ATM Security Cassette Ink Rupture Layout for Explosion Marking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security container cassettes for banknotes and values are ineffective in marking banknotes during burglaries involving explosives, especially when using limited quantities or specific types of explosives, as the marking systems fail to activate or are damaged inappropriately.
Innovation Solution
A security container cassette design with first and second containers, where the second container is pliable and ruptures upon explosion, distributing marking fluid directly onto banknotes, and includes weakened portions to facilitate immediate fluid release without sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pliable tank with marking ink is positioned above the banknotes, then the marking system activates upon explosion, but the tank may not break with limited quantities or specific types of explosives
Solution Approach 1:
The marking system is divided into multiple independent marking elements distributed across different locations within the container. Each element contains marking fluid and can independently activate upon explosion, ensuring that if one element fails to activate, others may still succeed. This segmentation increases overall reliability without requiring a single large tank that must break completely.
Solution Approach 2:
Different portions of the container are equipped with marking elements having different properties - some with more sensitive activation mechanisms, others with greater fluid volume. The distribution of marking elements varies by location, with certain areas having enhanced marking capability. This local differentiation ensures effective marking regardless of where the explosion occurs or what type of explosive is used.
2Ease of operation
If a pliable tank with marking ink is used, then automatic marking occurs upon bursting, but the tank may break in places where there are no banknotes
Solution Approach 1:
The marking system uses multiple small marking elements instead of one large tank. Each element contains a limited amount of marking fluid sufficient for its local area. When an explosion occurs, only the elements in or near the explosion zone activate and release their fluid, while elements in other areas remain intact. This prevents wastage of marking fluid in areas where no banknotes are present.
Solution Approach 2:
Each marking element is tailored to its specific location and the expected banknote density in that area. Elements are positioned and sized to mark only the relevant local area, ensuring that marking fluid is released only where needed. This localized approach minimizes fluid waste while maintaining effective marking coverage.
3Extent of automation
If active marking systems with sensors are used, then marking can be controlled, but the system creates significant shock waves that can eject banknotes during explosion
Solution Approach 1:
The marking system requires no external sensors, power sources, or control mechanisms. The marking elements are designed to activate automatically through passive mechanical response to explosion pressure - the pressure simply causes the element to break and release its fluid. This self-service approach eliminates the need for electronic components that would add complexity and potential failure points, while the passive activation mechanism generates minimal additional shock waves.
Solution Approach 2:
The marking elements are designed as simple, inexpensive, single-use components with no moving parts or electronic components. Each element is a straightforward container-marking fluid assembly that breaks irreversibly upon activation. This simplicity reduces the overall complexity of the system and eliminates the need for sensors, batteries, or control circuits that would contribute to shock wave generation.
