Vehicle Cell Decoupling Assembly for Blast Projectile Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protected vehicles face challenges in preventing additional components like bulkheads and partitions from accelerating and acting as projectiles due to buckling under blast forces, leading to complex and heavy constructions that may not fully prevent energy transfer.
Innovation Solution
A vehicle cell with a connection and decoupling apparatus using a hook and loop fastener to mechanically decouple additional components from structural components during deformation, ensuring no energy or acceleration is transferred.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If additional components are rigidly attached to structural components, then stability and structural integrity are improved, but the additional components can buckle and accelerate under blast forces, creating projectile hazards
Solution Approach 1:
The connection transitions from rigid to dynamic during blast events. The decoupling apparatus remains connected during normal operation but automatically releases when blast forces exceed threshold levels, allowing the additional component to move independently and preventing buckling-induced projectile hazards while maintaining structural integrity during normal use
2Object-affected harmful factors
If additional components are suspended decoupled from structural components, then projectile hazards are reduced, but the construction becomes more complex and heavier
Solution Approach 1:
The harmful function of rigid connection (force transfer during blast) is extracted from the connection system while retaining the useful function (structural support during normal operation). The decoupling apparatus selectively removes the force-transfer capability only when blast forces are detected, simplifying the overall construction compared to fully suspended systems
3Shape
If bulkheads or partitions are bent to prevent buckling, then deformation control is improved, but installation space requirements increase and construction difficulty increases
Solution Approach 1:
The decoupling apparatus acts as an intermediary between the additional component and structural component. Instead of modifying the shape of bulkheads or partitions, this intermediary device absorbs the blast forces and prevents them from being transferred to the additional components, eliminating the need for complex curved designs and simplifying installation

AI summary
A vehicle cell for a protected vehicle includes an assembly having a structural component, an additional component arranged within the vehicle cell, and a connection and decoupling apparatus that connects the additional component to the structural component. The connection and decoupling apparatus is configured to mechanically decouple the additional component from the structural component in the event of a deformation of the structural component resulting from a blast acting on the structural component. In one example the connection and decoupling apparatus is a hook and loop fastener.
