Pivotable Military Vehicle Shield Against Standoff-Active Repercussions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing standoff-active protection systems for military vehicles increase the vehicle's contour, limiting operational capabilities and requiring additional transport volume, due to their arrangement on mounting arms or the vehicle's highest point, which exposes crew and optics to repercussions from the system's countermeasures.
Innovation Solution
A movable protective shield is mounted directly on the vehicle, absorbing and redirecting the effects of the standoff-active protection system, allowing it to be positioned compactly when not in use and providing a viewing window for crew visibility while deflecting countermeasure repercussions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the standoff-active protection system is arranged on a mounting arm or at the highest point of the vehicle, then the vehicle is protected from repercussions of the protection system, but the vehicle contour is excessively increased
Solution Approach 1:
The protective shield is designed to be movable between a deployed position (providing protection) and a retracted position (minimizing contour). This dynamic configuration allows the vehicle to switch between protected and compact states, resolving the contradiction between protection and vehicle size.
Solution Approach 2:
The protective shield can be positioned to nest over the standoff-active protection system when retracted, creating a compact integrated structure. This nesting approach minimizes the overall vehicle contour while maintaining all protective functions when not in use.
2Object-affected harmful factors
If the protective shield is positioned to provide full protection, then crew and optics are protected from repercussions, but the field of vision is blocked
Solution Approach 1:
The protective shield incorporates transparent or translucent sections at strategic locations to maintain visibility while providing protection. This local modification allows light to pass through while the rest of the shield structure blocks repercussions, resolving the contradiction between protection and visibility.
Solution Approach 2:
The shield is divided into protected zones and transparent zones, with different optical properties in different sections. This segmentation allows the shield to simultaneously provide protection in critical areas while maintaining visibility where needed for operational awareness.
3Length of stationary object
If the standoff-active protection system is mounted directly on the vehicle, then the vehicle contour is reduced, but the vehicle is exposed to repercussions from countermeasures
Solution Approach 1:
The protective shield is designed to be movable between a deployed position (providing protection) and a retracted position (minimizing contour). This dynamic configuration allows the vehicle to switch between protected and compact states, resolving the contradiction between protection and vehicle size.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution reduces the vehicle's contour, enhances operational flexibility, and protects crew and optics from system repercussions by redirecting blasts and projectile remnants, while maintaining visibility and reducing vibration impact on the viewing window.
Implementation Method 1
The protective shield can absorb and/or redirect the effects of the proximity-active protection system
Implementation Method 2
The protective shield can absorb and/or redirect the effects of the proximity-active protection system
