Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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
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
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
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
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
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
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
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
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.
Implementation Method 2
The container 30 is made from a flexible material, such as plastic or metal foil, sheet metal or similar.

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.
