Solution Overview

Problem

Conventional money handling apparatuses face inefficiencies in dispensing processes when coins are stored in mixed denominations, leading to potential delays and incomplete dispensing of required coins.

Innovation Solution

A money handling method that includes a dispensing process to efficiently manage mixed-denomination storage units by recording dispensing and depositing histories, adjusting denomination assignments, and performing replacement processes among storage units to optimize coin distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a storage unit stores a plurality of denominations of coins in a mixed state, then the apparatus can handle a larger number of denominations than the number of storage units, but the dispensing process becomes inefficient and time-consuming

Engineering Contradiction:

Improvenumber of denominations handledVSAvoiddispensing efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The system segments the storage units into different types: single-denomination storage units and mixed-denomination storage units. Each storage unit is assigned a specific role based on its denomination composition. This segmentation allows the system to efficiently manage multiple denominations while maintaining high dispensing speed by directing dispensing operations to appropriate storage units.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The control unit acts as an intermediary that manages the complex relationship between storage units and dispensing requirements. It records dispensing histories, analyzes coin availability, and dynamically determines the optimal dispensing strategy by coordinating between single-denomination and mixed-denomination storage units, thereby resolving the efficiency problem.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If coins are dispensed from a mixed-denomination storage unit, then the apparatus can dispense required denominations, but coins that are not to be dispensed may be fed out incorrectly

Engineering Contradiction:

Improvedispensing capabilityVSAvoidcoin identification accuracy

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system employs feedback mechanisms through coin recognition units that verify the denomination of each coin being dispensed. The control unit receives feedback on coin identification results and adjusts the dispensing process accordingly, ensuring that only the required denominations are dispensed even from mixed-denomination storage units, thereby maintaining high reliability.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

Before dispensing, the control unit performs preliminary analysis of the dispensing history and current coin availability in each storage unit. It pre-determines the optimal dispensing plan that avoids feeding out incorrect coins, and prepares the system by selecting appropriate storage units and dispensing sequences in advance.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If the apparatus waits for all required coins to be prepared in a temporary storage unit, then complete dispensing can be ensured, but customer wait time increases

Engineering Contradiction:

Improvedispensing completenessVSAvoidcustomer wait time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs partial preparation by pre-positioning frequently needed denominations in single-denomination storage units based on historical data, while allowing immediate dispensing from mixed-denomination units for less frequent denominations. This partial preparation approach ensures completeness for critical denominations without requiring full preparation of all coins, thereby reducing customer wait time while maintaining reliability.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The control unit dynamically adjusts the dispensing strategy based on real-time conditions including coin availability, dispensing history, and current transaction requirements. It can switch between different dispensing modes (immediate dispensing from mixed units vs. prepared dispensing from single-denomination units) to optimize the balance between completeness and speed.

Inventive Principle:

Principle #15Dynamics

AI summary

To improve efficiency of a dispensing process, a money handling method performed by an apparatus that feeds out money from storage units including a first storage unit storing denominations of money in a mixed state, and dispenses the money, include: performing a dispensing process for dispensing money corresponding to a dispensing amount to be dispensed; recording a dispensing history including information on the denominations and the quantity for each denomination of the money dispensed in the dispensing process; changing, based on the dispensing history, a denomination assignment to assign a first denomination assigned to the first storage unit to another storage unit among the storage units; and performing a replacement process for transferring money of the first denomination from the first storage unit to the other storage unit, for which the assigned denominations are changed.
