Thanks to the unique design of the hinges, users can form a triangle by changing the direction of the screens. This is not the first patent for a clamshell phone with two hinges. It should be noted that the Chinese company TCL in 2019 unveiled a concept clamshell phone with three hinges. Samsung is one of the companies that has such an idea and has registered several patents in this regard.
Although the implementation of this design allows users to access larger screens, but on the other hand Increasing the number of hinges increases the likelihood of the phone breaking down and making it more complicated to build. High-priced clamshells are now on the market, and if companies start making dual-hinged clamshells, they will undoubtedly cost more than regular clamshells.
It should be noted that all clamshell phones on the market are based on vertical and horizontal mechanisms. Among the clamshell phones based on the vertical mechanism, we can mention the Galaxy Z Flip series of Samsung and Motorola Razer. On the other hand, the Galaxy Z Fold series and Huawei clamshell phones are based on a horizontal mechanism that opens and closes like a book.
Besides clamshell phones, we should not miss the roll-up phones. These handsets consist of several moving parts, among which we can mention the central axis of the cylinders, motors for display movement and sliding frame. At present, no company has been able to launch a phone based on this mechanism. There are no creases on the display of such phones and there is no space between the screens.
Finally, it should be noted that OnePlus has only registered one patent, and if you are familiar with this issue, you probably know that smartphone makers always have ideas. They file various patents, many of which never become a reality. But maybe in the near future, OnePlus will try its luck in this field with the introduction of a clamshell phone.
