Terminal Breach Protection With Gap Barriers and Shock Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Self-Service Terminals (SSTs) such as ATMs and SSCOs are vulnerable to attacks involving hook or chain mechanisms that apply sudden, sharp pulling forces to deform safe doors, allowing unauthorized access to stored currency.
Innovation Solution
Implementing penetration prevention devices (PPDs) to close gaps between terminal devices and safe doors, and shock-absorbing baseplates to mitigate breaching attempts by reducing peak forces and restricting movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If gaps exist between terminal devices and safe doors, then device access and assembly are easier, but foreign objects can be inserted to enable breaching
Solution Approach 1:
The penetration prevention device is divided into multiple segments that can be independently installed on different devices. Each segment includes a first portion attaching to the device and a second portion filling gaps, allowing modular deployment without requiring complete system replacement.
Solution Approach 2:
The penetration prevention device acts as an intermediary element between the terminal device and the safe door. It fills the gaps and provides a barrier that prevents foreign objects from directly contacting the safe door, while still allowing the device to function normally.
2Object-affected harmful factors
If shock-absorbing baseplate is added, then breaching force is reduced, but device complexity increases
Solution Approach 1:
The baseplate incorporates shock-absorbing elements that are pre-installed to cushion and absorb breaching forces before they can reach the safe door. This beforehand cushioning mechanism reduces the peak forces applied during breaching attempts without requiring complex active control systems.
Solution Approach 2:
The baseplate changes the mechanical parameters of the terminal structure by adding shock-absorbing materials and movement-restricting mechanisms. These parameter changes allow the terminal to withstand breaching forces while maintaining structural integrity, without significantly increasing overall complexity.
3Object-affected harmful factors
If penetration prevention device fills all gaps, then foreign object insertion is prevented, but device assembly becomes more difficult
Solution Approach 1:
The penetration prevention device is segmented into multiple independent portions that can be assembled separately. The first portion attaches to the device and the second portion fills the gaps, allowing for simplified assembly procedures while maintaining comprehensive gap coverage.
Solution Approach 2:
The penetration prevention device incorporates flexible and movable portions that can adapt to different gap sizes and device configurations. This dynamic capability allows the device to be easily assembled and adjusted without requiring precise pre-positioning or complex alignment procedures.
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
Prevents insertion of foreign objects and absorbs sudden forces, significantly reducing the likelihood of successful terminal breaching and protecting the safe contents.
Implementation Method 1
A movement restricting device, such as one or more springs, dampen the force by absorbing at least a portion of the energy
Implementation Method 2
The top and bottom plates are allowed to slide in a direction from which a breach-attempting force is likely to come with the sliding dampened by a movement restricting device

AI summary
Various embodiments herein each include at least one of devices, methods, and assemblies for terminal breach protection. Some such embodiments may be deployed to prevent insertion of implements, such as hooks and wedges, within a terminal, such as an ATM or SSCO, that may be used to apply sudden, sharp pulling forces to safe doors to enable access to currency stored therein. Some such embodiments also or alternatively include baseplates that at least partially absorb such sudden, sharp pulling forces in a direction from which they are applied in such terminal breaching attempts.
