Modular Attack-Resistant Barrier with Polycarbonate Panes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional barriers lack attack resistance, particularly against vehicular, ballistic, and blast attacks, and are not easily deployable or adaptable for different locations.
Innovation Solution
The development of an attack-resistant barrier system incorporating attack-resistant panes made of materials like polycarbonate-reinforced glass, secured by framing pieces and armor strips, which can be retrofitted onto existing barriers, providing comprehensive ballistic and blast protection while allowing visibility and ease of movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional barriers are used, then ease of deployment is maintained, but attack resistance (ballistic and blast protection) is insufficient
Solution Approach 1:
The barrier is divided into modular components: a base barrier unit and separate attack-resistant pane assemblies. The panes are secured in framing pieces that can be attached to the barrier, allowing the system to be assembled in segments rather than as a single complex structure.
Solution Approach 2:
The barrier combines conventional barrier materials with attack-resistant pane materials (such as polycarbonate-reinforced glass or acrylic) to create a composite structure that provides both the structural function of the barrier and the ballistic/blast resistance of the specialized panes.
2Reliability
If attack-resistant panes are added to provide ballistic and blast protection, then protection capability is improved, but the barrier becomes less mobile and harder to reposition
Solution Approach 1:
The barrier system is designed to be dynamically reconfigurable. The attack-resistant panes are secured in framing pieces that can be attached and detached from the barrier, allowing the barrier to be repositioned or reconfigured as needed while maintaining protection when deployed.
3Reliability
If thick attack-resistant panes are used to ensure ballistic resistance, then protection level is improved, but visibility through the barrier is reduced
Solution Approach 1:
The patent specifies that the attack-resistant panes have a thickness of 1/8 inch to 1/2 inch, which provides ballistic resistance while maintaining optical transparency. This parameter range balances the competing requirements of protection and visibility.
4Reliability
If custom attack-resistant barriers are manufactured for each location, then optimal protection is achieved, but deployment time and cost increase
Solution Approach 1:
The barrier system uses universal, standardized components including the base barrier unit, framing pieces, and attack-resistant panes that can be deployed at multiple locations without custom manufacturing. The modular design allows rapid deployment while providing optimized protection through proper component selection and configuration.

AI summary
A barrier that includes attack resistant pane(s) (see DEFINITIONS section). In this way, a person behind the barrier can be protected when they are outside. More specifically, the person behind the barrier is protected, at least to some extent, from both: (i) vehicular attacks; and (ii) blast (for example, bombs) and/or ballistic (for example, bullet) attacks. Also, the protected person can see what is happening across the barrier because of the attack-resistant pane(s). Also, if the barrier is unanchored then it can be moved from place to place, for example, by heavy equipment, so that the same barrier can be re-deployed at different outdoor locations (or indoor locations) on an as-needed basis. Preferably, the barrier also includes framing pieces that secure the attack-resistant pane(s) to the body of the barrier, with the framing pieces being covered on one side by an attack-resistant material (preferably, hardened steel).
