Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If colorimetric values are stored without accompanying information, then storage is simple, but identification of colorimetric values corresponding to specific regions becomes difficult

Engineering Contradiction:
Improvedata storage structureVSAvoididentification of colorimetric values
Core Design Contradiction:
Device complexityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent introduces accompanying information (image data, positional information, identification data) as an intermediary that links colorimetric values to specific regions. This mediator enables accurate identification and association of colorimetric values with their corresponding target regions without complicating the core storage structure.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent adds a new dimension of data organization by storing colorimetric values together with accompanying information in a database. This multi-dimensional storage approach (colorimetric value + image data + positional information + identification data) enables precise region identification while maintaining systematic data management.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Device complexity

If manual identification of colorimetric values is used, then system complexity is low, but accuracy of color reproduction decreases

Engineering Contradiction:
Improvesystem complexityVSAvoidcolor reproduction accuracy
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The patent replaces manual mechanical identification processes with automated information processing systems. The terminal device automatically captures images, extracts positional information, identifies regions, and retrieves corresponding colorimetric values from the database, eliminating manual errors and improving color reproduction accuracy.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system implements feedback mechanisms where colorimetric values are measured, stored with accompanying information, and then retrieved for verification and adjustment. This closed-loop feedback ensures accurate color reproduction by continuously comparing measured values with target values and making necessary corrections.

Inventive Principle:
Principle #23Feedback

3Manufacturing precision

If colorimetric values for multiple regions are managed separately, then region-specific accuracy is improved, but time required for processing increases

Engineering Contradiction:
Improveregion-specific color accuracyVSAvoidprocessing time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent merges the management of colorimetric values for multiple regions into a single integrated database system. All colorimetric values are stored together with their associated accompanying information, allowing simultaneous management of multiple regions while maintaining region-specific accuracy through unique identification data.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system performs preliminary actions by pre-storing all colorimetric values with their accompanying information in the database before actual colorimetry operations. This pre-organization of data enables rapid retrieval and processing during execution, reducing processing time while maintaining region-specific accuracy.

Inventive Principle:
Principle #10Preliminary action

AI summary

A colorimetric system includes a terminal device and an information processing device. The terminal device includes a transmitter that associates a colorimetric value indicating a color of a colorimetry target subjected to colorimetry by a colorimetric device with accompanying information including at least one of a captured image of the colorimetry target and positional information of the colorimetry target and transmits the colorimetric value and the accompanying information. The information processing device includes a receiver that receives the colorimetric value and the accompanying information, and a display unit that displays the colorimetric value and the accompanying information in a state in which the colorimetric value is associated with the accompanying information.
