Double Liner Football Helmet Air-Filled Padding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional football helmets with dense foam padding fail to effectively absorb and distribute impact forces, leading to increased risk of concussions and other head injuries due to their stiff construction, which transfers force directly to the skull and brain, and also trap heat and restrict air circulation.
Innovation Solution
The Double Liner Impact Shield Football Helmet features air-filled padding and a unique design with lightweight Vanadium Chromium steel impact bumpers and a Strapped Pad, allowing for better absorption and distribution of impact forces, improved air circulation, and reduced weight, thereby minimizing the transfer of inertia and providing enhanced protection against concussions and other injuries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If dense foam rubber padding is used in conventional helmets, then the helmet structure provides rigid support, but it intensifies impact force transfer to the skull and brain due to its stiff construction
Solution Approach 1:
The helmet padding is divided into multiple independent air-filled bladders arranged in arrays, rather than using solid foam. Each bladder can independently deform to absorb impact energy, preventing the rigid force transfer characteristic of solid foam construction while maintaining structural support.
Solution Approach 2:
The padding material transitions from solid foam rubber to air-filled bladders, fundamentally changing the physical parameters of the padding. This allows the padding to compress and deform under impact, changing the force transfer characteristics from rigid to compliant, thereby reducing impact transmission to the skull and brain.
2Object-affected harmful factors
If high density foam padding is used, then the helmet provides cushioning, but it stores heat and restricts air circulation around the player's head
Solution Approach 1:
The air-filled bladder construction creates a porous, open structure that allows air to circulate freely around the player's head. This eliminates the heat trapping effect of solid foam while maintaining the cushioning function through the compressible air-filled bladders that can deform to absorb impact energy.
3Reliability
If conventional helmet design is used, then the helmet provides basic protection, but it contributes to serious head injuries by transferring hard impact forces directly to the player's skull
Solution Approach 1:
The air-filled bladders are pre-inflated and positioned to provide cushioning before impact occurs. When impact occurs, these pre-positioned air cushions deform to absorb and dissipate impact energy, preventing the direct force transfer to the skull that causes concussions, while maintaining reliable basic protection.
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 Double Liner Impact Shield Football Helmet effectively reduces the impact force on the head by dispersing and cushioning it, providing better protection against concussions and other injuries, while keeping the player cooler and reducing the risk of neck and vertebral injuries from the helmet's weight.
Implementation Method 1
The Inner Liner Impact Shield will provide better protection from Concussions... with its Air Filled Padding that does not hold and store heat from the players head... will help to better protect the football players head and is lighter in weight... allowing for a better circulation of air around the players head
Implementation Method 2
lightweight Vanadium Chromium steel impact bumpers... The Double Liner Impact Shield is designed to lessen the Impact Force to a Football Players Head from the Side, Back, Front, and especially the top

AI summary
The Football Helmet of the present invention will lessen the Impact Force while also lessening the transfer of momentous inertia that carries on unchanged causing concussions. This is done with cushioning by Impact Bumpers located all around the Players Head repelling impacts as they collapse. The top of the Players Head and Neck is protected because the Outer Shield of the Helmet Collapses from top impact by cushioning while repelling that force by being suspended by Springs in Keeper Boxes and also by a Sponge Pad, and Strapped Pad limiting upward thrust of the Players Head and downward thrust of the Outer shield.
