CONGS DESIGN MeiYu 4x4x4 Speed Cube Black
Cong's Positioning System: Brand new positioning systme for even-number-layer cubes - - In terms of Meiyu, it made a string imperative optimizations on the basis of original East-sheen positioning systme of which thress import breakthroughs made the system more suitable for even-number-layer cubes having fine-tune springs systme.
Take apart a big cubic unit from a core of East-sheen into three independent 1/4 square platforms, respectively locking the spinning directions of middle layers.
As what you see from the following pictures, It decided to connect positionging accessories together by using this mechanism which bring an adavantage that the 4x4 cube is able to have elasticity between center pieces and the core, unlike routine 4x4 cubes. Thanks to this idea, when one of the six sides have to be spread while the cube is applying corner cutting, bottom positioning platform is able to be pulled up, meanwhile, positioning platform and the positioning units still have close relation to coordinate, highly improving the effect of positioning.
Arc convex pieces on the verges of positioning platforms, arc pieces on the bottom of center pieces and the bottom of hidden edges are for better and tighter biting between every unit of the positioning system, eliminating the phenomenon of 'dead lock-up' caused by various factors.
Big inner-track system makes the cube easily be distinguished from other cubes by owning special feeling of resistance.
Another feature of big inner-track systme is larger piece feet, highly improving anti-pop ability, eliminating 'hidden edges pop' occurring in routine 4x4 cubes.
Each corner and edge is combined with a unified big piece and an inner cap, making the friction surface smoother, reducing unnecessary bumps and lock-ups.
