Solution Overview

Problem

Existing methods for marking or destroying valuable objects, such as banknotes, face challenges in achieving efficient liquid flow and space optimization while being adaptable to different directions and sizes, especially when protected by alarms.

Innovation Solution

A device comprising a compressible liquid container and a flattened, expandable gas generating container that inflates upon an alarm signal, forcing the liquid out efficiently and preventing backflow, allowing for rapid and effective marking or destruction, with adaptable size and direction capabilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a liquid container is used for marking or destruction, then the marking/colouration/destruction effect is achieved, but the liquid flow speed and efficiency are insufficient

Engineering Contradiction:
Improveliquid flow speedVSAvoidmarking efficiency
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The container is pre-compressed before activation, storing elastic potential energy that is rapidly converted to kinetic energy when released, propelling the liquid at high speed toward the target for immediate marking or destruction effect

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Gas is introduced into the container to create pressure differential, forcing the liquid to flow rapidly through the nozzle. The pneumatic pressure ensures high-speed liquid projection and complete coverage of the target object

Inventive Principle:
Principle #29Pneumatics and hydraulics

2Volume of moving object

If the device size is reduced for space economy, then space efficiency is improved, but the liquid distribution coverage and directionality are limited

Engineering Contradiction:
Improvedevice sizeVSAvoiddirection of work
Core Design Contradiction:
Volume of moving objectVSAdaptability or versatility

Solution Approach 1:

The device incorporates multiple nozzles arranged in different orientations, allowing the liquid to be distributed in multiple directions simultaneously. This segmentation of the ejection system enables comprehensive coverage of the target object without increasing overall device volume

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The container is designed to expand in three dimensions when gas is introduced, creating pressure from all directions to propel liquid through multiple nozzles. This dimensional expansion allows the compact device to achieve omnidirectional liquid distribution

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Speed

If the container is made compressible for rapid liquid release, then the liquid flow speed increases, but the control precision and timing are compromised

Engineering Contradiction:
Improveliquid flow speedVSAvoidcontrol precision
Core Design Contradiction:
SpeedVSEase of operation

Solution Approach 1:

The container is equipped with self-sealing valves and automatic pressure regulation mechanisms that maintain liquid containment until activation. Upon receiving the alarm signal, the system automatically releases the pre-compressed state, propelling the liquid without requiring manual intervention for timing or pressure control

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The device incorporates pressure sensors and flow meters that monitor the compression state and liquid flow in real-time. This feedback mechanism allows precise control of the release timing and liquid projection speed, ensuring accurate marking or destruction while maintaining high velocity

Inventive Principle:
Principle #23Feedback

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The solution enables fast, efficient, and space-efficient marking or destruction of valuable objects, with the inflatable container maintaining its state for extended periods, ensuring effective liquid distribution and minimizing device size while accommodating various orientations and security measures.

Implementation Method 1

Inside the flattened container 40, there is arranged a gas generating means 41. The gas generating means communicates with the alarm device, in order to be activated at the presence of an alarm signal, when the gas generating means produces a balloon-like inflation or expansion of the container 40.

AI summary

The invention relates to a method for marking or colouration or destruction of objects of value (100), such as banknotes, where at least one liquid medium (31) is used, which is contained in at least one compressible and openable container (30). At least one flattened and expandable container (40) is used in order to, when needed, compress the compressible container (30) in order to distribute the liquid medium (31) on the objects of value (100). At least one gas generating means (41) is placed inside the expandable container (40), in order to, in case of an alarm signal, expand the container (40). The liquid-containing container (30) is punctured or is opened at an alarm signal, at which time the expansion of the gas container (40) creates a liquid distribution over the objects of value (100). The invention also comprises a device for implementation of the method.
