I Became a Genius Engineer

Engineer Cheolwoo Lee (9)

After skipping class, when I entered the club room, Hye-jeong was there.

“Brother, didn’t you go to class?”

“Oh, I’m out of town.”

“No…… But if you go, listen carefully. Why did you come out?”

“It’s something I know anyway, and I came up with a good idea.”

“Good idea?”

“Yeah. I just thought I had to remodel the Freevector Gear, but that wasn’t the case.”

“Yes? What do you mean?”

Hyejeong asked with a curious expression.

“It is not a modification or improvement, but a new free vector gear that can handle high power and high rotation.”

“…… Yes? Making a new one?”

“Yeah. Until now, I was too caught up in stereotypes. It’s easy to make a new one.”

“Uh… wouldn’t it be easier to remodel with common sense?”

Hyejeong tilted her head and said.

“Modification is not the answer. There is no way.”

“Well, I see. So what can I help you with?”

“You said you could do 3D modeling before?”

“yes.”

“Let me 3D model what I sketched.”

“hehehe, leave that to me. It’s my specialty.”

Hyejeong was versatile not only in simple editing and design, but also in terms of design, such as 3D modeling.

“I’ll sketch it for a moment.”

“yes.”

I sketched a new version of the free vector gear I had in mind on an A4 sheet of paper around me.

Basically, it was a T-shaped shape with a saw blade, and one more geometric saw blade connecting the two to a structure with one more T on the horizontal axis.

After finishing the sketch, I showed it to Hyejeong.

“uh…….”

“Why? Is there anything you don’t know?”

“It’s strange. So two T-shaped gears go in and one more gear connecting them goes in? Is it a TT gear?”

TT gear? nice name

“Yes. That’s right. Did you understand correctly?”

“Yes. That’s right. Can I just 3D model this?”

“Is that possible?”

“Yes! I think it’s possible. But could you show me this part from various angles? There’s no content for the back part.”

“Oh, hold on.”

Hyejeong turned on her computer and started modeling, and I continued to give her sketches from various angles of the new equipment.

“Here it is.”

“Oh, the rear looks like this. It’s really strange. You said this is a gear that can handle high power and high revs?”

“Yeah, that’s right. Instead, gears may engage at low power and low rotation.”

“Can be bitten? What does that mean?”

“It’s going round and round.”

“Eh? Isn’t that not okay?”

“It’s okay, even if I wander a little, in the end… Well, I need to do some calculations for a moment.”

“Yes. I will continue working.”

Using engineering knowledge, a new gear. I calculated the theoretical performance of the TT gear attached by Hyejeong.

‘Let’s see, when it’s made of steel. The strength of steel… … . RPM is

It will be a variable value.’

I was in the middle of doing calculations by jotting down here and there on a notepad.

“Oh? Oppa, what are all these formulas?”

“What are you doing when you’re not working?”

“Eh… Total exploitation.”

“Oh, I didn’t mean to say anything.”

“hehehe, I know. So what are these? These formulas?”

“Ah, I’m calculating. How much force can be transmitted and how much rotation can be sustained.”

“and…….”

Hyejeong made an admiring expression.

“why?”

“No, isn’t it simply overflowing with ideas? Oops… I know how to do engineering math calculations.”

“It’s simple. Power is affected by strength, and the number of revolutions is affected by strength and the length of the saw blade, so you can make a formula with that. Of course, it’s theoretical, so I didn’t include the surrounding environment as variables.”

“Aren’t you really good at math?”

“Um, math? Well? It’s just out of necessity.”

“Really, great.”

“hahahaha, anyway, let me do some calculations.”

“Yeah! I’m going to be modeling again. Oh, and I’ve been wondering. If you make this, you’re one step closer to that result, right?”

As a result? Are you talking about blowing it up at a presentation?

“Yeah, that’s right. But I’ve thought about it a little, and everything else is good, but I don’t think it’s okay to harm Hyeonseong.”

“That’s right. I thought of it well. You don’t have to push yourself too hard.”

“But, I won’t just go over it. I’m going to reveal it in a way that doesn’t damage Hyeonseong.”

“how?”

“I’ll have to think about that a little more.”

“…”

“Let’s do some work.”

“yes!”

I kept counting.

‘Hmm, so even over 1 million RPM per minute is enough to function normally?’

As a result of the calculation, the RPM per minute was 100. In terms of the vehicle, it could have been less than expected.

‘Even if it’s lower than 100, it’s about 1:2 performance.’

Low RPM didn’t mean it wasn’t fully functional. Although there was a performance decrease of about 50%, it was fully guaranteed to work.

It was a huge improvement compared to the existing pre-vector gears, which were completely worn out and failed if the RPM exceeded 1000.

‘Then, is it strength?’

I also calculated how much power it could deliver.

‘100% at 10 mana or more, it drops little by little below that.’

Even if it drops little by little, it was possible to achieve more than 80% performance even at 1 mana.

A 1,000cc compact car has roughly 50 mana. This was great.

In the case of the existing free vector gear, it was possible to transmit power of less than 10 mana with low power. If it is more than that, the saw blade will come out and break down, just like the number of revolutions.

Compared to that, you get a huge advantage in terms of manageable power.

‘If this is enough, it can fit into the vehicle’s steering system and power unit.’

It was the convenience function of the vehicle that team leader Seo placed the order. However, if it is a TT gear made this time, it will be able to enter the vehicle’s power transmission system and the steering system that controls the vehicle’s wheels.

in other words… … . It goes into the core functions of the vehicle.

After the strategy meeting of Hyunseong Motors, team leader Seo and vehicle designer Mi-seon Choi stayed and talked.

“Chief Seo?”

“Yes. Designer Choi.”

Designer Choi Mi-sun graduated from Art Center College (ACCD) in the US and came to Hyeonseong after designing for a foreign vehicle company.

His title is Vice President of Design at Hyunsung Motors.

It is no exaggeration to say that Hyunsung Group’s cars were designed by him.

“How about what you said last time?”

“Last time? Which one?”

“What was that? You talked so loud about the invention of universal gears and the ability to design vehicles that had never existed before.”

“Ah… is it a free vector gear?”

“Yeah. Sure, that must have been the name. You know the design of the X-380? I heard you could build one. If you had that gear.”

The X-380 is a hypothetical car model for Hyunsung, whose designer Choi has previously sketched ideas for future cars.

The power transmission system was simple, so the vehicle was small and the output was good.

The interior was equipped with the latest electronic devices, and featured automatic driving using artificial intelligence, electronic parking and brakes.

“…”

“Why? No words? Can’t you just say it confidently this time?”

Chief Seo had nothing to say.

“Look, I knew that. How many times have I been fooled? When the hell will modern technology catch up with my design?”

“No, that’s… it might not be a futuristic design…”

“What did you say? Are you unhappy with my design?”

Designer Choi cut off team leader Seo’s words.

“No, it can’t be. hahahahaha… It’s a futuristic vehicle designed by designer Choi. Of course, such a vehicle will come out in the future.”

“So. To prove you’re right, build it. If that vehicle actually sells well, I’m sure I’m right, and if it doesn’t sell, then you’re right.”

“hahahahaha, I really want to make one too.”

Team leader Seo didn’t really like the X-380 designed by designer Choi, but what can he do?

Designer Choi, who studied a lot in the design field and has a higher rank than himself, says that.

Of course, I wanted to make such a vehicle apart from the design.

If a vehicle came out with a design like the X-380, it was obvious that the technology would be recognized.

“So why not? Unit price issue? Or

A technical problem?”

“It’s a technical issue. The gear I was talking about last time was a little, no, not enough to go into the vehicle’s powertrain.”

“Hmm, I can’t help it. So how’s that going? IONIK-1.”

“A hybrid engine model?”

“Yes. Do you have a release plan?”

“… not caught yet.”

“No, that’s when the design was completed, but it’s still dragging on.”

“It is necessary to deliver the power of the power from the gasoline engine well…. That’s the problem with the inverter and the part that gets power….”

The problem of transferring power to power was still a headache.

If you fix A, B is the problem, and fixing B causes the problem to be in C. So again, if you fix C, D doesn’t work, and if you fix D, problems arise in B and C.

In fact, Hyunsung’s hybrid engine could have been wrong from the design, not a single problem.

It was Hyeonseong who knew those problems, so he couldn’t launch it, and he didn’t want to admit that his technology was inferior to that of other automakers.

Team leader Seo was also frustrated about that part.

“It’s okay. That’s right, the development team doesn’t do anything right.”

Designer Choi shook his head and said.

“…”

Chief Seo had nothing to say.

“No, Toyo Motors is going to introduce a launch model at the expo next year. What the hell are we doing?”

“I’m doing my best.”

“No, there’s no point in doing your best. Shouldn’t we follow the toes, even if not as much as the Toyo car?”

“Yes. That’s right.”

“Ugh, I’m going. Let me know if you have any good news.”

“Yes! I see. Take a look.”

Designer Choi left the conference room first, and team leader Seo returned to his lab.

“Why is Team Leader Seo’s expression so bad? Did you fall in love with designer Choi?”

Upon returning to the laboratory, Chief Researcher Jung, a member of his research team, spoke to me.

“No, man. It’s been a long time. It’s not like that.”

“Eh, it was perfect just by looking at it.”

“This guy? Would you like to take a look at it?

“You know Team Leader Seo. We have to make it at least 30Kw, but the stability and efficiency are still very low.

“So, I’m trying to figure out how to solve it.”

“I’m working hard. A little more budget, please. I have a few things to try out right now, and if they get taken care of, maybe they will.”

“Budget? Do you know how much budget we burned? We said we were going to make a hybrid engine, but we’ve already received billions of dollars. We don’t have a budget, we’ll test it with what we have.”

Chief Jung already had a headache.

If you have the budget, you can put in an order and test a new one, but if you don’t have the budget, you have to repair the old one yourself.

“…… It may not be within the deadline. Then.”

“Ha, I don’t know. My head hurts right now. Seriously, why are you doing this?”

Team leader Seo seemed to have a rat in his head.

The lower ones are asking for more budget, and the upper ones are saying that there is nothing to be done, and they are asking us to present the results.

There was no mind up and down.

What’s even more painful there.

‘Oh, why am I so incompetent? I must have followed the elite course and came to this place.’

It was his own incompetence.

‘If I had been a better person, I would have been able to solve all sorts of problems in my heart’

Team leader Seo blamed himself.

Tiri-ring- Tiri-ring-

In the meantime, the phone rang.

“Mistress! Who are you at this hour?”

Team leader Seo nervously looked at the sender, and the caller was Lee Cheol-woo.

‘Lee Cheol-woo? What’s going on?’

There were only a handful of phone calls from Cheol-woo.

‘no way.’

Seo received a call from Cheol-woo.

-hello. Chief Seo. This is Lee Cheol-woo. How have you been?

“Hello. Mr. Cheol-woo, has it been a week?”

-hahahaha, I have contacted you because I have good news.

“Good news?”

-yes. A new type of free vector gear that can handle high power and high rotation has been completed.

“yes????”

Team leader Seo was stunned inwardly.

‘Crazy what? Was it really made?’
