Problem

Existing medium loading systems face image capturing failures due to undetected abnormalities in the image capturing unit, such as damage or foreign matter, when capturing images of recording media.

Innovation Solution

A medium loading system with a supplier that levitates and separates recording media using air, an image capturing unit, and a processor that detects abnormalities based on changes in captured images, allowing for controlled air supply and image capture adjustments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the image capturing unit is used to capture images of recording media without abnormality detection, then image capturing can be performed continuously, but image capturing failures occur due to undetected abnormalities

Engineering Contradiction:
Improvecontinuous image capturingVSAvoidimage capturing failure
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system performs preliminary abnormality detection by capturing images of a target object before actual image capturing of recording media begins. This preliminary action identifies potential abnormalities in the image capturing unit, allowing the system to prevent image capturing failures before they occur during production operation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

A target object is introduced as an intermediary for abnormality detection. The target object serves as a test subject that allows the system to evaluate image capturing unit performance without affecting actual recording media. This intermediary enables safe and effective preliminary testing.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If abnormality detection is performed using a target object, then image capturing reliability is improved, but device complexity increases

Engineering Contradiction:
Improveimage capturing reliabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The image capturing unit serves multiple functions: it captures images of the target object for abnormality detection and captures images of recording media for actual operation. This multi-functionality eliminates the need for separate detection and production systems, maintaining reliability improvement without proportionally increasing device complexity.

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

Solution Approach 2:

The abnormality detection function is merged with the existing image capturing system by using the same image capturing unit and processor. The target object detection process is integrated into the operational workflow, combining diagnostic and production functions into a unified system.

Inventive Principle:
Principle #5Merging (Combining)

3Manufacturing precision

If air supply is adjusted based on distance measurement, then medium separation precision is improved, but measurement precision requirements increase

Engineering Contradiction:
Improvemedium separation precisionVSAvoiddistance measurement precision
Core Design Contradiction:
Manufacturing precisionVSMeasurement precision

Solution Approach 1:

The system uses feedback from image analysis to determine the distance between recording media. The processor analyzes captured images to calculate spacing, and this feedback information is used to adjust air supply parameters. This closed-loop feedback mechanism enables precise medium separation while using standard imaging capabilities.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system replaces direct mechanical distance measurement with optical measurement using the image capturing unit. Instead of requiring specialized measurement devices, the system uses image processing to infer distance information, reducing measurement precision requirements while maintaining separation precision.

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