Recycled Sheet Traceability Using Printed History Access Codes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recycled sheet generation systems lack traceability of produced sheets, leading to low convenience in managing the history and production processes.
Innovation Solution
A system and method that includes a detection section to identify the type of material in the raw material, a fiber separation section to generate fibers, a sheet production section to produce sheets with a treatment agent, a printing section to print on the sheets, and a registration section to associate and register the sheet configuration components and production conditions, along with a history acquisition section to acquire and store this information for traceability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If history is managed by the management server, then the operation data is stored and analyzed, but the traceability of the produced sheets is low
Solution Approach 1:
The patent creates a physical copy of the history information by printing the access destination (such as a QR code or URL) directly on the sheet. This allows the sheet itself to carry the traceability information, improving traceability without requiring complex tracking systems throughout the entire supply chain.
Solution Approach 2:
The patent introduces an intermediary mechanism where the management server stores the comprehensive history data, and the sheet contains an access destination (QR code, URL) that serves as a mediator to retrieve this information. This separates the storage function from the presentation function, improving traceability while keeping the physical system simple.
2Loss of information
If comprehensive history data is stored and accessed, then traceability is improved, but the ease of operation is reduced
Solution Approach 1:
The patent creates a simplified access interface by printing the access destination (QR code, URL, or other identification information) directly on the sheet. Users can easily scan or read this information to access the comprehensive history data stored on the management server, making the system both traceable and easy to operate.
Solution Approach 2:
The patent transitions from a complex multi-step verification process to a simple one-dimensional access mechanism. Instead of requiring users to navigate through multiple systems or enter complex identification codes, the access destination is printed directly on the sheet, providing immediate access to history information through a single action (scanning or reading).

AI summary
A recycled sheet generation system includes a detection section that detects a type of material included in a raw material, a fiber separation section that generates fibers by separating the raw material, a sheet production section that produces a sheet by depositing a mixture in which a treatment agent is mixed with the fibers generated by the fiber separation section, a printing section that prints on the sheet, a history acquisition section configured to acquire, as history, a sheet configuration component based on the type of material that is included in the raw material and that was detected by the detection section and a sheet production condition, and a registration section that registers the sheet configuration component and the sheet production condition in association with each other. The printing section prints an access destination for accessing the registered sheet configuration component and the sheet production condition in a predetermined region of the sheet.
