Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional anti-ballistic barriers fail to effectively absorb the kinetic energy of projectiles such as vehicles, rockets, and personnel, leading to potential penetration and damage, and are often heavy and difficult to deploy quickly.
Innovation Solution
A deployable barrier system using flexible anti-ballistic materials formed into laminates, which can flex and move upon impact to absorb kinetic energy, and is secured with a mounting structure and deployment mechanism to protect spaces from kinetic objects, allowing for quick deployment and enhanced protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If heavy rigid materials are used for anti-ballistic barriers, then strength and penetration resistance are improved, but weight increases and deployment speed decreases
Solution Approach 1:
The patent uses flexible anti-ballistic materials formed into laminates that can flex and move upon impact. These flexible materials provide penetration resistance without requiring heavy rigid structures, directly resolving the contradiction between strength and weight.
Solution Approach 2:
The barrier is designed to be free to flex and move when struck, transforming from a static rigid structure to a dynamic flexible system. This dynamic behavior allows the barrier to absorb kinetic energy through movement while maintaining protection capability with reduced weight.
2Strength
If heavy rigid materials are used for anti-ballistic barriers, then strength and penetration resistance are improved, but deployment speed decreases
Solution Approach 1:
The flexible nature of the barrier allows for rapid deployment as it can be quickly positioned and secured without requiring heavy lifting or complex assembly of rigid components. The flexibility enables fast installation while maintaining protective strength.
3Strength
If conventional rigid barriers are used, then structural strength is improved, but kinetic energy absorption capability worsens
Solution Approach 1:
The barrier transitions from a rigid static structure to a flexible dynamic system that can move and deform upon impact. This dynamic response allows the barrier to absorb kinetic energy through flexing and movement rather than simply transmitting it, improving energy absorption capability while maintaining structural integrity.
Solution Approach 2:
The patent changes the physical parameters of the barrier material from rigid to flexible, allowing it to undergo deformation and movement. This parameter change enables the material to absorb kinetic energy through elastic deformation and dynamic movement, converting kinetic energy into other forms of energy.
4Weight of moving object
If lightweight materials are used for barriers, then weight and deployability are improved, but strength and penetration resistance worsen
Solution Approach 1:
The patent employs flexible anti-ballistic materials formed into laminates that provide penetration resistance despite their lightweight nature. These flexible materials achieve protective strength without requiring heavy construction, resolving the contradiction between weight and strength.
Solution Approach 2:
The barrier uses laminated composite structures formed from flexible anti-ballistic materials. The lamination creates a composite material system that achieves enhanced strength and penetration resistance through the layered structure, maintaining lightweight properties while improving protective capability.

AI summary
An kinetic object protection system for protecting a space in a building or vehicle comprising a protective barrier including one or more sheets of a laminated material having a plurality of layers of lightweight, flexible, ballistic resistant material such as woven sheets, nets, or mesh which are secured together using a glue, heat weld, or stitching. The system may include an automated control system operably configured to cause a change in state of the barrier from a retracted state to a protective deployed state, which may include a sensing system operably configured to detect a threatening event, wherein the sensing system upon sensing the threatening event triggers the barrier to transition from the retracted state to the deployed protective state such that in the protective state, the barriers are adapted to be resistant to penetration by the kinetic objects such as vehicles.
