Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the working distance of the tracking camera is very short, then the detection range is small, but the target can easily be moved out of the detection range
Solution Approach 1:
The patent applies the dynamics principle by making the detection range of the tracking camera adjustable rather than fixed. The system dynamically adapts the detection range based on the working distance between the microscope and the target object. This allows the tracking camera to maintain optimal detection precision at short working distances while expanding its detection range when the working distance increases, thereby resolving the contradiction between measurement precision and adaptability.
2Adaptability or versatility
If the working distance of the tracking camera is very large, then the detection range is large, but the resolution of the imaged target is too low
Solution Approach 1:
The system dynamically adjusts the detection range of the tracking camera based on the working distance. When the working distance is large, the detection range is expanded to maintain adaptability, while when the working distance is short, the detection range is reduced to maintain high resolution. This dynamic adaptation resolves the contradiction between detection range and resolution by optimizing the detection parameters according to the actual working conditions.
3Adaptability or versatility
If the working distance is long, then the detection range is sufficient, but the image is underexposed
Solution Approach 1:
The patent implements feedback control by continuously monitoring the exposure status of the image and adjusting the illumination intensity accordingly. When the working distance is long and the image becomes underexposed, the system increases the illumination intensity to compensate for the light loss. This feedback mechanism ensures that the image quality remains optimal regardless of the working distance, resolving the contradiction between detection range and image exposure.
4Measurement precision
If the working distance is short, then the resolution is high, but the image is overexposed
Solution Approach 1:
The system uses feedback control to monitor image exposure and dynamically adjust illumination intensity. When the working distance is short and the image becomes overexposed, the system reduces the illumination intensity to prevent overexposure while maintaining high resolution. This feedback mechanism resolves the contradiction between resolution and image exposure by optimizing illumination based on real-time detection of working distance and image quality.
