Solution Overview

Problem

Current color selection methods for paint are limited by the accuracy of user computer displays and require physical retrieval or shipping of color samples, causing delays and uncertainty in the selection process.

Innovation Solution

A web-based system utilizing a database of digital color images and metadata, enabling users to select colors through search criteria, visualize them on three-dimensional representations, and access additional information for informed decisions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If physical color samples are used for selection, then color accuracy is improved, but time consumption and convenience deteriorate

Engineering Contradiction:
Improvecolor accuracyVSAvoidtime consumption
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent creates digital copies of physical color samples through standardized imaging processes. A controlled lighting system illuminates physical color standards, and an imaging device captures their appearance. These digital images are then stored and displayed, allowing users to view color information without handling physical samples, thus eliminating shipping and physical retrieval delays while maintaining color accuracy through standardized capture conditions.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent introduces an intermediary system consisting of standardized lighting devices and imaging devices that mediate between physical color standards and digital displays. This intermediary captures color information under controlled conditions and transfers it to digital format, serving as a bridge that preserves color accuracy while enabling remote digital viewing and selection.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If digital color images are displayed on user screens, then convenience and speed are improved, but color accuracy deteriorates due to display limitations

Engineering Contradiction:
Improveselection speedVSAvoidcolor accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The patent creates digital copies of physical color samples through standardized imaging processes. A controlled lighting system illuminates physical color standards, and an imaging device captures their appearance. These digital images are then stored and displayed, allowing users to view color information without handling physical samples, thus eliminating shipping and physical retrieval delays while maintaining color accuracy through standardized capture conditions.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent standardizes the capture parameters (lighting conditions, camera settings, background) to ensure consistent and accurate color representation across different displays. By controlling these parameters during image capture, the system compensates for display variations and maintains color fidelity in the digital domain.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If comprehensive color information is provided, then selection confidence is improved, but information processing complexity increases

Engineering Contradiction:
Improveselection confidenceVSAvoidinformation processing
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments color information into distinct categories: digital color images, metadata (color names, codes, formulations), and application examples. This segmentation allows users to access comprehensive information without being overwhelmed, as the system organizes data into manageable, searchable components that can be retrieved based on specific user needs.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent creates a multi-functional system that provides color selection, information retrieval, formulation data, and application examples through a single integrated platform. This universal approach consolidates multiple information types into one accessible interface, reducing overall system complexity compared to separate systems for each function.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A computer implemented method includes: providing a database of digital images of colors and metadata related to the colors; using one or more search criteria to identify one or more of the digital image colors; displaying the digital images of the identified colors; selecting a color of interest from the displayed colors; using the metadata to identify additional information related to the color of interest; displaying the digital image of the selected color and the additional information; and using the displayed digital image of the selected color and the additional information to make a final color selection. An apparatus that can be used to implement the method is also provided.
