Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bulletproof structures are inadequate against high-speed bullets due to their inability to effectively absorb and distribute the kinetic energy of modern firearm attacks, leading to mobility issues with heavier armor designs.
Innovation Solution
A hybrid-layered cell comprising a viscous absorber layer, a first elastic metal layer, and a second elastic metal layer, arranged in a lamination manner, with a viscous-elastic foundation layer to slow down and distribute the impact of a bullet, reducing penetration and allowing for easier maintenance by replacing individual cells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional armor is made heavier to resist bullets, then bulletproof ability is improved, but mobility deteriorates
Solution Approach 1:
The patent employs a composite structure consisting of multiple layers with different material properties: a viscous layer (non-Newtonian fluid) for energy absorption, an elastic layer for deformation and energy dissipation, and a hard layer for structural support. This multi-material composite approach achieves superior bulletproof performance without requiring excessive weight, as each layer contributes differently to stopping the bullet.
Solution Approach 2:
The armor is divided into functionally distinct layers: the viscous absorber layer, the elastic metal layer, and the hard layer. Each layer performs a specific function in the bullet-stopping process - the viscous layer absorbs impact energy, the elastic layer deforms to dissipate energy, and the hard layer provides structural integrity. This segmentation allows optimization of each layer's weight and properties independently.
2Ease of manufacture
If armor uses simpler structure, then ease of manufacture is improved, but bulletproof ability deteriorates
Solution Approach 1:
The patent combines multiple materials with distinct properties (viscous non-Newtonian fluid, elastic metal, hard material) in a layered composite structure. This composite approach achieves superior bulletproof ability that would be difficult to obtain with a single material, while maintaining relative manufacturing simplicity through lamination techniques.
Solution Approach 2:
The complex bulletproof function is segmented across multiple layers, each handling a specific aspect of bullet resistance. This segmentation allows each layer to be manufactured separately using appropriate techniques for that material type, then assembled through lamination, balancing manufacturing ease with performance requirements.
3Ease of manufacture
If armor uses uniform material throughout, then manufacturing is simplified, but energy absorption ability deteriorates
Solution Approach 1:
The patent applies the principle of local quality by giving each layer different material properties suited to its specific function: the viscous layer has high energy absorption capacity, the elastic layer has high deformability, and the hard layer has high strength. This localized optimization of material properties maximizes overall kinetic energy absorption while maintaining manufacturing feasibility through standardized layering processes.
