Solution Overview

Problem

The existing coin handling apparatuses do not effectively prevent counterfeit coins and other rejected coins from re-entering circulation when ejected to the coin outlet.

Innovation Solution

A coin handling apparatus with an inlet section for customer-side coin deposition, a recognition unit to identify rejected coins, and a first ejection section on the attendant side for safely handling recognized rejected coins, including counterfeit ones, to prevent re-circulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If rejected coins are ejected to the coin outlet, then the coin handling apparatus can process rejected coins, but counterfeit coins may be put into circulation again

Engineering Contradiction:

Improverejected coin ejectionVSAvoidcounterfeit coin re-circulation

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The ejection function is segmented into two separate ejection sections: a first ejection section for counterfeit coins and a second ejection section for other rejected coins. This segmentation allows differentiated handling of rejected coins, preventing counterfeit coins from being mixed with valid coins in the coin outlet.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A temporary storage section is introduced as an intermediary between the recognition unit and the ejection sections. This temporary storage allows for additional verification and differentiation of rejected coins before ejection, ensuring that counterfeit coins are properly identified and directed to the appropriate ejection section.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If a first ejection section for counterfeit coins is added, then counterfeit coin security is improved, but device complexity increases

Engineering Contradiction:

Improvecounterfeit coin preventionVSAvoidejection section structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

Multiple ejection functions are merged into a unified ejection mechanism that can selectively direct different types of rejected coins to different ejection sections. The ejection mechanism integrates the functionality of handling both counterfeit coins and other rejected coins through a coordinated system of ejection sections and control unit.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The ejection mechanism is designed with multi-functionality, where the first and second ejection sections can be controlled to handle different types of rejected coins. The control unit provides universal control over the ejection process, allowing the system to adapt to different coin rejection scenarios without requiring entirely separate mechanisms.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A coin handling apparatus (1) comprises an inlet section (2) that is provided on customer side of the coin handling apparatus (1) and from which the coins are put in, a recognition unit (13) that recognizes the coins put in from the inlet section (2), and a first ejection section (20) that is provided on attendant side of the coin handling apparatus (1) and to which the coins recognized as rejected coins by the recognition unit (13) are ejected.
