Engineering Contradiction Analysis
1Speed
If a light detection device is used for X-ray detection, then X-ray energy can be detected with fast electronic imaging, but the device becomes abnormal after X-ray irradiation and requires a time interval between irradiations
Solution Approach 1:
The system performs a self-detection operation before regular X-ray detection to determine whether the light detection device is abnormal. By conducting this preliminary check, the system identifies potential device abnormalities before they affect actual X-ray imaging, preventing detection errors while maintaining fast electronic imaging capabilities.
Solution Approach 2:
The light detection device performs self-detection using its own light source module and sensing substrate. The device captures first image data without external light and second image data with the light source activated, then compares these images to determine its own operational status. This self-service mechanism enables the device to monitor its health without requiring external intervention.
2Measurement precision
If a time interval is required between X-ray irradiations due to device abnormality, then detection accuracy may be maintained, but operational convenience deteriorates and medical disputes may occur
Solution Approach 1:
The self-detection operation is performed before regular X-ray detection to determine device normalcy. This preliminary action ensures detection accuracy by identifying abnormalities beforehand, while eliminating the need for mandatory time intervals between irradiations, thereby improving operational convenience and preventing medical disputes.
Solution Approach 2:
The system compares first image data (without external light) and second image data (with light source activated) to generate feedback about device normalcy. This feedback mechanism allows the system to maintain detection accuracy by identifying abnormalities while enabling continuous operation without forced time intervals, thus improving ease of operation.
3Reliability
If self-detection is implemented by capturing image data with and without light source, then device normalcy can be determined, but additional time and operations are required
Solution Approach 1:
The self-detection operation merges the capture of first image data (without external light) and second image data (with light source) into a single integrated process. By combining these measurements and comparing them together, the system determines device normalcy efficiently without requiring separate detection procedures, thus minimizing additional time consumption.
Solution Approach 2:
The self-detection uses a simplified comparison between two image data sets rather than performing exhaustive diagnostic procedures. This partial action approach provides sufficient reliability for determining device normalcy without the time cost of more comprehensive testing, achieving an optimal balance between reliability and time efficiency.
