Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the display device luminance is adjusted to compensate for poor lighting, then image capture quality improves, but energy consumption increases
Solution Approach 1:
The system dynamically changes the luminance parameter of the display device based on detected ambient illumination levels. When poor lighting is detected, the display luminance is increased to provide additional illumination for the image capture device, thereby improving image quality without continuously operating at high energy consumption levels.
Solution Approach 2:
The system uses ambient light sensors to detect illumination conditions and provides feedback to the processor, which then adjusts the display luminance accordingly. This closed-loop feedback mechanism ensures the display only consumes additional energy when actually needed to improve image capture quality, optimizing the trade-off between image quality and energy consumption.
2Adaptability or versatility
If ambient light sensors and illumination adjustment are added, then adaptability to lighting environments improves, but device complexity increases
Solution Approach 1:
The display device serves multiple functions: it displays visual information to the user and simultaneously acts as an illumination source for the image capture device in low-light conditions. This multi-functionality reduces the need for separate dedicated components, thereby limiting the increase in device complexity while improving adaptability to various lighting environments.
Solution Approach 2:
The patent combines the illumination function with the existing display device rather than adding a completely separate illumination system. By merging the illumination capability into the display device itself, the system achieves better adaptability to lighting environments while minimizing the increase in overall device complexity.
