Ballistic Protection Element with Reinforced Central Stack
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bulletproof vests do not provide sufficient protection against projectiles fired by long guns, requiring additional rigid ballistic protection plates that complicate user logistics and increase vest deployment time.
Innovation Solution
A ballistic protection element integrated into a bulletproof vest, comprising two stacks of fiber-based layers with high molecular weight polyethylene and aramid fibers, bonded in a thermoplastic matrix, providing enhanced protection against both handgun and long gun ammunition without the need for additional plates, ensuring ergonomic and comfortable wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional rigid ballistic protection plates are added to provide protection against long gun projectiles, then protection performance is improved, but device complexity and ease of operation deteriorate due to logistics management requirements
Solution Approach 1:
The patent combines multiple ballistic protection functions into a single integrated element. The first stack provides Level IIIA protection while the second stack provides Level III protection, merging what were previously separate protection plates into one unified component that eliminates logistics management complexity.
Solution Approach 2:
The single ballistic protection element serves multiple protection functions simultaneously. It provides both Level IIIA protection (first stack) and Level III protection (second stack), making the vest universally protective against different threat levels without requiring separate plates.
2Reliability
If additional rigid ballistic protection plates are added to provide protection against long gun projectiles, then protection performance is improved, but ease of operation worsens due to increased vest deployment time
Solution Approach 1:
By merging the first stack and second stack into a single integrated ballistic protection element, the patent eliminates the time required to assemble or attach separate protection plates. The user simply puts on the complete protective element, significantly reducing deployment time.
3Ease of operation
If the surface dimensions of the second stack are made smaller than the first stack, then ergonomic comfort is improved, but protection coverage area is reduced
Solution Approach 1:
The patent applies local quality by having the second stack (Level III protection) concentrated in the central part where vital organs are located, while the first stack (Level IIIA protection) covers the entire surface including peripheral areas. This localized approach provides enhanced protection where most needed while maintaining ergonomic comfort.

AI summary
The invention relates to a ballistic protection element (10) for protecting the torso and/or back of a person. Said element (10) comprises, in the body thereof: a first stack (13) of a plurality of fiber layers (14) having surface dimensions capable of covering the torso or back of the person; and a second stack of a plurality of fiber layers that have surface dimensions smaller than the surface dimensions of the first stack (13) and are placed on top of said first stack (13) at a central portion (11) of the protection element (10) so as to form a reinforcement in said central portion (11). The layers of the first (13) and second stack are connected to each other in a binder matrix, at least in said central portion (11).
