Vestibule Metal Detection Array with Door Locking and Sleep Agent
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security devices fail to effectively detect and deter individuals carrying firearms from entering or leaving a building, posing a risk to the safety of occupants.
Innovation Solution
A vestibule with hinged bullet-resistant doors and a metal detection array that, upon detecting firearm components, locks the doors and releases a sleep agent to subdue the individual, ensuring the firearm is not brought into or taken out of the institution, while video cameras record the event for documentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If a metal detection array is used to detect firearms, then detection capability is improved, but false detection of non-firearm metal objects cannot be avoided
Solution Approach 1:
The metal detection array is divided into multiple sensor elements arranged in specific patterns, allowing the system to detect not only the presence of metal but also its spatial distribution and shape characteristics. This segmentation enables differentiation between firearm-shaped metal objects and other metal items through pattern recognition algorithms.
2Object-affected harmful factors
If doors are locked to prevent firearm entry, then security is improved, but legitimate access is blocked
Solution Approach 1:
The system performs preliminary detection of metal objects before triggering the door locking mechanism. The control unit analyzes detection data in real-time to determine whether a firearm is present, and only locks the door when a firearm is confirmed. This preliminary action allows legitimate access to continue while preventing firearm entry.
Solution Approach 2:
The system continuously monitors the detection array output and adjusts door locking status based on real-time feedback. When metal objects are detected, the control unit evaluates the detection pattern, and only activates the lock when firearm characteristics are confirmed. This feedback mechanism ensures that normal metal objects do not trigger false positives that would block legitimate access.
3Object-affected harmful factors
If a sleep agent is released to subdue the individual, then deterrence is improved, but safety risks from chemical exposure increase
Solution Approach 1:
The system applies preliminary non-lethal countermeasures through sleep agent release before physical confrontation occurs. The sleep agent serves as a preliminary anti-action that incapacitates the threat without requiring direct physical intervention, reducing the risk of injury to occupants and responders while effectively neutralizing the firearm threat.
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 solution effectively prevents firearms from entering or leaving a building, ensuring the safety of occupants by detaining the individual until authorities arrive, thereby protecting the institution from potential threats.
Implementation Method 1
A metal detection array is positioned within the vestibule to detect metal components of a firearm

AI summary
A building security assembly includes a vestibule that may be attached to an entrance of an institution and the vestibule has an entrance and an exit. A first door is hingedly coupled to the vestibule to open and close the entrance. A second door is hingedly coupled to the vestibule to open and close the exit. A metal detection array is positioned within the vestibule to detect metal components of a firearm. A security unit is coupled to the vestibule and is in electrical communication with the metal detection array. The security unit locks each of the first and second doors when the metal detection array detects the metal components of the firearm to inhibit the individual from bringing the firearm into the institution.
