Ballistic Security Barrier Wall-Mounted Frame Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a rapid and cost-effective way to secure entryways in public facilities against unauthorized access without modifying existing door structures, while ensuring compliance with fire safety standards and not compromising occupant safety.
Innovation Solution
A stand-alone, single-layer ballistic security barrier system that can be installed over existing doors, using structural steel, ballistic armor, and a magnetic or mechanical/electrical locking system, allowing for easy activation and deactivation to create a secure 'safe room' without interfering with the existing door mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a ballistic security barrier is installed to protect against firearms, then protection effectiveness is improved, but installation complexity and cost increase
Solution Approach 1:
The barrier system is divided into separate components: a wall-mounted frame structure and a door-mounted ballistic barrier panel. This segmentation allows the barrier to be installed independently of the door structure, simplifying installation while maintaining protection effectiveness against firearms and high-powered rifles.
Solution Approach 2:
The patent introduces a wall-mounted frame as an intermediary structure between the building wall and the door. This frame serves as the anchor point for the ballistic barrier, eliminating the need to modify the door structure itself and reducing installation complexity while ensuring reliable protection.
2Reliability
If the barrier is secured to prevent unauthorized entry, then security is improved, but ease of exit in emergencies deteriorates
Solution Approach 1:
The barrier incorporates a dynamic locking mechanism that can be securely locked during normal operation to prevent unauthorized entry, but can be quickly unlocked and opened with a single motion from the inside during emergencies. This dynamic capability allows the system to adapt between security and emergency egress modes.
Solution Approach 2:
The patent extracts the locking function from the door itself and places it on the barrier panel. The barrier can be independently locked to secure the entryway, while the door retains its original functionality for normal use and emergency egress, separating the security function from the egress function.
3Area of stationary object
If the barrier is mounted close to the door to save space, then area utilization is improved, but interference with door operation increases
Solution Approach 1:
The barrier system transitions from a two-dimensional door-mounted approach to a three-dimensional wall-mounted configuration. By mounting the barrier on the wall in front of the door rather than directly on the door, the system achieves compact space utilization while maintaining sufficient clearance for door operation and handle functionality.
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
The system provides effective protection against firearms and high-powered rifles while allowing for easy operation during normal use and compliance with fire safety standards, enabling quick lockdown and exit in emergency situations.
Implementation Method 1
The barrier may be selectably secured with a magnetic lock or with suitable mechanical and/or electrical technology

AI summary
A stand-alone, single-layer, auxiliary ballistic security barrier system configured to be installed over existing doors. The ballistic security barrier system provides protection against an active shooter with weapons, including handguns and high-powered rifles. The ballistic security barrier system includes a frame fixed to a wall with an anchor system and having structural tubing, mounting angle, and a locking system located inside the structural tubing. Further, the system includes a barrier pivotably attached to the frame and made out of material suitable to withstand impact from a high velocity rifle. The barrier is held in a first stowed position by a release apparatus, and in a second closed position by a lock.
