Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired connections are used for data communication between vehicles, then connection reliability is improved, but performance degradation occurs during connection/disconnection cycles
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless communication system using electromagnetic fields. The wireless communication modules transmit data without physical contact, eliminating wear and performance degradation associated with repeated connection and disconnection cycles of wired systems.
2Stability of the object's composition
If wired connections are used for data communication between vehicles, then data transfer stability is improved, but vulnerability to electromagnetic interference increases
Solution Approach 1:
The patent substitutes electromagnetic wireless communication for wired electrical connections. By using radio frequency electromagnetic waves instead of electrical signals through cables, the system achieves immunity to electromagnetic interference that plagues wired systems, while maintaining stable data transfer through protocol-level error correction and retransmission mechanisms.
3Speed
If wireless communication modules are placed in close proximity, then communication speed is improved, but electromagnetic interference between modules increases
Solution Approach 1:
The patent extracts and separates the transmit and receive functions into distinct wireless communication modules positioned at opposite ends of the connector assembly. This spatial separation, combined with directional antenna design and frequency division multiplexing, allows close proximity placement for high-speed communication while minimizing electromagnetic interference between transmitting and receiving modules.
4Ease of operation
If wireless communication is implemented between vehicles, then ease of connection is improved, but device complexity increases
Solution Approach 1:
The patent merges the wireless communication modules directly into the existing connector assembly housing, combining multiple functions (mechanical connection, electrical connection, and wireless communication) into a single integrated unit. This integration simplifies the overall system by eliminating separate wireless communication components and reducing the number of discrete parts that need to be managed.
