Slip Position Tracking via Dual Image Code Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing systems in manufacturing environments, such as printing factories, face challenges in managing work processes due to the inability to accurately track and display the position of slips with color codes captured by cameras, especially during system failures, which hinders efficient job progression and recovery operations.
Innovation Solution
An information processing system that includes image capturing devices and circuitry to manage the position of slips with first and second image codes, allowing for the display of slip positions and enabling the use of provisional slips with dummy codes during failures, facilitating recovery and job tracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If color codes are used on work instruction sheets to track job progress, then job progression can be monitored, but the system cannot distinguish between ordinary slips and provisional slips during failures
Solution Approach 1:
The patent segments the identification system by using different code types: ordinary color codes for normal operations and distinctive dummy codes (with specific patterns or markers) for provisional slips. This segmentation allows the system to differentiate between slip types while maintaining a unified tracking approach through image capture devices.
Solution Approach 2:
The patent utilizes color changes and visual distinctions in codes printed on slips. Ordinary slips have standard color codes while provisional slips have dummy codes with distinctive visual characteristics (different colors, patterns, or markers) that enable automatic differentiation by image recognition systems, ensuring reliable identification during system failures.
2Ease of operation
If the system uses standard color codes for all slips, then the tracking process is simple, but it cannot support recovery operations during system failures
Solution Approach 1:
The patent implements preliminary action by pre-printing distinctive dummy codes on provisional slips before system failures occur. These slips are prepared in advance with identifiable markers, so when a failure happens and recovery is needed, the system can immediately recognize and process provisional slips without requiring complex real-time differentiation logic.
Solution Approach 2:
The patent introduces dummy codes as an intermediary element that bridges ordinary tracking operations and failure recovery operations. These distinctive codes act as a mediator that enables the system to handle both normal job progression and abnormal recovery scenarios through a unified image recognition framework, maintaining simplicity while enhancing adaptability.
3Loss of information
If the system displays all slip positions continuously, then complete job tracking is achieved, but it increases system complexity and resource consumption
Solution Approach 1:
The patent applies local quality by making the display behavior context-dependent: the system continuously displays positions of ordinary slips for complete job tracking, but only displays positions of provisional slips when recovery operations are initiated or when specifically requested. This selective display approach maintains information completeness while reducing unnecessary system complexity and resource consumption during normal operations.

AI summary
An information processing system includes one or more image capturing devices and circuitry. The one or more image capturing devices capture a first slip and a second slip to generate one or more images. The first slip has a first image code corresponding to a first type of identification information thereon, and the second slip has a second image code corresponding to a second type of identification information thereon. The circuitry is to manage a position of the first slip based on the first image code recognized from the one or more images, manage a position of the second slip based on the second image code recognized from the one or more images, and display the position of the second slip in response to an operation performed by a user.
