When will I have a long tassel?

The so-called reverse design is to imitate or improve existing products. Even if there is innovation, it is just a repair on the original basis and cannot be separated from the original framework.

Forward design means that the designer starts from an idea and does not refer to existing products, but carries out a completely independent design and develops a brand 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.

As a newly industrialized country, China introduced Soviet technology in the 1950s, and its technological development for a long period of time was based on reverse engineering of Soviet products. By the 1980s, China began to introduce Western technology, and then entered the stage of reverse imitation of Western equipment.

As a means to catch 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. Even in developed countries, many technologies are reverse development of technologies from other countries and innovate based on imitation.

Among them, Japan is a country that excels in reverse development. Whatever new technology appears in the world, Japanese companies can copy it within a month, upgrade it in two months, make it beautiful, and then squeeze the original creator of the technology out of the market.

After decades of technological catch-up, China has gradually risen to the forefront of the world in many fields. As the forefront, the new problem we face is that there is no longer anyone to imitate and catch up with. Scholars like Xiao Wenjun, who are already at the forefront of international technology, were the first to feel this trouble.

"Forward design is very difficult." Xiao Wenjun said, "Everything we can think of has already been thought of by foreign countries. It is very difficult to find areas that foreign countries have not yet entered."

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

"I think so too." Xiao Wenjun did his part, but after speaking, he changed his expression like a bird and said: "But, this requires my husband's full support. Didn't you hear what others said? , Behind every successful woman, there is a hard-working man."

"What do you mean?" Tang Zifeng became wary. Whenever Xiao Wenjun showed such an attitude, he must have dug a hole for Tang Zifeng to jump into. Tang Zifeng jumped and jumped, and he learned a lesson.

Xiao Wenjun said: "I have thought about it. To find new ideas, it is useless to stay in the library or laboratory. You must go to the production line. I plan to find some factories to conduct on-the-spot research. I may have to go out and run a few Yue. I leave the issue of your child’s education to you, Mr. Tang.”

"Just leave the child to our parents." Tang Zifeng said nonchalantly, "Aren't your parents and mine both vying to take care of Yanqi? It's just the right time for you to be away from home, so let the elders on both sides take turns taking care of Yanqi. They are happy with it.”

"Of course it's okay to let the elderly take care of it. But Xiaoxiao said, you can't just let the old take care of your children, otherwise they will be spoiled. If I'm not at home, you have to come back often to correct some of the children's bad habits. You Still want to let it go?" Xiao Wenjun said.

"Is that Xiaoxiao of yours an engineer or a nanny? Why do I think her parenting theories are too rich?" Tang Zifeng complained with a smile.

The Xiaoxiao they are talking about is Dong Xiao, Xiao Wenjun’s roommate when he was a PhD student. That girl got married before she graduated with a Ph.D., gave birth to a child earlier than Xiao Wenjun, and taught Xiao Wenjun her parenting experience every now and then. However, Tang Zifeng said she was a nanny, which was a bit unfair to her. Dong Xiao went to Pujiang Automobile Group after graduation and is now a technical backbone in the unit. Tang Zifeng went to Pujiang Automobile Group to discuss cooperation some time ago and met with her.

"I'm telling you the truth." Xiao Wenjun slapped Tang Zifeng and said, "Didn't you just say that I don't want to make progress? You run around all day and rarely come back home. Why don't I spend more time with my children at home? What to do? Now I have to go out to do research, and I want you to come back and spend time with the kids. What’s wrong? "

"Professor Xiao, make no mistake, I am the general manager of Linhe Machine Tool Group, and my job is in Linhe. I am now in Beijing four months a year, and people in the group are already gossiping. If I ask for leave If you come back specifically to spend time with your children, I'm afraid Mr. Xie will have to come and 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 frequently. Otherwise, you take the child to Linhe and ask Zhang Jianyang to match you with a nanny. What do you think?"

"It's okay to bring the children to Linhe." Tang Zifeng said, "Aren't you going to the company to do research? We now have the largest machine tool industry cluster in the country in Linhe. Isn't that enough for you to do research? By the way, you said you want to When it comes to original design, I have a difficult project on hand right now. Without a foreign reference model, Chief Engineer Qin and the others can’t get it. Is Professor Xiao interested in taking a look?"

"Oh, what project is it?" Xiao Wenjun was indeed attracted. A project that Qin Zhongnian and others find difficult must be very challenging, which is exactly what Xiao Wenjun likes.

Tang Zifeng said with a smile: "This project has something to do with Xiaohui. To be precise, it is Suhua's project. Suhua and Fatty jointly opened a company to make drones. Later, due to insufficient funds, , Huang Liting also bought a share. Now they have launched four models, and the trial sales in the market have been very good, but the production cost is a bit higher, which has affected sales.

"Suhua came to me some time ago, hoping that Linji Group can help them design a batch of special machine tools for the manufacture of drones. According to his request, if these machine tools can be produced, their drone production cost can be A 50% drop would basically wipe out all European and American counterparts.

"However, the several special machine tools they want have no similar products abroad. In particular, the multi-station turning and milling machine tool proposed by Suhua requires high processing accuracy, low cost and high speed at the same time. , it is very difficult. A group of engineers from Canglong Research Institute have been busy for more than a month, but they have not come up with a satisfactory design.

"That's why Lao Qin told me about reverse design and forward design. According to him, for the batch of machine tools Suhua wants, we should adopt forward design ideas and don't have to look for reference materials abroad. .”

"Great, this is what I want to do." Xiao Wenjun said happily, "In school, we never imagined what kind of demands the practical department would put forward. These demands put forward by Su Hua are actually consumer electronics products Development brings new issues to the machine tool industry.

"There is no such demand abroad, so there are no machine tools that can meet this demand. In the process of solving these demands, we should be able to produce some new theories."

"What do you mean?" Tang Zifeng asked with a smile, "Are you going to pack up, pick up the baby and follow me to Linhe?"

"Bah! Even if I go to Linhe with you, I'm not going to help you take care of the baby. As we agreed, you have to be responsible for accompanying the baby."

A few days later, a group of strange tourists appeared at Linhe Machine Tool Industrial Park. They are said to be tourists because there are three people in this group, a boy and a girl, two young people, and a child less than two years old. They are clearly like a small family. Of course, such a combination would not be here to purchase machine tools or spare parts, because who would bring such a young child to discuss business?

But to say that they are tourists is strange. The Machine Tool Industrial Park is really not a tourist spot. It has no scenic spots or historical sites and is full of cold steel. How can it have any tourist value?

This family of three is naturally Tang Zifeng, Xiao Wenjun and their son Tang Yanqi. It was not a joke that Tang Zifeng asked Xiao Wenjun to come to the river with his child in his arms. He knew that Xiao Wenjun had stayed in school for too long and was eager to go to the company for a walk. But if it was as she said, running away for several months without being with her children, Xiao Wenjun himself would probably not be able to bear it without Tang Zifeng saying anything.

It is a good idea for a family of three to live in Linhe for a while. As the general manager of Linji, Tang Zifeng owns a large house here, which is enough for Xiao Yanqi to roll around in it. It is much easier to hire a nanny in Linhe than in the capital. Linhui Company, a subsidiary of the group, has a housekeeping company. The general manager of the group needs to hire someone for his family. Can the housekeeping company not provide a nanny who is one in a million?

As soon as Xiao Wenjun settled down, Tang Zifeng excitedly invited her to visit the Machine Tool Industrial Park in Linhe. He also specifically said that he would bring Tang Yanqi with him, saying that he would receive machine tool education from a young age and be able to take over from his parents when he grows up.

Xiao Wenjun had been listening to Tang Zifeng talk about building a machine tool industrial park in Linhe, and was a little curious about this industrial park, so he actually took his child and went out with Tang Zifeng.

Linhe City Gaotan Machine Tool Industrial Park, jointly built by Linhe Municipal Government and Linji Group, covers an area of ​​nearly 15,000 acres, which is a full 10 square kilometers. It is said that in order to get 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 project to be successfully approved.

Then came the equally difficult investment process. When the Linhe Municipal Government applied for this project, it was clearly determined that only machine tool-related enterprises could be arranged in the industrial park. At best, some catering, accommodation, and entertainment industries that serve park personnel would be allowed. Machine tools are actually not a big industry. Linhe City also spent a lot of effort to attract enough machine tool companies to settle in the park. 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. As soon as she entered the park, her eyes couldn't get enough of it. For a mechanical professor, the scenery in this place was too fascinating.
