Offset Ballistic Shield Structure for Closer Shot Spacing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ballistic shields face challenges in effectively stopping projectiles while maintaining compactness and allowing closer shot spacing, as they often require multiple layers to prevent penetration, which increases weight and thickness.
Innovation Solution
A multi-piece ballistic shield design with offset spaced components, including a first shield portion and a second layer offset from the primary shield, which creates air gaps to destabilize projectiles, reduce layer exposure, and allow for thinner, lighter construction without compromising protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple layers are used to prevent penetration, then protection reliability is improved, but weight and thickness increase
Solution Approach 1:
The patent introduces air gaps between ballistic layers, transitioning from a compact multi-layer structure to a spaced multi-layer structure. This dimensional change in layer arrangement allows the shield to maintain protection reliability while reducing overall thickness and weight, as the air gaps provide additional protective functionality without adding material mass.
Solution Approach 2:
The patent uses air gaps as an intermediary element between ballistic layers. These air gaps serve as a mediator that destabilizes projectiles and reduces layer exposure to direct impact, thereby maintaining or improving protection reliability while avoiding the need for additional heavy materials.
2Reliability
If multiple layers are used to prevent penetration, then protection reliability is improved, but thickness increases
Solution Approach 1:
The patent introduces air gaps between ballistic layers, transitioning from a compact multi-layer structure to a spaced multi-layer structure. This dimensional change in layer arrangement allows the shield to maintain protection reliability while reducing overall thickness and weight, as the air gaps provide additional protective functionality without adding material mass.
3Object-affected harmful factors
If offset spaced components are used, then projectile destabilization is improved, but device complexity increases
Solution Approach 1:
The patent divides the shield into multiple separate ballistic layers with air gaps between them, rather than using a single solid structure. This segmentation allows each layer to be positioned at different offsets, creating effective projectile destabilization while maintaining manufacturing simplicity through modular construction.

AI summary
A multi-piece ballistic shield is provided with a first shield having an outward face exposed to projectiles and an opposing inward face. The first shield having a first offset layer mechanically coupled to a first section of the outward face of the first shield and a second offset layer mechanically coupled to a second section of the outward face of the first shield. The multi-piece ballistic shield further includes a second shield having an outward face exposed to projectiles and an opposing inward face. The second shield is detachably coupled to the first shield such that the second offset layer overlaps a seam formed between the first and second shields. The multi-piece ballistic shield includes a harness coupled to a fastener to support a weight of the multi-piece ballistic shield.
