Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single radio access technology is used for vehicle communication, then the system is simple to manage, but it cannot meet diverse requirements in terms of delay, reliability, and throughput under various circumstances
Solution Approach 1:
The patent implements multi-RAT (Radio Access Technology) capability where user equipment is designed to support multiple RATs (e.g., LTE, 5G NR, Wi-Fi, DSRC) simultaneously. This allows a single communication system to fulfill diverse requirements for delay, reliability, and throughput by selecting appropriate RATs based on traffic conditions and service needs, thereby achieving universality without being constrained by a single technology's limitations.
Solution Approach 2:
The system dynamically selects and switches between different RATs based on real-time communication conditions and service requirements. The patent introduces dynamic RAT selection mechanisms that adapt the communication technology choice to current network conditions, enabling the system to optimize performance for each specific circumstance while maintaining overall system flexibility and responsiveness.
2Reliability
If multiple radio access technologies are used to meet diverse communication requirements, then adaptability and service quality improve, but the complexity of determining and managing communication groups increases
Solution Approach 1:
The patent segments the communication group determination process into distinct phases and criteria. It separates the identification of suitable UEs based on different RATs from the actual group formation and communication establishment. This segmentation allows the system to handle multi-RAT complexity by processing it in manageable steps: first identifying candidate UEs, then selecting appropriate RATs, and finally establishing communication groups, thereby reducing overall decision-making complexity.
Solution Approach 2:
The system introduces an intermediary mechanism that facilitates multi-RAT group determination. This intermediary layer processes and coordinates the interactions between UEs with different RAT capabilities, managing the complexity of compatibility checking and group formation. The intermediary simplifies the overall process by centralizing the coordination functions and providing standardized interfaces for RAT selection and group management.
3Productivity
If traditional communication technologies are used, then the system is easy to operate, but traffic efficiency and fuel consumption are not optimized
Solution Approach 1:
The patent implements self-service mechanisms where the communication system automatically determines optimal RAT selections and group formations without requiring manual intervention. The system autonomously monitors traffic conditions, selects appropriate communication technologies, and manages group communications to optimize traffic efficiency. This self-service approach maintains ease of operation while significantly improving productivity, as the system handles complex optimizations automatically rather than requiring user involvement.
