Paper Sheet Storage Device Dual Lifting Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing banknote storage devices face challenges in increasing storage capacity without increasing the device's size, as reducing the thickness of the mounting table interferes with rollers and requires complex adjustments to avoid interference, leading to increased space occupation.
Innovation Solution
A paper sheet storage device with a mounting table and support base, utilizing a first lifting lowering mechanism to move between high and low positions, and a second mechanism to lift the support base, ensuring the support base and first mechanism are within the mounting table's projection area, allowing for increased storage without enlarging the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the thickness of the mounting table is reduced to increase storage capacity, then the number of banknotes that can be stored increases, but the mounting table height decreases causing banknotes to fail contact with the pickup roller
Solution Approach 1:
The lifting function is segmented into two independent mechanisms: the first lifting lowering mechanism moves the mounting table relative to the support base, while the second lifting lowering mechanism moves the support base itself. This segmentation allows independent control of mounting table position and overall storage space height, resolving the contradiction between thin mounting table and reliable banknote contact.
2Reliability
If the mounting table height is extended upward to ensure banknote contact with the pickup roller, then reliable contact is achieved, but the lifting lowering mechanism interferes with the feeding roller and other members
Solution Approach 1:
The support base and first lifting lowering mechanism are disposed within the projection area of the mounting table, utilizing the vertical dimension and horizontal projection space efficiently. This dimensional arrangement allows the mechanisms to operate without interfering with the feeding roller and other members, while still achieving reliable banknote contact through the second lifting lowering mechanism.
3Device complexity
If the position of the lifting lowering mechanism is changed to avoid interference with the feeding roller, then interference is avoided, but the space occupied by the mechanism increases, leading to increased device size
Solution Approach 1:
The support base and first lifting lowering mechanism are nested within the projection area of the mounting table, similar to a nested doll structure. This nesting arrangement allows the mechanisms to be positioned without increasing the overall device footprint, while still avoiding interference with the feeding roller and other members through careful spatial arrangement.

AI summary
A paper sheet storage device includes a storage space in which paper sheet is stored; a mounting table that is provided in the storage space and on which the paper sheet is accumulated and placed; a support base that supports the mounting table; a first lifting lowering mechanism that lifts and lowers the mounting table between a high position and a low position relative to the support base; and a second lifting lowering mechanism that lifts and lowers the support base in the storage space. The support base and the first lifting lowering mechanism are disposed within a projection area in which the mounting table is projected on a plane orthogonal to a lifting lowering direction in which the support base is lifted and lowered by the second lifting lowering mechanism.
