Solution Overview

Problem

Existing image inspection systems require manual setting of inspection areas for each correct image, which is cumbersome and lacks usability, especially when dealing with a large number of images, and automatic setting can lead to increased user confirmation work.

Innovation Solution

An inspection system that includes a detection unit to automatically detect content areas in reference images, a display unit to set inspection levels, and an inspection unit to compare images based on these settings, allowing for automated and efficient inspection area setup.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual setting of inspection areas is performed for each correct image, then inspection accuracy is improved, but operation time and complexity increase significantly

Engineering Contradiction:
Improveinspection accuracyVSAvoidoperation time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The inspection area setting is performed automatically by the inspection apparatus itself through image recognition technology. The system reads the correct image, automatically identifies and sets the inspection area without requiring manual intervention, thereby resolving the contradiction between inspection accuracy and operation time.

Inventive Principle:
Principle #25Self-service

2Productivity

If automatic detection of inspection areas is implemented, then operation efficiency is improved, but user confirmation work increases

Engineering Contradiction:
Improveoperation efficiencyVSAvoiduser confirmation work
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The inspection area is automatically set in advance based on the correct image before the actual inspection process begins. This preliminary automatic setting eliminates the need for users to perform confirmation work during the inspection process, thereby improving both operation efficiency and ease of operation.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If inspection areas are automatically set for multiple correct images, then manual setting effort is reduced, but the number of inspection areas to confirm increases

Engineering Contradiction:
Improvemanual setting effortVSAvoidnumber of inspection areas
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The automatic inspection area setting function can be applied universally to multiple correct images simultaneously. The system processes each correct image automatically to set its corresponding inspection area, reducing manual setting effort across all images without requiring proportional increases in user confirmation work.

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