Solution Overview

Problem

Existing protective gowns in the healthcare industry are uncomfortable due to heat management issues, particularly during prolonged procedures, and lack efficient heat dissipation mechanisms.

Innovation Solution

A rear-opening protective gown with a ventilation cape and mesh lining that allows for air exchange, combined with a pull-forward doffing mechanism and electrostatic dissipative yarns for improved comfort and reusability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a protective gown is designed to provide effective barrier protection, then protection against microorganisms and body fluids is improved, but heat management and wearer comfort deteriorate

Engineering Contradiction:

Improvebarrier protectionVSAvoidheat management

Core Design Contradiction:

ReliabilityVSTemperature

Solution Approach 1:

The gown is divided into distinct functional layers: an outer barrier layer for protection and an inner breathable layer for comfort. The back panel is segmented into multiple sections with varying degrees of openness, allowing different areas to serve different functions - some areas provide maximum protection while others allow heat dissipation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different portions of the gown have different properties - the front and sides maintain full barrier coverage while the back panel incorporates ventilation openings and breathable materials. This local differentiation allows the gown to provide both protection and heat management simultaneously in different regions.

Inventive Principle:

Principle #3Local quality

2Duration of action of stationary object

If a protective gown is designed to be reusable, then cost-effectiveness and sustainability are improved, but ease of removal and doffing safety deteriorate

Engineering Contradiction:

ImprovereusabilityVSAvoiddoffing ease

Core Design Contradiction:

Duration of action of stationary objectVSEase of operation

Solution Approach 1:

The gown incorporates pre-designed removal features such as colored pull tabs or markers that indicate the correct doffing sequence and location. These features are built into the gown during manufacturing, enabling safe and easy removal without requiring the wearer to figure out the process.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Colored elements are incorporated into the gown to guide the doffing process. Different colors indicate different zones or features, making it easier for the wearer to identify the correct removal path and sequence, thereby improving ease of operation while maintaining reusability.

Inventive Principle:

Principle #32Color changes

3Reliability

If a protective gown uses traditional materials for barrier protection, then protection effectiveness is improved, but breathability and comfort deteriorate

Engineering Contradiction:

Improveprotection effectivenessVSAvoidbreathability

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The gown uses composite construction combining traditional barrier materials with breathable fabrics. The outer layer provides protection while the inner layer or specific panels use breathable materials like mesh or perforated fabrics, creating a composite structure that delivers both protection and breathability.

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 gown provides enhanced comfort and heat management through ventilation and breathable materials, while maintaining effective barrier protection and ease of use.

AI summary

A reusable, rear-opening protective gown having comfort features is provided. The gown includes a central gown body including a front panel and a back panel. The gown opens at the back panel. A plurality of fastening elements is positioned on or proximate to the back panel, with each fastening element including first and second fasteners configured to engage with one another to define a selectively releasable connection. The gown further includes a ventilation cape formed by a ventilation opening in the central gown body, wherein the ventilation opening facilitates heat management and increases comfort for a wearer within the gown while still providing splash protection at the location of heat venting. Additional features of the gown further help dissipate heat from the user while adding comfort in additional manners (including lowering visual strain) for users in medical settings such as operating rooms.
