Color Selection Input Device Non-Equal Hue Segments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional color selection devices for lighting systems use equal hue gradations, which do not effectively adapt to user preferences, limiting the ability to finely adjust preferred color settings and increasing user discomfort in selecting desired colors.
Innovation Solution
A color selection input device and method that divides hue gradations into non-equal segments, with larger segments for user-preferred hues and smaller segments for non-preferred hues, allowing for more precise and comfortable color selection, adaptable through mechanical or electronic means, including color wheels and software implementations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If equal hue gradation segments are used in color selection devices, then the device structure is simple and uniform, but the user preference adaptation is poor and color selection precision for preferred colors is limited
Solution Approach 1:
The patent applies local quality by dividing the hue gradation into non-equal segments where segments corresponding to user-preferred hues have larger angular ranges than segments for non-preferred hues. This creates localized expansion in the color selection space for preferred colors, allowing finer granularity and more precise selection in those regions while maintaining simpler segmentation elsewhere.
Solution Approach 2:
The patent segments the hue circle into multiple angular ranges based on user preference analysis. By segmenting the 360-degree hue cycle into distinct preference-based regions, the system can apply different resolution levels to different segments, improving overall color selection precision without requiring uniform high-resolution segmentation across the entire hue range.
2Adaptability or versatility
If non-equal hue segments are implemented, then user preference adaptation is improved, but the device complexity increases
Solution Approach 1:
The patent implements dynamics by making the hue segment configuration adaptable to user preferences rather than fixed. The system can dynamically adjust the angular ranges of different hue segments based on analyzed user preferences, allowing the color selection device to adapt to individual users' favorite colors and adjust the segmentation accordingly to provide optimized selection experience.
Solution Approach 2:
The patent changes the parameter of angular range assignment for hue segments based on user preference analysis. By varying the angular parameters of different segments according to which hues users prefer, the system achieves better adaptability to user preferences while managing device complexity through parameter-based configuration rather than structural complexity.
3Area of moving object
If larger segments are allocated to user-preferred hues, then the selection area for preferred colors is increased, but the overall color coverage may be reduced
Solution Approach 1:
The patent applies local quality by concentrating larger angular segments for user-preferred hues while maintaining smaller segments for non-preferred hues. This localized expansion provides users with a larger selection area for their preferred colors, improving user satisfaction and ease of selection for those colors while still preserving coverage of the complete color spectrum through the smaller segments.

AI summary
The invention relates to color selection input, for example by means of a color selection wheel or pad, particularly for a lighting system. The invention provides color selection means (10) representing selectable colors in terms of hue gradation (12) along a direction thereof, wherein the hue gradation is adapted to user preferences in that the hue gradation is divided into non-equal segments (20, 22) with segments of user preferred hue (20) larger than segments of non user preferred hue (22). The invention has the main advantage that the input of a color selection may be better adapted to user preferences.
