Banknote Handling Apparatus Reconciliation via Code List Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current banknote handling systems face inefficiencies in reconciliation processes, particularly when dealing with large volumes of banknotes, as they require the feeding and counting of all banknotes to identify remaining banknotes, leading to prolonged processing times.
Innovation Solution
A banknote handling apparatus and method that utilize unique codes, such as serial numbers or barcodes, to create a code list of stored banknotes, allowing for the identification of remaining banknotes by reading and matching codes of sequentially fed banknotes against this list, thereby reducing the need to feed all banknotes and shortening the reconciliation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If all banknotes are fed and counted in the reconciliation process, then the identification of remaining banknotes is accurate, but the processing time becomes significantly long
Solution Approach 1:
The system creates a code list in advance that records the codes of all banknotes stored in each storage unit along with their storage positions. This preliminary recording allows the reconciliation process to identify remaining banknotes by comparing current banknote codes against the pre-established code list, without needing to feed and count all banknotes physically, thus reducing reconciliation time while maintaining identification accuracy
Solution Approach 2:
The code list serves as an intermediary data structure that bridges the physical banknotes and the system's record-keeping. By using this intermediate code list that maps codes to storage positions, the system can logically identify remaining banknotes without physical intervention, resolving the contradiction between accurate identification and time efficiency
2Adaptability or versatility
If the order of banknotes changes during storage, then the storage flexibility is improved, but the identification process becomes more complex
Solution Approach 1:
The system replaces the mechanical approach of physically tracking banknote positions and orders with an information-based system. By reading and recording the unique code of each banknote during storage and maintaining a code list that maps codes to storage positions, the system can identify remaining banknotes through code comparison rather than physical position tracking, simplifying the identification process even when banknote order changes
Solution Approach 2:
The system changes the identification parameter from physical position and order to unique code. By using the immutable code of each banknote as the primary identification parameter instead of its physical position or order in the stack, the system maintains accurate identification capability regardless of how the physical arrangement of banknotes changes during storage

AI summary
A banknote handling apparatus stores a code list in which codes of banknotes stored in a storage unit are arranged in order in which the banknotes are stored. The banknote handling apparatus reads the codes when the banknotes are sequentially fed from the storage unit, and checks a target group of the codes of N successive banknotes including the last fed banknote (N is a natural number not less than 2) against the code list. When the target group and a reference group of the codes of N successive banknotes in the code list match each other, the banknotes remaining in the storage unit after the feeding of the banknotes are identified by regarding one of the codes of the reference group in the code list as a boundary.
