Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If static or semi-static resource allocations are used, then network construction costs are reduced and system complexity is lowered, but resource allocation optimization for individual vehicles cannot be achieved
Solution Approach 1:
The patent implements dynamic network slice selection by enabling vehicles to switch between different network slice instances based on real-time driving modes and states. The network slice selection function dynamically determines appropriate slices for autonomous driving, remote driving, and parking modes, transforming the static network configuration into an adaptive system that optimizes resources according to actual vehicle conditions without requiring complex manual configuration.
2Reliability
If multiple physical networks are built for different services, then service performance requirements are met, but network construction costs increase
Solution Approach 1:
The patent applies network slicing technology to divide a single physical network into multiple virtual network slices, each optimized for specific services such as autonomous driving communication, remote driving communication, and general vehicle services. This segmentation allows different service performance requirements to be met through logical network divisions rather than building separate physical networks, reducing infrastructure resource consumption while maintaining service quality.
Solution Approach 2:
The patent creates a universal physical network infrastructure that can serve multiple different services simultaneously through network slicing. The same physical network resources are shared across different vehicle communication needs by dynamically allocating appropriate network slice instances, making the network infrastructure multi-functional and eliminating the need for dedicated physical networks for each service type.
3Productivity
If network slice instances are dynamically selected based on driving mode and state, then communication performance is optimized, but device complexity and control complexity increase
Solution Approach 1:
The patent implements self-service functionality in the vehicle's communication module, which automatically determines the current driving mode and state, then autonomously selects and switches to the appropriate network slice instance without requiring manual intervention or complex external control systems. The communication module monitors vehicle conditions and independently manages network slice selection, simplifying the overall system architecture while maintaining optimized communication performance.
Solution Approach 2:
The patent establishes a feedback mechanism where the communication module continuously monitors vehicle driving modes and states, and based on this feedback information, dynamically adjusts network slice selection. The system uses feedback from vehicle condition changes to trigger appropriate network slice switches, ensuring communication performance is optimized according to actual operational needs while maintaining manageable system complexity through rule-based decision logic.
