Coin Storage Apparatus Replenishment Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coin handling apparatuses require repetitive coin dispensing and recognition processes to store coins of specific denominations, making efficient storage of a specific denomination challenging.
Innovation Solution
A coin storage method and apparatus that involve letting out coins from a first storage unit, recognizing their denomination, and executing a replenishment operation to store them in a second storage unit until a predetermined denomination/number-of-coins combination is achieved, allowing for efficient storage and retrieval of coins based on pre-set patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If coins are stored in a storing unit with a predetermined number for each denomination, then change can be dispensed promptly, but the system requires repetitive dispensing and recognition processes to maintain the storage
Solution Approach 1:
The system performs preliminary action by pre-storing coins of multiple denominations in the storing unit before change dispensing is needed. This allows the system to have coins ready in advance, eliminating the need for repetitive dispensing and recognition processes when change is required, thus resolving the contradiction between fast dispensing and time-consuming maintenance operations.
2Productivity
If coins are selectively stored based on denomination recognition, then efficient storage of specific denominations is achieved, but the device complexity increases due to additional recognition and control mechanisms
Solution Approach 1:
The storing unit is designed to serve multiple functions: it stores coins of different denominations, acts as a recognition target for denomination identification, and functions as a controlled dispensing mechanism. By making the storing unit multi-functional, the system achieves efficient selective storage without requiring separate dedicated components for each function, thus improving productivity while limiting the increase in device complexity.
3Reliability
If a predetermined number of coins for each denomination is maintained in storage, then change dispensing is prompt, but the system requires continuous monitoring and replenishment operations
Solution Approach 1:
The system implements feedback by continuously monitoring the number of coins of each denomination in the storing unit and automatically triggering replenishment operations when thresholds are reached. This feedback mechanism ensures reliable change dispensing by maintaining predetermined coin levels while automating the replenishment process, thus improving reliability without significantly complicating operation through centralized control logic.

AI summary
Provided is a coin storage method that is executed by a processor of a coin storage apparatus. The coin storage method includes: letting out a coin from a first storage unit, which is configured to store a plurality of coins of a plurality of denominations; recognizing a denomination of the coin that has been let out; and executing, based on a number of coins for each denomination having been already stored in a second storage unit and the denomination of the recognized coin, a replenishment operation in which the recognized coin is selectively stored in the second storage unit, wherein the second storage unit is configured to store a coin to be withdrawn outside; wherein the executing of the replenishment operation further comprises changing, depending on the denomination of the coin let out from the first storage unit, a denomination/number-of-coins combination of one or a plurality of coins to be stored in the second storage unit in the replenishment operation.
