Ballistic Shield With Integrated Door Breaching Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ballistic shields for law enforcement personnel lack integrated door-breaching capabilities and fail to provide adequate ballistic protection during the most dangerous phase of door breaching operations, requiring multiple personnel and not being suitable for single-user operation.
Innovation Solution
A lightweight, portable ballistic shield with integrated door-prying wedges and a bulletproof glass observation window, designed for single-user operation, featuring a door-breaching assembly with opposing wedges connected by a bar and a handle system for easy carrying and operation, providing Level IV ballistic protection and allowing for breaching of doors with minimal destructive impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a shield is used for protection during door breaching, then ballistic protection is provided, but the shield lacks integrated door-breaching capabilities
Solution Approach 1:
The patent combines a ballistic shield with a door breaching assembly into a single integrated device. The breaching assembly includes a battering ram and prying wedges that are mounted on the shield body, allowing the same device to provide both ballistic protection and door breaching functionality. This merging eliminates the need for separate shield and breaching tool operations.
Solution Approach 2:
The shield is designed to perform multiple functions: it provides ballistic protection against gunshots and projectiles, enables door breaching through integrated ram and wedge mechanisms, and allows observation through a bulletproof window. This multi-functionality makes the device suitable for various law enforcement scenarios including protective shielding, door entry, and observation.
2Reliability
If separate shield and door breaking tools are used, then both protection and breaching functions are available, but at least two personnel are required for operation
Solution Approach 1:
The patent integrates the door breaching assembly directly onto the shield body, creating a unified device that can be operated by a single person. The battering ram and prying wedges are mounted in positions that allow the user to access and operate them while maintaining shield posture, eliminating the need for a second person to assist with breaching operations.
3Productivity
If a traditional Halligan tool is used for mechanical breaching, then quick and effective door entry is achieved, but ballistic protection is not provided
Solution Approach 1:
The patent merges the Halligan-like prying wedge functionality with a ballistic shield. The prying wedges are integrated into the shield body and can be used to insert into door cracks and defeat locking mechanisms, while the shield simultaneously provides ballistic protection against attacks from inside the building during the breaching operation.
4Reliability
If a shield without observation window is used, then protection is provided, but the user cannot clearly observe the breach site
Solution Approach 1:
The shield incorporates a bulletproof observation window in a specific location that allows the user to view the breach site and interior of the building through the shield. This local addition of transparent material with ballistic properties enables simultaneous protection and observation, allowing the user to monitor the situation while maintaining defensive posture.
