Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic cash machines are vulnerable to irreversible damage from attacks such as explosions, ramraiding, and vandalism, posing a significant financial burden on their owners.
Innovation Solution
A protective device comprising a metal cage with reinforced shutters and security systems, including multiple materials with different properties to resist impact, cutting, and explosions, and triggers security measures upon attack.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a single-material shutter is used to protect the cash machine, then the device complexity is low, but the resistance to various forms of attack (explosions, cutting, drilling) is insufficient
Solution Approach 1:
The shutter is constructed from multiple distinct materials (e.g., steel, ceramic, polymer) with different properties, where each material contributes specific protective characteristics such as resistance to cutting, drilling, or explosions. This composite structure enables the shutter to withstand various forms of attack more effectively than a single-material construction would allow.
2Strength
If reinforced shutters with multiple materials are installed, then the resistance to attack is improved, but the weight and cost of the protective device increase
Solution Approach 1:
Different materials are strategically positioned in specific regions of the shutter based on the type of attack expected in that area. For example, harder materials may be placed on the outer surface to resist cutting and drilling, while lighter materials are used in areas less susceptible to such attacks. This localized material distribution maintains protective effectiveness while reducing overall weight compared to using the heaviest material throughout.
3Reliability
If security systems are added to detect attacks on the shutter, then the reliability of protection is improved, but the device complexity increases
Solution Approach 1:
Security systems such as sensors, detectors, or monitoring devices are integrated into the protective structure to detect attempts at attack (e.g., drilling, cutting, or impact). These systems provide real-time feedback about the integrity of the shutter and can trigger alarms or notify authorities, thereby enhancing the overall reliability of the protection without requiring complex active defense mechanisms.

AI summary
A protective device for protecting an element that is to be made more secure includes: a cage forming a frame for bearing against a support surrounding the element that is to be secured, the cage including fixing and/or anchoring means for attaching the cage to the support; inside the cage, at least a first shutoff means for shutting off the element that is to be made more secure; and security systems to be triggered upon an attack made on the first shutoff means. The first shutoff means is reinforced with several distinct materials.
