Dual Layer Wrap Package for Aseptic Garment Presentation

Solution Overview

Problem

The existing packaging systems for sterilized protective garments, such as surgical gowns, require complex and time-consuming unwrapping procedures, which can lead to sterility loss and increased costs due to the need for frequent replacement if sterility is compromised.

Innovation Solution

A simplified packaging and unwrapping method involving specific folding techniques of two sheets around the item, reducing the number of steps required to open the package while maintaining sterility, eliminating the need for additional sterilizable outer packaging materials.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional multi-step wrapping procedures are used, then sterility protection is maintained, but unwrapping time and complexity increase significantly

Engineering Contradiction:

Improvesterility protectionVSAvoidunwrapping time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The wrapping system is divided into two distinct sheets (first sheet and second sheet) that can be independently folded and positioned. This segmentation allows each sheet to be optimized for specific folding patterns, enabling a simplified unwrapping sequence where sheets are opened in a predetermined order without compromising sterility.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The sheets are pre-folded and positioned around the item in a specific sequence during packaging, creating a nested structure. This preliminary arrangement establishes a clear unwrapping sequence where the first sheet is opened to reveal the second sheet, which is then opened to expose the item, reducing unwrapping steps while maintaining sterility.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If traditional wrapping procedures are used, then sterility is maintained, but the number of unwrapping steps increases

Engineering Contradiction:

Improvesterility maintenanceVSAvoidunwrapping steps

3Reliability

If complex unwrapping procedures are used, then sterility can be maintained, but stress on medical personnel increases

Engineering Contradiction:

Improvesterility maintenanceVSAvoidoperational stress

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The sheets are pre-folded and positioned around the item in a specific sequence during packaging, creating a nested structure. This preliminary arrangement establishes a clear unwrapping sequence where the first sheet is opened to reveal the second sheet, which is then opened to expose the item, reducing unwrapping steps while maintaining sterility.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The wrapping structure is designed to open systematically through its own structural configuration, with the first sheet folding away to reveal the second sheet, which then opens to expose the item. This self-opening mechanism eliminates the need for complex manual manipulation, reducing operational stress while maintaining sterility.

Inventive Principle:

Principle #25Self-service
