Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual connection through bridging line is used, then electrical connection between vehicle bodies is achieved, but connection time and labor effort increase significantly
Solution Approach 1:
The patent combines multiple connecting functions (mechanical coupling, electrical connection, pneumatic connection, and grounding) into a single integrated device. The electrical connecting portion is merged with the mechanical connecting portion, allowing simultaneous mechanical and electrical connection when vehicles couple, eliminating the need for separate bridging line operations and reducing connection time while maintaining reliable electrical connectivity.
Solution Approach 2:
The connecting device performs multiple functions simultaneously: mechanical coupling through the mechanical connecting portion, electrical power and signal transmission through multiple voltage-level connecting ports, pneumatic connection through the pneumatic connecting portion, and grounding through the ground connecting portion. This multi-functional integration eliminates the need for separate bridging lines and manual connection steps.
2Reliability
If manual bridging line connection is used, then electrical connection is established, but operational complexity and labor intensity increase
Solution Approach 1:
The patent merges the electrical connecting portion directly with the mechanical connecting portion, so that electrical connections are automatically established when vehicles couple mechanically. This integration eliminates complex manual bridging line operations while ensuring stable electrical connections through direct port-to-port contact between vehicles.
3Reliability
If multiple separate connection methods are used, then comprehensive electrical connection is achieved, but device integration and automation capability decrease
Solution Approach 1:
The patent integrates high-voltage connecting ports, medium-voltage connecting ports, low-voltage connecting ports, ground connecting ports, pneumatic connecting portions, and mechanical connecting portions into a single unified device. This comprehensive integration achieves reliable multi-voltage electrical connection while simplifying the overall system structure and enabling automatic connection during vehicle coupling.
Solution Approach 2:
The connecting device provides universal functionality across multiple voltage levels (high-voltage for traction motors, medium-voltage for auxiliary systems, low-voltage for control systems) and includes mechanical, pneumatic, and grounding functions, all within a single integrated structure that automates the connection process.
