Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing time accuracy methods (optical clocks, TAI, UTC) are used, then time synchronization is maintained, but measurement precision is limited and frequent coordination adjustments are required
Solution Approach 1:
The patent replaces traditional mechanical and atomic timekeeping systems with an optical-based measurement system using laser interferometry. This substitution enables hyper-precise time interval measurements (sub-nanosecond accuracy) without requiring frequent coordination adjustments, as the optical method directly measures time intervals through light propagation rather than relying on mechanical oscillators or atomic transitions that drift over time.
Solution Approach 2:
The patent introduces optical signals and laser interferometry as intermediary mechanisms to measure time intervals. By using light as a mediator between timing events, the system achieves high precision measurements without direct mechanical or electronic counting, thereby reducing the need for coordination adjustments and improving overall measurement accuracy.
