Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate communication systems are used for different road services, then each service can be provided, but information sources become dispersed and system complexity increases
Solution Approach 1:
The patent merges multiple separate communication systems into a single integrated road telecommunications system. The infrastructure combines vehicular communication modules for autonomous driving, user mobile device communication for information access, and road service communication into one unified network managed by local and remote control centers, thereby reducing system complexity while maintaining comprehensive service coverage.
Solution Approach 2:
The road telecommunications system is designed with universal communication modules that can handle multiple functions simultaneously. The same infrastructure supports vehicular communication for autonomous driving, user device communication for information access, and road service communication, making the system multi-functional and adaptable to various applications.
2Productivity
If a centralized infrastructure is implemented to unify information access, then information channel efficiency improves, but system reliability requirements increase
Solution Approach 1:
The centralized infrastructure is segmented into distributed local control centers that can operate autonomously. Each local control center manages a specific geographic area and can function independently, ensuring that if one segment fails, others continue to operate. This segmentation maintains high information channel efficiency while distributing reliability requirements across multiple independent units.
Solution Approach 2:
The system incorporates redundant communication channels and backup mechanisms in advance. Multiple communication paths are established between local control centers and the remote control center, ensuring that if one channel fails, alternative channels are already available to maintain system reliability and continuous operation.
3Extent of automation
If communication modules are installed in every vehicle for autonomous driving, then driving automation capability improves, but cost and device complexity increase
Solution Approach 1:
The system uses road-side infrastructure as an intermediary to provide communication services. Instead of requiring every vehicle to have complex communication modules, the infrastructure provides the necessary communication capabilities through local control centers and access stations, reducing the complexity and cost of vehicle equipment while maintaining autonomous driving capability.
