Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different display devices are used, then variety of display options is improved, but image rendering consistency deteriorates
Solution Approach 1:
The system changes the video data parameters dynamically based on the detected characteristics of the display device. The processor adjusts parameters such as brightness, contrast, and color balance by modifying the video signal to compensate for the specific response characteristics of different projectors, thereby achieving consistent image rendering across diverse display devices.
Solution Approach 2:
The system implements a feedback mechanism where a detecting element measures the actual image output from the display device, and this measurement is fed back to the processor. The processor then adjusts the video data accordingly to correct deviations from the desired image rendering, ensuring consistency across different display devices.
2Adaptability or versatility
If ambient light level is increased, then tolerance to environmental conditions is improved, but image quality deteriorates
Solution Approach 1:
The system dynamically adjusts video data parameters in response to detected ambient light conditions. When higher ambient light is detected, the processor increases parameters such as brightness and contrast in the video signal to maintain image quality, allowing the system to tolerate a wider range of environmental lighting conditions.
Solution Approach 2:
The detecting element continuously monitors ambient light conditions and provides feedback to the processor. Based on this feedback, the processor real-time adjusts the video data to compensate for the effects of varying ambient light, thereby maintaining image quality across different environmental conditions.
3Adaptability or versatility
If projector brightness is increased, then tolerance to ambient light is improved, but color accuracy deteriorates
Solution Approach 1:
The system adjusts multiple video data parameters simultaneously, including brightness, contrast, and color balance. When projector brightness is increased to tolerate ambient light, the processor compensates by adjusting color balance and other parameters to maintain color accuracy, preventing the degradation that would normally occur with higher brightness settings.
Solution Approach 2:
The detecting element measures the actual colorimetric characteristics of the projected image and provides feedback to the processor. The processor uses this feedback to make real-time adjustments to color balance and other parameters, ensuring that color accuracy is maintained even when projector brightness is increased for ambient light tolerance.
