Single Cassette Multi-Denomination Currency Sorting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Self-service terminals (SSTs) require a large footprint and high maintenance costs due to the need for multiple cassettes, each dedicated to a specific currency denomination, which is inefficient and wasteful, especially when not all denominations are used simultaneously.
Innovation Solution
Implementing a single cassette that can dispense multiple denominations by using a note stack data system to track and mix different denominations within the same cassette, allowing for efficient dispensing without manual sorting or partitioning, and dynamically adjusting the distribution of notes between cassettes based on usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple cassettes are used, each dedicated to a specific currency denomination, then currency dispensing can be performed for multiple denominations, but the footprint and maintenance requirements increase significantly
Solution Approach 1:
A single cassette is designed to handle multiple currency denominations through automated sorting mechanisms. The cassette includes a receiver for accepting currency notes and a sorter that can identify and separate different denominations, allowing one cassette to perform the function previously requiring multiple dedicated cassettes.
Solution Approach 2:
The system employs automated detection and sorting mechanisms within the cassette that can identify currency denominations and organize them without human intervention. The processor analyzes currency characteristics and controls the sorting mechanism to separate notes by denomination automatically.
2Adaptability or versatility
If multiple cassettes are used for different denominations, then all currency types can be handled, but maintenance costs and operational complexity increase
Solution Approach 1:
Multiple denomination handling capabilities are merged into a single cassette unit. The cassette integrates the receiver, sorter, and storage functions that previously required separate cassettes for each denomination, reducing the overall number of components and simplifying management.
Solution Approach 2:
Manual sorting and physical partitioning of cassettes by denomination is replaced with an automated electronic sorting system. The processor controls the sorting mechanism based on detected currency characteristics, eliminating the need for manual intervention and physical separation structures.
3Ease of operation
If cassettes are partitioned to hold specific denominations, then organization is improved, but space is wasted when partitions are not usable for given denominations
Solution Approach 1:
The cassette organization is made dynamic rather than static. Instead of fixed partitions for specific denominations, the system uses movable sorting mechanisms that can adapt to different denomination mixes. The sorter can reconfigure based on the actual currency present, maximizing space utilization while maintaining organization.
Solution Approach 2:
Different regions of the cassette are utilized based on the specific denominations present rather than having predetermined fixed assignments. The sorting mechanism directs different denominations to different local areas within the cassette as needed, optimizing space usage for the actual currency mix being handled.

AI summary
Disclosed are systems and methods for recycling currency. The systems and methods may include receiving, at a self-service terminal, a plurality of currency notes; sorting, by the self-service terminal, the plurality of currency notes by denomination; and dispensing, by the self-service terminal, a subset of the plurality of currency notes.
