Solution Overview

Problem

Existing colorimetric systems fail to efficiently identify and prompt users to perform colorimetry on missing colors within a color group, leading to incomplete data sets and user errors.

Innovation Solution

A colorimetric system that includes a comparison processing unit to identify colors not subjected to colorimetry and a display processing unit to display these colors, ensuring that all colors in a group are properly analyzed by determining the next color to be measured and prompting the user accordingly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the user performs colorimetry manually without system guidance, then the operation process is simple, but incomplete colorimetry data is generated and user errors occur

Engineering Contradiction:

Improveoperation process simplicityVSAvoidcolorimetry data completeness

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system implements feedback by comparing the set of colors subjected to colorimetry with the target color group, identifying missing colors, and displaying prompts to guide the user to complete the colorimetry process. This feedback loop ensures data completeness while maintaining operational simplicity.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system acts as an intermediary between the user and the colorimetry process by automatically tracking which colors have been measured and which remain, providing guidance without requiring complex user intervention. This mediator function resolves the contradiction by handling the complexity of data tracking internally while keeping the user interface simple.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the system checks all colors after colorimetry, then data completeness is improved, but additional processing time is required

Engineering Contradiction:

Improvecolorimetry data completenessVSAvoidcolorimetry processing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary action by maintaining a record of colors subjected to colorimetry during the measurement process itself, rather than performing a separate comprehensive check after all measurements are complete. This allows the system to identify missing colors immediately when the colorimetry process ends, reducing additional processing time while ensuring data completeness.

Inventive Principle:

Principle #10Preliminary action

3Measurement precision

If the system provides detailed guidance on which colors to measure, then measurement accuracy is improved, but system complexity increases

Engineering Contradiction:

Improvecolorimetry accuracyVSAvoidsystem structure complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The system extracts only the essential information needed for guidance - the identity of missing colors from the target group - and displays this selectively to the user. Rather than providing comprehensive system state information or complex processing details, the system takes out and presents only the specific guidance needed (which colors remain to be measured), thereby maintaining measurement precision while limiting system complexity exposure to the user.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

A colorimetric system includes a comparison processing unit that performs a process of a comparison between a color value of a color that was subjected to colorimetry by a colorimetric unit that performs colorimetry and a color value of a reference color, wherein the comparison processing unit performs a display process of making notification of a comparison processing result and a color to be subjected to colorimetry next that is a color that is not subjected to colorimetry.
