Engineering Contradiction Analysis
1Measurement precision
If manual on-site detection is used, then measurement precision can be achieved, but productivity is low and loss of time is high
Solution Approach 1:
The patent replaces manual mechanical detection operations with an automated electronic detection system. The system uses signal transmission between transmitting and receiving devices, automatic time synchronization protocols (IEEE1588), and electronic data processing to eliminate manual intervention. The oscilloscope automatically captures and processes signals, calculating time differences through programmed algorithms rather than human operators performing manual measurements.
Solution Approach 2:
The detection system performs self-service through automatic time synchronization and self-calibration mechanisms. The transmitting and receiving devices automatically synchronize their clocks using IEEE1588 protocol, and the system automatically captures signals, processes data, and calculates time differences without requiring external manual intervention. The system serves itself by maintaining and verifying its own timing accuracy through built-in reference signals and automatic correction algorithms.
2Measurement precision
If non-automatic traceability detecting is used, then measurement precision can be achieved, but loss of time is high and productivity is low
Solution Approach 1:
The system performs preliminary actions by pre-synchronizing the clocks of transmitting and receiving devices using IEEE1588 time synchronization protocol before actual time difference detection. This preliminary synchronization establishes a known reference relationship between devices, allowing rapid subsequent measurements without requiring manual data collection and retroactive calculation. The system prepares detection parameters, signal paths, and synchronization states in advance to enable immediate accurate measurement.
Solution Approach 2:
The patent replaces the manual process of collecting digital time data and retroactively calculating time differences with an automated real-time detection system. The oscilloscope automatically captures timing signals, the system processes data through programmed algorithms, and immediately outputs time difference results. This electronic automated system eliminates the time-consuming manual data collection, storage, and calculation processes while maintaining measurement precision.
3Productivity
If automated detection system is implemented, then productivity is improved, but device complexity increases
Solution Approach 1:
The detection system achieves multi-functionality by integrating multiple capabilities into a unified platform. The same system performs time synchronization, signal transmission, signal capture, data processing, and time difference calculation. The transmitting device, receiving device, and oscilloscope work together as an integrated automated system that can detect time differences across different phases and conditions without requiring separate specialized equipment for each function, thereby managing complexity while maintaining high productivity.
Solution Approach 2:
The system uses standardized communication protocols (IEEE1588) and intermediate processing components (oscilloscope as signal intermediary) to manage complexity. The protocol acts as an intermediary layer that standardizes time synchronization between devices, while the oscilloscope serves as an intermediate device that captures signals from multiple sources and presents processed data to the analysis system. These intermediaries simplify the overall system architecture by providing standardized interfaces and abstraction layers.
