Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If statistical processing is executed on time information from multiple synchronization sources, then time synchronization is achieved, but frequency stability deteriorates due to oscillator degradation over time
Solution Approach 1:
The detector performs preliminary detection of oscillator variation information before the calculator processes time information. By detecting degradation trends in advance and notifying the calculator, the system can adjust the predetermined process proactively, preventing frequency stability deterioration from affecting synchronization accuracy.
Solution Approach 2:
A feedback loop is established where the detector continuously monitors oscillator variation information and feeds this data back to the calculator. The calculator then adjusts its predetermined process based on this feedback, dynamically compensating for oscillator degradation and maintaining both synchronization accuracy and frequency stability.
2Productivity
If oscillators are used in synchronization sources, then time information is generated, but frequency stability deteriorates as oscillators degrade over time
Solution Approach 1:
The synchronization source performs self-diagnosis through the detector, which automatically monitors its own oscillator's variation information. This self-service mechanism enables the system to detect and report its own degradation without external intervention, allowing for timely adjustments to maintain frequency stability while continuing time information generation.
Solution Approach 2:
The detector provides continuous feedback on oscillator health to the calculator, enabling dynamic adjustment of the time information processing. This feedback mechanism allows the system to maintain productivity by continuing operation while adapting the predetermined process to compensate for degradation, thereby preserving frequency stability.
3Stability of the object's composition
If the predetermined process is adjusted based on oscillator variation information, then frequency stability is maintained, but device complexity increases due to additional detectors and processing
Solution Approach 1:
The detector is designed with multi-functionality, serving both to detect oscillator variation information for frequency stability maintenance and to provide data for adjusting the predetermined process. This universal component performs multiple functions within a single device, reducing overall system complexity compared to having separate detection and adjustment mechanisms.
Solution Approach 2:
The detection function and the time information processing function are merged into an integrated system. The detector's output directly feeds into the calculator's predetermined process adjustment, eliminating the need for separate complex control systems and reducing overall device complexity while maintaining frequency stability.
