ATM Banknote Sorting for Selective Recovery and Replenishment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Managing the real-time inventory of mediums in automated teller machines (ATMs) is challenging for management companies when they are far away, leading to difficulties in replenishing only normal banknotes and handling rejection banknotes efficiently.
Innovation Solution
The ATM is equipped with a recovery transit cassette for recovering normal banknotes from deposit and recycle cassettes and a replenishment transit cassette for replenishing the machine with normal banknotes, using an identification unit to sort and control the conveyance path for efficient medium management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the management company is far away from the automated teller machine, then the machine can be installed in more locations providing customer convenience, but it becomes difficult to manage and monitor the amount of mediums in real time
Solution Approach 1:
The patent implements a communication system between the ATM and the management company that provides real-time feedback on medium inventory levels. The ATM automatically transmits medium quantity information to the management company, enabling remote monitoring and timely replenishment decisions without requiring constant manual intervention or physical presence at the machine location.
2Productivity
If all banknotes in the transit cassette are used for replenishment, then the replenishment process is simplified, but it becomes difficult to selectively replenish only normal banknotes and handle rejection banknotes separately
Solution Approach 1:
The patent divides the transit cassette into multiple compartments: a first transit cassette for normal banknotes and a second transit cassette for rejection banknotes. The identification unit automatically sorts banknotes as they are transferred from the replenishment cassette, directing normal banknotes to the first transit cassette and rejection banknotes to the second transit cassette. This segmentation enables selective handling and separate processing of different banknote types while maintaining efficient automated operation.

AI summary
An automated teller machine includes: a main body; a reception unit; an identification unit; a recycle cassette; a reject cassette; a deposit cassette; a utility cassette; a conveyance path through which a medium is conveyed; and a control unit. The control unit controls the conveyance path such that when the medium is recovered through the recovery transit cassette, the medium recognized as the normal banknote by the identification unit, among mediums stored in the deposit cassette and the recycle cassette, is recovered to the recovery transit cassette, and when the medium is replenished through the replenishment transit cassette, the medium recognized as the rejection banknote by the identification unit, among replenishment mediums stored in the replenishment transit cassette, is replenished to the utility cassette.
