Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a conventional galvanometer motor uses a motor housing made of iron with a laminate of silicon steel sheets as a coil frame, then the motor provides sufficient structural strength and magnetic properties, but the device complexity increases and assembling complexity increases
Solution Approach 1:
The patent merges the motor housing and coil frame into a single integrated housing structure. The housing includes a stator assembly with a coil winding groove directly formed in the housing body, eliminating the need for a separate silicon steel sheet laminate coil frame. This integration reduces the number of parts while maintaining both structural strength and magnetic properties through the housing's own design.
2Stability of the object's composition
If the core is fixed to the housing using an epoxy resin, then the structural stability is improved, but the assembling efficiency decreases and ease of repair worsens
Solution Approach 1:
The patent extracts the core assembly (stator assembly with coil) as a separate, removable unit from the housing. The stator assembly can be independently assembled and then installed into the housing without requiring epoxy resin bonding. This extraction allows for tool-free assembly and disassembly, improving assembling efficiency while maintaining structural stability through precise mechanical fitments and positioning structures.
3Volume of moving object
If the motor apparatus is compact in terms of space, then the volume is reduced, but the adaptability decreases
Solution Approach 1:
The patent implements a dynamic and reconfigurable coil winding structure within the integrated housing. The coil winding groove is designed to accommodate different winding configurations and parameters. The stator assembly can be reconfigured with different coil windings to provide various winding parameters, allowing a single compact motor design to adapt to different application requirements without changing the overall motor volume.
4Stability of the object's composition
If conventional galvanometer motors include multiple separate components such as front bearing mounting seat, rear bearing mounting seat, and coil frame, then the structural integrity is maintained, but the assembling complexity increases and ease of repair worsens
Solution Approach 1:
The patent segments the motor into two main functional modules: the integrated housing (containing the stator assembly with coil winding groove) and the rotor assembly (with magnet and bearing). This segmentation allows each module to be independently assembled, tested, and replaced. The bearing mounting seats are integrated into the housing structure, eliminating separate bearing housing components. This modular segmentation maintains structural integrity while dramatically simplifying assembly and repair operations.
