Canted Linear Shaped Charge Support for Concrete Breaching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Linear shaped charges face difficulties in cutting through reinforced concrete structures due to the inherent properties of concrete and steel, and existing methods struggle to efficiently create rectangular or square breach openings, which are more effective for rapid ingress and egress.
Innovation Solution
The use of linear shaped charges in a canted configuration, supported by specialized structures, allows for deeper penetration and effective cutting of corners in reinforced concrete by optimizing the orientation and alignment of the charges to intersect within the target material, utilizing both linear and non-linear shaped charges to enhance cutting efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If linear shaped charges are used to cut reinforced concrete, then cutting capability is improved, but penetration depth is insufficient
Solution Approach 1:
The patent applies asymmetry by configuring the linear shaped charge at a cant angle (non-zero angle) relative to the normal of the target surface, rather than perpendicular alignment. This asymmetric orientation allows the charge to intersect corners and achieve both cutting action and penetration depth simultaneously, resolving the contradiction between cutting capability and penetration depth.
Solution Approach 2:
The patent introduces a new dimensional parameter by adding the cant angle dimension to the traditional perpendicular charge configuration. This angular dimension allows the shaped charge jet to traverse both the surface cutting path and the depth penetration path, enabling simultaneous achievement of cutting capability and penetration depth through three-dimensional geometric optimization.
2Productivity
If linear shaped charges are used to cut reinforced concrete, then cutting capability is improved, but time for breach creation increases
Solution Approach 1:
The asymmetric cant angle configuration enables the shaped charge to cut corners and create rectangular openings more efficiently by eliminating the need for multiple sequential charges, thereby reducing the total time required for breach creation while maintaining cutting capability.
Solution Approach 2:
The patent merges multiple functions into a single charged configuration: the canted linear shaped charge simultaneously performs cutting, corner intersection, and penetration in one operation, consolidating what would traditionally require multiple separate charges and operations into a single time-efficient process.
3Ease of operation
If linear shaped charges are used to create rectangular openings, then ingress and egress efficiency is improved, but cutting effectiveness through steel reinforcement is insufficient
Solution Approach 1:
The canted configuration creates an asymmetric jet trajectory that effectively intersects steel reinforcement bars at optimized angles, enhancing cutting effectiveness through the reinforcement while simultaneously achieving the rectangular geometry needed for efficient ingress and egress.
Solution Approach 2:
The patent changes the geometric parameter of charge orientation from perpendicular to canted, which fundamentally alters the jet trajectory and interaction with steel reinforcement, thereby improving cutting effectiveness through the reinforcement structure while maintaining the desired rectangular opening shape.
