Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional wire routing without deflection aids is used, then the connecting wire can be simply routed, but the mechanical stability of the stator coil winding and connecting wire is insufficient
Solution Approach 1:
The patent introduces a deflection aid as an intermediary component between the contact wire and the stator coil winding. This deflection aid guides and secures the contact wire in a defined manner, providing mechanical stability without requiring complex routing structures. The deflection aid acts as a mediator that simplifies the overall wire routing system while ensuring reliable positioning.
2Reliability
If additional fixing measures are implemented for the contact wire, then the mechanical stability improves, but the device complexity and spatial requirements increase
Solution Approach 1:
The patent combines the deflection aid function with the existing end plate structure of the stator. By integrating the deflection aid into the end plate or positioning it within the existing motor housing structure, the solution avoids adding separate fixing components. This merging approach provides the necessary mechanical stability while minimizing additional device complexity and spatial requirements.
3Ease of operation
If the contact wire is routed with sufficient length for flexibility, then ease of installation is improved, but electrical losses increase due to longer wire length
Solution Approach 1:
The patent optimizes the contact wire length parameter by using the deflection aid to precisely position the wire. This allows the wire to be routed efficiently with minimal length required, reducing electrical losses. The deflection aid ensures that even with reduced wire length, the installation remains feasible by providing clear guidance on the wire path.
4Loss of energy
If the contact wire is tightly secured to minimize length, then electrical losses are reduced, but the mechanical stability and stress resistance decrease
Solution Approach 1:
The patent implements preliminary action by pre-positioning the deflection aid in the correct location before routing the contact wire. This pre-positioned deflection aid then guides the wire through its entire length, ensuring that the wire is securely supported along its path. This preliminary positioning action allows the wire to be tightly secured with minimal length while maintaining mechanical stability and stress resistance throughout the routing path.
