At the beginning, he took his seven younger siblings to join Yi Zhonghai.

Chapter 69 Scooters

"Imitation is normal; everything that comes out will be imitated."

Hu Jieming waved his hand, completely unconcerned about the issue.

Yi Zhongding was also somewhat helpless.

People in this era don't care about intellectual property rights or patented technology at all.

After all, they also imitate foreign products.

They also don't pay any patent fees.

But he couldn't say much more.

We can't exactly say we're going to register a technology patent.

I guess I can make a living off patents in the future.

"This looks a lot like robots from abroad."

Hu Jieming picked up a Sun Wukong doll and examined it for a while before speaking.

"Huh? What robot? It's just a wooden doll, but I've modified the joints so it can rotate and be assembled freely."

Yi Zhongding pretended not to know what he was talking about.

Then he picked up a Sun Wukong doll and showed it to him.

The hands, feet, and head can all be detached.

This also uses mortise and tenon joints.

Two trapezoidal buckles at the interface.

By clamping both sides, the component can be squeezed into the bayonet.

He has no spring.

This is the only way we can do it.

"The concept is ingenious, much like a puppet show."

Hu Jieming made a comment.

"Director Hu, look at this car, it's quite interesting."

Wang Dafa is holding a toy truck, but the interesting thing is obviously not the truck itself.

He simply slid the truck across the ground with his hand.

Then the truck will move on its own.

What he's holding is the "inertia toy" made by Yi Zhongding.

Kangyuan Toy Factory hasn't even made this yet.

He didn't know if it existed abroad.

I reckon there is.

"Zhongding, how did you do that?"

Hu Jieming's eyes lit up. He picked up the truck and tried it out himself, then asked impatiently.

"Well, my sister is a bit lazy and doesn't want to push her own stroller, so she asked me if I could make a stroller that she can walk on her own."

"At first, I disassembled a metal wind-up frog from your factory, but I couldn't make the metal spring myself, so I modified it using rubber bands and bamboo strips, which have elasticity."

"But the rubber bands and bamboo strips broke too quickly, so I thought about it and used a few gears to modify the starting parts."

"This way, without rubber bands, you only need to rub the tire backward a few times, and it will run forward on its own."

Yi Zhongding briefly explained the ins and outs.

"Technology? How is that technology implemented?"

Hu Jieming pressed for an answer.

"Well, it's hard to explain. Let me show you the sketch."

Yi Zhongding scratched his head and said.

He then found a stack of blueprints.

I found a diagram of the inertial car components.

The basic version of this thing has only four parts: three gears and one flywheel.

The advanced model has a few more gears and flywheel plates, and a different internal structure, resulting in greater gliding speed and distance.

"It's that simple?"

Wang Dafa asked, puzzled and surprised.

"That's right. After friction backward, rotational kinetic energy is stored, which generates a forward force called inertia."

Yi Zhongding pointed to the blueprints and said.

"Can I open it up and take a look?"

Wang Dafa, seeing the opportunity, asked expectantly.

"Um, Technician Wang, you don't need to disassemble it. We have spare parts, and we'll assemble one for you on the spot."

"You took my brother's toy. If he saw his toy being taken apart, I don't know how much he would cry."

Yi Zhongding said with a smile.

He then walked to his toolbox and took out several gears, flywheels, and axles.

We assembled it right in front of everyone.

A glint flashed in Yan Bugui's eyes. He adjusted his glasses and stared at him intently.

Yi Zhongding found his appearance somewhat amusing.

This isn't a technical skill.

Anyone who's interested can figure it out by taking the toy apart and looking inside.

The key is to have hands-on skills.

A short while later.

The core power components have been assembled.

Wang Dafa took the part and turned the flywheel several times with one hand before stopping.

Then we saw the gears being driven to spin rapidly.

"Exquisite, truly exquisite. The creativity of the Chinese people is indeed boundless. The old man is right, the wisdom of the people is limitless."

"No one could have imagined that the first domestically created inertia toy would be born in the hands of a junior high school graduate."

"The reason given was that my sister was too lazy to push the stroller. How can you argue with that?"

Hu Jieming clapped and praised, and exclaimed in admiration.

"You flatter me. This thing is very simple. I guess your factory just hasn't thought in this direction yet, otherwise it would have been built long ago."

Yi Zhongding said modestly.

"Well, that's not how it works. What's difficult for some is easy for others. Many things seem simple, but before you actually do them, many people rack their brains and still can't figure them out."

"Zhongding, just for this toy, our trip was worthwhile."

Hu Jieming shook his head and said.

"I understand, this imagination and creativity are extraordinary."

Wang Dafa then came to his senses and praised him highly.

"Haha, let's keep watching and see what other treasures we can dig up."

Upon seeing this, Hu Jieming laughed loudly and said...

"What's this?"

Wang Dafa pointed to a scooter and asked.

"This, I call it a scooter. You can glide quite a distance with just one foot, it's also based on the principle of inertia."

"There are three models. One of them doesn't have gears or a flywheel. You can go as far as you want with one stomp."

"One model uses the principle of inertia, allowing for continuous leverage."

"There's another one that drains a child's energy, and that's this one."

"This is a replica of the spring-loaded principle, but its power comes not from stepping on the ground with your feet, but from pressing the handlebars with your hands."

"This handlebar is divided into two parts. The upper part is connected to the belt, and the lower part is the gear and freewheel."

"Just like that, pressing the handlebars down is like applying friction to the flywheel, and lifting the handlebars is like releasing kinetic energy."

"But these wheels are made of wood, they can't support an adult, so you guys probably won't be able to play with them."

Yi Zhongding demonstrated with a smile, but he didn't step on it.

"Let me see."

Wang Dafa took the scooter, then pressed down hard on the handlebars and lifted the scooter up in an instant.

Underneath the skateboard, both the front and rear wheels were moving forward rapidly.

That's right.

This one is two-wheel drive.

Yi Zhongding specifically bought a leather belt to modify it.

"Interesting, very interesting! If you replaced the car with a steel one and the belts with rubber ones, even adults would love it."

"And this thing can also replace a bicycle, Director Hu, don't you think?"

Wang Dafa said excitedly.

"Now that you mention it, it's true. And compared to making bicycles, it consumes far less steel."
