Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If visible light image generation mode is used for invisible light output, then the image processing can be performed with standard color settings, but the output image appearance becomes unnaturally colored and different from the original object
Solution Approach 1:
The image processing system dynamically switches between color image generation mode and single-color image generation mode based on the selected light type (visible or invisible). This dynamic adaptation ensures that the appropriate processing mode is applied for each imaging condition, resolving the contradiction between processing simplicity and color accuracy.
Solution Approach 2:
The system changes the image generation parameter (color mode vs. single-color mode) according to the light type being used. When invisible light is selected, the system switches to single-color mode to maintain accurate representation of the original object's appearance, while visible light uses standard color mode.
2Adaptability or versatility
If manual switching between visible and invisible light settings is required, then the system can maintain flexibility, but the operation becomes complex and time-consuming
Solution Approach 1:
The system automatically determines and switches to the appropriate image generation mode based on the selected operating mode (visible or invisible light). This self-service mechanism eliminates the need for manual setting changes, allowing the system to adapt to different light types automatically while maintaining ease of operation.
Solution Approach 2:
The system uses feedback from the selected operating mode to automatically adjust the image generation settings. When the operating mode changes between visible and invisible light, the system receives this feedback and automatically switches the image processing mode accordingly, resolving the contradiction between versatility and ease of operation.
3Ease of operation
If automatic mode switching is implemented, then the ease of operation improves, but the device complexity increases
Solution Approach 1:
The image sensor is designed to be universally sensitive to both visible light and invisible light wavelengths, allowing a single device to perform multiple imaging functions. This multi-functionality reduces the need for separate specialized sensors and simplifies the overall system architecture while enabling automatic mode switching.
Solution Approach 2:
The system merges the visible light and invisible light imaging capabilities into a single integrated system with unified control. By combining these functions and using a common image sensor that responds to both wavelength ranges, the system achieves automatic mode switching without significantly increasing device complexity.
