Offset Grid Ballistic Protection for Door Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ballistic protection grids for military vehicles complicate access and egress due to their design, requiring complex manipulation and often necessitating a third person to close or open the openings, disrupting the conventional use of doors or hatches.
Innovation Solution
A remote ballistic protection device featuring two offset grids with parallel bars, where the second grid is positioned to allow its bars to pass between those of the first grid during pivoting, ensuring the grids remain in parallel planes when closed, with a rigid edge and uprights to maintain optimal protection and prevent mechanical interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If protective grids are placed at a distance from the wall to ensure correct operation, then ballistic protection is improved, but access and egress become complicated requiring complex manipulation and external assistance
Solution Approach 1:
The protective grid is divided into two separate grids (first grid fixed to wall, second grid movable with door) that can operate independently. This segmentation allows the first grid to maintain fixed ballistic protection while the second grid facilitates door operation without requiring complex manipulation of a single large grid structure.
Solution Approach 2:
The second grid acts as an intermediary element between the door and the first grid. It can pass through the opening created by the first grid during door operation, serving as a mediator that enables access while maintaining protection when the door is closed.
2Reliability
If conventional protective grids are used, then ballistic protection is provided, but the manipulation process becomes long and complex requiring a third person for closing or opening
Solution Approach 1:
By segmenting the grid into two independent grids, the operation time is reduced. The second grid can be quickly maneuvered through the opening without requiring coordinated manipulation of a large single grid structure, eliminating the need for a third person's assistance.
Solution Approach 2:
The second grid is designed to be movable and dynamic, allowing it to be quickly positioned and removed from the opening during door operation. This dynamic capability enables faster manipulation compared to static grid systems, reducing the time required for access and egress.
3Reliability
If grids are positioned to maintain optimal ballistic protection, then protection performance is improved, but mechanical interference between grids occurs during pivoting
Solution Approach 1:
The grids are positioned in different spatial planes or dimensions relative to each other. The second grid is offset from the first grid such that they exist in separate planar positions, allowing the bars of the second grid to pass between the bars of the first grid during pivoting without mechanical interference, while both maintain optimal protection when closed.

AI summary
The invention relates to a remote ballistic protection device protecting a wall comprising an opening (200), a device comprising at least a first grid (1) offset from the wall comprising a first series of bars (1a) parallel to each other and substantially perpendicular to the pivot axis (400) of a hinge (300) of the opening (200).This ballistic protection device (101) is characterized in that it comprises a second grid (2) offset from the opening (200) and comprising a second series of bars (2a) substantially parallel to the first series of bars (1a), the second grid (2) being positioned relative to the first grid (1) such that its bars (2a) are spatially offset in the plane of the second grid (2) relative to the bars (1a) of the first grid, the bars (2a) of the second grid (2) thus being able to pass between the bars (1a) of the first grid (1) when pivoting the opening (200).
