Cash Transaction Fee Control for Denomination Inventory Balancing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems fail to effectively manage and adjust the quantity of money stored in a store, particularly when there are shortages or surpluses, leading to inefficiencies and increased reliance on cash-in-transit services due to mismatched denominations and uncontrolled deposit amounts.
Innovation Solution
A transaction system that includes a money handling unit for recognizing and counting money by denomination, a processing unit for calculating transaction fees based on predefined rates, and a management apparatus for managing inventory and transaction conditions, allowing for the setting of incentive or commission rates for each denomination to adjust the quantity of money stored.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If customers deposit money into the money handling apparatus to accumulate funds, then the store can reduce reliance on cash-in-transit services, but the system cannot effectively adjust the quantity of money stored when denomination mismatches occur
Solution Approach 1:
The transaction fee rate is made dynamically adjustable based on the current money inventory levels. When a specific denomination becomes insufficient, the system automatically increases the transaction fee rate for that denomination to encourage customers to deposit more of that specific type, thereby dynamically adapting the money accumulation strategy to current needs.
Solution Approach 2:
The system changes the parameter of transaction fee rate according to the quantity of money held for each denomination. By varying this parameter, the system can shift customer deposit behavior to match the store's inventory requirements, resolving the adaptability issue.
2Reliability
If the store requests cash-in-transit services to manage money shortages or surpluses, then the store can maintain adequate change funds, but service fees are incurred
Solution Approach 1:
The system enables customers to voluntarily deposit money into the apparatus based on incentive structures. Instead of relying on external cash-in-transit services, the store creates a self-sustaining mechanism where customers are motivated to contribute to the money supply through transaction fee incentives, thereby eliminating the need for costly external services.
Solution Approach 2:
The system implements feedback by monitoring the quantity of money held for each denomination and automatically adjusting transaction fee rates accordingly. This closed-loop control ensures that the store maintains adequate change funds while minimizing external service dependencies through automated internal adjustment.
3Quantity of substance
If money is deposited without denomination control, then the store receives funds, but the deposited money may not match the store's actual needs
Solution Approach 1:
The system applies different transaction fee rates to different denominations based on their specific inventory levels. Rather than treating all money deposits uniformly, the system targets specific denominations that are in short supply, encouraging customers to deposit the exact types needed by the store through differentiated incentive structures.

AI summary
In order to adjust the amount of money in a transaction apparatus installed in a store, a transaction system includes: a money handling unit that receives money, and recognizes and counts the received money to acquire a first total amount of the received money and a quantity of money for each denomination; a memory that stores therein a transaction condition including a transaction fee rate previously set for each denomination; and a processing unit that calculates, for each denomination, an amount of money by multiplying the quantity of money for each denomination by the transaction fee rate, based on the quantity of money and the transaction condition, and performs processing on a transaction of the received money, based on the first total amount acquired by the money handling unit and on a second total amount calculated by summing up the calculated amounts of money for the respective denominations.
