Money Handling Coin Sorting for Change Fund Replenishment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional money handling apparatuses face inefficiencies in preparing change funds due to the need to sift through a large number of mixed denomination coins, leading to prolonged preparation times or incomplete change funds.
Innovation Solution
A money handling apparatus with separate storage units and a control unit that efficiently sorts and stores coins by denomination, ensuring the second storage unit always has the minimum required coins for change, and adjusts operation modes to prioritize replenishing shortage denominations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If coins of multiple denominations are stored in a mixed state in a single storage unit, then the storage space is efficiently utilized, but the time required to prepare change fund increases significantly
Solution Approach 1:
The storage unit is divided into multiple sub-storage units, each dedicated to storing coins of a specific denomination. This segmentation allows the system to maintain compact storage while enabling rapid retrieval of change fund coins without searching through mixed denominations, thus resolving the contradiction between space efficiency and preparation time.
Solution Approach 2:
Coins are pre-sorted by denomination and stored in respective sub-storage units before change fund preparation is needed. This preliminary organization eliminates the need for on-demand sorting, significantly reducing the time required to assemble change funds while maintaining efficient use of storage space.
2Reliability
If the coin handling apparatus repeatedly identifies and returns coins to the storage unit during change fund preparation, then the correct denominations are selected, but the preparation process becomes excessively time-consuming
Solution Approach 1:
Coins are pre-sorted and stored in sub-storage units according to their denominations before change fund preparation begins. This preliminary arrangement ensures that the correct coins are immediately available when needed, eliminating the time-consuming iterative process of identifying and returning coins while maintaining accurate change fund composition.
Solution Approach 2:
The sub-storage units act as intermediaries between the coin input and the change fund assembly process. They pre-organize coins by denomination, serving as a mediator that enables rapid and accurate selection of change fund coins without requiring repeated identification and return operations.
3Measurement precision
If coins are fed out one by one from the storage unit for recognition and sorting, then accurate denomination identification is achieved, but the overall processing speed decreases
Solution Approach 1:
Coins are pre-sorted by denomination and stored in respective sub-storage units before processing begins. This preliminary organization allows the system to maintain accurate denomination identification while significantly increasing processing speed, as coins are already organized and ready for rapid retrieval rather than requiring on-demand identification and sorting.

AI summary
A money handling apparatus includes: a first storage unit and a second storage unit; a transport unit; a recognition unit; and a control unit configured to transport the money in the first storage unit by the transport unit, recognize the money by the recognition unit, transport a part of the money from the first storage unit to the second storage unit based on a result of recognition to store money of predetermined denominations, for which a quantity of money of each denomination is set in advance, in the second storage unit. The control unit detects a shortage denomination of money in the first storage unit, and stores money of the shortage denomination larger in quantity than the quantity set in advance for the shortage denomination, into the second storage unit.
