Bulletproof Vest Panels with Mixed Satin Full Weave
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bullet-proof vests are not sufficiently light while effectively stopping bullets and minimizing trauma to the wearer, as they do not adequately address the deformation and impact effects of projectile impacts.
Innovation Solution
A bullet-resistant article comprising a stack of panels with a first panel of nonwoven sheets, a second woven panel with aramid fibers covered in thermoplastic material, and an intermediate panel with a mixed satin and full weave pattern, which increases projectile deformation and minimizes traumatic effects, along with additional nonwoven panels for enhanced protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a stack of fiber-based panels is used to stop bullets effectively, then the protective performance is improved, but the weight of the garment increases
Solution Approach 1:
The protective vest is divided into multiple functional panels (first panel with non-woven sheets, second panel with woven aramid fibers, and intermediate panels with mixed satin and full weave) stacked in sequence. Each panel segment performs a specific function in the bullet-stopping process, allowing the system to achieve high protective performance while optimizing the weight distribution and material usage of each individual layer.
Solution Approach 2:
The invention uses composite material structures combining different fiber types and weave patterns. The intermediate panels specifically combine satin weave portions (for flexibility and comfort) with full weave portions (for high strength and bullet resistance). This composite approach allows the garment to achieve superior protective performance per unit weight compared to single-material constructions.
2Object-affected harmful factors
If the garment structure is optimized to minimize deformation and trauma to the body, then the wearer comfort is improved, but the bullet-stopping capability may be compromised
Solution Approach 1:
The intermediate panels feature local quality variation through the checkerboard pattern of satin and full weave portions. The full weave portions are strategically positioned to provide high strength and bullet resistance where needed, while the satin weave portions provide flexibility and comfort in other areas. This local differentiation allows the garment to simultaneously achieve trauma minimization and effective bullet stopping.
Solution Approach 2:
The intermediate panels with mixed weave patterns act as a cushioning layer positioned between the bullet-facing first panel and the body-contacting second panel. This intermediate cushioning structure is designed to deform in a controlled manner to absorb impact energy before it reaches the wearer's body, thereby minimizing trauma while maintaining overall bullet-stopping capability.
3Weight of moving object
If lighter materials are used to reduce garment weight, then the wearer comfort is improved, but the protective performance against bullets decreases
Solution Approach 1:
The garment uses composite material construction combining lightweight non-woven sheets in the first panel with woven aramid fibers in the second panel, interconnected through intermediate panels. This composite structure achieves high protective performance per unit weight by optimizing the contribution of each material type, leveraging the strengths of different fiber systems to maximize protection-to-weight ratio.
Solution Approach 2:
The protective system is segmented into multiple functional layers, each using materials optimized for its specific role. The first panel uses lightweight non-woven material for initial bullet contact, the intermediate panels use mixed weave patterns for energy absorption, and the second panel uses woven aramid for structural integrity. This segmentation allows each layer to be optimized for its function while keeping the overall garment weight minimized.

Function Achieved in This Case
The solution results in a lighter bullet-resistant garment that effectively stops bullets and projectiles while reducing trauma by increasing projectile deformation and minimizing impact effects, using a combination of nonwoven and woven panels with specific stitching and thermoplastic materials.
Implementation Method 1
a respective thermoplastic sheet fixed to one face of the weave, the fixing of the thermoplastic sheet to the fiber weave being such that the sheet and the fabric form the second panel as a whole
