Offset-Hinged Folding Ballistic Shield for Fast One-Handed Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handheld ballistic shields lack ergonomic design, efficient deployment, and compact storage solutions, making them cumbersome for transport and use in high-threat environments.
Innovation Solution
A folding shield design featuring two panels with offset hinges and ergonomic grip and arm supports, allowing the shield to be easily articulated between unfolded and folded states, providing enhanced ergonomics, rapid deployment, and compact storage while maintaining ballistic protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the shield is designed as a rigid single-piece structure, then ballistic protection is maintained, but transport and storage become cumbersome
Solution Approach 1:
The shield is divided into multiple panels (first panel, second panel, third panel) connected by hinges, allowing the rigid ballistic barrier to be segmented into foldable sections that can be compacted for transport while maintaining structural integrity during use
2Length of moving object
If the shield is made foldable for easy transport, then storage capability is improved, but deployment speed and operational readiness deteriorate
Solution Approach 1:
The shield incorporates hinge joints that enable dynamic transition between folded and unfolded states, with the hinges designed to allow rapid one-handed deployment while maintaining stability in the deployed position
Solution Approach 2:
The shield panels and arm supports are pre-configured in the folded state with alignment features that enable quick deployment without requiring complex assembly steps or tools
3Ease of manufacture
If traditional grip handles are used, then manufacturing is simple, but user fatigue increases during extended use
Solution Approach 1:
The shield incorporates curved arm supports with specific geometric profiles designed to match the contours of the user's arm, providing localized ergonomic support at the contact points while maintaining simple manufacturing processes
4Ease of manufacture
If the shield structure is simplified for easy manufacturing, then production cost is reduced, but adaptability to different operational conditions deteriorates
Solution Approach 1:
The shield uses hinge-connected panels that can be positioned at different angles and configurations, allowing the same basic structure to adapt to various operational conditions including different storage spaces, deployment scenarios, and user preferences

AI summary
A folding ballistic shield is provided that has two panels connected along a vertical line that open to less than 180 degrees via an offset coupling mechanism such that the panels also overlap slightly to prevent any gap or ballistically weak area. A pair of grip handles and arm braces or supports on each panel allow users to more easily support the shield with either his or her left or right hand/arm.
