V-Profile Defense Structure with Directional Projectile Permeability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ballistic resistant structures are ineffective in allowing defenders to exit or counterattack while maintaining protection, as they prevent projectiles from passing through and become a captive environment, lacking comprehensive room-level protection and enabling external defense capabilities.
Innovation Solution
The development of a V-profile defense structure with V-shaped wedges arranged in a column or row configuration, using fiberglass or polymer materials that absorb or deflect projectiles from one side while allowing them to pass through from the opposite side, featuring self-healing properties and flexible design to accommodate subsequent projectiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional ballistic resistant materials (concrete, high density fiberglass) are used to prevent projectiles from passing through, then protection capability is improved, but defenders cannot exit or counterattack and become captive
Solution Approach 1:
The defense structure uses different materials with different properties on each side: the exterior side uses flexible, projectile-yielding materials (fiberglass, polymer, viscous material) that allow projectiles to pass through, while the interior side uses rigid, projectile-stopping materials (concrete, steel) that prevent penetration. This local differentiation of material properties resolves the contradiction by making the structure selectively permeable to projectiles based on direction.
2Reliability
If safe rooms are located in remote locations to provide protection, then safety is improved, but defenders must travel through vulnerable areas to reach them
Solution Approach 1:
The ballistic resistant panels can be installed in various locations throughout a building or home, not just in a single remote safe room. Each panel independently provides protection, allowing defenders to take cover at multiple distributed locations rather than traveling to one centralized safe room, thereby reducing travel time and vulnerability exposure.
3Reliability
If massive concrete or high density fiberglass panels are used to block projectiles, then ballistic resistance is improved, but the structure becomes extremely costly and complex
Solution Approach 1:
The defense structure is divided into multiple independent panels, each containing a layered arrangement of ballistic resistant materials. This segmentation allows for modular construction and installation, reducing overall complexity compared to a single massive structure while maintaining equivalent protection levels through distributed defense points.
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
Enables defenders to proactively engage or disengage with assailants by allowing projectile passage from one side while maintaining resistance on the other, enhancing safety and tactical flexibility within secure environments and vehicles.
Implementation Method 1
The V-shaped wedges yield to the force of the projectile as it impacts the V-profile
Implementation Method 2
the defense structure absorbs a portion of or the entire projectile
Implementation Method 3
the defense structure deflects the projectile entirely
Implementation Method 4
the defense structure is partially self-healing when projectiles impact and enter the defense structure from the V-profile side and exit via the fiberglass side

AI summary
A ballistic resistant material and structure and methods for allowing and preventing projectiles from passing through the ballistic resistant defense structure. The ballistic resistant defense structure involves a ballistic multilayer arrangement comprised of V-Profiles 100 which are further comprised of V-shaped wedges arranged adjacent to each other, spaced slightly apart, with gaps. The gaps between the V-shaped wedges expand or contract depending on which side of the V-Profile a projectile strikes.
