Solution Overview

Problem

Existing bag processing apparatuses face challenges in efficiently identifying the cause of defects, often requiring manual visual inspection which is slow and prone to errors, and can lead to misalignment of components and new defects when operating speed is reduced for inspection.

Innovation Solution

A bag processing apparatus equipped with a defect detection unit and an imaging unit that captures video data of the defect location, allowing for analysis of the video data to identify the cause of defects, thereby eliminating the need for manual visual inspection and maintaining normal operating speeds.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual visual inspection is used to check defect causes, then defect causes can be identified, but the apparatus operating speed must be reduced to a visually perceptible level

Engineering Contradiction:
Improvedefect cause identification accuracyVSAvoidapparatus operating speed
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The patent replaces manual visual inspection with an automated imaging system that captures video data of the apparatus during normal high-speed operation. The imaging unit records defect causes without requiring the apparatus to slow down, substituting human visual perception with mechanical/optical detection systems that can operate at full speed.

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

Solution Approach 2:

The patent creates a visual copy (video data) of the apparatus operation and defect occurrences. Instead of directly observing the fast-moving apparatus, the system captures images and videos that can be analyzed later, allowing defect cause identification without interrupting or slowing the normal operation.

Inventive Principle:
Principle #26Copying

2Measurement precision

If the apparatus operating speed is reduced for visual inspection, then defect causes can be observed, but components may become misaligned and new defects may occur

Engineering Contradiction:
Improvedefect cause observation capabilityVSAvoidcomponent alignment and operational stability
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The patent eliminates the need to alter apparatus speed for inspection by using an automated imaging system. The imaging unit captures video data during normal operation, preventing any disruption to component synchronization and operational stability that would occur with manual observation.

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

Solution Approach 2:

The system performs preliminary recording of the apparatus state and defect occurrences during normal operation. By capturing video data in advance during high-speed operation, the system preserves the authentic operational state without any subsequent alterations or slowdowns that could cause misalignment.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If automated imaging is used to capture defect location video data, then defect causes can be identified without manual inspection, but device complexity increases

Engineering Contradiction:
Improvedefect identification speedVSAvoidimaging unit and video data processing system
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The imaging system is integrated into the apparatus itself, making the apparatus self-diagnostic. The imaging unit captures video data of its own operation and defect occurrences, eliminating the need for external manual inspection and reducing the need for separate complex analysis systems.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent introduces video data as an intermediary between the defect occurrence and the analysis process. Instead of directly observing complex fast-moving components, the system uses recorded video data as a mediator that can be analyzed at leisure, simplifying the analysis process while maintaining full operational speed.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A bag processing apparatus includes: a defect detection unit which detects occurrence of a defect in processing of a bag; and an imaging unit which is separately provided from the defect detection unit and takes images of a location creating a cause of occurrence of the defect to acquires video data, the vide data being stored in association with the occurrence of the defect.
