Bulletproof Umbrella Canopy for Portable Full-Body Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective equipment for soldiers and individuals against bullets and shrapnel, such as hats and clothes, are inadequate in providing comprehensive protection, especially against high-powered gunfire and aerial drone attacks, with limited effectiveness and mobility.
Innovation Solution
A portable umbrella with a canopy made of high-strength bulletproof materials like fabrics, carbon fiber, steel, glass, or ceramics, reinforced with perimeter tapes and optional internal plates, designed to absorb kinetic energy and provide observation slots or glass-covered openings, allowing for quick deployment and visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional protective equipment like hats and clothes with bulletproof material is used, then some protection against bullets and shrapnel is provided, but the protecting effects are still limited and comprehensive coverage is not achieved
Solution Approach 1:
The protective system is divided into multiple functional layers: outer bulletproof fabric layer, intermediate energy-absorbing mattress layer, and inner structural support layer. Each layer performs a specific protective function, collectively providing comprehensive protection against bullets and shrapnel from various directions.
Solution Approach 2:
The invention combines multiple materials with different properties: bulletproof high strength fabrics (Kevlar, polyethylene) for ballistic resistance, stretchy materials (sponge, rubber) for kinetic energy depletion, and steel wires/high strength fibers for structural integrity. This composite structure achieves both reliable protection and comprehensive coverage.
2Illumination intensity
If transparent glass is used as bulletproof material for the umbrella canopy, then visibility is improved, but protection against high-powered gunfire may be compromised
Solution Approach 1:
Different regions of the umbrella canopy have different material properties: the majority uses transparent glass for visibility, while specific high-risk areas are reinforced with bulletproof high strength fabrics and plates to provide enhanced protection against high-powered gunfire.
Solution Approach 2:
The invention changes the material parameters locally by combining transparent glass with bulletproof fabrics and plates, adjusting the balance between transparency and ballistic resistance in different zones of the canopy based on threat assessment.
3Reliability
If the umbrella is made with heavy bulletproof plates and thick materials to stop high firepower bullets, then protection reliability is improved, but portability and ease of carrying deteriorates
Solution Approach 1:
The umbrella employs a collapsible, foldable structure with lightweight connecting elements (perimeter tape, steel rings, loose knots) that allow the heavy protective plates and thick fabrics to be compacted into a portable form factor when not in use, while maintaining full protective capability when deployed.
Solution Approach 2:
The umbrella is designed to be pre-assembled with all protective layers and structural elements in place, allowing the user to simply deploy it when needed rather than assembling heavy components in the field, thus maintaining portability while ensuring complete protection is immediately available.
4Ease of operation
If small holes or narrow slots are made in the umbrella for observation, then visibility is enabled, but protection against bullets and shrapnel is reduced at those points
Solution Approach 1:
Bulletproof glass is used as an intermediary material to cover observation holes and slots. It allows soldiers to view through these openings while maintaining the protective barrier, as the bulletproof glass can withstand bullet and shrapnel impact while being transparent for observation purposes.
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 umbrella effectively protects against bullets and shrapnel from various directions, offering mobility and visibility, suitable for both soldiers in battlefields and civilians in gun violence scenarios, by utilizing high-strength materials to absorb and deflect projectiles.
Implementation Method 1
A mattress of stretchy material, e.g., sponge or rubber, can be added between two layers of the bulletproof fabrics or carbon fabrics to deplete the kinetic energy of a bullet or shrapnel.

AI summary
This invention makes a carriable equipment protecting soldiers or people against bullets from guns or shrapnel from explosive exploding. Many soldiers were killed or injured in a war. Many people were killed or injured by gun shootings in U.S. Bulletproof material with high stiffness and tensile strength, e.g., high strength fabrics, carbon fabrics, bulletproof steel, ceramics, glasses and alloy, has been developed with new technology. Multi-layers of high strength fabrics or carbon fabrics or a plate of bulletproof material is hard to be penetrated by a flying bullet or shrapnel, but existing bulletproof hats or clothes only has partial protecting effect. If the canopy of an umbrella is made of bulletproof fabrics or carbon fabrics or plates of bulletproof material, this umbrella can fully protect soldiers or people behind the umbrella canopy from bullets or shrapnel.
