Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional uncontaminated garments are prone to contamination during the donning process due to extensive handling and require specialized training to avoid outer surface contact, which exposes them to potential contamination.

Innovation Solution

A packaged garment design where the inner surface faces outward, with the outer surface protected by folding the sleeve and leg portions inside the torso portion, allowing easy donning without touching the outer surface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the garment is folded with outer surface facing outward for packaging, then the garment structure is simple and packaging is easy, but the outer surface becomes exposed and susceptible to contamination during donning

Engineering Contradiction:

Improvepackaging simplicityVSAvoidcontamination risk

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The garment is folded inside-out so that the inner surface faces outward and the outer surface is protected by being folded underneath. This inversion ensures that during donning, the wearer handles only the inner surface while the outer surface remains protected and uncontaminated.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The sleeve and leg portions are folded underneath the torso portion, creating a nested structure where the outer surface of the garment is contained within the folded configuration. This nesting protects the outer surface from exposure and contamination during packaging and donning.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Object-affected harmful factors

If the garment requires extensive handling during donning to prevent contamination, then the garment can be kept clean, but the donning process becomes complex and requires specialized training

Engineering Contradiction:

Improvecontamination preventionVSAvoiddonning complexity

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

By folding the garment inside-out with the inner surface facing outward, the design allows the wearer to naturally handle the garment by its inner surface during donning, eliminating the need for specialized training. The wearer simply puts on the garment as normally would be done, without needing to carefully manipulate it to avoid contamination.

Inventive Principle:

Principle #13The other way round (Inversion)

3Ease of operation

If the outer surface is exposed during donning, then the garment can be easily donned, but the outer surface becomes contaminated

Engineering Contradiction:

Improvedonning easeVSAvoidouter surface contamination

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The sleeve and leg portions are folded underneath the torso portion, creating a nested configuration where the outer surface is contained within the folded structure. This nesting allows the garment to be donned easily while the outer surface remains protected from exposure and contamination.

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

A packaged garment includes a garment and a sealed bag. The garment has a torso portion, a sleeve portion connected to the torso portion, and a leg portion connected to the torso portion. The garment has an outer surface and an inner surface opposite the outer surface. The sealed bag contains the garment with the sleeve portion folded onto the torso portion, a portion of the sleeve portion folded at least once underneath the sleeve portion between the sleeve portion and the torso portion, and the leg portion folded onto the torso portion. The garment is manipulated so that the inner surface of the torso portion faces outward and the torso portion forms an inner space containing the sleeve portion and the leg portion.
