Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing confidential document recycling systems face increased workload and mis-sorting issues due to manual sorting of used papers, which affects the quality of recycled paper production.
Innovation Solution
A sheet collection device equipped with a discrimination portion to identify paper types, transport portion to sort papers into appropriate containers, accumulation portion to track storage amounts, and notification portion to predict and notify collection times, thereby automating the sorting process and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual sorting of discharged used paper is performed by worker, then the system can operate without complex equipment, but the workload is increased and mis-sorting tends to occur
Solution Approach 1:
The sheet collection device performs automatic sorting through a discrimination portion that identifies paper types and a transport portion that moves sheets to appropriate containers, eliminating the need for manual worker intervention and enabling the system to sort papers autonomously
Solution Approach 2:
The patent replaces manual mechanical sorting with an automated system comprising a discrimination portion using sensors or image recognition, and a transport portion using conveyors or robotic mechanisms, substituting human labor with automated mechanical and electronic systems
2Device complexity
If manual sorting of discharged used paper is performed by worker, then the system structure remains simple, but mis-sorting tends to occur affecting paper quality
Solution Approach 1:
The discrimination portion automatically identifies paper types through optical sensors, image recognition, or other detection methods, and the transport portion autonomously directs sheets to the correct containers, eliminating human error and ensuring consistent, accurate sorting
Solution Approach 2:
The system incorporates an accumulation portion that tracks storage amounts and a notification portion that monitors container fill levels, providing feedback to optimize sorting operations and prevent overflow, thereby maintaining high sorting accuracy and reliability
3Loss of time
If storage amount tracking and prediction notification system is implemented, then collection timing is optimized, but device complexity increases
Solution Approach 1:
The accumulation portion continuously monitors storage amounts in containers and the notification portion uses this data to predict when containers will be full, sending notifications to optimize collection timing and prevent overflow through closed-loop feedback control
Solution Approach 2:
The notification portion predicts future storage states based on current accumulation data and sends advance notifications before containers reach capacity, enabling proactive scheduling of collections and optimizing time management

AI summary
A sheet collection device includes a discrimination portion that discriminates the type of sheet, a plurality of containers that store sheets, a transport portion that transports the sheets to any one container from among the plurality of containers based on the discrimination result by the discrimination portion, an accumulation portion that accumulates progress information of a storage amount of sheets in the container, and a notification portion that predicts a time at which the storage amount of the sheets that are stored in the containers based on the progress information reaches a first predetermined amount and notifies the predicted time to a terminal device.
