Solution Overview

Problem

Existing protective gear, such as athletic equipment, is not optimally designed to mitigate bodily injuries from falls and is cumbersome and expensive, while there is a need for a protective clothing system that is affordable, unobtrusive, and can also serve as a floatation device.

Innovation Solution

A protective clothing system incorporating polyethylene foam attached to garments to protect vulnerable body parts during falls and function as a floatation device, featuring lightweight, water-resistant, and inert closed-cell polyethylene foam for impact protection and buoyancy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional athletic protective equipment is used, then impact protection is provided, but the equipment is expensive and cumbersome to wear

Engineering Contradiction:

Improveimpact protectionVSAvoidease of wear

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

The patent uses thin-film foam layers integrated into clothing rather than bulky traditional protective gear. The foam is sandwiched between fabric layers to create a flexible, lightweight protective barrier that conforms to the body while providing impact cushioning, eliminating the need for cumbersome external pads and helmets

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The invention combines multiple materials including foam, fabric, and adhesive layers to create an integrated protective clothing system. This composite structure provides both protection and comfort while reducing overall weight and bulk compared to traditional single-material protective equipment

Inventive Principle:

Principle #40Composite materials

2Strength

If traditional athletic protective equipment is used, then impact protection is provided, but the equipment is expensive to purchase

Engineering Contradiction:

Improveimpact protectionVSAvoidcost

Core Design Contradiction:

StrengthVSEase of manufacture

Solution Approach 1:

The patent employs inexpensive foam materials and simple adhesive bonding techniques that allow for cost-effective production. The protective layers can be manufactured at low cost and disposed of or replaced as needed, eliminating the need for expensive, durable athletic equipment while maintaining adequate protection

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The invention changes the material parameters by using thin-film foam rather than thick dense foam, and by using adhesive bonding rather than complex fastening mechanisms. These parameter changes significantly reduce manufacturing costs while maintaining the essential protective function

Inventive Principle:

Principle #35Parameter changes

3Strength

If polyethylene foam is used for protection, then impact mitigation is achieved, but the foam must be attached to clothing

Engineering Contradiction:

Improveimpact mitigationVSAvoidattachment requirement

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

The patent uses adhesive as an intermediary substance to bond the foam protective layers to the clothing fabric. This simple adhesive layer eliminates the need for complex fastening systems, buttons, zippers, or straps, providing a clean and simple attachment method that maintains the integrity of both the foam and clothing

Inventive Principle:

Principle #24Intermediary (Mediator)

4Strength

If protective clothing is designed for fall protection, then impact protection is provided, but it must also function as flotation device

Engineering Contradiction:

Improveimpact protectionVSAvoiddual function requirement

Core Design Contradiction:

StrengthVSAdaptability or versatility

Solution Approach 1:

The patent designs the protective clothing system to serve multiple functions: the foam layers provide impact protection during falls while simultaneously providing buoyancy for water flotation. The same foam material and clothing structure that cushion impacts also keep the wearer afloat in water, eliminating the need for separate protective and flotation equipment

Inventive Principle:

Principle #6Universality (Multi-functionality)

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 system effectively reduces impact injuries during falls and provides flotation support, offering comprehensive protection without the bulk and high cost of traditional athletic gear.

Implementation Method 1

A polyethylene foam is attached to the clothing. The polyethylene foam is positioned on the clothing to protect a portion of the user's body from impacts due to a fall.

Methodology Applied

Scientific EffectImpact absorption: Damping

Implementation Method 2

The protective clothing system is configured to function as a flotation device to keep the user afloat in water that the user has fallen into.

Methodology Applied

Scientific EffectBuoyancy: Archimedes' Principle (Buoyancy)
