Banknote Handling Reconciliation via Marked Subset Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing banknote handling machines face inefficiencies in the reconciliation process due to irregular transport of banknotes, leading to uncertain storage and dispensing, which prolongs machine downtime and requires extensive manual counting.
Innovation Solution
A banknote handling apparatus with a first storage unit that winds banknotes on a reel, a second storage unit, a transport unit, and a control unit that allows selective feeding and recognition of banknotes based on inventory marks, reducing the need to count all banknotes and streamlining the reconciliation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If all banknotes are fed out for reconciliation to ensure accurate inventory determination, then measurement precision is improved, but loss of time increases significantly
Solution Approach 1:
The patent extracts a subset of banknotes (those with inventory marks) from the entire banknote stack for reconciliation. Instead of feeding all banknotes, the system identifies and processes only those marked banknotes that indicate inventory changes, thereby maintaining measurement precision while dramatically reducing the time required for reconciliation.
Solution Approach 2:
The system performs preliminary marking of banknotes during the depositing process. Inventory marks are placed on banknotes at the time of storage, so during reconciliation, only marked banknotes need to be processed. This preliminary action eliminates the need to recount all banknotes, reducing reconciliation time while preserving inventory accuracy.
2Reliability
If banknotes are stored with gaps between them to prevent irregular transport, then reliability is improved, but device complexity increases due to additional control mechanisms
Solution Approach 1:
The patent applies gaps between banknotes locally at specific positions (after certain数量的 banknotes) rather than uniformly between all banknotes. This localized application of gaps maintains transport reliability for critical sections while minimizing the overall complexity of the storage and feeding mechanism.
Solution Approach 2:
The patent introduces an inventory mark as an intermediary element that mediates between the banknotes and the reconciliation system. These marks serve as indicators that simplify the control mechanism by providing clear identification points without requiring complex sensing or tracking systems for each individual banknote.
3Volume of moving object
If winding storage is used to downsize the apparatus, then volume is reduced, but manufacturing precision requirements increase to ensure proper banknote winding and gap control
Solution Approach 1:
The patent segments the banknote storage into discrete sections with controlled gaps between them. By dividing the continuous winding into segmented sections with predetermined gaps, the system reduces the precision requirements for the overall winding process while maintaining compact apparatus size. Each segment can be independently controlled and marked.

AI summary
A banknote handling apparatus (a banknote depositing/dispensing machine) includes: a first winding storage unit (a storage module); a second storage unit; a transport unit; a recognition unit; and a control unit configured to allow banknotes in the first storage unit to be fed and stored in the second storage unit, and thereafter allow the banknotes stored in the second storage unit to be fed and stored in the first storage unit, and recognized by the recognition unit, in order to perform a recognition process. The first storage unit stores the banknotes, while providing a mark associated with inventory amount information of the first storage unit. To perform the reconciliation process for the first storage unit, the control unit allows some of the banknotes stored in the first storage unit to be fed from the first storage unit, based on the mark, for recognition by the recognition unit, and determines an inventory amount of the first storage unit based on a result of the recognition and the inventory amount information associated with the mark.
