Otaku Engineer in Great Tang Dynasty Chapter 52: 2 engineering dogs
"Xiaoxuan, can you lend this scooter to my brother to have a look."
A few people just sat on the stone benches in the West Yard, and before they chatted for a while, Yan Shaoning couldn't hold back the monkey anxiously.
This Yan Shaoning seemed to be impatient. Li Zexuan was a little funny, so he said: "No problem, brother Shaoning wants to see it, don't hesitate to watch it."
Yan Shaoning heard the words and hurriedly lifted the scooter directly to the stone table, and then leaned in to observe carefully. I saw him turning the scooter up and down from time to time, and he kept sighing from his mouth. Within a quarter of an hour, Yan Shaoning had thoroughly studied all the structures of the scooter. He put down the scooter and looked towards Li Zexuan said:
"Xiaoxuan, although the structure of this scooter is simple, the idea is really surprising. Why didn't I think of such a simple and convenient thing before? Brother, I really can't figure it out."
Yan Shaoning hammered his head in annoyance.
Li Zexuan smiled and said, "Brother Shaoning, don’t be upset. In fact, if you think about it carefully, the structure of many things we use in our lives is generally not complicated. For example, the structure of a carriage is also very simple, but why are there hundreds of No one thought of making a carriage before?
, in the final analysis, is a problem of one's creative thinking. My master once told me that there is nothing impossible but not impossible. Because sometimes creativity is far more valuable than technology. If your thinking is not broad, you will never be able to create valuable new things. "
Yan Shaoning was like a divine initiation, and she smiled and said, "Yes, yes, that's what it means. Brother, I have encountered many similar problems before. It is obviously very simple, but I can't think of it, Xiaoxuan. It’s a good idea."
Li Chengqian nodded thoughtfully from the side.
Li Zexuan said modestly: "It's just that Shaoning brother is a fan of the authorities. Many times, if you jump out of the game and change your mind, you can often get unexpected results."
Yan Shaoning nodded in agreement, looked at the scooter, and said: "But Xiaoxuan, your scooter has a lot of imperfections. For example, the wheels will turn very jerky, and your front end The handle can only be used as an armrest, and cannot control the steering of the scooter."
Li Zexuan nodded, secretly saying that this buddy is worthy of a family of engineering, and he really understands the mechanical structure, and he can see the defects of this simple scooter at a glance.
"Well, what Brother Shaoning said is that when he made this scooter, it was just for coaxing the little girl's random actions. This scooter can indeed continue to be improved."
"Oh? So, Xiaoxuan, you already have an improvement plan?" Yan Shaoning was very curious when he heard that. He could see the problems with the scooter, but it didn't mean he had a solution to the problem now.
"My brother has some thoughts. Xiao Xi, you can go to the kitchen and bring me a stick that has not been burned." Li Zexuan told Xiao Xi.
He can barely write with a brush, but drawing pictures is really hard for him. The lines of engineering drawing need to be horizontal and vertical, and the soft tip of the brush is difficult to achieve, at least he can't.
Xiao Xi led the way. Li Zexuan saw that Yan Shaoning and Li Chengqian were both confused, and explained with a smile: "The younger brother is more used to drawing pictures with charcoal. I want to draw a drawing for brother Shaoning. It’s clear at a glance."
the two nodded.
After a while, Xiao Xi came over with a burnt stick. After Li Zexuan took it, he drew out his long sword and brushed a few swords. Everyone felt that there was a flower in front of them, and they saw that Li Zexuan had an extra slender wooden stick in his hand. The bottom was still pointed.
Li Zexuan is also the first time to "sharp a pencil" with a wind-chase sword. After seeing that the result is not bad, he can't help but sigh in his heart that he has become more proficient in the control of power.
"Good swordsmanship, I didn't expect Xiaoxuan to be good at swordsmanship." Yan Shaoning exclaimed.
Tang people are martial arts, and the children of high-ranking officials and nobles love the saber. Although Yan Shaoning is not good at swordsmanship, he still has eyesight. He did not expect that this new friend not only has unique ideas in equipment, but also looks quite good at swordsmanship. , Yan Shaoning is more and more interested in Li Zexuan now.
Li Zexuan didn't answer the conversation, he spread a piece of rice paper on the stone table and started drawing.
Past life, Li Zexuan is very proficient in mechanical drawing. Whether it is computer drawing or manual drawing, the drawings he draws basically do not need to be modified by the teacher, and can be sent directly to the factory for processing.
In his previous university, Li Zexuan’s college organized an internship at the FAW headquarters. Their task was to go to the workshop, draw down the key parts of the car that they had seen in the workshop, and calibrated the dimensions.
At that time, due to the very limited drawing conditions in the workshop, even the ruler could not be used. As a result, many students painted crookedly like a dog's planing, but Li Zexuan's paintings looked like works of art.
It’s not because he had attended art interest classes, but Li Zexuan’s ability to copy was very strong since he was a child. When he was young, he was able to completely paint the dragon on the wall against the New Year paintings on the wall, and the paintings were wonderful and pretty.
After going to university, Li Zexuan sometimes couldn't help but regret that he didn't go to the art academy. I have to say that Li Zexuan is an engineering dog with artistic cells.
At this moment, Li Zexuan closed his eyes in front of the rice paper, and recalled the structure of the ball bearing. What's amazing is that Li Zexuan quickly formed a three-dimensional structural model of the ball bearing in his mind. This strange scene scared him almost to exclaim.
opened his eyes and saw that several people were waiting for him to pick up the pen, Li Zexuan ignored the reason for the three-dimensional image in his mind, so he just picked up the pen and painted.
At this moment, it’s really eloquent. If there is a **** in writing, Li Zexuan feels very strange at this moment, as if his brain is a computer, and his hand is a printer, and the three-dimensional images in the brain are directly passed through his hands. Reappeared on rice paper~IndoMTL.com~ Soon, Li Zexuan drew the three views and isometric views of the ball bearing on rice paper. Of course, he did not mark the dimensions and tolerances. He is only explaining the principle of ball bearings. No need for these. Li Zexuan put down the pen and let out a sigh of relief.
Yan Shaoning can't wait to come up to see what Li Zexuan is painting.
I saw four different pictures painted on the rice paper. The lines are horizontal and vertical, with real and imaginary lines. This is the first time Yan Shaoning has seen this painting method, but why did he draw four pictures? Parts?
Yan Shaoning looked at Li Zexuan with a dazed expression.
Li Zexuan was inexplicably looked at by him, and wondered: "What's wrong, brother Shaoning? Is something wrong?"
Yan Shaoning pointed to the rice paper and asked embarrassedly: "Xiaoxuan, why do you draw four pictures? What does this mean?"
Li Zexuan was stunned, didn’t ancient craftsmen draw drawings like this? Don't they know the three views?
"Uh, brother Shaoning, it’s the first time for my younger brother to draw a mechanical drawing. Maybe the drawing method is different from yours. I don’t know how Shaoning brother did the drawing before?"
Yan Shaoning suddenly, "Oh, it turned out to be like this, just because there are some drawings on my brother, Xiaoxuan will show you."
After talking, he took out a roll of drawings from his cuff.
Li Zexuan took the drawing and opened it to see. Sure enough, the ancient craftsmen hadn’t started to use the three-view drawing method for their drawings. They only drew the floor plan, and marked the areas that could not be expressed in the floor plan. Li Zexuan couldn't help having a headache looking at the dense small print on the drawing. This is too inconvenient.
No, I have to popularize modern engineering drawing methods for Yan Shaoning, otherwise it will be too troublesome to communicate later, Li Zexuan secretly said.
