Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If wireless communication is used to provide high-bandwidth data transmission, then data communication bandwidth is improved, but reliability and efficiency of the communication link deteriorate due to geometric variations and orientation changes
Solution Approach 1:
The patent applies beam adaptation that dynamically adjusts the communication beam direction based on real-time radio measurements and articulation angle feedback. This dynamic adjustment compensates for geometric variations and orientation changes between coupled vehicles, maintaining reliable high-bandwidth communication despite relative motion and positioning changes.
Solution Approach 2:
The system implements a feedback mechanism where radio measurements and articulation angle information are continuously monitored and used to adjust the beam direction. This closed-loop control ensures the communication link maintains optimal performance despite changes in vehicle geometry and orientation during coupling and operation.
2Adaptability or versatility
If manual intervention is required for data connector combination, then interoperability control is improved, but ease of operation and coupling speed deteriorate
Solution Approach 1:
The wireless communication system enables automatic connection establishment between vehicles without manual data connector combination. The system self-configures the communication link using radio measurements and articulation angle detection, eliminating the need for manual intervention while maintaining interoperability through standardized protocols.
Solution Approach 2:
The patent replaces manual mechanical connector combination with an automated wireless communication system. Instead of physically connecting data cables, the system establishes communication links through radio frequency transmission, eliminating manual operations while maintaining data exchange capabilities.
3Adaptability or versatility
If standardized wired interfaces are used for data communication, then interoperability is improved, but data transmission bandwidth deteriorates
Solution Approach 1:
The patent replaces wired mechanical data interfaces with wireless communication technology. This substitution enables high-bandwidth data transmission capable of supporting real-time video and sensor data exchange, while maintaining interoperability through standardized wireless communication protocols and beam adaptation mechanisms.
4Reliability
If beam adaptation is continuously performed to maintain link reliability, then communication reliability is improved, but energy consumption and radio-frequency emissions worsen
Solution Approach 1:
The system performs beam adaptation periodically based on detected changes in articulation angle or radio measurement variations rather than continuously. This periodic adjustment maintains communication reliability while reducing energy consumption and radio-frequency emissions during periods when the link is stable and no adjustment is needed.
