Solution Overview

Problem

Conventional impact protection devices, such as helmets, rely on G-force measurements for testing, which is an incomplete metric for determining concussion safety. This approach fails to effectively reduce impact pressure on the body, leading to potential injuries even if G-force measurements are within acceptable ranges.

Innovation Solution

The development of a body impact protection system that incorporates a force defusing structure with angled components and varying material compositions. This system disperses impact force components over a larger area, reducing pressure on the body through a multi-layered approach that includes inner and outer layers with specific geometric and material properties.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If conventional G-force based testing is used for helmet safety evaluation, then testing simplicity is maintained, but impact pressure reduction effectiveness is insufficient

Engineering Contradiction:

Improvetesting simplicityVSAvoidimpact pressure

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

The patent transitions from testing based on G-force (acceleration) to testing based on impact pressure (force per unit area). This parameter change reveals that conventional helmets fail to adequately reduce impact pressure even when they pass G-force tests, leading to the development of new helmet structures optimized for pressure reduction rather than just acceleration control.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent replaces the conventional mechanical testing approach (G-force measurement) with a new mechanical approach (impact pressure measurement). This substitution allows for more accurate assessment of concussion risk by directly measuring the pressure applied to the brain during impact, leading to improved helmet design criteria.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If impact distance is increased to reduce G-force, then G-force measurement improves, but impact pressure reduction is not adequately addressed

Engineering Contradiction:

ImproveG-force testing resultVSAvoidimpact pressure

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a new dimension to impact protection by considering impact pressure (force distributed over area) in addition to the traditional G-force (acceleration) dimension. This dimensional expansion reveals that increasing impact distance alone is insufficient, as it does not address the concentration of force on specific areas of the head that cause concussions.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Ease of manufacture

If conventional helmet structure with rigid shell and foam padding is used, then manufacturing simplicity is maintained, but impact pressure distribution is insufficient

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidimpact pressure distribution

Core Design Contradiction:

Ease of manufactureVSStress or pressure

Solution Approach 1:

The patent divides the helmet structure into multiple functional layers with distinct purposes: an outer rigid shell for structural integrity, an intermediate layer for force distribution, and an inner foam padding for cushioning. This segmentation allows each layer to optimize its function, improving impact pressure distribution while maintaining manufacturing feasibility through standardized layer assembly.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent employs composite material construction by combining rigid materials (for the outer shell) with foam materials (for the inner padding and intermediate layers). This composite approach leverages the strengths of each material type - the rigid shell provides structural support while the foam layers provide pressure distribution and cushioning - creating a helmet that effectively reduces impact pressure.

Inventive Principle:

Principle #40Composite materials

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 body impact protection system significantly reduces the impact pressure on the body by spreading the force over a larger area, thereby enhancing concussion safety beyond what is achieved through conventional G-force based testing. This is demonstrated by reducing the impact pressure from approximately 770 PSI to about 36 PSI in a helmet scenario, substantially lowering the risk of injury.

AI summary

A defusing cell includes walls and spheroid elements. The walls are physically connected together to form a first perimeter, a second perimeter, and a hollow center region. A wall has a length and is an angle with respect to the first perimeter. The first perimeter is separated from the second perimeter by a distance based on the length and an angle of the wall. The second perimeter is larger than the first perimeter. The spheroid elements are arranged in a pattern to distribute and disperse an impact force impacting the defusing cell from the second perimeter with respect to the first perimeter.
