Segmented Aluminum Panels for Armored Vehicle Equipment Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective nets in armored infantry vehicles are insufficient to securely maintain heavy and violently projected equipment during blasts, as they lack the necessary rigidity and strength due to their design, which is not suited for large storage spaces with varied and heavy loads.
Innovation Solution
A protective device comprising multiple rectangular panels made of lightweight yet rigid aluminum alloy, secured by straps and a flexible fabric envelope, which can extend over the entire length and height of storage spaces, and attach to the vehicle's body at low and high fixing points, allowing for easy detachment and folding when not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a flexible plastic mesh net is used to protect against equipment projection, then the device is easy to install and remove, but the net lacks sufficient strength and rigidity to securely maintain heavy equipment during violent projection
Solution Approach 1:
The protective screen is divided into multiple rigid panels that can be segmented for easier handling and installation. Each panel can be independently positioned and secured, allowing the overall structure to maintain strength while improving ease of operation during deployment and removal.
Solution Approach 2:
The invention changes the fundamental parameter of the protective structure from flexible (mesh net) to rigid (panel-based construction). This parameter change enables the structure to withstand violent equipment projection while still allowing for practical installation and removal through the modular panel design.
2Area of stationary object
If a protective net of considerable length is produced to cover large storage spaces, then the coverage area is increased, but the net has insufficient rigidity to ensure secure maintenance of heavy equipment
Solution Approach 1:
The large-area protective screen is segmented into multiple rigid panels that can be assembled to cover extensive storage spaces. Each panel maintains structural rigidity independently, and when combined, they form a stable overall structure capable of covering large areas while securing heavy equipment.
Solution Approach 2:
The protective structure uses composite construction with rigid panels formed from reinforced materials. This composite approach enables each panel to maintain high rigidity while the assembled structure achieves the necessary coverage area for large storage spaces in armored vehicles.
3Strength
If a rigid panel-based protection system is used to securely maintain heavy equipment, then the strength and rigidity are sufficient, but the device becomes more complex and harder to detach
Solution Approach 1:
The protective screen is segmented into standardized rigid panels with uniform connection mechanisms. This segmentation reduces device complexity by creating modular units that can be easily assembled and detached using simple, repetitive connection procedures rather than complex custom-fitted structures.
Solution Approach 2:
The panel-based system uses universal connection mechanisms that can be applied to all panels and storage space configurations. This multi-functionality reduces operational complexity by allowing the same attachment and detachment procedures to be used regardless of the specific deployment scenario.

AI summary
The device (1) has a maintenance screen (7) extending on entire length (L) and height (H) of a storage space (2). The screen is fixed at bottom fixation points (8) secured to a body (4) of a vehicle and removably fastened to top fixation points (10) secured to the body. Length of rectangular panels (7a-7c) is longer than that of the space, where the panels are made of aluminum alloy. The panels are stacked on each other when the device is in a folded position and positioned in extension of each other to close the space when the device is in a closing position.
