Solution Overview
Problem
Existing facility equipment management apparatuses lack the ability to change the screen color of an image display unit while maintaining appropriate contrast, making it difficult for users such as the elderly or visually impaired to recognize characters.
Innovation Solution
A facility equipment management apparatus that includes an image display unit, a display control unit, an operation input unit, a color palette database, and a color palette construction unit. The apparatus allows users to change the tint of the display image by designating color information corresponding to a hue value, enabling the display control unit to construct color component image data and display the image with the desired tint while maintaining appropriate contrast.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the screen color is changed to match the wall color, then the aesthetic integration is improved, but the contrast between text and background deteriorates
Solution Approach 1:
The patent applies local quality by maintaining different color characteristics for different regions of the display. The background color is adjusted to match the wall environment, while the text color is independently controlled to ensure sufficient contrast with the background, allowing each region to have optimal visual properties for its specific function
Solution Approach 2:
The system dynamically changes color parameters (hue, saturation, brightness) based on the detected wall color while maintaining a fixed contrast ratio between text and background. This allows the display to adapt to different wall colors while preserving text readability through parameter optimization
2Adaptability or versatility
If only wall color matching is implemented, then aesthetic integration is improved, but user accessibility for elderly and visually impaired deteriorates
Solution Approach 1:
The patent implements parameter changes by adjusting the brightness and saturation of text colors independently from the background color adaptation. This ensures that even when the background matches the wall color, the text maintains high visibility through optimized luminance and color intensity parameters
Solution Approach 2:
The system incorporates feedback mechanisms to monitor and adjust text readability. By detecting the wall color and calculating the appropriate text color parameters that maintain minimum contrast thresholds, the system provides feedback-driven adjustments to ensure accessibility for all users including elderly and visually impaired individuals
