Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a conventional smart magic cube uses a simple center shaft structure, then the assembly is simple, but the intelligence and ability to process real-time rotation information is low
Solution Approach 1:
The patent combines the sensor, rotor, stator, and main control module into an integrated center shaft assembly. The sensor is mounted on the core with the rotor connected to cube layers, allowing the center shaft to simultaneously perform mechanical support and intelligent detection functions, thereby improving automation without proportionally increasing complexity
Solution Approach 2:
The center shaft is designed to serve multiple functions: it provides mechanical support for cube layers, detects rotation through the sensor-rotor-stator mechanism, processes signals via the main control module, and transmits status information. This multi-functionality enhances intelligence while keeping the structure relatively compact
2Reliability
If the sensor is exposed outside the housing, then it can easily detect rotation, but it is vulnerable to impact and interference from cube blocks
Solution Approach 1:
The sensor is nested within the housing structure, specifically mounted on the core inside the housing cavity. The rotor extends outward to engage cube layers while the sensitive sensor components remain protected inside, similar to a nested doll structure where the sensing function is exposed but the sensor itself is protected
Solution Approach 2:
The rotor acts as an intermediary between the external cube layers and the internal sensor. It transmits rotation motion from the cube layers to the sensor without exposing the sensor itself to external impacts and interference, thereby maintaining both protection and measurement precision
3Ease of manufacture
If the stator and central block are assembled separately with complex connections, then adjustment is flexible, but assembly relationship becomes complicated
Solution Approach 1:
The sensor is directly mounted on the core, forming an integrated assembly. The stator is fixed to the housing which is part of the core structure, eliminating the need for separate connecting blocks and intermediate assemblies. This merging simplifies the assembly relationship while maintaining ease of manufacture

Function Achieved in This Case
The smart center shaft significantly increases the intelligence of the smart magic cube, allowing for accurate real-time status monitoring and enabling online competitions by simplifying assembly and improving compatibility with cube blocks.
Implementation Method 1
The sensor includes a stator and a rotor. The stator is fixed to the housing. The rotor is configured to be able to be connected to and synchronously rotated with a cube layer of the smart magic cube, so that the rotor is capable of being rotated relative to the stator following the cube layer

AI summary
A smart center shaft, a smart Rubik's Cube, and a timing method therefor. The smart center shaft comprises a core, a sensor, and a master control module. The core comprises a housing having a cavity. The sensor is mounted on the core. The sensor comprises a stator and a rotor. The stator is fixed on the housing. The rotor is configured to be connected and rotate simultaneously with a Rubik's Cube layer of the smart Rubik's Cube, thus allowing the rotor to rotate with the Rubik's Cube layer relative to the stator. The master control module is mounted within the cavity. The master control module is electrically connected to the sensor. The master control module acquires a rotation signal of the Rubik's Cube layer on the basis of the relative rotation between the rotor and the stator. The sensor and the core form one integral body, the degree of integration is high, and the consideration of complex assembly relations between the stator and a center block or an intermediate connecting block is avoided.
