After Lin Wenzhou and Lin Siqi left, Xu Zhi thought about the evaluation of the Rubik's Cube in later generations.

Among the many rebirth novels at the starting point, many of the introduction of the Rubik's Cube are among the most profitable toys in the world, in fact, this statement is not entirely correct, at least the profits of the Rubik's Cube in history are not as good as many toys.

The history of the Rubik's Cube dates back to 1974, when Professor El Roubick of the Budapest School of Architecture created a three-dimensional tool to help students enhance their spatial thinking skills, but it was initially only so, although it was patented in Hungary itself, but not internationally.

Theoretically speaking, if Xu Zhi runs to apply for an international patent at the moment, he can also seize the opportunity, but although this kind of thing has a law, it is unreasonable, if it is a small person who makes a lot of money, it can be operated, but if the company develops to a certain degree of popularity in the future, this kind of thing will be a black history, rather than spending a lot of effort to clean it up in the future, it is better to spend a little money now to do things right, not to mention, Professor Rubik invented such a thing, he should be rewarded.

In the first three years, the Rubik's Cube was not very mature and difficult to turn, so it did not attract much attention, and it was circulated in schools as a tool to help students until 1977, that is, last year, when local merchants tentatively made this product into toys and sold them in toy stores in Budapest.

In fact, it began in September 1979 that the Ideal Toys Toy Company (the parent company of Teddy Bear) from the United States bought the patent of the Rubik's Cube, and in January and February 1980, it was unveiled at the Toy Fair in Paris and New York respectively, which unveiled the global road of the Rubik's Cube.

However, even if it was an instant hit, in the next 80-82 years, in almost two and a half years, a total of 2 million Rubik's cubes were sold around the world, even if one Rubik's Cube earned $2, the net profit was a total of $4 million.

This may be a good amount for a small company, but compared to Transformers, 4WD racers, cauliflower dolls, Barbie dolls, etc. in the same industry, this distance is definitely not half a star.

Of course, this is actually because the promotion of the Rubik's Cube in history was not strong enough at the beginning, and if Xu Zhi operated, then the sales would definitely increase exponentially.

And the Rubik's Cube is actually the same as Tetris, the victory lies in strong patience, the annual sales are so stable, and even the longer the time, the higher the sales, and after the Internet era, the spread of online video has popularized the rotation principle of the Rubik's Cube, which can be regarded as a stable cash flow, but it can't break out at one time.

With the Rubik's Cube, it's not just for the money, but for its huge fame and reputation for the positive energy of thinking toys that is recognized in the field of international education.

The Rubik's Cube, together with Huarong Dao and Independent Diamond Chess, has been called the three incredible minds in the world of intellectual games by foreign intelligence experts, and the popularity of the Rubik's Cube is a miracle in the world of intellectual games.

The Rubik's Cube is very playable, and countless TV programs in later generations have held Rubik's Cube competitions, and there are many varieties: racing gameplay, minimum step competition, blind twisting, one-handed twisting, and foot twisting.

And the follow-up derivative products will also involve the fourth-order Rubik's Cube, the fifth-order, the sixth-order....... until the seventeenth order, of course, for ordinary people, the fifth-order is basically the limit, and the follow-up ones are purely mathematical research.

If you get the patent for the Rubik's Cube, you can first hype up the product and then hold a Rubik's Cube competition on local TV stations to encourage players to participate with huge prizes, which can not only increase the popularity of the Rubik's Cube, but also stimulate sales, and at the same time develop a certain degree of cooperation with many TV stations.

......

Midea Electronics Company recently underwent a major internal change, He Guoyuan personally recruited a team specializing in the research and development of household appliances from Wanwan, a total of 15 people, and established the Midea household appliances department with them as the core.

These people are all through the headhunting company, spent a lot of money from the Panasonic (bending) branch directional digging, are all research and development of refrigerator technology professionals.

Cao Lizhong is one of them, he was originally the technical director of the refrigerator department of Panasonic in the Wanwan branch, although the position seems to be very high, but the per capita salary of the Wanwan at the moment is extremely low, compared to Xiangjiang is a lot worse, although his ability is much stronger than some RB local engineers, but the salary is only one-tenth of the RB intern.

Originally, there was no way to do it, until half a month ago, the headhunting company informed him that a Xiangjiang company intended to set up a household appliance department, and the salary offered was not only 5 times the current salary, but also free food and accommodation in Xiangjiang, and living allowance, and there were a few days of vacation every month to go back to the bend, and at the same time, the round-trip air ticket would be reimbursed.

So, after several interviews, he managed to beat a group of other interviewers and got this opportunity.

The R&D department is all together, of course Xu Zhi, the boss, has to show it, but unlike arcade games, it is useless for him to participate in this kind of technical meeting in matters like refrigerators, as a boss, he does not need and does not want to participate in too many of the following things.

Of course, Cao Lizhong is the chief engineer of the refrigerator department, and Xu Zhi still needs to have some communication with him alone.

"Xu Sheng, hello!" Seeing Xu Zhi come in, Cao Lizhong stood up and greeted in broken Cantonese.

Xu Zhi smiled and said in standard Mandarin, "Mr. Cao is not welcome. ”

When Cao Lizhong heard Mandarin, he was stunned for a moment, and said: "I didn't expect Xu Sheng to speak Mandarin, which is not common among Xiangjiang locals." ”

Many people in Xiangjiang speak Mandarin, but they are all people who have migrated from the mainland, and those who grew up in Xiangjiang do not speak Mandarin, and few can understand it.

Wanwan's words are actually similar to Mandarin to a certain extent, although they are different, but they can understand each other's meanings and communicate directly, which is much stronger than Cantonese in Xiangjiang.

Xu Zhi smiled: "I know a little, when I was a child, I knew some elders from the mainland and learned from them." ”

"I see. Cao Lizhong didn't care too much.

Xu Zhi asked, "Can Cao Sheng get used to life in Xiangjiang?"

Cao Lizhong said: "The material aspect is much stronger than the curve, but the pace of life is too fast, and the speed is a little unaccustomed." ”

Xu Zhi smiled: "This is not a problem of Xiangjiang, but it is the same in all big cities around the world. I'm afraid it's the same in Taipei. ”

Cao Lizhong smiled: "That may mean that I haven't been in a big city!"

Xu Zhi asked: "Regarding the company's refrigerator business, I don't know what Cao Sheng thinks?"

Cao Lizhong replied: "It may take half a year to make a sample. ”

Xu Zhi asked: "It takes so long to develop and develop, and there should be few patent restrictions on refrigerators, right?"

Cao Lizhong said: "The theoretical technology of the refrigerator has appeared for hundreds of years, of course, there is no patent, but the internal structure of each company is also its own patent, we can't directly buy a copy of it, it is actually easy to make a refrigerator, but it is very difficult to do it well."

To put it simply, the outer size and internal space of the refrigerator actually have a certain proportion, the higher the proportion, the better the utilization rate of the refrigerator, which involves the structural system of the refrigerator.

The refrigeration system Xu Sheng should also understand that the refrigeration speed of the refrigerator and the uniformity of the air conditioning in the internal space also involve the power consumption and heat dissipation of the refrigerator.

There is also the electrical system, which involves the electrical safety and service life of the refrigerator.

These things do not exist independently, but are interrelated, and in order to do everything to the best of it, this aspect must be tested step by step. ”

Xu Zhi asked, "What about the air-cooled refrigerator?"

Cao Lizhong said: "The air-cooled system is more complex, I don't recommend direct research and development, in fact, now the air-cooled refrigerator can also be made, after all, the principle is known, but the parameters will definitely be much worse than the brand in the market." ”

Xu Zhidao: "I didn't expect it to be so complicated! Then let's develop an ordinary refrigerator first!"

Cao Lizhong shook his head and said: "This is just the beginning, there is a whole set of drawings to draw in the follow-up, the preparation of production processes and material types, tooling and mold development, etc., and then the samples come out, and there will be trial production after they come out, etc., but the production is not realistic on the Xiangjiang side, and the industrial conditions here do not meet." ”

Xu Zhi smiled: "Okay, I'll be responsible for the follow-up, Cao Sheng only needs to be responsible for developing the product." ”

Cao Lizhong promised: "No problem, after half a year, I promise to give Xu Sheng a complete refrigerator!"
