Fortunately, the food was delivered at this time, Xiao Wen's attention immediately turned to the dining table, and without even saying a polite word to Tang Zifeng, he began to put down the chopsticks, it seems that she said that she was hungry before, and it was not a lie.

The two of them ate tacitly, and did not hold each other's dishes to show their affection like the little couples at other tables, which can be regarded as a kind of style of children of the rivers and lakes.

After eating for a while, Xiao Wen's speed slowed down significantly, and he began to have time to continue chatting with Tang Zifeng. Tang Zifeng was not hungry originally, so he put down his chopsticks at this time and restarted the previous topic: "By the way, Wen, you said on the phone, it's a little troublesome now, what is it?"

"I was a little optimistic about the workload, and I thought I could design the machine alone," says Chauvin. Now it seems that I may not be able to complete this task alone, I wonder if you can ask the technical department of Linyi Machine to help. ”

"What is the main aspect of the workload?" Tang Zifeng asked.

"It's mostly the computing aspect," Chauvin said. My heart is a little bigger, and I want this machine to be able to machine steel with lower strength, so that the stiffness requirements for the various parts of the machine are increased. And this machine tool must be packed in a toolbox, which determines that the bed, arm and other components can not be too thick, to improve the stiffness, it is necessary to use special steel, and this will lead to a significant increase in cost.

"I now think about the need to comprehensively calculate the stress of the machine under the conditions of processing various different materials, to determine what kind of material can be used to ensure both the stiffness requirements and the maximum cost savings, and this calculation is very large, there are too many factors to consider, if I do it alone, I am afraid that it will not be completed in half a year. ”

Of course, the mini machine tool envisioned by Tang Zifeng will not be used for industrial purposes, it is just a toy for industrial enthusiasts. This kind of mini machine tool is not uncommon in later generations, and there are many industrial enthusiasts abroad who will buy such machine tools, put them in the garage, and occasionally use them to make a small trick to satisfy their own production habits.

Because the size of the machine tool is very small, and out of the need to "play cool", all the parts should be stuffed into a toolbox, so as Xiao Wen said, its bed, arm and other parts can not be made very thick, and it will be deformed in the case of large force. Therefore, this kind of machine tool is not suitable for processing steel, and can only be used to process wood or aluminum, which is also what Tang Zifeng told Xiao Wen in advance.

But Xiao Wen is a person who likes to challenge herself, she thinks, in addition to this kind of machine tool as a toy, can it also have some practical value? For example, if a small part at home is broken, the owner can use this machine tool to process a part and replace it, so that the value of the machine tool is much greater than the original.

Some of the parts used at home are made of steel, of course, they are generally not high-strength steel, and ordinary steel is enough to use. Chauvin's idea was to increase the structural stiffness of the mini machine to the point where it could process ordinary steel, which led to a significant increase in the amount of design work.

Tang Zifeng also has a bit of industrial common sense now, Xiao Wen briefly explained to him, and he understood what was going on. He thought for a moment and said, "That's a good idea. Depending on the material, the range of application of the machine is also different. I can divide the machine into several grades, which can only process wood, aluminum, and ordinary steel. The price of each grade is different, and the highest grade is sold to a local tyrant at a price of 10,000 US dollars, and there is no counteroffer. ”

"This is too exaggerated, isn't it?" Xiao Wen smiled, "I have probably calculated that the cost of a set of such machine tools will not exceed 2,000 yuan, which is less than 300 US dollars when converted into US dollars." Even if you use special steel to make the bed and arm, it will be at the top for $1,000, so why can you sell it for $10,000?"

Tang Zifeng said: "First of all, there must be something wrong with your algorithm. You say that the cost of machine tools is low, just because you are calculated according to the labor cost of China, if you change to the labor cost of foreign countries, just to make these small parts, how much labor does it take? In addition, what we sell is not only the manufacturing cost, but also an idea, just this idea, not worth 5,000 US dollars?"

"This is an idea that other people can do. Chauvin said.

Tang Zifeng said: "So we must hurry up and apply for a patent, how can this machine tool be regarded as a utility model? As long as we register a patent, people should consider imitation." In the domestic market, it doesn't matter how those copycat companies want to imitate, anyway, there will be no local tyrants in China who can afford such machine tools. ”

"The main thing is that the local tyrants don't need machine tools. Xiao Wen smiled and corrected for him.

"How did I hear a local tyrant say he wanted to buy a set just now?" Tang Zifeng looked confused, as if recalling which local tyrant said this.

Of course, Xiao Wen knew that he was making fun of himself, because she was the one who said that he wanted to have a set of this kind of machine tool just now, and she was indeed one of the local tyrants.

In the past year or so, Tang Zifeng and Xiao Wen have jointly developed many new products. Each new product was conceived by Tang Zifeng, Xiao Wen realized it, and then sold the patent to Linyi Machine for production. Although those small products were not as popular as the previous wood carving machine tools, they also created hundreds of thousands to millions of revenues for Linyi machine, accumulating a lot, and these products are still of great help to Linyi machine.

There is a tacit understanding between Linyi and Xiao Wen, and each new product will pay a certain percentage of the patent licensing fee to Xiao Wen. After coming and going, Xiao Wen became a rich woman with a net worth of millions. Of course, this matter is only known to a very small number of people, and Tang Zifeng is undoubtedly one of them.

Xiao Wen is not a person who pursues a luxurious life, but with money, the concept of consumption will naturally undergo some changes, such as buying himself a mobile phone, buying a few more expensive clothes, and then subsidizing his parents to buy a luxury house in Wulang City, which is needless to say.

Every time Tang Zifeng saw Xiao Wen, he always teased her as a new tyrant in Tsinghua University, Xiao Wen was still a little resistant to this statement at first, but after a long time, he accepted it and felt that he was indeed a tyrant.

Hearing Tang Zifeng talking about the local tyrant again, Xiao Wen just pretended not to hear it, and said: "The design of this machine tool still has some skills, especially to integrate the functions of machine tools, milling machines, drilling machines, etc., which is equivalent to many components that need to adapt to different processing methods. Registering the design of these multifunctional components as a utility model basically blocks the way for others to imitate them. If others want to bypass these designs, even if they can be realized, the cost will definitely be greatly increased.

"As for those small enterprises in China, it will be more difficult to imitate this kind of machine tool. Most of the components of this machine are relatively small and need to be precision machined, which I don't think those small companies have the ability to do this kind of precision machining. ”

Tang Zifeng said: "It doesn't matter, as long as they don't sell abroad, I don't care how to imitate it in China." If I want to sell abroad, I have to go abroad to find a lawyer to clean them up, and I think that foreign agents would not dare to risk the world's condemnation and represent their infringing products. ”

Xiao Wen nodded in agreement, and then returned to the original topic, and said: "Then, there is only one problem left now, you need to find someone to do the follow-up calculations, and I can provide the ideas, but the force relationship between so many components is very troublesome, and I can't do it alone." ”

"Why didn't you think of asking your classmates to help you do it? I look at your two roommates, aren't they...... Well, I mean, they look like they're stupid at the sight of reading. Tang Zifeng was witty again.

Xiao Wen glanced at Tang Zifeng, and then said: "My two roommates, one is named Liu Yidan and the other is called Dong Xiao, they are both girls with very lively personalities, I will introduce you another day." Actually, I also thought about asking the two of them to help, but I didn't think of a specific way, if I didn't do it well, it might affect the relationship between my classmates. ”

"Affect the relationship between classmates?" Tang Zifeng was stunned for a moment and understood, it seems that Xiao is not without a little social experience, and he knows what it means to be Shengmien and Doumiqiu. There is indeed something wrong with her coming forward to ask the two roommates to help, and if you don't get it right, you won't even be able to be friends.

Tang Zifeng asked Xiao Wen to design this set of machine tools, which was aimed at the foreign market. According to Tang Zifeng's estimate, a set of machine tools sells for one or two thousand dollars, and one or two thousand sets a year is not a problem. If the sales force is a little bigger, it is not a fantasy to sell 10,000 sets a year.

10,000 sets of machine tools is more than 10 million US dollars of business, which is equivalent to hundreds of millions of yuan. Xiao Wen takes 1% of the patent licensing fee and also has an income of millions. So, the question arises, if she asks her two roommates to help in the process, how much will she give to the two roommates in the future?

According to the general cost standard for students to work, even if Xiao Wen pays 10,000 yuan each to his two roommates, it is a sky-high price, and the allowance for graduate students is 300 yuan a month, plus some labor fees from the tutor every other day, a graduate student can earn 6 or 700 yuan a month, even if he is a successful family on campus. Xiao Wen asked his roommate to do some work, and he was paid 10,000 yuan in two or three months, which was shocking enough.

But even so, once the roommates know that Xiao Wen is getting 100 times that income, it may be difficult for them to maintain their psychological balance. They may even wonder if Xiao Wen has exploited their cheap labor and offered them a good price for what they have made, while giving them a fraction of it. At that time, all kinds of contradictions will appear, Xiao Wenfei will not only be unable to be a person in the dormitory, but his bad reputation may even spread throughout Tsinghua University.

Considering these consequences, it would be wise for Chauvin not to ask his roommates to help.
