Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If atomic clocks or dedicated synchronization cables are used for RF device synchronization, then timing accuracy is improved, but device complexity and system cost increase
Solution Approach 1:
The patent introduces a network clock and timing protocol as an intermediary mechanism to synchronize RF devices. Instead of using complex atomic clocks at each device or dedicated synchronization cables, the system uses a centralized network clock that distributes time information through standard network infrastructure, thereby reducing device complexity while maintaining synchronization accuracy
Solution Approach 2:
The patent replaces physical/mechanical synchronization methods (atomic clocks, dedicated cables) with electronic/software-based timing protocols transmitted over network infrastructure. This substitution uses digital timing messages and protocol-based synchronization instead of physical time reference devices, reducing hardware complexity
2Measurement precision
If dedicated synchronization cables are used, then timing accuracy is improved, but ease of operation and network flexibility deteriorate
Solution Approach 1:
The patent makes the network infrastructure universal by using standard network cables and protocols for both data communication and time synchronization. The same network infrastructure serves multiple functions: carrying RF device data traffic and distributing time synchronization information, thereby improving ease of operation and network flexibility while maintaining synchronization accuracy
Solution Approach 2:
The patent merges data communication and time synchronization functions into a single network infrastructure. Instead of having separate dedicated synchronization cables and data network cables, the system combines both functions over the same network medium, simplifying network operation and increasing flexibility
