The Circular-Centerpiece 3x3 · 模型 19875
So… I’m a competitive speedcuber. I solve Rubik’s Cubes really fast. A big part of this hobby is hardware; you have to have cubes that can move as fast as you can turn it if you’re going to be very quick. Over time, there have been countless designs, the first being from Rubik’s, but most being from other manufacturers, such as Moyu, Qiyi, Yuxin, Dayan, and many more. The speedcubing marketplace is very interesting because of the number of companies designing better and better cubes to try and come out on top of all the others. New cubes are iterated very quickly, with a new 3x3 (the standard size of puzzle) coming out at least once a month. Most of these cubes use almost the exact same mechanism to achieve their smooth turning and cornercutting (the ability for the cube to cope with slightly misaligned layers), with just changing the profile of the puzzle a little (we’ll get to what that means later). This means that all the current cubes on the market, unfortunately, have some of the same problems. One of the main problems that my design fixes is spring noise. In other cubes, every piece on the face of the cube turns with the move, including the centerpiece. Inside the center, there is a screw, threaded into the core, that has a spring sandwiched between the head of the screw and the bottom face of the centerpiece. This spring allow the centerpiece to move away from the core a little, but be pushed back, and is very important to the cornercutting of the cube. The problem is that the centers are square, to fit in the grid, and it has to turn with the face. This means that the spring has to rotate against at least one of the faces it is contacting (the bottom face of the centerpiece or the head of the screw). This motion makes a ping-ping-ping sound as you turn the face, and that becomes really annoying. This problem can be mostly mitigated by putting small washers on those surfaces, and by lubricating it, but it is hard to completely get rid of. So what’s the solution? My circular-centerpiece design solves this problem simply by not having the centerpiece turn with the face. The centerpiece is just a rotated profile, which allows the face to turn around it. The core has some prongs on it to make sure the centerpiece and the core don’t rotate relative to each other, while still letting the center slide out a little. This design also keeps the pieces in the cube a bit better than other designs, which is a problem on some cubes. In the speedcubing commu...
