Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional electrical supply systems are used for stator coil windings, then electrical connection is achieved, but the system becomes complex and unstable
Solution Approach 1:
The patent combines multiple electrical connection functions into a single integrated contact ring structure that simultaneously connects multiple lines to multiple coil windings. This merging of previously separate connection elements into one component reduces overall system complexity while maintaining reliable electrical supply to all coil windings.
Solution Approach 2:
The contact ring serves multiple functions simultaneously: it provides electrical connection to multiple lines, distributes current to multiple coil windings, and maintains structural organization of the electrical supply system. This multi-functionality eliminates the need for separate dedicated connection components for each line-coil pairing, thereby simplifying the system.
2Volume of moving object
If traditional electrical supply systems are used for stator coil windings, then electrical connection is achieved, but the system size increases
Solution Approach 1:
The contact ring structure allows lines and coil windings to be arranged in a nested or radially organized configuration, where multiple electrical connections are packed into a compact circular arrangement. This nesting approach enables dense packing of electrical components without increasing the overall stator volume significantly.
Solution Approach 2:
The patent transitions from a linear or planar arrangement of electrical connections to a three-dimensional radial configuration centered on the contact ring. By organizing connections in multiple spatial dimensions around the rotational axis, the system achieves compactness without sacrificing connection reliability or increasing complexity.
3Reliability
If lines are separately manufactured and connected to coil windings, then manufacturing flexibility is achieved, but connection reliability decreases
Solution Approach 1:
The contact ring is designed and prepared in advance with predetermined connection points and routing paths for the lines. This preliminary preparation ensures that when lines are connected to the contact ring and subsequently to coil windings, the connections are reliable and consistent. The pre-structured contact ring guides the assembly process, maintaining connection quality.
Solution Approach 2:
The contact ring acts as an intermediary component between the separately manufactured lines and coil windings. It provides a standardized, reliable connection interface that ensures consistent electrical contact regardless of how the lines and coils are manufactured. This intermediary structure guarantees connection reliability while still allowing manufacturing flexibility for the individual components.
