Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing colorblindness assistance technologies, such as ophthalmic wearables and optoelectronic glasses, fail to provide accurate and consistent color perception due to reliance on non-standardized color spaces like RGB and lack of calibration, leading to inadequate contrast improvement and delayed adaptation, while stand-alone color sensors do not utilize superior XYZ color space for precise color measurement.

Innovation Solution

A compact, standalone device with a color sensor, processor, and display that uses XYZ color space for real-time color measurement and correction, incorporating a light source, communication means, and energy storage, enabling instant color identification and adjustment for colorblind individuals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If ophthalmic wearables or coated glasses are used to assist color perception, then color vision assistance is provided, but accurate and consistent color perception is not achieved due to lack of calibration and reliance on non-standardized color spaces

Engineering Contradiction:

Improvecolor perception accuracyVSAvoidcolor measurement accuracy

Core Design Contradiction:

ReliabilityVSMeasurement precision

Solution Approach 1:

The patent replaces optical correction methods (glasses, contact lenses) with an electronic system comprising a color sensor, processor, and display/communication means. This substitution enables precise color measurement using XYZ color space and accurate real-time color information provision to colorblind users, resolving the contradiction between reliability and measurement precision.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the color space parameter from non-standardized RGB to standardized XYZ color space, and implements calibration procedures that adjust measurement parameters. This parameter change ensures accurate and consistent color perception by using internationally standardized colorimetry parameters rather than device-dependent RGB values.

Inventive Principle:

Principle #35Parameter changes

2Extent of automation

If stand-alone color sensors are used for color measurement, then color sensing is provided, but precise color measurement is not achieved due to lack of XYZ color space utilization

Engineering Contradiction:

Improvestand-alone operationVSAvoidcolor measurement precision

Core Design Contradiction:

Extent of automationVSMeasurement precision

Solution Approach 1:

The patent integrates multiple functions into a single stand-alone device: color sensing, XYZ color space calculation, color determination, and communication/display. This multi-functionality enables the device to operate independently while achieving precise color measurement through standardized XYZ color space, resolving the contradiction between automation extent and measurement precision.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If RGB color space is used for color correction, then color adjustment is provided, but accurate color identification is not achieved due to lack of calibration and standardized color space

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent changes the color space parameter from RGB to XYZ, implementing internationally standardized colorimetry. This parameter change enables accurate color identification by using calibration-based XYZ values that account for different light sources and viewing conditions, resolving the contradiction between adaptability and measurement precision.

AI summary

Devices, systems, and corresponding methods are provided for measurement of a color being scanned, and providing the name, description, or indication of the scanned color. Further, devices, systems, and corresponding methods are provided for adjustment of color in that another color than the scanned color is proposed and, e.g., displayed on the device, wherein the other color comes close or corresponds to the interpretation of the scanned color, though being different from the scanned color, for a colorblind person.
