Printed Material Shredder Control for Reliable Disposal Records
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing document management systems face reliability issues due to failures in reading two-dimensional codes by shredders, leading to incomplete disposal management of printed materials.
Innovation Solution
A printed material management system that includes a shredder capable of reading codes on printed materials, transmitting successful reads to a server for data update, and handling unsuccessful reads by discharging the materials without shredding, ensuring reliable management through data integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the shredder reads the two-dimensional code to manage printed material disposal, then the management reliability is improved, but the reading may fail causing incomplete disposal records
Solution Approach 1:
The system performs preliminary actions by printing a two-dimensional code containing the printed material ID onto the printed material before disposal. This code serves as pre-prepared information that enables the shredder to identify and record the disposal of the printed material, ensuring that the server can update the disposal status even when the printed material is destroyed.
Solution Approach 2:
The system creates a copy of the printed material ID information by encoding it into a two-dimensional code that is printed onto the printed material. This code serves as an informational copy that survives the shredding process or can be read before shredding, allowing the server to maintain accurate disposal records without requiring the original printed material to be physically preserved.
2Productivity
If the shredder automatically shreds printed materials after reading the code, then the disposal efficiency is improved, but the code reading may fail leading to incorrect disposal actions
Solution Approach 1:
The system implements feedback by having the shredder read the two-dimensional code on the printed material, transmit the read information to the server, and receive confirmation before executing the shredding action. The server updates the disposal status based on the successful reading of the code, providing feedback that ensures accurate disposal recording. If the code reading fails, the system can request re-reading or manual input, preventing incorrect disposal actions while maintaining efficient automated processing.

AI summary
A printed material management system includes a non-transitory computer readable medium storing a management program, a server, and a shredder. The management program is configured to cause a controller of a device in which the management program is installed to execute a print data acquisition process of acquiring print data, a generation process of determining a printed material ID, and generating a code by encoding the determined printed material ID, a printing process of printing the code and an image on a page corresponding to the printed material ID, and a transmission process of transmitting, to the server, a print log including the printed material ID and first data indicating that disposal is not completed. In a case where the code is successfully read, the shredder executes a rewriting process of transmitting a rewriting request associated with the printed material ID.
