When did the mechanization process accelerate? The precision of the "calculation" in it is beyond your imagination

As we all know, the hallmark of human beings becoming "modern people" is to make tools.

From simple tool manufacturing, to the continuous exploration of the formation of complex and cumbersome modern machinery, after a complex and long process, the birth of some representative mechanical equipment has greatly accelerated the pace of industrialization, the most representative of which is the United Kingdom.

In the mid-18th century, the production technology of British handicraft factories could not meet the demand for mass production, in order to improve the production speed, in the 60s, the weaver James Hargreaves invented the "Jenny Machine" hand spinning machine, which improved production efficiency to a certain extent.

When more and more factories were located by the river, using water wheels to drive industrial machines, in order to solve the drawbacks of using animal power to drain groundwater, in 1705, the Englishman Newcormen invented the Newcormen steam engine, but this steam engine fuel consumption rate is extremely high, only suitable for coal mines.

In 1765, Watt made a major improvement over the Nucomen steam engine, inventing the condenser steam engine now known as the condenser steam engine, which reduced the rate of fuel consumption while marking the arrival of the first industrial revolution. In 1781, Watt created a rotary power steam engine, expanding the range of industrial applications.

In the late 19th century, electricity and electric motors began to enter the public eye, and the internal combustion engine was continuously improved to be used in large and small industrial activities.

In 1885, Karl Benz patented the invention of the internal combustion engine tricycle, marking the birth of the modern automobile;

In 1990, Porsche introduced the tiptronic transmission, which has the function of manual and automatic free conversion, and is the originator of the hand automatic transmission to date.

In the second half of the 20th century, sophisticated electronic machines gradually began to fill our lives and continue to facilitate our lives at a speed visible to the naked eye, such as cars and computer equipment that we can't leave at all.

With the progress and development of the economy and society, the demand for machinery has not only grown by leaps and bounds, but also the requirements for precision machining technology have become more and more stringent.

How to meet the increasingly tricky needs of the public is a problem that needs to be continuously solved by major brands. Among them, OPPO, the "green factory" that has been at the forefront of science and technology and constantly seeks breakthroughs and innovations, has brought us a new surprise on the new mobile phone Find N released on December 15 - it is its first folding screen product.

How to say that the folding screen mobile phone is generated? Is the era of information explosion, the user's demand for large screens surges, but the large screen one-handed operation is extremely inconvenient, how to ensure the convenience of the operation process, but also to take into account the sense of experience brought by the large screen, folding screen mobile phone came into being.

Although folding screen products are not new to us, there are always concerns about related products. For example, the appearance is not amazing enough, the feel is not easy to carry, the technology is not mature, and the folding marks affect the beauty...

Let's take a look at how OPPO solves the above problems, so that it is "good-looking and easy to use, and the folding screen is from early to commonly used".

First of all, from the appearance of the rendering, find N is different.

In order to achieve a two-way balance between large screen and portability, Find N for the first time defined the folding gold screen size of 5.49 inches on the outer screen and 7.1 inches on the inner screen, which not only ensures the portability of folding up and one-handed operation, but also ensures that the inner screen is expanded to have a flat-like immersive experience, realizing the perfect unity of touch and perception.

Of course, as a folding screen phone, as a user, my biggest concern should be whether the common creases of folding products have improved. The crease problem can be solved in two ways, one is to optimize the screen folding method, and the other is to use a material that is less likely to produce creases.

To this end, Find N two-pronged, through 4 years of polishing research and development, the use of the most complex process, the highest cost of folding screen water droplet hinge, in order to achieve increase the bending radius to reduce screen creases,

With the 120Hz mirror screen jointly developed by OPPO and Samsung, it has made the folding screen mobile phone with the shallowest crease on the market, allowing users to achieve a "zero-sense crease" experience.

From a technical point of view, OPPO from the N1 rotary camera light flip, to OPPO Find X dual-track periscope structure quietly rising, and then to the reel screen of the slow sliding of the continuous exploration and accumulation of experience summed up, Find N not only to ensure a smoother opening and closing feel, but also to achieve hovering, so that the mobile phone screen breaks through the two-dimensional space, to show users more possibilities, bringing a new experience.

In order to achieve the above goals, it is necessary to accurately control the power generated by the "hinge". Whether it is the opening and closing feel, folding marks, or taking into account the new experience of "large screen, hover, split screen", it is inseparable from the use of hinges, which is also one of the most eye-catching breakthroughs on Find N.

Compared with the U-shaped hinges commonly used in the industry, the water droplet hinges used by Find N are not only high in cost, complex in structure, but also more precise in process requirements.

In order to ensure that it is not affected by the hinge during the opening and closing process, Find N has undergone repeated grinding of the internal structure of the hinge to ensure that the crease is lighter, while adjusting the mechanical design of the hinge to achieve a perfect fit with the screen and hide the folding marks to the greatest extent.

In order to achieve the best effect of hovering, the cam in the hinge plays a crucial role, the upper cam connected to the screen will squeeze to the lower cam connecting the spring when the screen rotates, oppo design team continues to optimize the cam design,

By increasing the number of cams, the damping is increased, and more space is left for screen bending, and the perfect result is finally achieved.

With the hinge as the switch, Find N realizes the golden ratio of the size design, the traceless large screen experience, the silky smooth opening and closing feel, the new interactive hover mode, and the super durability, breaking the flashy virtual name of the folding screen mobile phone, and becoming a convenient folding mobile phone with practicality as the mainstay, the price of 7699 is really affordable.

OPPO reshapes the design aesthetic with a precision hinge structure, representing a new stage in the design of modern industrial machinery, which also shows that the brand's development and use of precision instruments has become a new trend.

In fact, such precision instruments around us are indeed ubiquitous, but also greatly affect our lives, the development process of watches is also a good example.

At the beginning of the 16th century, the Germans made the first clocks, which opened the era of mechanical watches, and the first hand-wound pocket watch was produced in 1770.

Because of the complexity of the workmanship, the watch became a symbol of the nobility, such as the familiar Vacheron Constantin, Longines and other representative "luxury" brands, which were born in the 18th to 19th centuries, and complex functions such as timekeeping and timing were also produced in this period.

By the beginning of the 20th century, watches gradually evolved into what everyone is familiar with now, but the price of mechanical watches remained high and did not enter everyone's daily life.

In the 1970s, as quartz watches entered the public's field of vision, electronic watches, fashion watches, etc. also continued to emerge with demand.

However, the increasing popularity of mobile phones has made the function of watches more and more reduced, and gradually become flashy decorations. Whether it is color or style style, they are close to the public aesthetic.

However, it is undeniable that the watch, as a symbol of status, while taking into account practicality, also highlights the social status of the wearer, and has always played an irreplaceable role.

In the face of the continuous impact of electronic products, it is also interesting to see how the watch will be fully innovative from the appearance to the core!
