Movable Protective Shield for Active Protection Repercussions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing active protection systems on military vehicles increase the vehicle's overall dimensions, limiting operational capabilities and requiring additional transport volume due to their placement on mounting arms or the vehicle's highest point, causing damage to turret components and crew members from countermeasure repercussions.
Innovation Solution
A defense system with a protective device featuring a movably attached shield that absorbs and redirects the repercussions of the distance-active protection system, allowing direct mounting on the vehicle, reducing the vehicle's profile and operational restrictions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the active protection system is mounted 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's overall dimensions increase
Solution Approach 1:
The protective shield is designed to be movable between a first position (extended outward to protect against repercussions) and a second position (retracted to minimize vehicle dimensions). This dynamic positioning allows the vehicle to switch between protection mode and compact mode, resolving the contradiction between protection effectiveness and vehicle size.
Solution Approach 2:
The protection system is segmented into a separate movable shield component that can be independently positioned. Rather than permanently extending the vehicle structure, the shield is a detachable/movable element that provides protection only when needed, thus avoiding permanent increase in vehicle dimensions.
2Length of stationary object
If the active protection system is mounted directly on the vehicle, then the vehicle's overall dimensions are reduced, but the vehicle is exposed to damage from countermeasure repercussions
Solution Approach 1:
The shield transitions from a static extended structure to a dynamic movable component that can be positioned close to the vehicle body when deployed. This allows direct mounting on the vehicle while providing protection, as the shield moves into position only during countermeasure firing rather than permanently extending the vehicle.
Solution Approach 2:
The movable shield acts as an intermediary element between the active protection system and the vehicle body. It absorbs and redirects repercussions away from the vehicle, enabling direct mounting of the protection system while still providing protection through this intermediate protective barrier.
3Reliability
If the protective shield is in the first position, then the vehicle is protected from repercussions, but the field of view of crew members and optics is restricted
Solution Approach 1:
The shield's ability to move between positions allows dynamic adjustment of the field of view. During countermeasure operations, the shield is in the first position for protection. During normal operations requiring clear visibility, the shield can be moved to the second position, dynamically resolving the contradiction between protection and visibility.
Solution Approach 2:
The shield position changes periodically based on operational requirements - extended during countermeasure firing, retracted during normal operations. This periodic positioning ensures protection is provided only when needed, maintaining clear field of view during non-critical periods while protecting the vehicle during critical moments.
