"Zhang Chaoyang's Physics course" has been out frequently since it was broadcast for more than a year. Zhang Chaoyang, who has a doctorate in physics at MIT, often revolves around physics phenomena in popular social events, explaining in a profound and simple way that ordinary people can fully understand, and has stimulated the upsurge of science learning many times.

In the new issue of "Zhang Chaoyang's Physics Class" on May 19, Zhang Chaoyang made a hard-core analysis of Huawei's Mate X3 folding screen phone with high technology. It is worth mentioning that as early as March this year, at the launch of Huawei's Mate X3 folding screen, Zhang Chaoyang attended as a special guest and deconstructed and shared the large screen experience of Huawei Mate X3 with physics.

After all, it is also the first deep user of Huawei Mate X3. This time, Zhang Chaoyang once again explained in an easy-to-understand way the application of "non-Newtonian fluid" on Huawei Mate X3, as well as the technological innovation behind the new generation of double-rotating water drop hinges.

Huawei Mate X3 flagship folding screen phone is the seventh folding screen phone launched by Huawei. Adhering to the deep understanding of folding screen phones, Huawei Mate X3 brings a breakthrough in the thinness of folding screen imagination, the extremely thin thickness of folded 11.08mm and expanded 5.3mm, and the extremely light weight of 239g of plain leather and 241g of glass is almost the same as that of a flagship phone with a straight plate with a shell.

In the most fragile folding screen, Huawei Mate X3 has brought hard core innovation-Huawei Mate X3 outer screen uses ultra-reliable Kunlun glass, which is widely praised by users, so that the ability to withstand falls is enhanced to 10 times, so that it is truly unafraid of falling and ultra-reliable quality. The inner screen is the first screen composite laminated structure and uses the industry's first non-Newtonian fluid material. Compared with the previous generation Mate X2 inner screen, the impact resistance is improved to 4 times, making it easy to cope with a variety of use scenarios and environments.

In this open class, Zhang Chaoyang focused on the analysis of the Mate X3 industry's first "non-Newtonian fluid" anti-impact inner screen.

The first is "non-Newtonian fluid". Non-Newtonian fluid widely exists in life, production and nature, such as blood, starch and so on. It is a kind of fluid that does not meet the experimental law of Newtonian viscosity. When the shear thickening non-Newtonian fluid is impacted, the relative motion between the particles in the material will occur, but due to the shear thickening, these relative movements are limited, and this limitation spreads from the impact point around, thus absorbing the impact energy. shows a strong anti-impact ability.

Inspired by "non-Newtonian fluids", Huawei Mate X3 adopts non-Newtonian fluid materials based on dynamic chemical bonds with ultra-high energy dissipation capacity of millions of molecular weights and hundreds of millions of ultra-high density (chemical bond density), which can not only achieve smaller size, but also enhance the shear thickening ability of materials, achieve stronger energy absorption capacity, and improve the energy dissipation capacity of materials.

Zhang Chaoyang introduced in the open class that when the external force bends, the external force is very small, and the energy required for dynamic chemical bond separation is small, so the material is soft and easy to bend. When the impact is received, that is, when the stress is suddenly increased, the energy required for dynamic chemical bond separation is large, so the material is hard and not easy to deform.

Therefore, based on the above advantages, Huawei Mate X3 has a fourth power relationship between energy absorption capacity and impact speed, and the impact resistance of the inner screen is four times that of the Mate X2, which brings the strongest anti-impact performance of the inner screen of the folding screen.

Another core cool techs of Huawei Mate X3 is a new generation of double-rotating water drop hinges, which is one of the reasons why Huawei Mate X3 can be so thin and reliable. In this open class, Zhang Chaoyang first focused on the topic of "hinges" and popularized science about the advantages and disadvantages of "U-shaped hinges" and "water drop hinges" that are common in folding screen phones on the market. Zhang Chaoyang believes that the water drop hinge carried by Huawei Mate X3 directly drives the door panel through the main movement of the arc arm, on the one hand, the number of key parts is smaller, the overall size is smaller, on the other hand, the movement path is shorter, the opening and closing accuracy is higher, and finally in the weight, thickness, experience of multiple optimization, not only will not appear creases and creases, this will not only be more beautiful, but also will extend the service life.

In terms of material innovation, Huawei Mate X3 uses aviation grade 700MPa high-strength aluminum alloy, which has higher requirements for strength, hardness, toughness, fatigue resistance and plasticity. Its strength is comparable to that of ultra-high strength martensitic steel, but its density is only 1x3 of steel, which not only meets the reliability of hinges but also meets the requirements of ultra-light weight.

As early as Huawei Mate X2 has been launched with the "water drop hinge", achieved a seamless, flat use experience. Equipped with double-rotating water drop hinge technology and aviation-grade aluminum alloy material Huawei Mate X3, compared with Huawei Mate X2, the weight is reduced by 26% and the thickness is reduced by 25%, bringing a new experience of ultra-thin, ultra-reliable and smooth opening and closing.

In addition, the "good handle" of folding screen phone opening and closing is also a knowledge. Zhang Chaoyang said that the torque on both sides of the hinge at different angles is different, so the corresponding force curve can be fitted according to different angles. Huawei engineers accurately calculate the opening and closing force of different angles in the opening and closing process by considering a variety of factors in the opening and closing process, and finally tailored the optimal opening and closing force curve of Huawei Mate X3.

Taking Huawei Mate X3 as an example, Zhang Chaoyang has extended a lot of knowledge around the topics of "non-Newtonian fluid", lightweight structural design, and the application of scientific and technological innovative materials, and viewers also have a deeper understanding of Huawei Mate X3 in this hard-core science popularization.

There are many "cool techs" on Huawei Mate X3. For example, in terms of communications, Huawei Mate X3 is equipped with an upgraded version of the two-way Beidou satellite message function, which can not only send smooth connection messages to the outside world, but also receive responses from the outside world without ground network signals. In extreme circumstances, you can double sense of security. In terms of basic communications, Huawei Mate X3 has even ushered in a major upgrade: the first launch is equipped with a telepathic communication technology solution (Huawei P60 series synchronous launch), which fully taps the potential of communication signals through telepathic antennas, telepathic networks and telepathic algorithms to ensure that users have high-quality and smooth signals at all times. For example, in the image part, Huawei Mate X3 uses super-perceptual XMAGE images to build a new height of the folding machine, which is equipped with a 5000-megapixel super-sensing camera, a 1300-megapixel ultra-wide-angle camera, and a 1200-megapixel telephoto camera, which has the strongest telephoto ability of a 5x optical zoom and folding screen phone, and the unique RYYB super-sensing image unit is added, and the amount of light input is increased by 40%, showing excellent image performance.

It can be said that Huawei Mate X3 is extremely frivolous and also decathlon, bringing a subversive all-around experience and completely subverting the public's imagination of folding screens.
