Coin Deposit Processing With Partial Confirmation After Stacker Faults
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Banknote deposit processing machines without a temporary holding part face operational burdens when a stacker reaches maximum capacity during a transaction, requiring manual sorting and re-insertion of mixed banknotes due to faults like jams, increasing operator workload.
Innovation Solution
The currency deposit processor transfers and discriminates banknotes by denomination without temporary holding, performs partial confirmation of unconfirmed transactions, and adjusts data during recovery, reducing operator burden by automating the sorting process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a banknote deposit processing machine does not have a temporary holding part, then the configuration is simplified and the price is reduced, but when a fault occurs during deposit transaction, confirmed banknotes and unconfirmed banknotes become mixed and require manual sorting and re-insertion, increasing operator burden
Solution Approach 1:
The patent segments the deposit processing into distinct phases: normal deposit processing, full-capacity detection, banknote removal, and fault recovery. By introducing a temporary holding mechanism (hopper) that can store removed banknotes, the system separates confirmed transactions from unconfirmed ones, allowing selective re-processing without manual sorting.
Solution Approach 2:
The hopper acts as an intermediary storage component between the stacker and the deposit processing mechanism. When the stacker reaches full capacity, banknotes are transferred to the hopper instead of being permanently stored. This intermediary allows the system to pause and recover from faults without losing track of processed transactions.
2Quantity of substance
If the stacker reaches full capacity during deposit transaction, then the storage is optimized, but the deposit process must be interrupted and banknotes removed, causing mixing of confirmed and unconfirmed banknotes when faults occur
Solution Approach 1:
The system performs preliminary actions by detecting full capacity before it causes problems. When the stacker reaches maximum capacity, the system proactively stops the deposit process and transfers banknotes to the hopper, preventing potential mixing issues before they occur. This preliminary detection and response maintains transaction integrity.
Solution Approach 2:
The system dynamically adjusts its operation mode based on stacker capacity. When capacity is available, normal deposit processing continues. When full capacity is reached, the system transitions to a different mode where banknotes are diverted to the hopper. This dynamic adaptation allows the system to maintain productivity while managing storage constraints.
3Reliability
If banknotes are removed from full stacker and a fault occurs, then all banknotes must be re-inserted and re-processed, but this increases operation time and reduces efficiency
Solution Approach 1:
The system creates a logical copy of the deposit state by tracking which banknotes were processed before the full-capacity removal. During fault recovery, instead of re-processing all banknotes physically, the control unit references the stored transaction data to determine which banknotes need re-processing, significantly reducing recovery time.
Solution Approach 2:
The control unit continuously monitors the deposit process and maintains feedback about the state of each transaction. When a fault occurs, this feedback information is used to determine the exact point of failure and which banknotes require re-processing, enabling precise and efficient recovery without unnecessary re-handling of confirmed banknotes.

AI summary
A currency deposit processor transfers currencies set in a deposit part one by one, discriminates the currencies by denominations, stores the currencies in denominations in a storage part without temporarily holding the currencies, and confirms the deposited currencies for each transaction. A control unit is provided that, when one storage part reaches its maximum capacity with both currencies confirmed up to a previous deposit transaction and currencies unconfirmed in a current deposit transaction and a failure occurs after the filling-up currencies are removed, performs a special control, in which data on the currencies unconfirmed in the current deposit transaction and included in the filling-up currencies is calculated as a partial confirmation, and the data on the currencies calculated as the partial confirmation is added and reflected at a time of another deposit transaction after a fault recovery process.
