Solution Overview

Problem

Existing systems struggle to efficiently verify defects in the direction and order of images formed on multiple media combined at different timings, leading to inefficiencies in inspection processes.

Innovation Solution

An information processing system comprising a controller, image forming apparatus, and verification apparatus that acquires verification data and scans images to verify defects in direction and order using reduced-resolution scanning, allowing for efficient detection and correction of abnormalities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple media are subjected to image formation at different timings and retrospectively combined, then productivity is improved, but defects in direction and order become difficult to detect

Engineering Contradiction:

Improveimage formation efficiencyVSAvoiddefect detection difficulty

Core Design Contradiction:

ProductivityVSDifficulty of detecting and measuring

Solution Approach 1:

The system performs preliminary actions by generating verification data that includes direction and order information before the final inspection stage. This allows defects to be detected retrospectively even when media are formed at different timings and combined later, resolving the contradiction between improved productivity and defect detection difficulty.

Inventive Principle:

Principle #10Preliminary action

2Manufacturing precision

If comprehensive verification of direction and order is performed, then manufacturing precision is improved, but inspection time increases

Engineering Contradiction:

Improveimage verification accuracyVSAvoidinspection time

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The system creates verification data as a copy or reference model that includes expected direction and order information. This verification data is then compared against actual scanned images, enabling comprehensive verification without requiring complex real-time analysis, thus maintaining high manufacturing precision while reducing inspection time.

Inventive Principle:

Principle #26Copying

3Measurement precision

If high-resolution scanning is performed for verification, then measurement precision is improved, but use of energy increases

Engineering Contradiction:

Improveimage scanning accuracyVSAvoidscanning energy consumption

Core Design Contradiction:

Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The system changes the resolution parameter based on the verification needs. By adjusting the scanning resolution to an appropriate level rather than always using maximum resolution, the system achieves sufficient measurement precision for detecting direction and order defects while significantly reducing energy consumption during the scanning process.

Inventive Principle:

Principle #35Parameter changes

AI summary

An information processing system includes a processor configured to acquire verification data of an inspection target object consisting of plural media after image formation, and images scanned from the inspection target object by an image scanning portion, and verify at least one of a defect in a direction or a defect in an order of the images of the inspection target object based on the images scanned by the image scanning portion and on the verification data.
