Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single network (4/5G public network, Wi-Fi, or 4/5G private network) is used for remote control communication, then the system structure is simple, but the network coverage has blind spots and cannot fully satisfy remote control requirements in all areas
Solution Approach 1:
The patent combines multiple heterogeneous networks (4G public network, 5G public network, Wi-Fi, and 4G/5G private networks) into a unified remote control communication system. The vehicle terminal can simultaneously access multiple networks and select the most appropriate one based on network quality, ensuring reliable remote control coverage across all areas without requiring a completely new complex infrastructure.
2Reliability
If multiple heterogeneous networks are used to ensure coverage, then the remote control reliability is improved, but the message management and network selection complexity increases
Solution Approach 1:
The vehicle terminal autonomously performs network selection and message management without requiring complex external coordination. The terminal evaluates network quality indicators (signal strength, latency, packet loss) and automatically selects the most suitable network for remote control communication. The system also self-manages message routing and filtering across different networks, reducing the need for complex external message management infrastructure.
3Speed
If network quality is not optimized, then the system operation is simple, but the remote control response time is delayed and control accuracy is reduced
Solution Approach 1:
The system dynamically adjusts network selection based on real-time network quality conditions. The vehicle terminal continuously monitors network parameters (signal strength, latency, bandwidth) and switches between different networks to maintain optimal remote control response speed. This dynamic adaptation ensures high-speed remote control operation without requiring a fixed complex network optimization system.
