Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicles use multiple synchronization sources in complex environments, then synchronization coverage is improved, but mutual interference increases and spectral efficiency deteriorates
Solution Approach 1:
The patent changes the parameter of synchronization source selection by introducing priority levels and selection criteria. Different synchronization sources (GNSS, base station, other vehicles) are assigned different priorities and selection parameters, allowing the system to dynamically select the most appropriate source based on current environmental conditions, thereby improving synchronization coverage while avoiding interference from multiple simultaneous sources
Solution Approach 2:
Each vehicle equipped with synchronization capabilities acts as a potential synchronization source for other vehicles. The system enables self-organizing synchronization where vehicles autonomously select synchronization sources based on predefined criteria and priority information, eliminating the need for centralized coordination while improving overall network synchronization coverage
2Device complexity
If vehicles autonomously select synchronization sources without coordination, then system complexity is reduced, but synchronization accuracy and interference management deteriorate
Solution Approach 1:
The patent applies preliminary action by pre-configuring priority information and selection criteria for different synchronization sources before actual synchronization occurs. Each vehicle is pre-programmed with rules for selecting synchronization sources based on signal quality, source type priorities, and environmental conditions, enabling autonomous decision-making while maintaining synchronization accuracy without real-time coordination complexity
Solution Approach 2:
The system applies local quality by allowing each vehicle to independently evaluate and select synchronization sources based on local signal conditions and pre-defined priority rules. Different vehicles may select different synchronization sources based on their local environment, with each selection optimized for local conditions while following统一的 priority principles, thus achieving both autonomy and accuracy
