Mixed-Denomination Money Storage Feedback for Faster Withdrawals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing money handling apparatuses face inefficiencies due to biased storage of coins, leading to increased withdrawal times and reduced ease of withdrawing desired denominations, potentially inhibiting smooth operation.
Innovation Solution
A control unit in the money handling apparatus compares the number of each coin denomination with predetermined thresholds, outputs information on excess or deficiency, and adjusts operations to maintain balanced storage, including preferential collection and ejection of coins to ensure smooth operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If coins are stored in a mixed storage unit without denomination restrictions, then the storage capacity is maximized, but the withdrawal time increases and operational smoothness deteriorates due to biased storage of certain denominations
Solution Approach 1:
The control unit continuously monitors the number of coins of each denomination in the mixed storage unit and compares it with a predetermined appropriate number. When the coin count deviates from the appropriate number (either exceeding or falling below), the system provides feedback by displaying this information to the user, prompting corrective action to restore balanced storage and maintain efficient withdrawal operations
Solution Approach 2:
The system establishes predetermined appropriate numbers for each denomination in advance, based on expected withdrawal patterns. By proactively monitoring and alerting users before severe imbalance occurs, the system enables preliminary corrective actions that prevent withdrawal time from increasing significantly, maintaining operational smoothness
2Adaptability or versatility
If the storage unit accepts all denominations without restriction, then the versatility of the storage unit is improved, but the ease of withdrawing desired denominations decreases due to biased storage distribution
Solution Approach 1:
The control unit provides real-time feedback on the distribution of different denominations by displaying whether the count of each denomination exceeds or falls below the predetermined appropriate number. This enables users to understand the current storage state and make informed decisions about which denominations to add or remove, thereby maintaining ease of withdrawal while preserving storage versatility
Solution Approach 2:
The system dynamically adjusts the operational parameters by changing the predetermined appropriate numbers for each denomination based on withdrawal patterns and storage capacity. This allows the system to optimize the balance between storage flexibility and withdrawal ease, adapting to different operational scenarios while maintaining smooth operations

AI summary
To increase the possibility of operating a money handling apparatus smoothly, a money handling apparatus according to an aspect of the present disclosure includes: at least one mixed storage unit configured to store a plurality of types of money; and a control unit that, for each type of money, compares the number of money stored in the mixed storage unit with a predetermined number set for the type of money, outputs information indicating a first situation in a case of the first situation, and outputs information indicating a second situation in a case of the second situation, the first situation being a situation where the number of money is larger than the predetermined number set for the type of money, the second situation being a situation where the number of money is smaller than the predetermined number set for the type of money.
