Tech house system

Before the start of school time, Wei Shuxun originally planned to stay at Zhou Quan's house, but after walking around the school, he found that the dormitory had opened earlier, so Wei Shuxun went back to the dormitory directly.

The other three roommates hadn't come yet. After cleaning the dormitory, they got on the Internet and lay down on the bed in a daze.Seeing the design drawing on the head of the bed, he remembered that the little rocket he made for Han Zhixin hadn't been finished yet. Wei Shuxun jumped out of bed and regained his energy in an instant.

Although it is called a rocket, it is actually an ordinary electronic toy. A catapult and a balance screw are installed at the bottom to ensure that the rocket can "fly" into the sky and fall vertically smoothly. It is not difficult to make.

Wei Shuxun spent more than three days burying his head to install all the internal electronic circuits, and the rest was only a launch pad and the appearance of the rocket.

The technology of the launch pad is still the electronic catapult, which is not difficult. What is a bit troublesome is where to get the shape of the launch pad and the shell of the rocket.

Wei Shuxun didn’t think so much at the beginning, thinking that there must be rocket toys in the toy market, but after looking around, they only found short, fat, cute plastic rockets, and more decent rocket models, but they were too small. , and it is not hollow, so there is no way to install electronic circuits.

After running around the toy market all day, he couldn't find a satisfactory rocket shape. Wei Shuxun was considering whether to order a model from the Internet and came back. On the way, he ran into Feng Wei, whom he hadn't seen for a long time.

The three who founded the laboratory together, Sun Yi and Liu Yongdong went abroad to study, only Feng Wei stayed at the school for graduate study, but Wei Shuxun and Wei Shuxun were not in the same school district, so they did not expect to meet at the school gate.

Knowing that Wei Shuxun was looking for the shell of the rocket model, Feng Wei thought for a while and said, "I know a friend who makes models, and I can ask him to make them for you, but do you have any blueprints?"

Wei Shuxun was overjoyed: "Of course!"

Even if it is a toy, Wei Shuxun has carefully designed it. The three major mechanics, mechanical design and other courses he just learned last semester just became his reference. Coupled with the simulation calculation assistance of the learning machine, he has already determined the shape of the toy. Diameter size, angle.Originally, I planned to disassemble and refit the toy after buying it. Of course, it would be more convenient to customize it in person.

So, the next day Wei Shuxun followed Feng Wei to find his friend's studio.The man's name is Lu Fei, he is a slightly fat young man, he is the only one in the so-called studio, and currently he is mainly responsible for the design of customized models and children's toys.

Wei Shuxun doesn't care about these things, he just needs the other party to make what he wants.Because there were detailed design drawings, Wei Shuxun didn't ask for any good materials, and Lu Fei asked for a very cheap price, so he made the rocket shell and launch pad that afternoon.

An electronic catapult was also installed on the launch pad. After Wei Shuxun got it, he asked Feng Wei to help him install the rocket, and he processed the launch pad on the spot.For Feng Wei and Wei Shuxun, these are very common tasks. They directly open their backpacks and take out tools for installation—the two are very similar in this respect, and there are always commonly used tools in the back.

When they were installing it, Lu Fei curiously came to the side to watch.Because Feng Wei is not familiar with the design drawings, he occasionally stops to look at the drawings during installation. Wei Shuxun doesn't blink at all, holding a small tweezers in his hand, clamping the small electronics on the table, just brushing Put it on, without a single pause.Lu Fei looked at his flowing movements with surprise.

Wei Shuxun installed the launch pad, tightened the last screw, and when he was packing up the tools, he found Lu Fei lying on the table next to him, staring at him blankly.

"What's the matter, Brother Lu?"

"Ah, are you ready?" Lu Fei had some reluctance in his eyes. It was the first time he saw such a wonderful work scene, like a coherent painting. He was stunned for a while, and even wanted to continue watching.

"Well, it's all right." Wei Shuxun nodded and turned to Feng Wei: "Feng Wei, how are you doing?"

"Okay." Feng Wei nodded, with an inexplicable expression: "This circuit is really complicated, and I was worried that it would be damaged during installation. How did you think of such a complicated circuit, Shu Xun?"

Back then, they taught Wei Shuxun's electronics, but in a blink of an eye, he has grown to the point where he even admires him.

"It's okay, I modified it according to the principle of the aircraft." Wei Shuxun didn't feel any difficulty when designing, and almost finished drawing the design drawing. Of course, he didn't think he was very good. After getting the rocket, he directly Head downstairs to the studio for an experimental launch.

When the launch is successful, the rocket is placed on the launch pad, and after being ejected about 15 meters into the air, it falls vertically smoothly.When Wei Shuxun originally designed the shell, he strictly used mechanical calculations to calculate the balance point, so that no matter what angle the rocket took off, it could maintain a 180-degree right angle when it fell. The electronic balance spiral was installed inside to slow down the falling speed. , and he also installed a colored light at the bottom, and the rocket flickered when it fell, as if it was being controlled by something and slowly descended.

Lu Fei, a layman, didn't say anything, even Feng Wei was dumbfounded.

"Shu Xun, what is the principle?" Feng Wei asked.

"Aircraft!" Wei Shuxun replied: "The four-dimensional aircraft I made before didn't have four-wave mixing... No..." Wei Shuxun put his finger on his chin and meditated: "Four-wave mixing doesn't seem to be a four-dimensional aircraft... …Seems to be……"

The one in the flight control center... on the real... rocket?

"No, no." He studied the aeroelastic pair domain with Professor Guan Cheng, and he didn't have any technology about aircraft.

"Feng Wei, is there a four-wave mixing inverse parabolic equation technology in the four-dimensional aircraft?"

"what is that?"

"..." Wei Shuxun turned his head and thought for a while, showing a confused look: "Then where did I learn it, learning machine?"

"..." Learning Machine: "I don't know either."

Wei Shuxun has learned too much and is too complicated, majoring in electronic science and technology, engineering mechanics, optics, as well as the future technology obtained from the learning machine, as well as the knowledge learned from the professors and researchers during the experiment.He absorbs everything he is interested in like a sponge, and then unknowingly transforms it into his own knowledge. Now even if he is a learning machine, he doesn't know how much Wei Shuxun has learned and to what extent.

"Oh...forget it." I really can't remember it, so Wei Shuxun forgets it, only to realize that Lu Fei and Feng Wei have played with his rocket several times.

"Be careful, don't dirty the shell, I'm going to give it away."

That being said, the nearby children were attracted by the toys, and they were standing by and watching. Wei Shuxun had no choice but to lend them to play for more than ten minutes before putting away the rocket under the reluctant eyes of the children.

"It's really interesting." Feng Wei couldn't put it down, and said to Wei Shuxun, "Shuxun, lend me your design, and I'll make one another day."

"Okay, take it."

"That..." Lu Fei interrupted: "Let me ask, is this rocket designed by Wei Shuxun yourself?"

"Yes." Wei Shuxun nodded.

Lu Fei's eyes lit up: "The design, technology, appearance, all belong to you?"

"of course."

Lu Fei's eyes became brighter: "Then Shuxun, do you plan to sell this technology?"

"sell?"

"Yes, I know a lot of toy companies. I think the rocket you designed must be very popular with children. How about it? Do you want to sell the technology?"

"...!!" Just as he was thinking about how to make money, someone suddenly delivered a toy to Han Zhixin. If he could sell it for a sum of money, it would be the same as picking up money for Wei Shuxun. Immediately wanted to nod.

"Wait." Feng Wei waved his hand: "Shu Xun, if you want to sell it, you might as well apply for a patent before selling it."

"That's right." Lu Fei nodded: "With the patent in hand, we can negotiate a better price."

"Oh..." Wei Shuxun always listened to the opinions of professionals on things he didn't understand: "How do I apply for a patent?"

Feng Wei and Lu Fei were really thinking about Wei Shuxun. Applying for a patent is not only conducive to negotiation, but they can also participate in the patent auction if they fail to agree, and they will not suffer any disadvantages.

But Wei Shuxun checked the requirements of the patent application and found it super troublesome.For the application fee, printing fee, maintenance fee, review fee, re-examination fee and other items, we first need to prepare about 4500 yuan, which can eat up the living expenses of this poor student for more than two months.These are okay to say, the most troublesome thing is the review.After submitting complex application materials, it has to go through complicated stages such as preliminary examination, publication, and substantive examination.When the reviewers have doubts, they have to make revisions or statements within the specified time.Just thinking about Wei Shuxun shook his head, he was so busy, how could he have time to "state" to the inspectors.

If so, at the fastest speed, it will take at least 5 months to get the patent authorization letter.Lu Fei said that in order to ensure that the technology will not be leaked, this toy rocket can only be given away after obtaining a professional authorization letter.

"What's the point of that..."

Wei Shuxun shook his head, the toy he gave to his friend had to be impounded for nearly half a year before giving it away, because it was related to the patent, Feng Wei didn't even dare to look at the design drawing, so he folded it and sent it back.

Although it is very happy to be able to sell for money, doing so is completely putting the cart before the horse.

"No need, I don't apply for a patent." Wei Shuxun said: "This technology is sold directly if the price is right. There is no need to apply for any patents. It doesn't matter if no one wants it. It's just for fun."

"Shu Xun?" Feng Wei was surprised.

"Really? Without patents, the price will be very low?" Lu Fei asked.

"Well, it doesn't matter." Wei Shuxun put the design drawing back into Feng Wei's hands: "Feng Wei, you can play with it, as long as it doesn't spread to outsiders."

Feng Wei was stunned for a moment, then laughed: "Thank you, Shu Xun!"

Lu Fei scratched his head: "Okay, the thing is yours, as long as you like it, but this rocket will be kept with me for the time being, and the price can only be negotiated if there is a real thing."

Wei Shuxun thought about it for a while, then nodded: "Yes, but it's only a week, I've delayed too long."

"No problem, one week is enough." Lu Fei opened the drawer, took out a few extra documents inside, and carefully locked the rocket in.

Wei Shuxun glanced at it, saw the text on it, and took it over curiously: "Modification of the automatic mahjong machine?"

"Oh, that!" Lu Fei explained embarrassingly: "A company I know that sells automatic mahjong machines said that they want to make some technical improvements and are looking for technology outsourcing. The price is very low, only [-] , Feng Wei refused to do it, haha, you must also look down on things like mahjong machines."

Feng Wei shrugged: "I don't look down on automatic mahjong machines, but I don't know much about mahjong machines, so I can't get started."

In Lu Fei's eyes, Wei Shuxun, who wears black-rimmed glasses and is calm and capable, is a template for a high-achieving student. Such a good student will never look down on a low-end gambling machine like a mahjong machine.

Unexpectedly, Wei Shuxun, a high-achieving student who was dismissive of selling patents just now, nodded eagerly: "I want it, I want it, I'll take this job!"

The mahjong machine explained, he is too familiar with it!
