Cash Spoiling System with Segmented Adhesive Zones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cash spoiling systems for ATMs fail to ensure that all banknotes are rendered unusable and identifiable as authentic, as they either allow notes to be partially peeled or bonded into solid blocks, making it difficult to authenticate and replace individual notes.
Innovation Solution
A cash spoiling apparatus with a controlled adhesive dispensing system that uses a gas-activated piston to ensure uniform adhesive application along one side of the banknotes, allowing individual authentication while rendering the other side unusable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive is sprayed into the cassette over the notes in a nonuniform chaotic manner, then all notes are intended to be bonded together to render them useless, but individual notes cannot be subsequently separated for authentication and some notes may not be properly bonded
Solution Approach 1:
The adhesive application is segmented into two distinct zones: a first adhesive application zone that applies adhesive to a first portion of the banknotes, and a second adhesive application zone that applies adhesive to a second portion of the banknotes. This segmentation ensures that different areas of the banknotes receive controlled adhesive application, allowing both spoiling and authentication.
Solution Approach 2:
Different qualities of adhesive application are applied to different locations on the banknotes. The first adhesive application zone provides sufficient adhesive to render notes unusable, while the second adhesive application zone provides controlled adhesive that allows notes to be separated for authentication. This local differentiation resolves the contradiction between spoiling effectiveness and authentication capability.
2Reliability
If adhesive is sprayed in a nonuniform chaotic manner to ensure all notes are bonded, then notes are rendered unusable, but they cannot be individually identified by the responsible authority
Solution Approach 1:
The adhesive dispensing system is divided into multiple dispensers positioned at different locations, creating distinct adhesive application zones. This segmentation ensures that not all notes are uniformly bonded, leaving some areas accessible for identification while maintaining spoiling effectiveness in other areas.
Solution Approach 2:
The system applies adhesive partially to certain portions of the banknotes rather than uniformly across all notes. The first adhesive application zone applies sufficient adhesive for spoiling, while the second zone applies controlled adhesive that preserves identifiability, implementing partial action to resolve the contradiction.
3Reliability
If a solid block of banknotes is formed by adhesive bonding, then notes are rendered useless, but the system complexity increases and retrofitting becomes difficult
Solution Approach 1:
The adhesive dispensing system is designed to be integrated within the existing cassette structure of standard ATMs. The multiple dispensers and application zones are incorporated into the cassette's existing framework, allowing the system to serve multiple functions (spoiling, bonding, and identification) without requiring complete system replacement, thus reducing overall complexity.
Solution Approach 2:
The adhesive dispensing mechanism is nested within the existing cassette structure. The dispensers are positioned inside the cassette housing, utilizing the existing spatial framework. This nesting approach allows the complex adhesive application system to be integrated into the simple existing cassette design, minimizing overall system complexity while maintaining theft deterrence functionality.

AI summary
Ά system for spoiling banknotes arranged In a block formation within a container. The apparatus of the system comprises spoiling fluid contained within a receptacle located within the container. Also provided are means to release the fluid from the receptacle and means to direct said released fluid over and along one entire side of the block of banknotes. A manifold having at least one channel or groove provides directional means along which the spoiling fluid travels. The spoiling -fluid is dispersed from the manifold along an edge thereof onto the banknote's.
