I Became a Genius Engineer

Chulwoo Lee (5)

When I heard the call to my team, I hesitantly climbed onto the podium.

“Hello, this is Larva Fly’s Lee Cheol-woo. Let’s start the presentation right away. We created an app and device called House Notification to build an automated farming system this time, and in the future … (omission) …. Thank you for listening to our presentation. do.”

I think I was a bit nervous, but I thought it would have been a good enough presentation.

“We’ll have a Q&A session right away.”

“Yes, Mr. Cheol-woo, I heard you well. First of all, I want to ask you something. Who developed the app and device called House Notification?”

A middle-aged male judge sitting in the middle asked a question first.

“I developed them all.”

“Are you saying that Mr. Cheol-woo himself developed both the app and the device? One is for computer programming and the other is for electronic design?”

“Yes, it is.”

“Um, I see.”

The judges said with questionable eyes. I guess I can’t believe it.

“I will ask you a question.”

This time, the judge sitting on the right said.

“Yes. Please tell me.”

“Looking at the business plan, it says that the reason for developing House Alim was for my father. Please explain this part for a moment.”

“Oh, yes. My father returned to farming and started farming in a plastic greenhouse. And soon after, there was an accident in which the boiler did not work. At that time, I thought that such damage should not happen again. I did. My father was having a hard time at that time.”

In fact, I don’t know if my father had a hard time or not.

Because it was when I was in the army.

“Ohhh, to come up with such an idea for your father and put it into practice is such a great son. I bet your father will like it.”

“hahahaha, yes. They really liked it. It was rewarding.”

The judge sitting on the right was kind to me.

“It’s really amazing. An item that made use of filial piety. Are you making an automated facility for your father again?”

“Yes. That’s right. After my father returned to farming, there was no time to take a day off. That’s why it’s hard to have dinner together, let alone go on a family trip. I thought of easing that trouble.”

Minseok said, Hyo-sim! That’s the only operation we’ll be selected for the task.

And because I was busy with work, it was difficult to actually take a day off.

“Ohhh, that’s great.”

The judge shut his mouth, as if he had nothing more to say.

“Um…… You said Donghae University, where is it?”

This time, the judge on the left of the center said. Just by looking at it, it looks strict.

“It’s a university in Busan.”

“Well, luckily I passed the document screening.”

“yes?”

What kind of nonsense are you talking about, no matter how much the university I attend is called hakobang, you openly ignore it in an official setting like this?

“No, that’s right. An unknown university, what do you believe we support for commercialization?”

“… Just because you have a name, do you do everything well?”

“It’s not like that, but it’s highly probable. Well, making the House Keeper is commendable, but isn’t it too much of a stretch to do it in the future? Building an automated greenhouse, do you know how much machinery is required to go into it?”

Aren’t you ignoring me too much?

Of course you know that much.

“Yes, I know. First, to control the amount of sunlight, you need to control the giant on top of the house. Look at the screen above.”

This kind of question was predicted by Minseok, and he made a separate material behind the PPT.

“This is an automation we’re going to build. Look at this part in particular here.”

In that document, a special gear was designed.

“This gear automatically controls the axis and has the ability to shut off many variables. In addition, the gear ratio can be changed, so it can be used on any farm.”

It was a gear I designed myself. It was a bit geometrically shaped, but it had to be made that way to deliver enough power and eliminate complex environmental variables.

It’s a big deal if dirt gets in while the gears are turning.

And that’s not all.

It was possible to apply force in the other direction if an electronic signal was sent instead of transmitting force in one direction only.

That is, the force has multiple directions.

The reason for designing this gear was simple, as the judge said, there will be many mechanical devices in the house.

Designing them all is costly. So, a gear that can adjust the force in a free direction was needed.

Durability had to be sufficient, so it was made.

Free vector gear.

so named

“hmm……?”

The judges who were watching it started to take a closer look at the gear I made.

“What is it? That gear? Do you understand Commissioner Choi?”

“Linear motion and intersecting motion…. In addition…. You can even adjust the direction of rotation?”

The judge in the middle looked at it for a while and said.

“Yes. That’s right. I called this gear the Free Vector Gear. Currently, the patent registration is in progress.”

“Is it a free vector or a free directional gear?”

“Yes, it is.”

“No, Commissioner Choi, is that feasible? If there was a gear like that, why wasn’t it known?”

The person named Choi who sits in the center must have worked for a long time in the machine side.

“Heh heh… There was a gear that was designed once before, minus the linear motion.”

“You did?”

“I did, but it was ruined beautifully.”

“Why?”

“There were many reasons. Among them, the biggest problem was that I couldn’t handle the energy generated when changing gears.

“yes.”

Turned the PPT over to the previous page.

“Hey, if you look at it, there’s a gear change part, right?”

“yes.”

“It seems like I should actually make it, but…”

“Doesn’t it sound like you should actually try making it?”

“Yes. I can’t give you a definite answer. I haven’t tried it yet… so if it does, the applications will be endless.”

“What do you mean?”

“Yes. This… the automation equipment is not the problem, but the success of that gear seems to be more important.”

“As a professional, what is your personal opinion? Do you think it will come true?”

“To be honest, I think it will come true. How…”

“yes?”

“Cheol-woo.”

“yes.”

“Were you able to design such a geometric gear?”

how did you design it?

“Did you just do it?”

No big deal. I just thought I would need it, so I made it.

“……? Is that possible?”

“yes?”

“I just said it’s done… Oh, no. And, by any chance, is there anything else going on at Lavafly besides the house notification?”

I’ve been waiting for this question too.

“We are in the process of developing a multi-platform development tool called CAK with Blue Light, and are supplying the security program TSS to the military. This is how it is currently going.”

It also turned to the next page and informed the current status.

“CAK is committed to globalization, and TSS is already in use by the military. However, it was developed while in the military, so it will take more time to sign a formal contract yet.”

I heard from Minseok that CAK was going overseas because there was too little demand in Korea, and TSS seemed to be still in progress in many ways.

Since it was a project for the state, the progress was very slow.

“……? Is that really true?”

“yes.”

“Wow… that’s amazing.”

“I think your technical skills are sufficient.”

“It has a story. I like it. This item.”

The judges each said one word.

And the question and answer period was over.

“Due to time constraints, we will conclude the Q&A session. Thank you for listening to the presentation.”

came down from the podium.

After the presentation of the Science and Engineering Entrepreneurship Challenge, the judges gathered for a meeting.

“I have to drop this team. It’s too unrealistic. What does Chairman Choi think?”

“I agree.”

“The next team is… a Korean university team. They are well prepared for commercialization, and the items seem to be good. How is it?”

“I agree.”

The meeting went smoothly.

“The next team is the Lava Fly team. Huh…… This team passed, right?”

“First of all, passing is passing, but there are many things to say.”

“That’s right. What the hell is this team doing? It’s a house notification, but it is. Wouldn’t it be too absurd to build an automated greenhouse?”

I saw the team’s potential in Cheol-woo’s presentation, but I wondered if it would be difficult to realize an automated greenhouse yet.

“It certainly is. It’s not a typical factory, and the equipment that goes into automation is too vast and there are too many variables.”

“Yes. That’s right. But… there is a possibility. If you introduce that gear.”

“What the hell is that gear? I’m not quite sure yet.”

“It’s long to explain, but let’s take a look.”

Chairman Choi recalled the free vector gear that Cheol-woo had designed.

‘that… … . Gears, that’s awesome. How did you design it like that?’

Gears are generally responsible for only one movement. That was common sense.

So many gears and bearings are included in complex machinery. However, if the free vector gear made by Cheolwoo is used, the design drawing of the complicated mechanical device will be changed to a very simple one.

For example, a car has many gears.

First the steering system. Many gears are used to transmit the rotational energy of the handle to the wheel.

In addition, many gears are entered to convert the linear motion of the engine into the rotational motion of the wheels.

There are tens of thousands of those parts.

‘If I apply that gear to a car, how much parts can I save?’

However, if the free vector gear made by Cheolwoo is used, the number of parts will be drastically reduced.

Parts such as steering shaft, knuckle arm, steering gear, and steering wheel are not included.

‘The cost will be greatly reduced.’

Reducing parts is the same as saying cost reduction.

‘Of course, I don’t know if it can be applied to places like cars. It’s worth studying.’

Cheolwoo’s gear was still in the research stage.

If it is applied to a high-output car, there are still many things to verify, such as durability and speed.

‘Even if it’s not a car, I can make enough simple equipment?’

It is safe to call a car the crystallization of modern machinery, as it must be so sophisticated and have good output.

However, what Cheol-woo wanted to do now was an automated greenhouse.

Chairman Choi thought that it would be applicable enough.

‘If it’s really made right… … . Will a realistically applicable automated greenhouse be created at an affordable price?’

Automated greenhouses were not completely absent.

The equipment was too expensive, and there were still many variables, so it was only being operated on a small scale at the research institute for research purposes.

In other words, automated greenhouses are a technology under study.

‘It will be possible to supply existing farmhouses.’

However, Cheolwoo’s automated equipment was able to be made very efficiently with Free Vector Gear and House Reminder.

‘Is the agricultural revolution about to come again? … .’

Chairman Choi had high expectations for Cheol-woo.
