Siheyuan: I earned foreign exchange in the heyday

Chapter 388: Teach the factory technicians a lesson

Seeing that the technicians below were listening very attentively, Chen Changan continued.

"Well, let's make some improvements based on the appearance of the GAZ car.

If I want to design an off-road vehicle, what features do I need?

The first point is that it must have a high chassis. If the chassis is too low, all kinds of things on the ground will hang on the chassis. "

Then Chen Changan drew a few more strokes, first drawing a new chassis, and then erasing the lines that originally represented the chassis with his hand.

“Here we don’t consider shock absorption, tires, horsepower and other issues. We only consider the appearance.

Most of the users of off-road vehicles are gay men.

So what do gay men like? Domineering, tough, and spacious. Do you agree with these? "

Everyone nodded.

Chen Changan then began to make changes to the drawing of the GAZ car that he had drawn earlier.

There is no doubt that the GAZ car is also a classic. There is not much that can be changed in appearance.

The only thing here is the engine hood, which does not quite conform to the aesthetic tastes of later generations.

The front face of the GAZ car was changed to the front face of the later Dongfeng Mengshi, which makes it look more domineering.

As soon as the front face was drawn, there was a burst of exclamations in the conference room.

It is hard to say which of the two designs is better or worse. Some people like the GAZ car, while others like the Dongfeng Mengshi.

Chen Changan just wanted to let these people know that when they don’t know how to design, modifying it according to the classics is also a viable option.

The modification of the front face is complete. Chen Changan said again.

“Some people may think that the front face I modified is ugly, but that’s OK, you can design whichever one you think looks good.

Again, no matter who among you, if your design is adopted, you will be rewarded.”

After the front face was changed, Chen Changan became interested.

"Let's talk about pickup trucks. The characteristic of pickup trucks is that they can carry people and goods."

Then Chen Changan started to make some corrections on the side view he had just drawn.

A side view of a pickup truck is complete.

"See? The design of the exterior mainly depends on your positioning of this car.

If you want to carry people and goods, is it feasible to have people in the front and goods in the back? Of course it is feasible.

But our design cannot be fanciful. Design is a very rigorous matter.

You can't just draw on the blackboard like I did and call it a day.

For wheelbase, load, length, width, and other dimensions, accurate calculations are required.

Not only that, even the amount of ingredients used must be taken into consideration.

After all, our country is poor. If it is for personal use, even if it is ugly, it is acceptable to save materials.”

In the conference room, everyone no longer had the gloomy look on their faces.

When they heard Chen Changan say that it didn't matter if they were a little ugly, they all smiled.

Seeing that these people had regained their confidence, Chen Changan threw away the chalk in his hand and prepared to leave.

Hou Mingjun immediately grabbed Chen Changan and said, "Director Chen, we all know that the scooter was originally made by you.

You are really good at design. While everyone is here today.

Please tell us more, even if we may not understand it now, it can at least broaden our horizons."

After hearing Hou Mingjun's words, the technical staff in the conference room immediately echoed him.

"Yes, Director Chen, it's only been a while. Don't leave in a hurry. We still want to listen to your lecture."

"Yes, Director Chen. It's still early for dinner, please tell us more."

Most people of this generation have low educational background and limited vision.

But I am extremely thirsty for knowledge. How can I let go of the opportunity to learn so easily?

Seeing that everyone wanted to learn more, I looked at the time and saw that there was still some time before dinner.

So he said, "Okay, then I'll tell you more. What do you want to hear?"

Hou Mingjun quickly said, "What is streamlined, and what is a beetle."

Chen Changan immediately looked at Hou Mingjun unhappily.

"You can't forget these two words?"

Hou Mingjun didn't reply, but just smiled foolishly at Chen Changan.

"Okay, this is also about the exterior design, I'll give you a brief introduction."

After organizing his words, Chen Changan spoke again.

“We all know that when you move through the air, there is resistance.

Some people may say that the air resistance is very small and can be almost ignored. "

Chen Changan has seen many technicians nodding in agreement.

Chen Changan continued, "Compared to the power of the engine, the resistance is indeed not great.

But no matter how small the resistance is, it is real.

When you design the shape to have a larger drag area and the speed increases, the drag also increases.”

Seeing that everyone seemed to be thinking about something, Chen Changan was afraid that they would not understand, so he said.

“Suppose a bullet and a brick are placed in water. Given the same force, which one will go further?

They are bullets, definitely. Because of their shape.”

Then Chen Changan drew a car front in a certain direction on the blackboard, and then drew another car front with streamlined colors.

“Which of these two types of front ends has less resistance?

Does the second streamlined shape have less resistance?

Then during the driving process, the cars have the same displacement and the same mass.

Is the one with the streamlined shape more fuel efficient? "

This time, even Hou Mingjun understood and nodded.

I said to myself, "So this is called streamlined design. It really looks better than a boxy car."

After understanding the streamline, Hou Mingjun was afraid that Chen Changan would run away again, so he asked hurriedly.

"What is a beetle then?"

"When we design, a lot of inspiration actually comes from animals."

Then Chen Changan drew a bug on the blackboard. He said, "See? A bug.

When you see it, do you associate it with cars?"

Seeing that everyone in the conference room shook their heads, Chen Changan stopped communicating with them.

Then he began to simply draw the shape of the beetle.

As the Beetle appeared, everyone in the conference room was stunned.

Is this also a car? It actually looks a bit like a bug.

At this time, everyone in the conference room was terrified by Chen Changan's design ability.

According to Chen Changan's understanding of the Beetle, there is no doubt that everything can be transformed into the appearance of a car.

Hou Mingjun was also shocked. He looked at Chen Changan first, then at the beetle shape on the blackboard.

Hou Mingjun understood that when it came to design, no one in this room combined could compare to Chen Changan.

Thinking about what Chen Changan said to him at the beginning, it seemed that it was not just about streamline and beetle.

He forgot what the rest were called.

It was obvious that these designs were not what Chen Changan valued. He definitely had some good designs hidden in his hand.
