Fortunately, the food was delivered at this time, and Xiao Wenjun's attention immediately turned to the dining table. Without even saying politely to Tang Zifeng, she began to put down her chopsticks. It seemed that she had said she was hungry before, which was not a lie.

The two of them had a tacit understanding and did not hold each other to show their affection like the young couple at other tables. This was also a kind of style of the children of the world.

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

Xiao Wenjun said: "I was a little optimistic about the workload before, and I thought I could design the machine tool alone. Now it seems that this task alone may not be completed. I don't know if you can ask the technical department of Pinyi Machine to help."

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

Xiao Wenjun said: "It's mainly about computing. My heart is a bit big. I hope this machine tool can process steel with lower strength, so that the stiffness requirements for each part of the machine tool will be improved. This machine tool must be installed in a tool box, which determines that the bed, support and other parts cannot be too thick. To increase the stiffness, special steel must be used, which will lead to a significant increase in costs.

"I am now considering that I need to comprehensively process the stress conditions of the computer bed under various materials conditions, and determine what kind of materials can be used to ensure the rigidity requirements and maximize the cost savings. This calculation is very large, and there are too many factors to consider. If I do it alone, I may not be able to complete it in less than half a year."

The mini machine tool that Tang Zifeng envisioned will certainly 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. Many industrial enthusiasts abroad will buy such machine tools and put them in the garage, occasionally used to make small toys to satisfy their production habits.

Because the machine tool is very small and for the need to "play with cool", all the components are fortified into a tool box, so as Xiao Wenjun said, the bed, arms and other components cannot be made very thick, and will deform under heavy stress. Therefore, this type 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 said to Xiao Wenjun in advance.

But Xiao Wenjun is a person who likes to challenge herself. She wondered whether this kind of machine tool can have some practical value besides being a toy? For example, if a small part at home is broken, the owner can use this machine tool to process a part to replace it, so that the value of the machine tool is much greater than before.

Some of the parts used at home are made of steel, and of course they are generally not high-strength steel. Ordinary steel is enough to use. Xiao Wenjun's idea is to increase the structural stiffness of this mini machine tool so that it can process ordinary steel, which greatly increases the design workload.

Tang Zifeng now has some industrial knowledge. Xiao Wenjun explained it briefly to him, and then he understood what was going on. He thought for a while and said, "Your idea is good. Using different materials, the application scope of machine tools is also different. I can divide the machine tools into several grades, which can only process wood, aluminum, and ordinary steel. The prices of each grade are different. The highest grades are sold to local tycoons, and the price is 10,000 US dollars, without bargaining."

"This is too exaggerated, right?" Xiao Wenjun smiled. "I have probably calculated that a set of such a machine tool will not cost more than 2,000 yuan, which is less than 300 US dollars. Even if you use special steel to make the bed and arms, it will reach the top of the bed with 1,000 US dollars. Why can you sell 10,000 US dollars?"

Tang Zifeng said seriously: "First of all, your algorithm must be problematic. You said that the cost of machine tools is low, just because you calculate it based on the labor costs in China. If it is replaced by labor costs abroad, how much labor will it take to make these small parts? In addition, what we sell is not just manufacturing costs, but also a creativity, and it is not worth $5,000?"

"Others can do this idea, too," said Xiao Wenjun.

Tang Zifeng said: "So we must hurry up and apply for a patent. This machine tool is considered a utility model, right? As long as we register a patent, people need to consider it if they want to imitate it. In the domestic market, it doesn't matter how those counterfeit companies want to imitate it. Anyway, there will be no local tycoons in China who can afford such a machine tool."

"The main thing is that the rich man doesn't need a machine tool." Xiao Wenjun smiled and corrected him.

"Why did I hear a rich man say that he wants to buy one?" Tang Zifeng looked confused, as if recalling which rich man said this.

Of course, Xiao Wenjun knew that he was sarcasticating himself, because she was the one who said she wanted to own a set of such a machine tool, and she was indeed one of the rich.

In the past year or so, Tang Zifeng and Xiao Wenjun have jointly developed many new products. Each new product was proposed by Tang Zifeng and implemented by Xiao Wenjun, and then sold the patent to Pinyi Machine for production. Although those small products were not as popular as before, they also created income ranging from hundreds of thousands to millions for Pinyi Machine. Accumulating a small amount of money, these products were still very helpful to Pinyi Machine.

Linyiji and Xiao Wenjun maintained a tacit understanding, and each new product would pay Xiao Wenjun a certain proportion of patent licensing fees. After a while, Xiao Wenjun became a rich woman with a net worth of millions. Of course, this matter was limited to a very small number of people, and Tang Zifeng was undoubtedly one of them.

Xiao Wenjun is not a person who pursues a luxurious life, but with money, his consumption concept will naturally change, such as buying a mobile phone for himself, buying a few more expensive clothes, and then sponsoring his parents to buy a luxury house in Wulang city. This is something that needs no need to say.

Every time Tang Zifeng met Xiao Wenjun, he always joked that she was a new local tyrant at Tsinghua University. Xiao Wenjun was a little resistant to this statement at the beginning. After a long time, he accepted it and felt that he was indeed a local tyrant.

When she heard Tang Zifeng talking about the rich again, Xiao Wenjun just pretended not to hear it and said, "The design of this machine tool is still a bit of skill, especially the integration of functions such as machine tools, milling machines, drilling machines, etc. is equivalent to many components that need to be adapted to different processing methods. For this, I have been using my brain a lot. Registering the design of these multifunctional components as utility models basically blocks the path of others' imitation. If others want to go around these designs, even if they can be realized, the cost will definitely be greatly increased.

"As for those small domestic enterprises, it will be more difficult to imitate this kind of machine tool. Most of the components of this machine tool are relatively small and require precision processing. I think those small enterprises do not have the ability to fine processing."

Tang Zifeng said: "It doesn't matter. As long as they don't take food abroad, I don't care how to imitate it in China. If I want to take food abroad, I will get a lawyer abroad to deal with them. I think foreign agents dare not act like a big deal and act on their infringing products."

Xiao Wenjun nodded in agreement, then returned to the original topic and said, "Then, there is only one problem left now. I need to find someone to do the subsequent calculations. I can provide the ideas, but the stress relationship between so many components is very troublesome to calculate, and I can't do it alone."

"Why didn't you expect to ask your classmates to help? I see that your two roommates are not...uh, I mean, they look stupid at first glance." Tang Zifeng was smart again.

Xiao Wenjun gave Tang Zifeng a blank look and said, "My two roommates, one is Liu Yidan and the other is Dong Xiao, are both girls with very lively personalities. I will introduce them to you another day. In fact, I have thought about asking them for help, but I haven't thought about the specific method. If it is not done well, it may affect the relationship between classmates."

"Influence the relationship between classmates?" Tang Zifeng was stunned for a moment and understood. It seemed that Xiao was not without some social experience. He knew what it means to promote Mien and fight Mi Qiu. It was indeed a problem that she asked her two roommates for help. If she couldn't do it well, everyone wouldn't even be able to do it.

Tang Zifeng asked Xiao Wenjun to design this machine tool, focusing on the foreign market. According to Tang Zifeng's prediction, it is no problem to sell a machine tool for one or two thousand US dollars, and it is no problem to sell a machine tool for one or two thousand units a year. If the sales force is a little stronger, it is not a fantasy to sell a 10,000 units a year.

Ten thousand sets of machine tools are more than 10 million US dollars in business, equivalent to RMB 10 million. Xiao Wenjun also earns millions of income with 1% of the patent licensing fee. Then, the question arises. If she asks two roommates for help during this process, how much will she give them to the two roommates in the future?

According to the general cost standard for hiring students to work, even if Xiao Wenjun gives two roommates a reward of 10,000 yuan per person, it is considered a sky-high price. The allowance for graduate students is 300 yuan per month. With some labor fees paid by the supervisor every now and then, a graduate student can earn 6,700 yuan a month, even if it is a successful student on campus. Xiao Wenjun asks roommates to do some work and pay 10,000 yuan in two or three months, which is shocking enough.

But even so, once the roommates know that Xiao Wenjun is getting 100 times the income she earns, it may be difficult for them to maintain a psychological balance. They may even doubt whether Xiao Wenjun has exploited their cheap labor, paid a good price for what they made, and only gave them a fraction. At that time, various conflicts will arise. Not only can Xiao Wenjun not be able to be a human being in the dormitory, but his bad reputation may even spread throughout Tsinghua University.
