Document Administration System Using QR Code Discrimination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current document administration systems lack efficient methods for managing and tracking the reuse, recycling, and security disposition of sheets printed with erasable ink, particularly in terms of administering image data and ensuring secure handling of sensitive information.
Innovation Solution
A document administration system that integrates a Multi Function Peripheral (MFP) with a print server, decoloring device, and QR code technology to administer and manage sheets by forming a discrimination information image, allowing for secure tracking and handling of printed documents, including erasable ink usage and secure disposal processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If sheets are printed with erasable ink for reuse, then resource efficiency is improved, but tracking and administration of image data becomes more difficult
Solution Approach 1:
The patent uses QR codes as digital copies of administrative information that can be attached to physical sheets. These QR codes contain or link to image data identifiers, allowing the system to track and administer image data associated with each sheet without interfering with the erasable nature of the printed content. The QR code serves as a persistent digital record that survives the erasure of the actual image.
Solution Approach 2:
The patent introduces an administration server as an intermediary between the printing system and the sheet lifecycle management. This server stores and manages the relationship between QR codes, image data, and sheet identifiers, enabling automated tracking and administration of erasable printed materials throughout their lifecycle from creation to disposal or reuse.
2Reliability
If discrimination information images are printed on sheets, then sheet tracking capability is improved, but the sheets require additional processing steps
Solution Approach 1:
The patent applies QR codes to sheets during the initial printing process, before the sheets enter circulation. The discrimination information (QR code) is printed alongside or on the same sheet as the main content, eliminating the need for separate attachment steps. This preliminary integration ensures that tracking information is already in place when the sheet is created.
Solution Approach 2:
The patent merges the discrimination information (QR code) with the main printed content on the same sheet. Rather than requiring separate tracking devices or additional processing steps to attach identifiers, the system combines the functional printed content with the administrative QR code on a single sheet, streamlining the overall process.
3Productivity
If QR codes are used for sheet identification, then administration efficiency is improved, but the system requires integration with existing printing infrastructure
Solution Approach 1:
The patent designs the QR code system to be universally compatible with existing printing infrastructure. The MFP (Multi-Function Peripheral) can both print the main content and generate/print the QR codes using its existing printing capabilities. The administration server uses standard QR code reading and data processing functions, making the system adaptable to various printing environments without requiring specialized hardware.

AI summary
A document administration system includes an administration unit, a discrimination information image discriminating unit, and an image forming apparatus which, forms an image on a recording medium in case that the discrimination information image discriminating unit discriminates that the recording medium has the discrimination information image before the image is formed on the recording medium, and forms the image and the discrimination information image based on the discrimination information connected to the image on the recording medium in case that the discrimination information image discriminating unit discriminates that the recording medium does not have the discrimination information image before the image is formed on the recording medium.
