Slat Armor Movable Panel Linkage for Door Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote ballistic protection devices for military vehicle doors fail to provide complete coverage and allow independent opening and closing from inside the vehicle without interfering with the door's movement, resulting in unprotected areas near the hinges.
Innovation Solution
A remote protection device comprising a movable panel articulated on hinges connected to a fixed panel via a connecting rod, ensuring the panel's movement aligns with the door's, with the connecting rod positioned to avoid interference and maintain protection integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed protection panel is attached to the door to follow door movements, then complete ballistic coverage is achieved, but an unprotected area must be left near the hinge to allow door opening and closing
Solution Approach 1:
The protection system is divided into a fixed panel attached to the door and a separate movable panel attached to the vehicle body. The fixed panel moves with the door while the movable panel remains stationary relative to the vehicle, allowing complete coverage without interfering with door operation near the hinge area.
Solution Approach 2:
A connecting rod acts as an intermediary mechanism between the door and the movable protection panel. This rod transmits the door's angular movement to the protection panel, ensuring the panel follows the door's trajectory while maintaining proper spacing to avoid interference with the hinge area.
2Reliability
If protection panels are placed facing the door to provide complete coverage, then ballistic protection is improved, but the crew cannot open or close the panels from inside the vehicle
Solution Approach 1:
Instead of making the panel facing the door fixed and requiring external operation, the invention makes this panel movable and operable from inside the vehicle. The panel can pivot on hinges to open and close, allowing crew members to operate it from the interior while maintaining protection when closed.
3Reliability
If the protection panel is fixed to the door, then the protection follows door movements, but interference occurs between the panel and fixed protection elements near the hinge
Solution Approach 1:
The protection system is segmented into a fixed panel that moves with the door and a separate movable panel that remains relatively stationary. This segmentation allows the fixed panel to provide movement coordination while the movable panel can be positioned to avoid interference with fixed protection elements near the hinge.
Solution Approach 2:
The solution moves the protection panel to another dimension by placing it on the vehicle body rather than directly on the door. The connecting rod provides the dimensional transformation, translating door movement into appropriate panel movement while maintaining spatial separation to avoid interference.
