Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the brightness of the display is reduced to lower energy consumption, then energy consumption decreases, but image quality and visibility deteriorate
Solution Approach 1:
The patent applies local quality by adjusting the intensity of individual image points based on their color characteristics. Image points with colors similar to ambient light are displayed at lower intensity or not at all, while other points maintain normal intensity. This allows the display to reduce overall energy consumption while preserving visibility of important image content.
Solution Approach 2:
The patent changes the display parameter (intensity) dynamically based on the color and intensity of ambient light detected by sensors. The system continuously monitors ambient conditions and adjusts image point intensities accordingly, optimizing the balance between energy consumption and image quality in real-time.
2Adaptability or versatility
If manual brightness adjustment is used, then device complexity remains low, but adaptability to different lighting conditions is poor
Solution Approach 1:
The patent implements self-service by enabling the display system to automatically detect ambient light conditions and adjust image point intensities without user intervention. The ambient light sensors and processing system work autonomously to optimize display performance, eliminating the need for manual brightness controls while adapting to changing lighting environments.
Solution Approach 2:
The system uses feedback from ambient light sensors to continuously monitor lighting conditions and adjust display parameters accordingly. The sensor data feeds into the image processing system, which modifies image point intensities based on detected ambient light color and intensity, creating a closed-loop adaptive system.
