Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If three-phase windings are wound around six pole posts of a conventional motor stator, then the motor can achieve three-phase operation, but the wire winding process becomes complex and maintenance becomes difficult
Solution Approach 1:
The stator is divided into multiple independent stator modules, each with its own pole posts and windings. This segmentation allows each module to be wound and assembled separately, significantly simplifying the wire winding process and making maintenance easier by allowing replacement of individual modules rather than the entire stator.
2Reliability
If wires are broken or have poor contact in a conventional motor, then the motor becomes unable to operate, but replacement of windings causes difficulty and increases costs
Solution Approach 1:
By dividing the stator into modular units with independent windings, the system maintains reliability through modular redundancy. When wiring issues occur, only the affected stator module needs to be replaced rather than the entire winding system, dramatically improving ease of repair and reducing maintenance costs.
Solution Approach 2:
The invention changes the structural parameter of the stator from a unified whole to separable modules. This parameter change enables independent replacement of stator modules, transforming the repair process from complex winding replacement to simple module substitution.
3Ease of repair
If multiple stator modules are used to simplify maintenance, then separate winding and replacement becomes possible, but the device structure becomes more complex
Solution Approach 1:
The stator is segmented into identical or similar modular units that can be independently manufactured and assembled. While this creates modular complexity, each module itself remains structurally simple and standardized, allowing for easier manufacturing and replacement despite the increased system modularity.
