Chapter 48 Design
After Wall-E explained it, Lu Xin understood.

It turns out that humans in the cyber world have also fought against cat hair for a long time.

At the beginning, some biologists invented anti-hair loss drugs. As long as they are used for cats, they will not shed hair, or they will rarely shed hair. The cost is that the life span of cats will be greatly reduced.

Finally, a shit-shoveling officer in mechanical engineering invented a real hair removal machine.

The principle is somewhat similar to the combination of a vacuum cleaner and an electric iron. There are thousands of specially designed suction holes in the machine, which will generate a strong airflow to suck out all the cat hair on the clothes without leaving any residue.

Then the specially designed hair guide tube on the wall of the machine will send the cat hair from the guide tube to a small hair storage box at the bottom for easy hair removal.

The most amazing thing is that this hair removal machine can also iron clothes.

In the process of cleaning cat hair, the folds on the clothes will also be ironed neatly.

It is really convenient and quick, and it is a must-have artifact for raising cats at home.

"Do you have any blueprints?"

"This is just the most common machine. It doesn't need a blueprint. You just need to find an old machine and disassemble it to study it, and you can imitate it."

Hearing Wall-E's words, Lu Xin became even more excited, and then he thought of a very important question, "By the way, how much does it cost to make a robot like this?"

Wally: "The cost of this hair removal machine is not high. What is expensive is its design principle. Its suction nozzle is different from ordinary vacuum cleaners. There are thousands of tiny suction holes in the mouth, which can quickly remove hair from clothes. dust.

But at the same time, it also designed a spoiler hole on the side, which can prevent the clothes from sticking tightly to the nozzle when absorbing hair, which will affect the effect of absorbing hair.

There is also a capillary tube, which is also carefully designed.

This hair remover has won the Top Ten Most Useful Inventions Award of Tianlan Federal Republic in 2051. "

When sucking hair, the nozzle can not suck clothes. This is really amazing. Lu Xin immediately said, "Go find a hair remover and show me."

"it is good……"

……

Four robots were dispatched together, and an hour later, a hair remover was successfully found in a certain building.

This hair remover is really about the size of a household hair dryer, but the shape is very delicate and perfect. Just looking at the shape, it is no problem to sell it for 1000 yuan.

The mouth is flat, about 10cm wide, and the size can be adjusted, which is very convenient.

After charging, he experimented, grabbed a little dust and sprinkled it on the bottom of his trousers, and turned on the switch.

"Hiss..."

The sound of the vacuum cleaner is very small, almost as loud as the sound of a razor. I have to admire that the noise reduction technology of Cyberworld is really awesome.

Then he attached the machine to the bottom of his trousers.

If you look carefully, you can find that the dense suction nozzles in the middle of the hair remover have strong suction, and the dust in the middle of the trousers and the trousers below will float up, but the side of the suction nozzle produces turbulence, so that the trousers are not adsorbed on the suction nozzle .

"Fuck, this design is really awesome!"

Lu Xin couldn't help but be amazed.

Then he experimented with the effect of ironing. This was the same as that in the main world. It needed to add a little water so that it could be ironed while vacuuming.

After experimenting for a while, he had to marvel again at the technological level of Cyberworld.

It is a pity that the advancement of science and technology has not brought many benefits to the poor, and those who should be poor are still poor.

However, Lu Xin soon discovered that the "cost is not high" in Wali's mouth is completely different from the low cost in his understanding.

Opening the shell of the hair remover, he suddenly found that there are densely packed control chips inside, the metal tube of the vacuum tube in the middle, and the hair guide tube on the side, and the power supply copper wire is made of very solid materials.

Lu Xin was speechless for a moment.

Such a machine would probably cost 2000 yuan in the main world.

Coupled with the profit from operations and self-retention, it is estimated that it will cost at least 4000 yuan to [-] yuan in the hands of consumers.

This kind of hair suction device is not cheap at all. Except for a small number of rich people, most shit shovelers are reluctant to buy it.

"No! Cost suppression must be carried out!"

Lu Xin immediately asked Wally to dismantle the machine.

He went back to the main world to do some comparison and calculation based on the list that Wall-E took out.

Sure enough, the cost is 2200 yuan.

After Lu Xin returned to the cyber world, he said to Wall-E: "Remove the lithium battery block and use wireless... Forget it, let's make two types, one wired and one wireless.

Remove the ironing parts, just leave the suction hair... Forget it, make three models, wired, wireless, plus this advanced version.

The most common chip will do. You can re-optimize the control system later. Anyway, it’s just hair removal. Such a good chip is really a waste.

In addition, the shell material, as well as the copper wires and copper pipes inside are replaced partly..."

After substantial cost reduction, the material cost of the basic version of the hair aspirator was controlled at 700 yuan, less than one-third.

Then counting labor and operating costs, Lu Xin estimates that the price of a hair remover will be around 2000 yuan, with a 50% gross profit.

Seeing the result calculated by Wall-E, Lu Xin was also a little tangled.

The price of this hair remover is still very expensive for most shit shovelers compared to more than a dozen 20 yuan hair sticking devices.

Just like regular hair dryers and Dyson hair dryers, although they like Dyson, most people will choose regular hair dryers in the end.

Without it, there is no money.

But the cost can no longer be suppressed, otherwise the life of the hair remover will be greatly reduced.

So it can only compress profits.

"Okay, let's do this first, you make the design as soon as possible."

"Good master..."

……

……

In the next few days, Lu Xin was very busy.

While busy with the opening of a gold and jewelry store, the other side is also busy with the development of hair removers.

A mere hair remover is a piece of cake for Wall-E, who has self-learning ability.

It only took Wally 10 minutes to make a design drawing of a beautiful and elegant hair absorber according to Lu Xin's request.

Later, according to the design drawings given by Wally, Lu Xin paid a high price to find someone to make a custom mold.

Five days later, all the customized accessories arrived, and Wally assembled the hair remover.

However, the hair remover is not good at this time, and the control algorithm program needs to be re-optimized to adapt to the cheap chip, otherwise the high-speed machine will easily burn the motherboard.

Fortunately, the strong artificial intelligence robot is not blowing. After giving the specific parameters, in just a few breaths, WALL-E completed the optimization of the control algorithm of the hair suction device.

In the past few days, Lu Xin specially collected dozens of cat fur clothes, cotton jackets, T-shirts, sweaters, cotton pants, etc., for experiments.

These clothes are particularly prone to sticking hair, and it is not easy to remove after sticking hair.

When Wally said that the optimization was completed, Lu Xin couldn't help being nervous.

After plugging in the power supply, power on smoothly.

Then, with nervousness, he picked up the hair aspirator, and after pressing the switch button, the high-speed suction port on the top of the aspirator began to vibrate, but the sound was very small, almost as loud as the sound of a razor.

I have to say that it was produced by Cyberspace, which is really not a bragging rights.

The noise control of this imitation is still more than ten blocks away from the earth.

Lu Xin then picked up a piece of clothing and attached the hair absorber to it.

The result is the same as the previous test results, where the hair aspirator passes, there is no hair left on it.

Lu Xin opened the bottom cover, and the cat fur inside was compressed into a small fur ball.

"Hahaha... awesome!"

Lu Xin was very excited.

Although it is the principle of a vacuum cleaner, those carefully designed thousands of suction holes can definitely make every trace of airflow exert its maximum effect, and it will not cause damage to the fiber structure of the clothes.

It is precisely because of this that such incredible results have been created.

Even the cat hair that got in the crevices of the clothes was sucked out.

Holding back his excitement, Lu Xin experimented on the remaining dozens of clothes one by one.

The result was without exception, the cat hair on the clothes was sucked clean.

……

……

By late July, the weather is getting hotter and hotter.

At noon, the egg was broken on the road, and it would not be long before it would be cooked.

Inside the gold and jewelry store, Dong Yan and Zhang Jiani were sitting behind the counter blowing on the air conditioner.As for Zhao Ying, today is a day off.

It has been a whole week since it opened, and less than 2000 grams of gold have been sold in total.

Among them, 1500 grams of gold was bought by Lu Xin, a friend of the boss.

All three were very anxious.

The business is not good, the rent, water, electricity, labor and wages are all indispensable. They are really worried that the boss Lu Xin will not be able to hold on, and will close the store at that time.

Dong Yan and Zhang Jiani had just arrived, so of course they didn't have any deep affection for Lu Xin, the boss.

It's purely because the salary and treatment given by the boss Lu Xin is better.

The basic salary is 5000, overtime and performance are calculated separately, and five social insurances and one housing fund are also paid, including food and housing.

Most importantly, this boss is very humane.

Like other gold store clerks, they have to stand at the door to attract customers in summer, but they don't need it, and they are allowed to sit down and rest when there is no one else.

Where can I find such a good boss?
"Dingling jingling——"

Just when Dong Yan and Zhang Jiani were in a daze, the bell hanging behind the door rang.

The two people were shocked immediately, stood up from the stool, and said with a smile: "Welcome to Tianlan Gold!"

The one who came in was a very young looking woman, dressed in casual clothes, with wide sunglasses on her face, so she couldn't see her face clearly.

After the woman came in, she looked around the store, then walked to the counter, pointed to two of the one-buy 3D hard gold and ancient gold bracelets and said, "Wrap these two up for me."

Dong Yan and Zhang Jiani were overjoyed when they heard this.

3D hard gold and ancient gold bracelets are both priced at a buyout price, which can reach 800 yuan per gram, which is much more expensive than gold that is calculated by gram. Of course, the profit of their gold shop is also very high, which can reach 50% .

And this is why many gold and jewelry stores, which seem to be deserted, rarely close down.

Because it’s really not open for three days, and it’s open for three days.

"Thank you, a total of 32868 yuan."

"OK……"

The woman said something, then directly took out her mobile phone, opened the payment code and asked Dong Yan to scan it.

And at this moment, Lu Xin's voice sounded at the door.

"Sister Dong, don't take money..."
