Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bank bill storage devices stack bills based solely on weight, often leaving gaps between bills without deformation, such as wrinkles, leading to inefficient storage.
Innovation Solution
A paper sheet storage device with a holding member, storing member, carrier unit, and pressing mechanism that abuts carrier belts on both sides of the paper sheet, allowing it to be pressed into a storage compartment without wrinkles, ensuring systematic storage without gaps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If bank bills are stacked only by their own weight without a pressing mechanism, then the device structure remains simple, but gaps are left between bills without deformation leading to inefficient storage
Solution Approach 1:
The pressing mechanism performs preliminary action by pressing the paper sheet between the carrier belts before it is stacked in the storage compartment. This pre-compression ensures the paper sheet is deformation-free and compact, eliminating gaps during subsequent stacking operations and improving storage efficiency without requiring continuous complex mechanisms
Solution Approach 2:
The carrier belts serve dual functions: they transport the paper sheet and simultaneously press it through their abutment. The pressing action is integrated into the existing carrier unit operation, allowing the same components to perform both transportation and compression functions, thereby improving storage efficiency without proportionally increasing device complexity
2Stress or pressure
If the carrier unit maintains abutment of both carrier belts during pressing, then the paper sheet is securely held, but the pressing mechanism cannot effectively compress the paper sheet
Solution Approach 1:
The system dynamically adjusts the abutment state of carrier belts during operation. Both carrier belts abut the paper sheet during transportation to ensure secure holding, but one carrier belt releases abutment during the pressing phase to allow effective compression. This dynamic state change enables the system to sequentially achieve both holding stability and pressing force requirements
Solution Approach 2:
The carrier belts operate with periodic action, alternating between abutment and release states according to the operational phase. During transportation, both belts maintain abutment; during pressing, one belt periodically releases. This rhythmic switching enables the system to achieve both secure holding during transport and effective compression during storage

AI summary
According to an aspect of an embodiment, a paper sheet storage device includes a holding member that includes a loading region into which a paper sheet is loaded; a storing member that is disposed adjacent to the holding member and that is used to store the paper sheet; a carrier unit that, in a state in which at least a single pair of carrier belts is abutting against both sides of the paper sheet, carries the paper sheet into the loading region; and a pressing mechanism that presses the paper sheet, which has been carried into the loading region, inside the storing member. In the paper sheet storage device, at the time of pressing of the paper sheet by the pressing mechanism, the carrier unit releases the abutment of one of the carrier belts with respect to the paper sheet.
