Banknote Reject Handling With Temporary Storage Reuse

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional banknote processing devices face issues with rejected banknotes accumulating in a limited storage space, leading to device shutdowns and requiring frequent manual intervention for clearance, as they do not allow rejected banknotes to be reused in subsequent transactions.

Innovation Solution

Implementing a temporary storage unit that stores rejected banknotes during dispensing transactions, enabling these banknotes to be reused in subsequent transactions, thereby reducing the likelihood of the storage unit becoming full and minimizing the need for manual intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If rejected banknotes are stored in a limited storage space, then the device can handle rejected banknotes, but the storage unit becomes full frequently requiring manual clearance

Engineering Contradiction:

Improvecontinuous operation capabilityVSAvoidmanual intervention frequency

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The storage system is divided into multiple storage units (first storage unit and second storage unit) that can be selectively used. When the first storage unit becomes full, the system switches to the second storage unit, effectively segmenting the storage capacity to delay manual intervention and maintain continuous operation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Rejected banknotes are not permanently discarded in the reject box but are instead transferred to alternative storage units where they can be retained and potentially reused in subsequent transactions, recovering their value and reducing manual clearance frequency.

Inventive Principle:

Principle #34Discarding and recovering

2Ease of operation

If rejected banknotes are stored in a reject box, then rejected banknotes are separated from dispensed banknotes, but the device shuts down when storage is full

Engineering Contradiction:

Improverejected banknote managementVSAvoiddevice availability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The alternative storage units serve multiple functions: they can store rejected banknotes for later reuse, act as backup storage when the primary storage is full, and maintain device availability. This multi-functionality ensures both easy rejected banknote management and continuous device operation.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system preliminarily prepares alternative storage units before the reject box becomes full. When the first storage unit reaches capacity, the system proactively switches to the second storage unit, preventing shutdowns before they occur and maintaining device availability.

Inventive Principle:

Principle #10Preliminary action

3Loss of time

If a large capacity storage unit is used, then manual intervention frequency is reduced, but the device size increases

Engineering Contradiction:

Improvemanual clearance frequencyVSAvoiddevice footprint

Core Design Contradiction:

Loss of timeVSArea of stationary object

Solution Approach 1:

Instead of using one large capacity storage unit, the system segments storage into multiple smaller units (first storage unit and second storage unit) that can be selectively activated. This segmentation achieves equivalent total capacity without requiring a single large footprint, reducing the device's overall size while maintaining reduced manual intervention frequency.

Inventive Principle:

Principle #1Segmentation

4Productivity

If rejected banknotes are not reused, then transaction accuracy is maintained, but operational efficiency decreases

Engineering Contradiction:

Improvetransaction throughputVSAvoidrejected banknote accumulation

Core Design Contradiction:

ProductivityVSQuantity of substance

Solution Approach 1:

The system recovers rejected banknotes by storing them in alternative storage units instead of permanently discarding them in the reject box. These recovered banknotes can be reused in subsequent transactions, increasing transaction throughput while controlling the quantity of rejected banknotes that accumulate in the system.

Inventive Principle:

Principle #34Discarding and recovering

AI summary

A method for controlling a banknote processing device is a method in which in dispensing transaction, a storage feeds out banknotes; a recognition circuit recognizes the banknotes fed out from the storage; a conveyor transports banknotes recognized as non-rejected banknotes by the recognition circuit to an outlet, and transports banknotes recognized as rejected banknotes by the recognition circuit to a temporary storage; the temporary storage stores the rejected banknotes; if the temporary storage stores the rejected banknotes, in the dispensing transaction, the temporary storage feeds out the rejected banknotes as banknotes used for the dispensing transaction; and the conveyor transports the banknotes fed out from the temporary storage to the outlet.
