Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ballistic shields do not adequately address the need for a portable, versatile, and effectively rated shield that can protect against various threat levels while maintaining mobility and visibility.
Innovation Solution
A portable ballistic shield design featuring a composite or metal shield body with a viewport, front and back bezels, and a gasket system, which includes washer assemblies with ballistic cones and springs to absorb shock and enhance protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the shield body is made with composite or metal materials to meet higher threat level ratings, then ballistic protection is improved, but weight increases reducing mobility
Solution Approach 1:
The shield body is constructed using composite materials that combine multiple substances to achieve high ballistic protection ratings (III, IIIA, IV) while managing weight. The composite structure integrates different material properties to resist various threat levels including handgun, rifle, and piercing rifle threats.
Solution Approach 2:
The shield is divided into multiple functional components including the shield body, viewport, front bezel, back bezel, and gasket system. This segmentation allows each component to be optimized for its specific function while collectively providing comprehensive protection with reduced overall weight.
2Ease of operation
If a viewport is added to the shield body to maintain visibility, then operational visibility is improved, but structural integrity and ballistic protection may be compromised
Solution Approach 1:
The viewport is strategically positioned and constructed with materials specifically optimized for transparency and impact resistance. The surrounding bezels provide localized reinforcement around the viewport opening, ensuring that the area around the visibility feature maintains structural integrity and ballistic protection equivalent to the rest of the shield body.
3Reliability
If bezels and gaskets are added to seal and protect the viewport, then protection against debris and water ingress is improved, but device complexity increases
Solution Approach 1:
The gasket is pre-installed on the back surface of the shield body before attaching the viewport and bezels. This preliminary placement ensures proper sealing alignment and protects the viewport assembly from water and debris ingress without requiring complex sealing mechanisms during assembly.
Solution Approach 2:
The front bezel, back bezel, and gasket work together as an integrated sealing system. The front bezel covers the front surface and viewport, the gasket seals the back surface and viewport, and the back bezel provides additional protection, combining multiple protective functions into a unified assembly.
4Reliability
If washer assemblies with ballistic cones and springs are used to connect components, then shock absorption and component protection are improved, but manufacturing complexity increases
Solution Approach 1:
Ballistic cones and springs are integrated into the washer assemblies that connect the bezels to the shield body. These components are pre-configured to absorb shock and protect the viewport and other components from impact forces before damage can occur, providing built-in protection without requiring separate cushioning systems.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The shield effectively meets threat levels IIIA handgun, III rifle, or level IV piercing rifle ratings, providing enhanced ballistic protection while maintaining mobility and visibility through its design features.
Implementation Method 1
a spring disposed on the shank, wherein the ballistic cone is configured to move along the shank in response to application of a force to the ballistic cone
