Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current anti-ballistic protection systems in residential and commercial applications are either excessively heavy due to metal components or weak and flimsy when made of plastic, failing to effectively absorb the energy from ballistic projectiles and provide adequate protection.
Innovation Solution
A deployable barrier system using a flexible anti-ballistic material formed into a sheet, which can flex and move in response to impact, absorbing energy and featuring a deployment mechanism that transitions from a retracted to a deployed position to protect against ballistic objects, along with a control and sensing system to automatically activate protection modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metal plates are used in anti-ballistic protection systems, then ballistic protection capability is improved, but weight becomes excessively high
Solution Approach 1:
The patent employs composite materials consisting of multiple layers including Kevlar fabric, polyethylene terephthalate, and other high-strength polymers to achieve ballistic protection without the excessive weight of metal plates. The composite structure combines materials with different properties to optimize both protection capability and weight reduction.
Solution Approach 2:
The patent changes the material parameters from traditional metal to advanced polymers and composites, altering the density and strength-to-weight ratio. This parameter change enables achieving the same ballistic protection level with significantly reduced weight by using materials like ultrahigh molecular weight polyethylene and aramid fibers.
2Weight of moving object
If plastic materials are used to reduce weight, then weight is reduced, but the material becomes weak and flimsy providing no protection
Solution Approach 1:
The patent uses composite materials that combine multiple plastic and polymer layers with different functions. The composite structure includes load-bearing layers, energy-absorbing layers, and reinforcement layers, transforming weak individual plastic materials into a strong protective system.
Solution Approach 2:
The protective barrier is segmented into multiple functional layers, each designed to perform specific tasks in the ballistic protection process. This segmentation allows each layer to be optimized for its specific function while collectively providing comprehensive protection.
3Strength
If rigid barriers are used to stop projectiles, then ballistic protection is provided, but the barrier cannot absorb kinetic energy effectively
Solution Approach 1:
The patent incorporates dynamic elements that allow the barrier to move and deform in response to projectile impact. The flexible composite structure can dynamically absorb and dissipate kinetic energy through controlled deformation, rather than rigidly resisting the impact.
Solution Approach 2:
The multi-layer composite structure is designed beforehand to cushion and absorb impact energy. The layered construction includes materials specifically selected for their energy absorption characteristics, creating a cushioning effect that reduces the transmitted impact energy.

AI summary
A method of using an anti-ballistic protection system for protecting an interior space in a building. The ballistic barrier includes a laminated material having a plurality of layers of lightweight, flexible, ballistic resistant material such as woven sheets which are secured together into the laminate using a adhesive, heat weld, or stitching. The ballistic barrier in the deployed state is configured to be resistant to penetration by high-speed ballistic projectiles such as a bullet fired from a gun or a shrapnel from a bomb to protect the interior space, and can be used to protect windows, doors, hallways, and walls from penetration by the ballistic projectiles.
