Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display shows contents in various illumination environments, then the user can enjoy contents in different locations, but the user's visual sensitivity is degraded due to different colored illuminants
Solution Approach 1:
The patent changes the display parameters (white balance, brightness, color temperature) based on the detected illumination conditions. The control module adjusts these parameters dynamically according to the chromaticity and illuminance values obtained from the illuminance sensor, thereby maintaining visual comfort across different lighting environments while preserving visual sensitivity
Solution Approach 2:
The patent implements a feedback mechanism where the illuminance sensor continuously monitors the illumination environment, and the control module uses this information to adjust display parameters. This closed-loop feedback system ensures that the display adapts to changing light conditions while maintaining optimal visual sensitivity for the user
2Adaptability or versatility
If the display adjusts to match the incident light chromaticity, then the display adapts to the environment, but the image quality may be compromised when the incident light is not on a blackbody locus
Solution Approach 1:
The patent selectively adjusts display parameters based on the type of incident light. When the incident light chromaticity falls within a predetermined range (close to blackbody locus), the display adjusts white balance and color temperature to match the environment. When the chromaticity is outside this range, the display maintains standard image quality parameters, preventing degradation while preserving adaptability for appropriate conditions
Solution Approach 2:
The patent applies different display adjustment strategies based on the local characteristics of the incident light. By evaluating whether the incident light chromaticity is within the predetermined range, the system applies adaptive white balance adjustment only in suitable conditions, while maintaining fixed high-quality display parameters in unsuitable conditions, thus optimizing both adaptability and image quality locally
