Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a high-voltage interface is added to establish electrical connection between stator and high-voltage electronic system, then electrical connection reliability is improved, but device complexity increases
Solution Approach 1:
The patent combines the high-voltage interface with the centering element into a single integrated component. The centering element serves dual purposes: mechanically centering the stator on the cooling sleeve and providing the high-voltage electrical connection interface. This merging eliminates the need for separate centering and electrical connection components, thereby improving reliability while controlling complexity.
Solution Approach 2:
The centering element is designed with multi-functionality, simultaneously performing mechanical centering and electrical connection functions. The annular body of the centering element provides both the geometric interface for centering the stator and the electrical interface for high-voltage connections, reducing the overall number of components needed in the system.
2Manufacturing precision
If a centering element is introduced to fully center the stator on the cooling sleeve, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The centering element is merged with the high-voltage interface into a single integrated component. The annular body geometry provides the centering function while the same structure serves as the electrical interface, eliminating the need for separate centering mechanisms and reducing overall device complexity.
Solution Approach 2:
The centering element acts as an intermediary component between the cooling sleeve and the stator. It provides a standardized interface that simplifies the centering process during assembly and ensures precise positioning of the stator on the cooling sleeve without requiring complex alignment procedures.
3Temperature
If cooling fluid system is implemented through the cooling sleeve, then thermal management is improved, but device complexity increases
Solution Approach 1:
The cooling sleeve is designed with multi-functionality, serving both as a structural support component and as the cooling fluid conduit. The hollow interior of the cooling sleeve allows cooling fluid to flow through, providing thermal management without requiring separate cooling channels or additional cooling-specific components.
