Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If an interconnector with intricate shape is used to connect winding ends, then the electrical connection functionality is achieved, but the installation complexity and positioning precision requirements increase
Solution Approach 1:
The patent applies asymmetry by designing the interconnector with a symmetrical geometry that allows it to be mounted in multiple positions (at least two different positions). This symmetrical design enables the interconnector to be universally compatible with different winding end configurations, simplifying installation by eliminating the need for precise orientation during mounting while maintaining effective electrical connection functionality.
2Ease of operation
If a symmetrical interconnector design is used, then the mounting process is simplified and multiple mounting positions are enabled, but the precision of electrical connection may be compromised
Solution Approach 1:
The interconnector is designed with universal mounting capability, allowing it to be installed in at least two different positions on the winding. This multi-functional design ensures that regardless of the mounting position chosen, the interconnector maintains effective electrical connection between winding ends, thereby simplifying operation without compromising connection precision.
3Productivity
If identical interconnector parts are used for different positions, then production costs are reduced and inventory is simplified, but the adaptability to different mounting configurations must be maintained
Solution Approach 1:
The symmetrical geometry of the interconnector enables identical parts to be used across different mounting positions. This design ensures that the same interconnector component can be universally applied regardless of which mounting position is selected, thereby reducing production complexity and inventory requirements while maintaining full adaptability to different mounting configurations.

AI summary
A stator for a rotary electric machine includes a stator body having an axis (X), and a winding including at least one overhang projecting axially from the stator body and winding ends extending axially beyond the overhang from the stator body. Also included is an interconnector mounted on the overhang of the winding, including an insulating body and at least one track having track ends. At least two winding ends are each assembled with one of the corresponding track ends, and the track ends are symmetrical relative to a plane containing the axis and relative to a plane transverse to the axis.
