Ballistic Door Cover with Slide Hinge Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote ballistic protection devices for military vehicle doors lack complete coverage and require external intervention for opening and closing, resulting in unprotected areas near the hinges and limited accessibility from inside the vehicle.
Innovation Solution
A remote protection device with a slide mechanism integral to the door, allowing the ballistic protection panel to follow door movements without interference, and enabling independent opening and closing from inside the vehicle, facilitated by a control rod and pivot connections that allow the slide to engage or disengage from a hook mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the protection panel is fixed to the door so that it follows door movements, then the door can be opened and closed, but an unprotected area is created near the hinge to allow pivoting movement
Solution Approach 1:
The protection panel is extended in width beyond the door boundaries, covering the hinge area by projecting into the spatial dimension where the hinge operates. This dimensional extension allows the panel to maintain coverage of the hinge region while the door pivots, eliminating the unprotected zone without restricting door movement.
Solution Approach 2:
The connection between the protection panel and door is segmented through an independent hinge mechanism rather than rigid fixation. This allows the panel to be positioned independently to cover the hinge area while the door moves, resolving the conflict between coverage and movement.
2Object-affected harmful factors
If the protection panel is fixed to the door, then complete ballistic coverage is achieved, but external intervention is required to open and close the door
Solution Approach 1:
An intermediary release mechanism is introduced between the protection panel and door hinge connection. This intermediary device allows the crew from inside the vehicle to disengage the panel from the door hinge, enabling independent door operation while maintaining ballistic coverage when engaged.
Solution Approach 2:
The connection between protection panel and door is made dynamic rather than static, allowing it to transition between engaged (ballistic coverage) and disengaged (door operation) states. This dynamic connection enables the system to adapt between protection and operational modes.
3Object-affected harmful factors
If the protection panel completely covers the door, then ballistic coverage is maximized, but the door cannot be opened without external assistance
Solution Approach 1:
The release function is extracted as a separate, simple mechanism from the main hinge structure. This extracted release mechanism can be operated from inside the vehicle to disengage the panel, providing complete coverage when engaged while enabling internal operation without adding significant complexity.

AI summary
The invention relates to a remote protective device (1) designed to completely cover a door (3) and comprising a leaf (6) providing access to the door (3). The leaf (6) and the door (3) each have a hinge (4a, 4b) whose axes of rotation are parallel to each other. The leaf (6) is wider than the door (3) and is positioned opposite it such that the leaf completely covers the door (3), the axis of rotation of the door being aligned with the leaf (6). The leaf (6) also includes at least one guide (7) perpendicular to the axis of rotation (5b) of the leaf (6). The guide is connected to the door by a rigid attachment (8) that is integral with the door (3).
