Engineering Contradiction Analysis
1Adaptability or versatility
If wired data interfaces according to ISO 11992 or SAE J1939 are used for vehicle connections, then interoperability between different vehicle manufacturers is improved, but the data throughput bandwidth is limited and insufficient for high-bandwidth applications
Solution Approach 1:
The patent replaces wired mechanical data interfaces (ISO 11992, SAE J1939) with wireless communication systems. The tractor and trailer units are equipped with wireless transceivers that establish radio frequency communication links, eliminating the need for physical data connectors while providing significantly higher data throughput capable of supporting real-time video streaming and large data transfers.
Solution Approach 2:
The wireless communication system serves multiple functions simultaneously: it provides high-bandwidth data transfer for video and sensor data, maintains interoperability between different manufacturers through standardized protocols, and enables communication regardless of the physical coupling state. The system can operate in both coupled and uncoupled configurations.
2Quantity of substance
If manual pairing of data connectors is required for high-bandwidth communication, then data throughput is improved, but the coupling procedure complexity and manual intervention requirements increase
Solution Approach 1:
The wireless communication system automatically establishes data transmission channels between tractor and trailer units without requiring manual connector pairing. The system performs self-configuration and automatic connection establishment through wireless protocol handshaking, eliminating the need for operators to manually connect data cables while maintaining high data throughput.
Solution Approach 2:
The patent replaces the mechanical process of manually connecting and pairing data connectors with an automated wireless communication system. Radio frequency transceivers automatically detect each other and establish communication links, replacing the entire mechanical connector pairing process with electronic wireless communication.
3Quantity of substance
If wireless communication is implemented for inter-vehicle data transfer, then data throughput and ease of coupling are improved, but reliability and data integrity may be compromised due to radio frequency interference and signal instability
Solution Approach 1:
The wireless communication system incorporates forward error correction codes and redundant data transmission protocols that protect against radio frequency interference and signal degradation. The system prepares for potential communication failures by implementing checksum verification, automatic retransmission mechanisms, and error detection algorithms that ensure data integrity even in challenging RF environments.
Solution Approach 2:
The system implements continuous feedback mechanisms where receiving units send acknowledgment signals to transmitting units, allowing for real-time detection of transmission errors. The communication protocol includes automatic error detection and correction cycles, where signal quality is continuously monitored and transmission parameters are dynamically adjusted to maintain reliable communication despite RF interference.
