Safe Segmentation Plate for Explosive Attack Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Self-service terminal safes, such as those in ATMs, face challenges due to large apertures that allow access for thieves, and are vulnerable to prying and explosive attacks, which can compromise the security of high-value currency cassettes.
Innovation Solution
The safe incorporates a segmentation plate that divides the internal volume into compartments, with relief portions and movable side rails to absorb explosive energy and engage additional locking mechanisms, and a reinforcement member to link exterior walls, enhancing fortification and resistance to pressure increases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If large apertures are provided in the safe for currency transport during transactions, then operational functionality is improved, but security against theft and explosive attacks deteriorates
Solution Approach 1:
The safe is divided into multiple compartments by segmentation plates that can move between locked and unlocked positions. When locked, the segmentation plates block access to currency cassettes even if the door is opened, effectively segmenting the interior space to prevent thief access while maintaining large external apertures for legitimate currency transport operations
2Strength
If the safe structure is reinforced to resist explosive attacks, then security against explosive attacks is improved, but the safe's vulnerability to explosive pressure increases without proper pressure relief
Solution Approach 1:
The segmentation plates are designed to move in response to explosive pressure, converting the harmful explosive force into a useful locking action. When explosive pressure is detected, the segmentation plates automatically shift to locked positions, using the explosive energy itself to trigger the security response and close off compartments to protect remaining currency
3Reliability
If segmentation plates are made movable to enable pressure-responsive locking, then security response to explosive attacks is improved, but device complexity increases
Solution Approach 1:
The segmentation plates are designed to automatically move and lock in response to explosive pressure without requiring external control systems, sensors, or power sources. The mechanism uses the explosive pressure itself as the actuating force, eliminating the need for complex electronic controls, batteries, or external monitoring systems while maintaining reliable security response

AI summary
A safe may include a body. The body may include a first sidewall, a second sidewall, a top, a bottom, a rear sidewall and a door that may define an interior volume. The door may be hingably connected to the second sidewall. The safe may also include a first side channel and a second side channel. The first side channel may be attached to the first sidewall and the second side channel may be attached to the second sidewall. The safe may also include a segmentation plate that may include a first vertical side rail and a second vertical side rail. The first vertical side rail may be slideably located in the first side channel and the second vertical side rail may be slideably located in the second side channel.
