Folding Deviation Correction via Surface Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for automatically detecting folding deviations in a medium folded by a folding device cannot determine which surface is being read, making it impossible to specify the correction direction for the folding deviation, thus hindering accurate adjustment of the folding position.
Innovation Solution
An information processing apparatus that includes a processor configured to read images of both surfaces of a folded medium, discriminate between the surfaces based on identification images, and determine the correction direction of the folding deviation by identifying whether the deviation occurs on the first or second surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If automatic detection of folding deviation is implemented without surface identification, then detection capability is improved, but correction direction cannot be specified
Solution Approach 1:
The system performs preliminary action by marking the medium with identification information before folding. This allows the detection unit to later identify which surface is being read and determine the correct correction direction, resolving the information loss problem while maintaining automation.
Solution Approach 2:
The invention introduces an intermediary element (identification mark/surface identification unit) that bridges the gap between automatic detection and correction direction specification. This intermediary carries surface identification information through the folding process, enabling the system to determine correction direction without manual intervention.
2Productivity
If the medium is folded for detection, then detection efficiency is improved, but correction direction cannot be determined
Solution Approach 1:
The surface identification mark is applied in advance before folding, preserving surface orientation information throughout the folding process. This allows efficient detection of folded media while maintaining the ability to determine correction direction.
Solution Approach 2:
The invention uses visual identification marks (which may involve color or pattern changes) on different surfaces of the medium. These marks remain distinguishable after folding, enabling the detection system to identify the read surface and determine correction direction efficiently.
3Measurement precision
If surface identification is added to the detection system, then correction direction can be specified, but system complexity increases
Solution Approach 1:
Surface identification marks are applied in advance using simple marking mechanisms, avoiding the need for complex real-time surface identification systems. This maintains measurement precision while minimizing added system complexity.
Solution Approach 2:
The invention uses visual copies or representations of surface identification information (marks, patterns, or colors) that can be easily detected by image processing. This approach achieves precise surface identification without requiring complex physical modification of the detection system.

AI summary
An information processing apparatus includes: a processor is configured to: read an image of at least one of a first surface or a second surface of a medium with the medium folded; discriminate whether the image is of the first surface or the second surface based on an identification image in the image; specify, based on the image, a surface on which a folding deviation occurs; and determine a correction direction of the folding deviation according to whether the surface on which the folding deviation occurs is the first surface or the second surface.
