Last year, Motorola Mobility, which was still a subsidiary of Google, announced the Projectara modular phone program, preparing to produce a new concept mobile phone that is completely modular and can be freely combined.

At the beginning of the year, when the latter was sold to Facebook for less than $3 billion, the PA project was retained along with Motorola's patents (only 2,000 were sold, and more than 20,000 patents were only licensed), and the first version of the development module was recently launched.

The core of the PA mobile phone is a sturdy metal frame, the front is installed with a whole touch screen familiar to the public, and the back is a lattice, there are metal contacts in the lattice, and the CPU, memory, flash memory, camera, battery, and sensors and other necessary components are packaged into a small piece similar to mosaic tiles, and they are placed on the lattice on the back of the mobile phone according to their size, and they are assembled into a new mobile phone, and the back of those "mosaic pieces" is the back cover of the mobile phone.

The mosaic module and the mobile phone frame are not connected by conventional methods such as hot melt adhesive, screws, clip locks, etc., but are connected by electric permanent magnet technology. So they're actually tile modules that are more "magnetic" than the Metro tile user interface on Microsoft Windows 8.

However, the tile interface is made up of rectangular tiles of different sizes and functions, and the "adsorption" between them is a complete software problem, and only the coordinate algorithm needs to be set to connect and align well, while Google's engineers overestimate the electric permanent magnet.

An electric permanent magnet is an emerging permanent magnet that is composed of two strong magnetic materials and controls the internal magnetic circuit through a chip, so that it can switch back and forth between the "magnetic state of strong combination" and the "non-magnetic state of internal friction canceling".

After Google disclosed this plan, Bee, which was developing a modular smart bracelet at that time, also immediately set its sights on electric permanent magnet technology and made some preliminary attempts, and the effect can only be said to be quite good.

The use of electric permanent magnet switches can indeed be well connected to the broad bean module of Zhizhu, but the cost is a bit high, but the final production version did not choose this technology, but used the traditional lock connection, that is because the test at that time also found that the adsorption force of the electromagnetic link is slightly low, and even a four-month-old baby can reach out and pull one off.

The trial version of the wisdom beads worn by Tang Jiayi on her wrist is magnetically linked, and you need to pay attention often not to let the little ones at home stretch out their little hands to them, otherwise it will be the rhythm of the big beads and small beads falling on the jade plate.

Well, it's all to blame for these wisdom beads being made so beautifully, candy-colored, shiny, and delicious.

Although I haven't seen the real thing, Atletico Madrid has every reason to worry about its body bones for the pamobile phone, it is likely that it will not fall, and it will fall to the ground and fall into parts, although this will help absorb the impact energy to avoid breaking the screen, but everyone should not like it.

The current Bee 5D is the result of their experience in the PCDIY industry, just like a mobile phone-like PC compatible machine.

If you remove the back four screws and remove the back cover, the back of the 5D is still a little similar to the PA, and these functional modules are also made into small pieces, which are inlaid and stacked on the mobile phone motherboard like a mosaic. The appearance of different modules is very different, and there is no unified package, and at the same time, the back and motherboard are printed with patterns and words representing various functions, and you can install them when you find the corresponding mounting point.

This "motherboard" is the originality of the bee, and the PC motherboard is different, all the components of the mobile phone are soldered on the motherboard, it is very troublesome to replace and disassemble, the motherboard of the bee 5D is equivalent to a reversal of history, the mobile phone motherboard is divided into independent pieces according to the function into an optional and replaceable functional module, and the 5D motherboard is only left with the circuit and screw holes for connection.

The domestic mobile phone giant ZTE also released a modular mobile phone with a similar concept last yearEco-touch, which puts the internal components of the mobile phone into the battery unit, core unit, camera unit and screen unit, and the small unit can be easily installed and removed through the slide rail, which is very technological and design-oriented. As a result, the former was awarded the Red Dot Design Supreme Award in Germany in September last year, along with 48 other designs from various industries.

However, the mobile phone is positioned as a concept machine for the exhibition, and the CPU memory flash memory is encapsulated in a plastic block and installed with slide rails, although it is cool, but it has no practical value for the time being, and ZTE has no plans to launch this mobile phone. On the contrary, the DIY series that the bees use glue and screws to install and fix is more valuable for mass production promotion, but it looks a little low, but fortunately, these are firmly blocked by the back cover, which is nothing.

As for the problem of complicated operation, in fact, it is not serious, it is just chopped and reorganized on the basis of ordinary mobile phones, users only need to choose the specifications and whether to install, as long as the hands-on ability is not too bad, with the help of supporting tools can be completely done.

Of course, this also restricts the degree of freedom of DIY, and the installation location of each module cannot be decided at will, but fortunately, they are not limited to death, such as camera, headphone jack, side button, data interface, MSD card slot, etc., and the modules closely related to personal habits have four connection points, which can be used according to habits, of course, you can also create a wonderful personalized model that is used all or not at all, but in this way, there will be some trouble if there are more functions and fewer functions.

It is also for this reason that the most of the 5D accessories are not all kinds of high and low mobile phone accessories, but the middle frame and back cover of various different openings have their own mold factories and precision machining centers, which is so capricious.

Coupled with a variety of optional materials such as metal, plastic, fiberglass, and a variety of background colors, the number of varieties of shell accessories is of course a lot, which is still not calculated as a result of the back cover pattern. If you count them, the number of back cover accessories would have to be multiplied several times.

In this sense, the Bee DIY series is not really a modular phone, but more like a phone that allows users to deeply customize the case interface. In the past, the customization of mobile phones was only to replace the pattern and material of the back cover, but in 5D, you can further choose the position and material of the headphone jack, MUSB port and volume shutter power supply, etc., and the degree of customization is undoubtedly more in-depth. Coincidentally, at the beginning, Google's PA plan also appeared as an upgraded version of the Tomaker mobile phone customization business.

As for the launch of more independent packages that can replace and upgrade functional modules, or open source hardware like Google for others to participate, Atletico said that there is no such plan for the time being, and the current two sets of high and low accessories should be enough.

Mobile DIY culture needs to be cultivated, and it's obviously a good idea to start with face-saving shell customization.

The more accessories, the more troublesome it is, if the mobile phone DIY finally becomes a profiteer's paradise like PCDIY, and it will be nonsense to get a bunch of pit goods like "4GDD ultra-large capacity video memory GT610 mad bull version graphics card". Therefore, Bee does not have a plan to open up all the hardware for the time being, but is only preparing to open the interface specifications including the headphone jack, private M card slot and the back cover of the middle frame, and the internal module is not going to be open for the time being.

And even if it is open now, there will not be many manufacturers interested in producing DIY series, but it can be remodeled and turned into a "bee compatible machine" to grab business for 5+ and 5 fans, which is funny.

With the increasing influence of the bee system, completely sitting on the throne of the third largest mobile phone system, gradually mobile phone manufacturers began to try to contact bees, trying to obtain authorization or ODM OEM cooperation, but they were all rejected, maybe someone will think of saving the country with the help of DIY project curve.

Now the configuration war of the Android camp and the price war are becoming more and more intense, and flagship mobile phones have been developed and launched one after another, and as a result, they have been eliminated and discontinued in the past few months, and if the sales volume does not reach the explosive model, it is likely that even the R & D cost will not be recovered.

The majority of the profits of the entire mobile phone industry were taken away by Apple, and the small heads were divided by giants like Samsung and Microsoft.

Of course, Android manufacturers also have two incomes: app store distribution share and application pre-installation fee, as long as the phone sells enough money, it won't lose money at all. Only those manufacturers who insist on independent research and development but whose sales have never been able to rise will lose money, such as the huge hard in the future.

Before the acquisition of Nokia mobile phones, Juhard through its WiFi, 3G, 4G and other communication fields, as well as the operating system field of ExFAT file system, RDT remote desktop protocol, EAS email synchronization protocol, soft keyboard input method, stylus input method, as well as H264 decoding in the video field of hundreds of patents, can get about $10 per mobile phone from Samsung, HTC and other Android manufacturers every year, according to the sales volume of this income is enough to exceed $1 billion per year.

Of course, most of the domestic mobile phone factories are not very hard, and those who pay patent fees are brands that go overseas for sale, and they are afraid that Microsoft will launch a patent lawsuit to ban sales, and they can't afford to pay the patent fee of 60 yuan for a machine. This is not like Qualcomm SoC's patent fee is not easy to escape, if you don't pay the patent fee honestly according to the price, you won't ship the goods, Microsoft is a company to talk about it, and only those big factories need to pay at present.

However, the bee was already approached by Microsoft when the annual production was only a few million units, and it began to ask for royalties after the acquisition was rejected at the beginning. Then after difficult negotiations, Atletico Madrid had to pay a huge patent fee of 30 yuan for every mobile phone sold, which is why he stopped the small watermelon thousand-yuan machine and launched a cheap rental plan as a replacement.

Now that the giant hard has collected the little demon of the younger sister (Lu Mi A), Ma Dong can try to cut the price, because he is good at cracking and integrating, the bee has really accumulated a lot of useful patents in recent years, plus the patents acquired at home and abroad, the bee's own patent wall is also considered to have some height and thickness. In this way, everyone can put out their own patent pools with each other, I need what you have, I need what you have, you also need it, then just cross-license each other, and everyone doesn't have to pay patent fees!

In fact, before this, Ma Dong had already found some "return money" from Microsoft, and that was because Microsoft followed the popular trend of "voice control" and also launched a personal voice assistant function.

Although Giant Hardcore specifically named their voice assistant after Cortana, the AI character of the 2001 game Halo Holo, that doesn't change the fact that it's the fourth voice assistant app among the four major mobile phone systems. At that time, the world's first usable and so far the best voice interaction system happened to be the bee's Yiqiu (Yiqiu), in fact, not only Cortana had to pay protection money to Yiqiu's big sister, but Apple Xiaori (private day) also had to pay a fee. The worst is GoogleNow, not only has to pay, its market share in the wall is also completely occupied by Yiqiu big sister, the latter is not only the bee platform is the most popular voice control application, but also the most popular on the Chinese Android platform, the only drawback is that the internationalization is not very good, and the support for small languages is not strong enough.

Speaking of which, what can really be regarded as "core technology" in Atletico Madrid's hands is carbon nanotube application technology, artificial intelligence technology, speech recognition synthesis, virtual reality, etc., but these technologies are too advanced and seem a little ungrounded. Although bees are leading in the field of AI and voice, they have not reached a monopoly and can't collect much money, and the field of virtual reality is at the hegemon level, but unfortunately this industry has not yet developed, and it still can't collect money.

As for carbon tube technology, what makes Atletico laugh and cry is that their release of C1 mobile phones and registration of carbon tube application patents have actually delayed the development of carbon tube application technology, because he has boosted the seedlings. The application technology of the carbon tube of the bee is indeed advanced, but it is a special case that is out of the technical conditions, and the direct research from a high starting point to crack them will lead to a weak foundation, and eventually it will be like the domestic engine industry to produce all kinds of cups. In this way, it may be impossible for anyone to make a production version of the C1 in a few years or so, and Atletico Madrid will naturally not receive royalties.

It's just that he only learned about this situation after reading foreign papers and reports, and it was too late to regret it, but fortunately, most of the patents were still in his hands and not thrown out. In short, the international R&D investment in the direction of carbon tubes has increased greatly, while the ban on silicon wafer technology has loosened a lot, and in the past 14 years, two 28nm wafer factories have been built, and even 16nm technology is being negotiated.

Ma Dong is tantamount to contributing to the country crookedly, which also makes him feel more at ease that the bee brand security system is so expensive. For mobile phone users, please visit http://m.piaotian.net
