Bill and Coin Processing System with Automatic Fund Segregation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bill and coin processing systems lack efficient management and recycling capabilities, leading to increased operational burdens and errors, particularly in distinguishing between customer and shop funds, and in handling multiple denominations and transactions.
Innovation Solution
A bill and coin processing system with an interface unit for communication with a POS terminal, a money receiving unit, a discriminating unit for denomination identification, a storing/discharging unit for automatic selection and storage, and a control unit for controlled discharge, enabling automatic recycling and efficient management of funds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual cash collection and replenishment is performed each time a casher is replaced, then cash management can be done, but operational burden and errors increase
Solution Approach 1:
The change discharger automatically performs cash collection, counting, and replenishment operations without requiring manual intervention. The system self-manages the cash recycling process by automatically receiving money from customers, counting it, storing it in appropriate compartments, and replenishing change when needed, thereby eliminating the operational burden on cashers while maintaining accurate cash management
Solution Approach 2:
The manual mechanical process of cash handling is replaced with an automated electromechanical system. The change discharger uses sensors, motors, and control units to automatically perform cash reception, denomination identification, sorting, and replenishment operations, substituting human labor with automated machinery to reduce errors and operational burden
2Adaptability or versatility
If multiple denominations of bills and coins are recycled, then change discharge flexibility improves, but operation complexity increases
Solution Approach 1:
The change discharger is divided into multiple independent storage compartments, each dedicated to a specific denomination of bills or coins. This segmentation allows the system to handle multiple denominations simultaneously while simplifying the operation - each compartment can be independently managed, counted, and replenished without interfering with other denominations, thus maintaining flexibility while reducing operational complexity
Solution Approach 2:
The control unit acts as an intermediary that manages the complexity of handling multiple denominations. It receives instructions from the POS terminal, automatically determines which denominations are needed for change, coordinates the discharge from appropriate compartments, and manages replenishment logistics, thereby shielding the operator from the complexity of multi-denomination management
3Productivity
If automatic recycling of received money is implemented, then operational efficiency improves, but distinction between customer and shop funds becomes difficult
Solution Approach 1:
The change discharger automatically performs the distinction and separation of customer funds and shop funds at the moment of cash reception. By preliminarily identifying and segregating these funds into appropriate storage compartments based on denomination and ownership, the system maintains clear fund distinction while enabling automatic recycling, thus improving operational efficiency without losing information about fund ownership
Solution Approach 2:
The system uses feedback from the POS terminal and its own sensors to continuously track and distinguish between customer-deposited money and shop money. The control unit receives information about transactions and automatically adjusts the recycling process to maintain proper fund separation, providing real-time feedback on fund status and ensuring that automatic recycling does not compromise fund ownership information

AI summary
A bill and coin processing system including a bill and coin processing apparatus having: an interface unit capable of exchanging information via a communication unit with the point-of-sales terminal machine; a money receiving unit receiving money by way of a price of a commercial product; a discriminating unit discriminating between at least denominations of the bills and coins received from the money receiving unit; a storing/discharging unit stored with the received bills and coins on the basis of a result of the discrimination made by the discriminating unit and capable of discharging the bills and coins by giving a discharge instruction to the bill and coin processing apparatus from the point-of-sales terminal machine; a money discharging unit discharging the bills and coins outside a machine, which have been discharged from the storing/discharging unit; and a control unit controlling the money discharging unit to discharge the bills and coins from the storing/discharging unit on the basis of a discharge instruction accepted by the interface unit and given to the bill and coin processing apparatus from the point-of-sales terminal machine.
