Banknote Container Security Device Combustion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security devices for banknote containers, such as ATMs and Bancomats, are inadequate in preventing explosions caused by the introduction of explosive substances through minimal slots, as they do not effectively combust these substances before they reach a critical mass.
Innovation Solution
A security device with ignition means inside the container to combust explosive substances and conveying means to forcibly convey the atmosphere to the ignition means, ensuring substances are ignited before reaching a critical mass, using a sinusoidal flow rate to achieve a stoichiometric ratio for ignition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If explosive substances are introduced through minimal slots, then the container can be opened from the inside, but the security of the container is compromised
Solution Approach 1:
The ignition means are positioned inside the container to preemptively ignite explosive substances before they can accumulate to a critical mass. The conveying means continuously draw air through the container, ensuring that any introduced explosive substance is immediately carried to the ignition means for combustion, preventing the substance from reaching a dangerous accumulation level
Solution Approach 2:
The system converts the potentially harmful explosive substance into a beneficial protective mechanism by using the conveying means to direct the explosive substance to the ignition means, where it is combusted in a controlled manner. This transforms the threat of explosion into a preventive combustion that occurs before critical mass is reached
2Object-affected harmful factors
If CO2 or aerosols are discharged to inhibit flames, then fire can be suppressed, but the device complexity increases
Solution Approach 1:
The invention extracts the core protective function from complex flame suppression systems and simplifies it to a direct ignition approach. Instead of using multiple components for CO2 discharge, aerosol generation, and flame detection, the system uses a straightforward configuration where conveying means deliver air directly to ignition means, which combusts explosive substances before they can cause harm
Solution Approach 2:
The patent replaces complex mechanical flame suppression systems with a simpler thermal combustion approach. Rather than mechanically discharging CO2 or aerosols to suppress flames, the system uses thermal energy from the ignition means to combust explosive substances in advance, eliminating the need for complex suppression mechanisms
3Object-affected harmful factors
If mechanical devices are used to hinder access of detonating gases, then explosion risk is reduced, but the ease of operation decreases
Solution Approach 1:
The conveying means act as an intermediary system that allows functional slots to remain open for normal operations while simultaneously protecting against explosive substance introduction. The conveying means continuously draw air through the container, ensuring that any explosive substance introduced through open slots is immediately carried to the ignition means for combustion, thus mediating between operational accessibility and security protection
