Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If V2X communication is implemented with high device participation, then communication coverage and service capability are improved, but resource congestion occurs and energy consumption increases
Solution Approach 1:
The patent implements dynamic resource allocation where user equipment adjusts detection and sending parameters based on real-time user attribute information including geographic location, motion track, velocity, and resource load. This dynamic adaptation allows the system to maintain communication coverage while avoiding resource congestion by continuously optimizing resource usage according to current conditions
Solution Approach 2:
The patent changes key parameters such as detection frequency and sending frequency based on user attributes and resource load conditions. By dynamically adjusting these parameters, the system can adapt to varying communication demands and resource availability, preventing congestion while maintaining service capability
2Reliability
If detection frequency is increased to improve communication reliability, then reliability is improved, but energy consumption increases
Solution Approach 1:
The patent dynamically adjusts detection frequency based on user attribute information such as geographic location, motion track, and velocity. When users are stationary or in low-risk areas, detection frequency is reduced to save energy. When users are moving quickly or in high-risk areas, detection frequency is increased to maintain reliability
Solution Approach 2:
The system implements dynamic parameter adjustment where detection frequency is not fixed but adapts continuously based on real-time user attributes and communication conditions. This allows the system to maintain necessary reliability while minimizing energy consumption by only increasing detection frequency when actually needed
3Reliability
If sending frequency is increased to ensure information delivery, then communication reliability is improved, but resource congestion and energy consumption worsen
Solution Approach 1:
The patent dynamically adjusts sending frequency based on user attribute information including geographic location, motion track, and resource load. The system increases sending frequency when reliability is critical (e.g., high-speed movement, dangerous locations) and reduces it when conditions are stable, thereby ensuring information delivery while preventing resource congestion
Solution Approach 2:
The system uses feedback from resource load information and communication success rates to dynamically adjust sending frequency. When resource congestion is detected or communication failures occur, the system adapts by adjusting sending parameters to maintain reliability while managing resource usage
