Removable Bulletproof Shield with Distinct Alarm System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vulnerable facilities such as schools and churches lack effective protection against active shooters, with current bulletproof shields being too heavy for individuals to carry and law enforcement response often delayed, making existing solutions ineffective in preventing casualties during active shooter incidents.
Innovation Solution
A wall-mounted, removable bulletproof shield with a unique alarm system that can be quickly accessed by individuals, featuring a bullet-resistant design and a distinct alarm protocol to differentiate it from fire alarms, allowing for rapid recognition and response to active shooter situations, and an interconnected communication system to alert others.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional bulletproof shields are used, then protection against ballistic weaponry is provided, but the shields are too heavy for individuals to carry and require law enforcement training to operate
Solution Approach 1:
The shield system is divided into two main segments: a stationary wall-mounted base structure and a removable shield panel. The base contains mounting mechanisms and alarm systems, while the shield panel can be quickly detached and carried. This segmentation allows the heavy protective function to remain fixed while providing lightweight portable protection when needed.
Solution Approach 2:
The shield panels are pre-positioned and pre-mounted on walls throughout the facility before any threat occurs. This preliminary placement ensures immediate availability without requiring individuals to carry heavy shields or wait for law enforcement deployment. The shields are ready for instant grabs and use.
2Strength
If law enforcement deploys bulletproof shields to active shooter scenes, then protection is provided, but the response time is too delayed to prevent casualties
Solution Approach 1:
The shield panels are pre-positioned and pre-mounted on walls throughout the facility before any threat occurs. This preliminary placement ensures immediate availability without requiring individuals to carry heavy shields or wait for law enforcement deployment. The shields are ready for instant grabs and use.
Solution Approach 2:
The system enables individuals to protect themselves without requiring law enforcement intervention or specialized training. The shields are designed for easy removal and immediate use by any person in the facility, allowing self-protection during the critical minutes before first responders arrive.
3Loss of information
If standard alarm systems are used, then alerts are provided, but the alarms cannot be differentiated from fire alarms causing confusion
Solution Approach 1:
The alarm system uses distinctive acoustic patterns and temporal characteristics that differentiate active shooter alerts from fire alarms. The alarm emits a unique sound signature that is immediately recognizable as an active shooter warning, preventing confusion and enabling rapid appropriate response.
Solution Approach 2:
The alarm system employs specific temporal patterns and periodic signaling sequences that are distinct from standard fire alarm protocols. These unique periodic patterns enable immediate recognition of the threat type without requiring additional communication or causing panic from ambiguous alerts.
4Ease of operation
If shields are made removable and accessible, then quick access is enabled, but the shields must be securely mounted to prevent unauthorized removal
Solution Approach 1:
The mounting system features dynamic characteristics with quick-release mechanisms that provide strong secure mounting during normal conditions but allow rapid detachment when needed. The system transitions from a securely locked state to an easily removable state through simple user action, balancing security with accessibility.
Solution Approach 2:
The mounting mechanism acts as an intermediary between the shield panel and wall structure, providing secure attachment through mechanical locking while enabling quick release through a simple triggering action. This intermediary system resolves the contradiction between strong mounting and easy removal.

AI summary
A system and device for providing bullet proof protection to persons is described. A pre-staged shield, possibly wall mounted, that is capable of shielding the head and torso, for example, may be provided in a vulnerable facility. An optional and distinct alert system may be activated when the shield is removed from its location, whether seated on the wall, mount, or container such as a storage locker. Such alert system may be triggered by a switch, such as a pressure sensing seat in communication with a loudspeaker and alarm or monitoring system. When an alarm is activated, an optional distinct alert is sounded within the facility and the monitoring system may alert law enforcement and emergency first responders of the active shooter location. Such a shield and system may permit an unarmed, unprepared person to have the opportunity to shield themselves.
