Telescopic Ballistic Protection Device for Vehicle Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote ballistic protection devices for structures like military vehicles are bulky, obstructing access and increasing the vehicle's size, and previous solutions either partially address size issues or complicate access to the vehicle's interior.
Innovation Solution
A device featuring telescopic arms and support means with pivoting hinges allows for the attachment of ballistic protection elements to a structure's roof, keeping the protection elements at a distance from the vehicle's walls, enabling easy access and minimizing lateral bulk by positioning the support elements above the protection grids.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed arms are used to position protective elements at a distance from vehicle walls, then protective function is improved, but vehicle size is increased
Solution Approach 1:
The patent applies telescopic arms that can extend and retract dynamically. When extended, the arms position protective elements at an optimal distance for protection; when retracted, they minimize the vehicle's lateral size. This dynamic adjustment resolves the contradiction between maintaining protective distance and reducing vehicle volume.
Solution Approach 2:
The support means are positioned above the protective elements rather than at their level, utilizing the vertical dimension to reduce lateral bulk. This dimensional repositioning allows the protective function to be maintained while minimizing the horizontal space occupied by the support structure.
2Reliability
If protective grids are positioned at a distance from vehicle walls, then protection effectiveness is improved, but access to vehicle interior is hindered
Solution Approach 1:
The telescopic arms can be retracted to allow personnel to access the vehicle interior without obstruction from the protective grids. When access is needed, the arms retract to minimize interference; when protection is prioritized, they extend to maintain optimal protective distance. This dynamic behavior resolves the contradiction between protection effectiveness and ease of access.
3Volume of moving object
If telescopic arms are used to reduce vehicle size, then lateral bulk is minimized, but device complexity is increased
Solution Approach 1:
The telescopic arms utilize a nested structure where segments are contained within one another during retraction, similar to a nested doll. This nesting mechanism efficiently minimizes lateral bulk while maintaining a relatively compact and manageable device complexity, as the nested design inherently reduces the space required for movement and storage.
4Volume of moving object
If support means are positioned above protective elements, then lateral bulk is reduced, but manufacturing complexity is increased
Solution Approach 1:
Positioning the support means in the vertical dimension above the protective elements rather than at their lateral level reduces the horizontal space occupied. This dimensional change, while adding some manufacturing complexity, allows for more efficient use of space and can be implemented using standard structural support configurations adapted to the vertical orientation.

AI summary
The device (1) has an element (3) integral with a structure (100), and receiving a telescopic arm (4). A supporting unit is interdependent of an end of the telescopic arm. A ballistic protection element (101) is attached to the supporting unit by a hinge (5a). The supporting unit comprises a tubular horizontal part (5), which is located above the protection element. The arm and the element are intended to be fixed at the structure levelled with an upper part of the device. The horizontal part is prolonged with ends by a vertical part (5b) on which the protection element is fixed.
