The so-called reverse design is to imitate or improve according to the existing products, and even if there is innovation, it is only repaired on the basis of the original, and cannot be separated from the original framework.

Positive design refers to the designer starting from an idea, not referring to the existing product, but carrying out completely independent design and developing a completely new product. The advantage of forward design is that the designer knows the origin of every technical detail, and can easily modify or upgrade it in the future.

China, as a latecomer industrial country, introduced Soviet technology in the 50s of the last century, and for a long time after that, technological development was a reverse design of Soviet products. By the 80s, China began to introduce Western technology, and then entered the stage of reverse copying Western equipment.

As a means of catching up with the world's advanced level, it is understandable for developing countries to engage in reverse design in the process of industrial development. There are not many original technologies in the world, and even in developed countries, many technologies are reverse exploitation of other countries' technologies, and innovation is carried out on the basis of imitation.

Among them, Japan is a country that has done an outstanding job in reverse development. If a new technology emerges in the world, Japanese companies can imitate it within a month, upgrade it in two months, and then squeeze the original creator of the technology out of the market.

After decades of technological catch-up, China has gradually become one of the world's leading countries in many areas. As the forefront, the new problem is that there is no longer an object to imitate and catch up with, such as Xiao Wenjun, a scholar who has stood at the forefront of international technology, was the first to feel such trouble.

"Forward design is very difficult. Xiao Wenjun said, "The places we can think of, foreign countries have already thought of it." It is very difficult to find areas that foreign countries have not yet set foot in. ”

"How can something that is not difficult be worth doing for my wife?" Tang Zifeng said.

"That's what I thought, too. Xiao Wenjun took it as a good deed, but after speaking, he changed his expression like a bird, and said, "However, this also requires the full support of my husband." Haven't you heard that behind every successful woman, there is a hard-working man. ”

"What do you mean?" Tang Zifeng became vigilant. But where Xiao Wenjun shows this demeanor? Must have dug a pit waiting for Tang Zifeng to jump in? Tang Zifeng jumped and jumped, and he learned a long lesson.

Xiao Wenjun said: "I've thought about it? Looking for new ideas? It's useless to stay in the library or in the lab, you have to go to the production line. I'm going to find some factories to do field research? It's possible to go out for a few months. The child's education is left to you, Mr. Tang. ”

"Just leave the child to our parents. "Tang Zifeng said nonchalantly? " Aren't your parents and my parents fighting to take Yanqi? Let the old people on both sides take turns, they are happy. ”

"Of course, it's okay to let the old man take it. But Xiaoxiao said that the child can't just let the old man bring it, otherwise he will be spoiled. If I'm not home? Do you have to come back often? Correct some bad habits in your child or something. Do you still want to leave it alone?" Xiao Wenjun said.

"You Xiaoxiao, whether you are an engineer or a sister-in-law, how do I think her parenting theory is too rich. Tang Zifeng complained with a smile.

The Xiaoxiao they are talking about is Xiao Wenjun's roommate Dong Xiao when he was studying for a doctorate. That girl got married before she graduated with a doctorate, and gave birth to a child earlier than Xiao Wenjun? In three days, I have to teach Xiao Wenjun parenting experience. However, Tang Zifeng said that she was a sister-in-law? But she was wronged a little, Dong Xiao went to Pujiang Automobile Group after graduation? Now it is also the technical backbone of the unit. Tang Zifeng went to Pujiang Automobile Group some time ago to discuss cooperation and met with her.

"I'll be honest with you. Xiao Wenjun slapped Tang Zifeng? Said: "Didn't you just say that I don't want to make progress? It's rare to go home? What if I don't spend more time with my children at home? Now I'm going to go out to do research, and I'm going to replace you with my children, what's not okay?"

"Professor Xiao, don't make me mistake, I am the general manager of Linhe Machine Tool Group, and my job is in Linhe. I've been in the capital for four months of the year now, and there are already people gossiping in the group. If I take a leave of absence to come back to accompany the children, I'm afraid Mr. Xie will have to come to talk to me. Tang Zifeng said.

Xiao Wenjun said: "I didn't let you stay at home all day, I just asked you to come back more diligently." Otherwise, you will take the child to Linhe and let Zhang Jianyang match you with a nanny, what do you think?"

"It's okay to take the child to the river. Tang Zifeng said, "Aren't you going to the enterprise to do research? We now have the country's largest machine tool industry cluster in Linhe, isn't it enough for you to investigate? By the way, you said that you want to engage in original design, I now have a tricky project at hand, there is no foreign reference model, Chief Engineer Qin can't take it, Professor Xiao is not interested in going to see?"

"Oh, what kind of project?" Xiao Wenjun was really attracted, the project that could make Qin Zhongnian and them all feel tricky must be very challenging, which is exactly what Xiao Wenjun's taste is.

Tang Zifeng said with a smile: "This project, speaking of which, has something to do with Xiaohui, to be precise, this is a project of Sovietization." Su Hua and Fatzi partnered to open a company that made drones, and later because of insufficient funds, Huang Liting also joined a share. Now they have launched four models, and the effect of trial sales in the market is very good, but the production cost is a little higher, which affects the sales volume.

"Su Hua came to me a while ago, hoping that Linji Group could help them design a batch of special machine tools for the manufacture of drones. According to his requirements, if these machine tools can be produced, the production cost of their drones can be reduced by 50%, and basically all their European and American counterparts can be wiped out.

However, the several special machine tools they want are not similar products abroad. In particular, a multi-station turning and milling integrated machine tool proposed by Suhua requires high machining accuracy, low cost and fast speed at the same time, which is very difficult. A group of engineers from the Canglong Research Institute worked hard for more than a month and did not come up with a satisfactory design.

"It was because of this that Lao Qin told me about reverse design and forward design. According to him, we should adopt the idea of positive design for the batch of machine tools that Suhua wants, and do not have to look for references abroad. ”

"Great, that's what I want to do. Xiao Wenjun said happily, "In our school, we couldn't imagine what kind of needs the practice department would put forward. These requirements put forward by Suhua are actually new topics raised by the development of consumer electronics to the machine tool industry.

"There is no such demand abroad, so there is no machine tool that can meet this demand. In the process of addressing these needs, we should be able to generate some new theories. ”

"What do you say?" Tang Zifeng asked with a smile, "Are you packing up, hugging the baby and going to Linhe with me?"

"Phew, even if I go to Linhe with you, I won't help you take the baby, I said okay, you will be responsible for accompanying the baby. ”

A few days later, in the Linhe Machine Tool Industrial Park, a strange group of tourists appeared. They are said to be tourists because this team is a total of three people, a man and a woman, two young people, with a child less than two years old, it is clearly a small family pattern. Such a combination, of course, will not be to purchase machine tools or spare parts, because who would bring such a young child to negotiate business?

But to say that they are tourists cannot but make people feel strange. The machine tool industrial park is really not a tourist spot, there is no scenic spot and no monuments, there is cold steel everywhere, how can there be any tourist value?

This family of three is naturally Tang Zifeng, Xiao Wenjun and their son Tang Yanqi. Tang Zifeng asked Xiao Wenjun to come to the river with the child in his arms, but it was not a joke. He knew that Xiao Wenjun had been in school for too long and was anxious to go to the company. But if it is really as she said, go out for a few months in one go, not with the children, and don't need Tang Zifeng to say anything, Xiao Wenjun himself probably won't be able to stand it.

It is a good idea for a family of three to come to the river for a while. Tang Zifeng, as the general manager of Linji, has a very large house here, which is enough for Xiao Yanqi to roll around in it. It is far easier to hire a nanny in Linhe than in the capital, and there is a housekeeping company under the Linhui company under the group, and the general manager of the group has to hire people at home.

Xiao Wenjun just settled down, Tang Zifeng happily invited her to visit the machine tool industrial park in Linhe, and specially said that he wanted to bring Tang Yanqi, which was called to let him receive machine tool education since he was a child, and he could take over his parents' class when he grew up.

Xiao Wenjun has always heard Tang Zifeng talk about the construction of a machine tool industrial park in Linhe, and he is also a little curious about this industrial park, so he really took the child and went out with Tang Zifeng.

The Linhe Gaotan Machine Tool Industrial Park, jointly built by the Linhe Municipal Government and Linji Group, covers an area of nearly 15,000 acres, that is, 10 square kilometers. It is said that in order to take out this land, the Linhe Municipal Government went to the provincial and national planning, land, urban planning and other departments hundreds of times, and agreed to a series of harsh conditions, which allowed the industrial park to be successfully approved.

Then, there was an equally difficult process of attracting investment. When the Linhe Municipal Government declared this project, it was clearly determined that only machine tool-related enterprises could be arranged in the industrial park, and at best, some catering, accommodation and entertainment industries serving the personnel in the park were allowed. Machine tools are not a big industry, Linhe City wants to attract enough machine tool companies to settle in the park, it is also spent a lot of effort. There is no need to elaborate on the hardships involved.

Now, what Xiao Wenjun sees is the machine tool industrial park that has begun to take shape, and as soon as she walks into the park, her eyes are not enough. For a professor in the Department of Mechanics, the scenery of this place is simply too fascinating.
