Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If color temperature information is transmitted from the control device to the image processing device, then color rendering accuracy is improved, but data transmission requirements increase
Solution Approach 1:
The patent extracts only the essential color temperature information from the control device and transmits it to the image processing device, rather than transmitting complete calibration datasets. This selective extraction maintains color rendering accuracy while minimizing data transmission volume.
Solution Approach 2:
The image processing device receives color temperature information and uses it to generate white balance correction parameters locally, creating a simplified copy of the color correction data needed for accurate rendering without transmitting the entire correction dataset.
2Measurement precision
If white balance adjustment is performed based on color temperature information, then tissue discriminability is improved, but system complexity increases
Solution Approach 1:
The image processing device automatically performs white balance adjustment using the received color temperature information without requiring manual intervention or complex external calibration systems. The system self-regulates to maintain optimal tissue discriminability.
Solution Approach 2:
The system establishes a feedback loop where the control device transmits color temperature information to the image processing device, which then adjusts white balance parameters accordingly. This automated feedback mechanism improves tissue discriminability while keeping system complexity manageable through standardized communication protocols.
3Adaptability or versatility
If multiple color temperature settings are supported, then adaptability is improved, but calibration data requirements increase
Solution Approach 1:
The patent supports multiple color temperature settings by transmitting varying parameter values (color temperature information) from the control device to the image processing device. Each parameter change corresponds to a different illuminant setting, enabling adaptability without requiring separate complete calibration datasets for each temperature.
Solution Approach 2:
The communication interface between the control device and image processing device is designed to handle multiple color temperature settings through a universal data transmission protocol. This multi-functional approach allows the system to adapt to different surgical lighting conditions while using a single calibration framework.
