Deployable Anti-Ballistic Barrier for Kinetic Energy Dissipation
Solution Overview
Problem
Conventional anti-ballistic barriers fail to effectively absorb kinetic energy from projectiles like vehicles, rockets, and personnel, often transmitting energy and allowing penetration due to their rigidity and heaviness, and are typically fixed, making them difficult to deploy quickly and mobilize.
Innovation Solution
A mobile barrier system utilizing flexible anti-ballistic materials formed into laminates that can be retracted and deployed, allowing the barrier to flex and absorb kinetic energy by moving in response to impacts, with a deployment mechanism to secure it in place and protect against kinetic objects of substantial mass.
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 mobility and deployment speed deteriorate
Solution Approach 1:
The barrier transitions from a static, fixed structure to a dynamic, mobile system. The flexible laminate can be deployed and retracted on demand, allowing rapid response to threats while maintaining protective strength when deployed.
Solution Approach 2:
The patent uses flexible anti-ballistic laminate materials instead of heavy rigid blocks. This flexible film approach provides the necessary strength to stop projectiles while being lightweight enough for rapid deployment and mobility.
2Strength
If rigid barriers are used, then penetration resistance is improved, but kinetic energy absorption deteriorates
Solution Approach 1:
The barrier's physical state changes from rigid to flexible upon deployment. This parameter change allows the material to deform and absorb kinetic energy through elastic deformation, converting the projectile's energy into work done on the barrier material itself.
Solution Approach 2:
The flexible laminate undergoes elastic deformation (a form of phase transition) when struck by a projectile, transitioning from its equilibrium state to a deformed state that absorbs energy, then returning to its original state. This cyclic deformation effectively absorbs and dissipates kinetic energy.
3Reliability
If fixed barriers are installed, then protection reliability is improved, but adaptability and mobility deteriorate
Solution Approach 1:
The system provides reliable protection when deployed through its flexible laminate design, yet maintains full mobility when retracted. The dynamic nature of the barrier allows it to be stationary during threats (providing reliability) and mobile during normal operation (providing adaptability).
Solution Approach 2:
The mobile barrier system serves multiple functions: it provides fixed-like protection when deployed, maintains mobility when retracted, and can be positioned anywhere needed. This multi-functionality resolves the contradiction between reliability and adaptability.
