Solution Overview

Problem

Conventional banknote processing systems pose security risks by concentrating cash in a single location during nighttime, making them vulnerable to theft and requiring cumbersome manual handling between front and backyard areas.

Innovation Solution

A banknote processing machine with a controller that enables a 'leaving mode' to disperse banknotes between multiple locations, using a cassette system with an ink spray unit to deter unauthorized access and a remote-controlled operation for enhanced security.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If banknotes are concentrated in a single location (money processing unit in backyard area), then security management is simplified, but the risk of theft increases and manual handling becomes necessary

Engineering Contradiction:

Improvesecurity management complexityVSAvoidsecurity against theft

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent divides the banknote storage function into multiple segmented locations: a front-area banknote processing machine with a cassette unit and a backyard money processing unit. Each location can independently store and manage banknotes, creating spatial segmentation that reduces vulnerability to single-point theft while distributing management complexity across multiple accessible locations.

Inventive Principle:

Principle #1Segmentation

2Reliability

If banknotes are dispersed across multiple locations, then security against theft is enhanced, but manual handling and operation complexity increases

Engineering Contradiction:

Improvesecurity against theftVSAvoidmanual handling burden

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The cassette unit in the front-area banknote processing machine is designed to automatically load and unload cassettes containing banknotes. The system self-manages the transfer of banknotes between the front and backyard areas without requiring manual intervention, thereby maintaining operational ease while achieving dispersed storage for enhanced security.

Inventive Principle:

Principle #25Self-service

3Ease of operation

If banknotes are left in the front area during nighttime, then manual handling is avoided, but security protection becomes insufficient

Engineering Contradiction:

Improvemanual handling avoidanceVSAvoidsecurity vulnerability

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The cassette unit acts as an intermediary mechanism between the front-area banknote processing machine and the backyard money processing unit. It automatically transfers banknotes to the secure backyard location during nighttime hours, providing security protection while avoiding manual handling. The cassette unit mediates the transfer process, ensuring banknotes are securely stored in the backyard area during vulnerable nighttime periods.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A controller 50 of a banknote processing machine 10 is configured to selectively perform a leaving mode, in which the banknote is fed out from each of the storing/feeding units 28, transported to the first cassette (recycle cassette 42) by the transport unit 24, and stored and left in the first cassette, when the first cassette is accommodated in the cassette accommodation unit 40.
