Banknote Deposit Guide Section Dynamics for Compact Foreign Object Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional banknote depositing and dispensing machines are bulky due to the need for large protective plates to prevent foreign objects from entering, making it difficult to achieve a compact design.
Innovation Solution
A banknote depositing and dispensing machine with a shutter, a pickup roller, a banknote guide section, and an upper guide section that moves to prevent foreign objects from entering and allows for a smaller casing by positioning the guide section and bill press to form a banknote accommodation space below the depositing port, with the upper guide section projecting out to block foreign objects when the shutter is open and retracting when closed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large protective plate is provided to prevent foreign objects from entering the gap between the top of the banknote depositing and dispensing section and the casing, then foreign object protection is improved, but the banknote depositing and dispensing section becomes bulky
Solution Approach 1:
The guide section is designed to be movable rather than fixed. It can move between a first position (when the shutter is open) where it projects outward to block foreign objects, and a second position (when the shutter is closed) where it retracts to minimize the size of the depositing and dispensing section. This dynamic positioning resolves the contradiction by providing protection only when needed.
Solution Approach 2:
The guide section is positioned in advance at the first position (projecting outward) before foreign objects can enter the gap. This preliminary positioning ensures that when the shutter is open, the guide section is already in place to block foreign objects, eliminating the need for large stationary protective plates.
2Reliability
If the bill press is moved in the direction of the banknotes to prevent damage from foreign objects, then protection is improved, but the size of the banknote depositing and dispensing section is determined by the movement mechanism placement
Solution Approach 1:
Instead of moving the bill press in the traditional manner, the guide section is made movable and positioned dynamically. The guide section moves with the shutter mechanism, projecting outward when the shutter is open to provide protection, and retracting when the shutter is closed. This eliminates the need for complex bill press movement mechanisms while maintaining protection.
3Ease of operation
If the depositing port is positioned closer to the user for convenience, then ease of operation is improved, but the gap between the port and casing allows foreign objects to enter
Solution Approach 1:
The guide section is dynamically positioned to project outward when the shutter is open, creating a blocking barrier in the gap between the depositing port and the casing. This allows the port to be positioned close to the user for convenience while the guide section provides on-demand protection against foreign objects entering through the inevitable gap.

AI summary
When depositing processing is performed, a banknote guide section and a bill press are separated from each other such that a banknote accommodation space formed between the banknote guide section and the bill press is positioned below a banknote depositing and dispensing port, a upper guide section is moved towards a pickup roller side and a input port shutter is opened. After the input port shutter has been closed, the upper guide section is moved towards a bill press side, and by moving the banknote guide section and the bill press towards the pickup roller side, the pickup roller, which is projected out into the accommodation space through a cutout in the banknote guide section, and which makes contact with the banknote, feeds the banknote out towards a conveying path.
