move through the chain.
The principle of transmission means of transportation should be similar to that of waterwheels, windmills and other equipment. The manufacturing process requirements are not high, but the ancient people just did not invent it. I don’t know why? Otherwise, this invention must have
It will be a historic invention that will have a significant role in promoting human civilization. The transportation convenience in ancient China will be greatly improved, and its impact on future generations will be inestimable.
Later, I saw a saying on a forum that it was because there were only two kinds of people in ancient China, those who rode cars and those who pushed carts. If a third kind of person appeared on a bicycle and ran by himself, he would definitely
I will be despised by the first two types of people. I have to say that although this sentence is a bit extreme, it is indeed in line with the reality of ancient China. Just like Yunzheng has always found brushing his teeth particularly interesting. In ancient times, although the equipment was not advanced, it was particularly good at tormenting people.
It makes sense to switch to a bicycle. People with status will definitely not be able to ride a bicycle by themselves, and people without status will probably not be able to get a bicycle. This is very embarrassing.
Fortunately, Yun Zheng is now considering using bicycles to improve logistics transportation capabilities, and does not need to consider the issue of this social trend. Social trends are no joke, especially in ancient China, where benevolence, justice, etiquette, wisdom and trust were at the forefront. "
Whoever wears the hat of "strange skills, Yin Qiao" on the head will be in great trouble. Zheng Xuan of the Eastern Han Dynasty said in the annotation of "Book of Rites and King System": "To make Yin sounds, strange clothes, strange skills, and strange weapons to attract suspicion, kill
!" And the most outstanding engineering and technical expert in the pre-Qin Dynasty, Gongshu Ban (the legendary Lu Ban), was listed as the first target of execution. Because Lu Ban used strange skills to make strange weapons, all dynasties in the past dynasties advocated the difference between justice and profit, Tao and weapons.
As the saying goes, "A gentleman is represented by righteousness, and a villain is represented by profit." Those who speak of righteousness and Tao are regarded as gentlemen, and those who speak of profit and tools are denounced as villains. This divides knowledge and knowledge products into high and low, advocates sitting down to talk about Tao, and despises technology and management.
, this value orientation has dominated China for thousands of years
Even the direct disciples of Confucius could not resist such a view. "Zigong... When he saw a man of ten feet, he would build a garden border, dig tunnels in and out, hold urns in his hands, and pour water out. However, he exerted too much force and saw that he had few achievements.
Gong said: "There is a tool here. It soaks hundreds of fields in one day. It uses very little force but sees a lot of work. Master, don't you want it?" The gardener looked up at it and said, "What can I do?" He said, "Hew the wood to make a machine.
The back is heavy and the front is light, and the water is like pumping out, and the number is like a soup. Its name is "槧". The person who worked for the garden made an angry expression and smiled and said: "I heard from my teacher that if there is a machine, there must be something to do, and if there is something to do, there must be something organic."
If the scheming heart is in the heart, then it will be pure and unprepared. If pure white is unprepared, the spirit will be born uncertainly. If the spirit is born uncertainly, it is not because I don’t know what the Tao contains. It is because I am ashamed and do not do anything.'
——Even Confucius’ direct disciples were defeated by this view, let alone others
Yun Zheng has traveled through time for more than half a year and has become basically familiar with the thinking of people of this era. If he, Marshal Yun, and Yun Tanhua were so free to invent a bicycle to ride on, they would definitely become a bad example of grotesque skills and ingenuity, and suffer a lot.
When thousands of people reviled and despised him, so when he came up with this idea, the first thing he considered was not whether a bicycle could be manufactured in this era, but whether it could be manufactured. If it were manufactured, would it bring any difficulties to him?
trouble, and whether such trouble can be avoided in other ways - having the same good idea but having to consider whether it can be done now is probably a tragedy that has not changed in China since ancient times, freedom, and a long way to go
There is no way to do it. Taking advantage of the trend of improving the transportation capacity of the army, Yun Zheng feels that if he can make bicycles and equip them with the army, it will actually improve the transportation capacity and save a lot of manpower and material resources. There should be enough
The reasons to withstand those objections are that saving manpower can be said to save people's power, and saving material resources can be said to save people's money. With these two things in mind, Marshal Yun's ability to use tiger skin as a banner is enough to win the prize.
Coming up with some great principles to keep your behavior consistent is not just "strange and clever", but also "benefits the country and the people, and contributes to the country."
After understanding this, Yun Zheng then considered whether the ancient bicycle invention was feasible.
In the original history, the bicycle was invented by Westerners. The origin is as follows: In 1790, there was a Frenchman named Sifulak. He especially liked to use his brain. One day, he was walking on a street in Paris because he had been there the day before.
It was raining, there was a lot of rainwater on the road, and it was very difficult to walk. Suddenly, a four-wheeled carriage rolled from behind. The street was relatively narrow, and the carriage was very wide. Xifulak ducked and dodged, but luckily he was not hit by the car.
He was still splashed with mud and rain. Others saw him, felt sorry for him, and even cursed him angrily. He wanted to call the carriage to stop, but after trying to reason, Sifulak murmured: "Stop shouting, stop shouting.
"Let them go." The carriage went far away, and he still stood blankly on the side of the road. He was thinking: The road is so narrow and there are so many pedestrians, why can't the structure of the carriage be changed? The carriage should be cut in half along the way.
, four wheels turned into two wheels at the front and back... When he thought about it, he started designing it when he got home. After repeated trials, the first "Trojan wheel" car for transportation was built in 1791. This car had two front and rear wheels.
The wooden wheel is connected to a crossbeam in the middle, and a bench is installed on it, like a toy. Because the car does not have a transmission chain, the car can move forward slowly only by the rider's feet pushing hard on the ground, and there are also wheels on the car.
There is no steering device, so it can only go straight without turning. After riding for a while, I will be exhausted and sweat profusely. The new things that have just appeared are always not so perfect. Sifulak is not discouraged. He continues to think of ways to improve it. Unfortunately, soon he
Died of illness
Then, in 1816, there was a forester named Drais in Germany. He walked from the woods to the east of the village to another woods to the west of the village every day. He did this every year. He thought: If a person sits in a car and walks,
Isn't it cool to stop and go and do whatever you want? Delais began to make a wooden wheeled bicycle, which looked similar to Sifulak's. However, a handlebar for controlling the direction was added to the front wheel, which could change the direction of travel, but the riding
When driving, you still need to use two feet to push the ground step by step to push the car forward. When Delais went out to test the bicycle, he was laughed at by many people along the way. Despite this, he still liked himself very much.
This "cute little pony" was created once when Delais was riding a bicycle and a carriage drove over. The coachman laughed at him and said that his car was slow, so he said to the coachman: "Do you believe it or not?"
Your carriage is faster." So the two of them made a bet that the distance was from the east of the village to the west of the village and back. As a result, Dries was faster than the coachman by more than an hour.
From then on, this design began to be taken seriously and was gradually improved. It developed into what it was later, and the design was basically finalized.
Yunzheng knew this situation, so he felt that it was wrong to say that we did not invent the bicycle because there were no steel wires, no chains, etc. It was mainly a matter of creativity. Of course, although many inventions in the world are accidental, they can
The failure to finally develop is a matter of the industrialization capabilities of the entire environment. With the national power of the Wei Dynasty, Yunzheng believes that as long as bicycles can be made and are actually effective, then "mass production" itself should not be a problem.
The problem now is that technically speaking, Yunzheng is a liberal arts student and is not as capable as other time travellers. Not to mention cars, cannons, and atomic bombs, just thinking about a bicycle is enough to give him a headache.
First of all, no one now believes that two wheels placed front and back can stand up on their own. Since the invention of wheels in ancient China, they have always been used side by side. For example, chariots of the Spring and Autumn Period and the Warring States Period suddenly have to have front and rear wheels.
It is estimated that only he, Marshal Yun, dares to ride the vehicle, but he is not particularly worried about this. At worst, he can just make it and demonstrate it to others.
The real big problem, the first one is the steering device. In the past, the saying on the forum was, why the Chinese have never invented a four-wheeled car, because our ancestors have never invented the steering mechanism. But fortunately, the structure of the bicycle is finally
It’s not very complicated. Based on Yunzheng’s experience of repairing cars many times in the past, I feel that it is very possible to imitate this device. Although it may feel a bit like a copycat product, now in Dawei, he can make it.
That is the inventor. In future generations, if he starts a manufacturing company, he will be one of those "first-class companies selling standards", so arrogant.
To say that the most difficult thing is probably the transmission devices such as chains and gears, the steel wires of bicycles, and the bearings of the transmission, which all require a relatively precise level of craftsmanship. The bearings of bicycles require the sliding friction to be as small as possible, so they need to be added
The steel balls use rolling friction instead of sliding friction like carriage bearings. The diameter of the steel balls and whether the bearing parts match each other require more precise calculations and precise metal processing tools. Yun Zheng has not yet fully understood the history of the Wei Dynasty.
The most real "industrial" strength, there are still some doubts, but he feels that even if the quality of these things in the Wei Dynasty is a little worse, they should still be manufactured, and as long as they can be manufactured, it will be easier to transport than now.
In addition, there are other devices such as brakes. Yun Zheng thinks it is not very difficult, so let’s talk about braking. The handbrake is probably a little more difficult, but you can install a simple foot brake, which is very easy.
After basically figuring out the problem of the bicycle, Yun Zheng was in a good mood. He immediately gave the order and continued on his way, but he was already thinking about how to make his first invention since time travel.
----------I finally rushed back to Changsha. My whole body is about to fall apart from exhaustion. In theory, I should be able to resume updating 5,000 words a day tomorrow. In addition, in the past few days, I will make up for the approximately 10,000 words I owed from the past few days.
