Chapter 374 Why are you worthy of it!

Li Weidong went to Tang Hao with a sample of the massage chair, hoping that Tang Hao could help improve it.

Walking into the laboratory, I saw Tang Hao was holding a Band-Aid and wrapping it around his index finger.

Tang Gong, what's wrong with your hand? Li Weidong asked.

Director Li is here. Tang Hao raised his head, smiled awkwardly, and then said, During the experiment, one of them was accidentally scratched by the blade of the soymilk maker.

Why are you so careless, you have to pay attention in the future, and then touch the blade after the power is off. Li Weidong said.

I only touched it after the power was cut off, but the blade was buried in the bean dregs. I couldn't see the position of the blade when I was outside, and I was accidentally slashed, Tang Hao said.

Let me see. Li Weidong said immediately.

It's just a small wound, there's nothing to see. Tang Hao said.

Li Weidong smiled helplessly: Who wants to see your wound, I want to see the soymilk maker!

Tang Hao also knew that he would be wrong, so he took Li Weidong to see the soymilk maker with an embarrassed look on his face.

This is just a sample, it looks very crude, it doesn't even have a casing, and even the motor is exposed.

The motor is under the soymilk maker, and above it is a removable container, and the blade is installed at the bottom of the container.

This design is not good! Li Weidong said immediately.

Director Li, is there any problem? Isn't the German juicer also designed like this? Tang Hao asked.

I have to change it, don't put the motor under it. Li Weidong said.

You mean, put the motor on it? Tang Hao began to frown and think.

Yes, it adopts the design of the upper motor. Li Weidong then asked: Give me a pen and paper, and I will draw it for you.

Tang Hao immediately handed over the pen and paper, and Li Weidong began to write and draw. Soon, Li Weidong drew the structure of the upper motor and handed it to Tang Hao.

Tang Hao looked at the picture, and suddenly showed an expression of sudden realization.

Why didn't I think of it! Director Li, your design is so wonderful! Tang Hao couldn't help exclaiming.

Tang Hao is not flattering Li Weidong, but the design of the upper motor is indeed very clever for a soymilk maker.

The original domestic soymilk maker, like the juicer, had a lower engine, and the knife surface was at the bottom of the container.

However, if it is used in a soymilk machine, this defect is obvious.

The early soymilk machine had insufficient wall-breaking ability. When making soymilk, a lot of bean dregs would remain, and the dregs would deposit on the bottom, covering the blade.

Since the position of the blade cannot be determined by sight, you must be careful when removing the blade or collecting the okara to avoid scratching your hands. And it's more troublesome to clean.

In order to solve the disadvantage that the bottom motor is easy to hurt the hand and is not easy to clean, Joyoung took the lead in introducing the design of the top motor, and with this design, it became the first brand of soymilk maker in one fell swoop.

This kind of successful design that has been proven, Li Weidong naturally wants to learn from it.

As an engineer in physics, Tang Hao understood the benefits of the top-mounted motor in an instant. He held the blueprint in his hand and couldn't wait to try the effect of the top-mounted motor.

Li Weidong stopped Tang Hao, and he said, Gong Tang,

You put the things in the soymilk maker for a while, and help me see something. I made a massage chair, but it always feels uncomfortable, you can help me take a look!

Only then did Tang Hao notice that there was a cushion with a back rest on a chair in the room, and it looked very thick. It should be the massage chair Li Weidong said.

I was dressing the wound just now, but I didn't notice that you brought something. Tang Hao said apologetically, then he walked up and checked the massage chair.

Soon, Tang Hao found the clue, and he asked, Director Li, aren't you using a roller here?

It's not a roller, it's a massage head, that's it. Li Weidong said, took a sample of the massage head from his bag and handed it to Tang Hao.

Tang Hao took the massage head and looked at it carefully, then frowned and began to think. After a while, he asked, Director Li, who designed such a massage head?

I designed it! Is it inappropriate? Li Weidong asked.

I can probably understand your design intention. You want to create a feeling of kneading through the overall rotation of the massage head, right? Tang Hao asked again.

As expected of Gong Gong, I can tell at a glance. Li Weidong gave a thumbs up.

Tang Hao went on to say, Your design idea is feasible, but I have a question, why don't you use a roller? For massage, the roller should be more comfortable, right?

Isn't this limited in size! This kind of backrest massage chair is relatively small, so it's better to use the massage head. Li Weidong said.

The 3D and 4D massage chairs of later generations use rollers, but that is a complex guide rail massage unit, which is already in the category of small robotic arms, which cannot be achieved with Li Weidong's current technology.

The massage chair made by Li Weidong can only provide fixed-point massage, and mechanical fingers are more reliable for fixed-point massage.

Tang Hao thought for a while, and then said, Director Li, let me help you improve the design of this massage head, and then adjust the angle of the massage head, which should increase some comfort.

Li Weidong then asked, Gong Tang, can you add some more ergonomic designs.

Well... Tang Hao suddenly showed an embarrassed expression, and then he explained: Director Li, although I know the subject of ergonomics, I have never studied it!

Even Tang Gong has never learned it! Li Weidong said with some disappointment.

Tang Hao continued; Ergonomics includes a subject of biomechanics. I have only seen some knowledge introductions in this regard, and I only understand a general idea, but if I ask it to do it, it really can't be done.

At this moment, a voice sounded from outside the door: What ergonomics? Isn't it just comfortable to sit!

Li Weidong looked back and saw that it was Tang Renjie who walked in.

Dad, why are you here! Tang Hao said immediately.

I heard that Director Li is here, so I came to have a look. Tang Renjie said.

Li Weidong said apologetically, Gong Tang, I'm sorry, I wanted to see you first, but I'm carrying a massage chair, and it's inconvenient to walk around, so I came here directly.

Massage chair? I'll take a look. Tang Renjie was very interested in the massage chair, and went up to try it himself.

Oh, no, it hurts my flesh, so I can't use it, I have to improve it. Tang Renjie stood up from the chair and continued, Are you talking about ergonomics?

Yeah, I think there should be some ergonomics on this massage chair, but I can't find anyone who understands this. Li Weidong said, looking at Tang Renjie expectantly: Tang Gong, you should understand ergonomics, right? ?

I'm a tube researcher, so I understand that stuff! Tang Renjie laughed and continued; But I know where to find someone who understands this.

That's great, I have to trouble Gong Gong to introduce me. Li Weidong said immediately.

Tang Renjie went on to explain: Actually, the person I'm talking about has not studied ergonomics seriously, but he can still improve this massage chair to make it more comfortable.

This person's name is Yan Junsen. He is about the same age as me, and he is retired. He used to be an engineer at the 175 Institute. You should have heard of this 175 Institute, right?

Li Weidong shook his head and said he had never heard of it.

Tang Renjie continued: The 175th institutes are military research institutes. I don't know exactly where they are and what they are studying, but I only know that there is such a unit in our Shanghai city.

Previously, our No. 5 Component Factory also undertook some military research and production tasks, so I got to know this Yan Junsen, who mainly studies the cockpit layout of tanks and armored vehicles.

There are three or four people in this tank, and operations such as observation, loading, shooting, and driving are also required. Therefore, the space layout must be reasonable, and the operator must be as comfortable as possible to avoid excessive Fatigue affects combat effectiveness.

If Yan Junsen is willing to take action, it will definitely be no problem to make your massage chair more comfortable.

Old Tang, is this Mr. Yan Junsen you mentioned easy to find? Li Weidong asked.

It's easy to find, anyway, this old Yan has already retired, and he usually has nothing to do. If you are free, we will find him this afternoon! Tang Renjie said.

...

That afternoon, Tang Renjie took Li Weidong to an old family home.

When I knocked on the door, I saw a bald old man in shorts and a vest opened the door.

Old Yan! Tang Renjie called out, and Li Weidong knew that this unremarkable bald old man was Yan Junsen.

Old Tang, why are you here? Is Tang Hao behind you? They all grow up to be big guys... No, your Tang Hao is much older than this guy! Yan Junsen said.

Old Yan, let me introduce to you, this is Director Li of Puppy Electric. Tang Renjie said.

Puppy Electric, I seem to have heard of it in an advertisement. Yan Junsen thought about it and asked, Is it the Puppy Electric that won the award abroad?

Yes, it's that puppy appliance. Tang Renjie nodded quickly.

The advertisement of Puppy Electric at the Cologne Electrical Appliances Fair was very effective. Although Yan Junsen had never bought Puppy Electric products, he had heard of Puppy Electric at that time.

Yan Junsen invited the two of them into the room. After the guests and the host were seated, Yan Junsen made tea for the two of them.

After a few greetings, Li Weidong explained his intention:

Mr. Yan, I recently developed a massage cushion, which is used to massage the back. I want to make this cushion more comfortable to use. I heard that you are an expert in this field, so I came to ask you for advice.

What kind of massage cushion? Yan Junsen asked.

Put it in the car downstairs, wait a moment, I'll go get it now. Li Weidong quickly went downstairs and brought up the massage cushion.

Yan Junsen studied it carefully, and then said: It's not difficult to change to be more comfortable, if I'm still in the unit, I'll be able to get it done for you soon.

But I am now retired, I need tools but no tools, and I need materials but no materials. Otherwise, let me draw a drawing for you, follow the drawing, go back and try it yourself?

Li Weidong could feel that Yan Junsen's words contained some resignation. But because of Tang Renjie's face, he was too embarrassed to refuse directly, so he made such an excuse, which was considered a help.

It doesn't take much trouble to draw a drawing with a pen. As for the effect of what is made according to the drawing, it is not within the scope of Yan Junsen.

This is not the result Li Weidong wants. He doesn't want Yan Junsen to work hard.

Li Weidong knew that it was time to activate the banknote capability.

I saw Li Weidong took out a stack of cash from his arms, put it in front of Yan Junsen, and said at the same time; Mr. Yan, I will pay for the tools and materials, here is 10,000 yuan, you can buy it first. tools and materials.

Seeing the ten thousand yuan, Yan Junsen's eyes suddenly lit up.

Although Yan Junsen has worked in the 175 Institute all his life, he is not rich. Although the salary in the military research institute is very good, even in the difficult times of life, he can guarantee the material supply, but he can't make any money.

Yan Junsen's retirement salary is only the level of ordinary civil servants. It is more than enough for food and clothing. It is impossible to make a fortune. At the very least, it is not easy to save 10,000 yuan.

However, Yan Junsen still declined: If you have tools and materials, you can't use so much money.

Mr. Yan, the remaining money is your hard work. Li Weidong replied with a smile.

Well... Yan Junsen hesitated a little. He had been in 175 all his life and accepted closed management. He really never took over private work. Now that he was asked to take over private work, he was really hesitant.

Tang Renjie, who was next to him, persuaded: Old Yan, you can take this money. Director Li is interested in your skills, and you are making money by your ability, and you have not been cheated, so what is there to worry about!

The temptation for a private life of 10,000 yuan is really big. With this money, at least the household appliances at home can be replaced with new ones. Especially the TV, be sure to change to a large color TV, so that when the grandson and granddaughter come back, they can watch cartoons happily.

Thinking of this, Yan Junsen nodded: Okay, Director Li, you can put this massage cushion here. I will study it carefully and formulate an improvement plan. At this time next week, come and pick it up!

Thank you, Teacher Yan, then. Li Weidong quickly thanked him.

...

In the blink of an eye, it was Father He's birthday.

Li Weidong drove to a nursing home in the suburbs of Beijing, and was stopped by the guards at the gate.

Obviously, Hutouben cannot be used as a passport here.

The guard saluted Li Weidong, and then asked politely, Comrade, who are you looking for?

I'm here to find He Lao. Li Weidong said.

Comrade, please show your ID card. The guard said.

Li Weidong handed the ID card to the guard. The guard took Li Weidong's ID card, went back to the guard room and made a phone call, then walked out and returned the ID card to Li Weidong.

Comrade, I have to check your trunk. The guard said.

Li Weidong opened the trunk again and checked it with the guards. There was only the massage chair in it.

After seeing that there was nothing suspicious, the guard said: He lives at No. 35, there are signs inside, you can follow the signs. In addition, you are not allowed to go faster than 30 miles, and you are not allowed to honk. Please You pay attention.

Thank you. Li Weidong thanked him and drove into the nursing home.

The sanatoriums are all small, single-family homes, which look very chic from the outside. Following the street signs, Li Weidong found No. 35.

He Anan was already waiting for Li Weidong at the door.

Come on, my uncle and aunt have already arrived. He Anan said.

Wait a minute, I'll take the birthday gift I gave to the old man. Li Weidong took out the massage chair from the trunk.

Is this the massage chair you're talking about? He Anan touched the massage chair curiously.

Li Weidong smiled and nodded: I specially made it for your grandfather, handmade, the only one in the world!

It's your intentions. He Anan smiled contentedly, and then dragged Li Weidong to the small courtyard of No. 35.

Following He An'an into the living room, I saw three men in their fifties sitting in the living room, and a few young people in their twenties and thirties.

He Anan pointed to one of the fat men and began to introduce: This is my dad.

Hello, uncle. Li Weidong greeted quickly.

He Anan pointed to the side again, a man wearing glasses who looked like He Anan's father 60-70%, said, This is my uncle!

Hello, uncle. Li Weidong then greeted him.

He Anan pointed to the third man, a man who was not tall, with thick eyebrows and big eyes, and said, This is my uncle.

Hello, uncle. Li Weidong greeted again.

At this time, a tall and thin woman in her early fifties came out of the inner room with an apron around her waist, as if she was cooking.

This is my mother. He Anan introduced.

Hello Auntie! Li Weidong greeted again.

Then He Anan introduced those young people to Li Weidong, except He Anan's brother He Xinhua, they were other cousins.

Mr. He did not appear, saying that he was resting, and he would probably come out after a while.

Everyone stared at Li Weidong and looked at him. Fortunately, Li Weidong was thick-skinned, but he had a calm expression.

In the end, the uncle asked, Xiao Li, I heard that you are not from the capital?

I'm from Qinghe. Li Weidong replied.

Qinghe, that's a poor place! The uncle frowned slightly, then asked, How many people are in your family?

I have four older sisters and one younger brother. All four older sisters are married. My parents are retired. Li Weidong replied.

Oh, there are quite a few family members. The uncle nodded and asked, Where do you work?

I set up a factory in our local Qinghe, doing a little business, Li Weidong replied.

Hearing this answer, the uncle snorted coldly, his face full of disdain: Isn't that a self-employed person!

Li Weidong can feel that the uncle's subtext is, you are a self-employed person, how can you be worthy of our family!
