Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If screen brightness is reduced in dark environments, then power consumption decreases, but color identification capability deteriorates
Solution Approach 1:
The patent applies parameter changes by adjusting color saturation and temperature parameters based on ambient light conditions. When brightness is low, the system increases color saturation and adjusts color temperature to compensate for reduced human eye sensitivity, thereby maintaining color identification capability while keeping screen brightness low to save power.
Solution Approach 2:
The system performs preliminary color compensation adjustments before displaying content in dark environments. By detecting ambient light levels in advance and pre-adjusting color parameters, the system ensures that color information remains perceivable even before the user actually views the display, preventing the loss of color identification capability.
2Loss of information
If color saturation is increased to improve color visibility in dark conditions, then color identification capability improves, but color accuracy deteriorates
Solution Approach 1:
The patent implements dynamic color parameter adjustment based on ambient light conditions. The system continuously monitors brightness levels and dynamically adjusts color saturation and temperature parameters accordingly. This dynamic approach allows the system to enhance color visibility when needed while maintaining color accuracy when ambient light is sufficient, resolving the contradiction between color identification capability and color accuracy.
Solution Approach 2:
The system applies different color compensation strategies to different color channels and different brightness conditions. By adjusting color parameters locally based on specific ambient light conditions and human eye sensitivity characteristics at different brightness levels, the system enhances color visibility in dark conditions while preserving overall color accuracy across various viewing scenarios.
3Loss of information
If color compensation is applied to enhance saturation, then display quality in dark conditions improves, but processing complexity increases
Solution Approach 1:
The system performs self-service by automatically detecting ambient light conditions and adjusting color parameters without requiring manual user intervention. The color compensation process is autonomously triggered based on brightness thresholds, and the system self-regulates the degree of saturation enhancement based on detected conditions, thereby improving display quality in dark conditions while keeping the processing framework relatively simple through automated decision-making.
