Banknote Deposit Recovery Control Without Temporary Holding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Banknote deposit processing machines without temporary holding parts face operational burdens when faults occur during transactions, requiring manual sorting and reinsertion of mixed banknotes, increasing operator workload.
Innovation Solution
A currency deposit processor that transfers and discriminates banknotes by denomination without temporary holding, performs partial confirmation of unconfirmed transactions, and adjusts data for re-deposit processes upon fault recovery, reducing operator burden.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a banknote deposit processing machine does not have a temporary holding part to simplify configuration and reduce price, then device complexity and cost are reduced, but when a fault occurs during a deposit transaction after a previous transaction has been confirmed, both confirmed banknotes and unconfirmed banknotes are stored together in a mixed manner requiring manual sorting and recovery operations
Solution Approach 1:
The patent segments the deposit process into distinct states (confirmed and unconfirmed) and implements separate tracking mechanisms for each. The storage part is logically divided into regions that can be independently managed, allowing confirmed banknotes and unconfirmed banknotes to be distinguished even without physical separation. This enables automated recovery operations by identifying and retrieving only the necessary banknote portions.
Solution Approach 2:
The patent introduces an intermediary control mechanism that manages the transition between deposit transactions and tracks the state of banknotes. This intermediary system records which banknotes are confirmed and which are unconfirmed, enabling intelligent recovery operations that avoid manual sorting by automatically identifying the correct banknotes based on their transaction state.
2Device complexity
If confirmed banknotes and unconfirmed banknotes are stored together in stackers without temporary holding parts, then device complexity is reduced, but all banknotes must be removed and re-inserted when a fault occurs, increasing loss of time and productivity
Solution Approach 1:
The patent implements a feedback mechanism that continuously tracks the state of banknotes in the storage part. When a fault occurs, the system uses this feedback information to automatically determine which banknotes need to be recovered and in what order. This feedback-driven approach eliminates the need for complete removal and reinsertion of all banknotes, significantly improving recovery efficiency while maintaining the simple storage structure.
Solution Approach 2:
The patent performs preliminary actions by pre-tracking and recording the transaction state of each batch of banknotes before faults occur. This preliminary information gathering enables rapid recovery operations by having the system already know which banknotes are confirmed and which are unconfirmed, eliminating the need for time-consuming manual sorting and reinsertion during fault recovery.
3Quantity of substance
If a stacker reaches full capacity with both confirmed and unconfirmed banknotes, then storage utilization is maximized, but the deposit process must be interrupted to remove banknotes, causing loss of time and productivity
Solution Approach 1:
The patent introduces dynamic management of the storage part by allowing flexible removal of specific portions of banknotes based on their transaction state. When the storage part reaches capacity, the system can dynamically determine which unconfirmed banknotes to remove while retaining confirmed banknotes, enabling continuous deposit operations without complete emptying of the storage part. This dynamic approach maintains high storage utilization while ensuring process continuity.

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.
