After saying so many words, Zhang Ruimin was already a little thirsty and was about to take a drink of water, but the audience still burst into warm applause, because Polaris Company is indeed as Zhang Ruimin said, its products are not only first-class in industrial design, but also have Many pioneering products, such as the previous LCD screen, are simply of epoch-making significance.
Although other products do not have epoch-making significance, they are still at the top level in the same industry. Regardless of whether they are epoch-making significance, as long as they can achieve the top level in the same industry, they are a company worthy of respect.
The two products announced at this conference are also groundbreaking.
Although the principle used by bladeless fans is not new, Polaris has applied this long-standing technology to a small fan, making a sparse and ordinary fan completely different.
Not only does it have the power-saving and silent effect, but it is also safer than a blade fan, which is especially important for people with children at home.
Don't underestimate this small fan. Its technical content is not low. In addition to using turbocharging technology, the most difficult thing is the mute effect. In order to achieve an almost silent effect, Polaris Company has made a lot of effort in the rotating motor. A lot of effort.
No matter how you operate an ordinary motor, it will make a relatively loud noise, especially as the use time increases, the mechanical sound will become louder and louder.
In order to solve this problem, a magnetic levitation non-contact electric motor was finally used. An induction coil is used on the outside, which generates a strong magnetic field after being energized. The rotor in the middle uses a permanent magnet. The size of the electric power changes the size of the magnetic field, and the strength of the magnetic field changes the strength of the rotor. rotation speed.
Although the principle is simple, if the rotor is not located in the center of the magnetic field during a power outage, then how to make the rotor return to the center of the magnetic field after power is turned on without causing obvious shaking? This is the real difficulty.
In order to solve this difficulty, Polaris Company also spent a lot of manpower and material resources, and finally achieved it through a force sensor, which is used to determine whether the rotor deviates from the normal position.
If it deviates from the normal position, it will only change the local power supply strength of the coil and change the local magnetic field to make the rotor return to the normal position.
So we also know that this coil is not a complete one, but is composed of dozens of micro-coils, so that each coil can not only cooperate as a whole, but also have the ability to change independently, and the force sensor must be sensitive enough, otherwise it will deviate Too much amplitude will cause mechanical damage to the blades.
In addition to the design of this working coil, there are also up and down static homing coils, so that the bladeless fan can maintain consistency in the vertical and horizontal directions during moving projects, which means that the rotor will not vibrate up and down due to movement. and shaking left and right, causing unnecessary mechanical damage and greatly extending the service life of the bladeless fan.
Only this kind of rotor structure without any contact can make the bladeless fan nearly silent. The little sound comes only from the sound of the fan blades cutting the air and the sound of the air flowing from the bottom.
Because the sound of this air flowing and cutting air is very small, if you don't listen closely, you can't hear it at all.
In addition to desktop bladeless fans, there are also ceiling fan products.
The fresh air system is actually an evolved version of the air conditioner. The air conditioner simply compresses and cools the outside air and sends it indoors, while the fresh air system has two air supply and air inlet channels.
The air supply channel can draw indoor hot air or cold air out of the room, which not only ensures the freshness of indoor air, but also achieves energy saving effects.
At the same time, the air inlet is equipped with an air filtration biomembrane. The filtered air can reach the highest dust-free level. This depends on what level of filtration biomembrane is installed.
This kind of biofilm does not have adsorption properties for dust, which means that you don’t need to worry about dust adhering to the film after long-term use. The dust will automatically fall off and fall into the dust box after being intercepted by the film.
In addition, this biofilm also has bactericidal ability, which is achieved through the biological tentacles at the back end of the biofilm.
When bacteria or viruses pass by, these tentacles will grab the bacteria and viruses, then destroy the protein structures of the bacteria and viruses, and reject the damaged bacteria and viruses as garbage.
In other words, this kind of biofilm has a double-layer structure. The front-end film has the function of filtering air dust, and the back-end film has the function of sterilization.
It can be said that the most expensive part of the fresh air system is the biofilm. Of course, the price varies greatly with different filtration levels.
The other parts are relatively simple, which is to detect the temperature and humidity in various places indoors based on the temperature and humidity sensors. Since it can only adjust the temperature and humidity, it has similar functions to the air conditioner, so I won’t go into details here.
After drinking the water, Zhang Ruimin walked to the stage again. There was another round of applause from below. He pressed it down with his hand to signal the audience to quiet down.
Zhang Ruimin said: “In addition to the fresh air system, we have also carried out industrial design on traditional air conditioners. Traditional vertical air conditioners are so big that they are not beautiful and take up space when placed at home.
So we have this cylindrical air conditioner, which is not only beautiful, but also occupies a small space and is lightweight.
This will change everyone's existing impression of air conditioners. How do we make it so light and compact without losing effectiveness? This is due to the turbocharging technology we use on the bladeless fan, which makes the wind stronger and farther away. Further, more efficient.
It also uses magnetic levitation motor technology to make this air conditioner quieter, and because it uses vertical air supply technology to balance temperature, the human body feels more comfortable. "
When Zhang Ruimin introduced the cylindrical air conditioner, the product was also moved to the stage of the press conference. When the audience below saw this air conditioner, they couldn't take their eyes away from it. It was simply a work of art of industrial design. For Polaris The company's industrial design capabilities gained a new understanding.
Now that the magnetic levitation motor has been invented, of course it needs to be used in a wider range of products. Just like this, the press conference assistant brought up a hair dryer.
Zhang Ruimin said: "Thanks to our breakthrough in magnetic levitation motor technology, this hair dryer also has a silent effect. In order to reduce the ducted wind sound generated by the air in the hair dryer, we also invented a special coating. This coating Coated on the inner wall of the hair dryer, it can effectively absorb ducted wind noise.
This technology is also used in bladeless fans, fresh air systems and vertical air conditioners, making these devices have good silent effects.
Using this hair dryer in the future, you will no longer have to worry about disturbing your neighbors or sleeping family members at home when you shower and blow dry in the middle of the night. Moreover, this hair dryer also has a negative ion generating device, which can make the air blown out carry negative ions, making your hair no longer Being charged also reduces the phenomenon of hair splitting and burrs. "
In addition to the high technical content of the motor, this hair dryer also has the high technical content of the noise-cancelling coating.
This is the latest product of Cornerstone Materials Company. The sound-absorbing paint was originally applied to the fighter jets developed by Star Express Company. However, it was favored by Polaris Company. Then Cornerstone Materials Company simplified the original sound-absorbing paint formula.
Although the effect is greatly reduced, it is more than enough to be used on a hair dryer. The original sound-absorbing paint must be classified as a confidential material and cannot be used in the civilian field.
As soon as Zhang Ruimin's voice fell, the press conference assistant demonstrated some usage effects on the spot. The whole place was so quiet that you could hear the sound of a needle dropping, just to hear how loud this hair dryer is.
The result was excellent. Only the audience in the first row could hear a faint sound. The audience in the back couldn't hear the sound of the wind at all. If they didn't see the assistant's hair being blown up, they wouldn't know whether the hair dryer had been turned on. .
This effect made the audience present not excited. Although the hair dryer is a small item, it is indeed the most commonly used household appliance in the family.
Ordinary hair dryers not only make a harsh sound, but also cause hair quality to deteriorate if you blow too much. This hair dryer solves all the pain points of ordinary hair dryers.
In fact, these products are all incidental products of this conference. Generally speaking, Polaris will not launch a conference specifically. After talking about these incidental products, Zhang Ruimin finally talked about the main product of this conference, which is the satellite navigation system.
He said: “I think most viewers coming to this conference mainly want to know about our satellite navigation system, so let’s start talking about our navigation system now.
First, let’s talk about the vehicle navigator. Our vehicle navigator is a map matching algorithm based on map geometric information, topological structure, statistics and fuzzy theory. On this basis, a weight matching algorithm is also added to integrate the geometric information of the road and the Vehicle direction information greatly improves the accuracy of navigation.
Of course, if some roads are not recorded, then we also have a real-time correction function, which needs to be turned on manually by the user. Our navigator turns this function off by default.
The corrected information data will be saved to the current navigator device by default. Of course, if you choose to upload relevant data, you can also do so. These data will be updated in all navigators.
The reason for this is the need to balance the contradictions between relevant surveying laws and road changes in each country.
We will first save the roads or landmark buildings uploaded by users to the data center in the local country. After being reviewed and approved by the local government, we will choose whether to update the navigator in the country or the global navigator based on the level of use. renew.
These are all needs to solve some short-term road changes. In fact, our navigation map already includes road-related information in all countries around the world, and your daily use will not be affected in any way.
In order to avoid the navigator being used in inappropriate places, we use a relative coordinate algorithm for the longitude and latitude coordinates of the navigator, which is inconsistent with the real longitude and latitude. This is to keep the surveying and mapping information of each country confidential. I believe Consumers can understand it too.
In addition, our navigator also has customized voice technology. No matter where you are, you can have the voices of your family or the people you miss always by your side. "(End of chapter)
