Garment Moisture Capture Assemblies With Bonded Leak Prevention

Solution Overview

Problem

Existing garments with moisture-absorbing properties, such as undergarments, often suffer from bulkiness and leakage issues due to bulky absorbent regions and stitching, compromising comfort and discreetness.

Innovation Solution

A garment with a bonded moisture capture assembly that includes a moisture retention portion and an anti-leak portion, secured by adhesive bonds, allowing for a low-profile and leak-proof design applicable to various garments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If stitching is used to attach absorbent regions to the garment, then the absorbent regions can be securely attached, but leakage occurs through stitching perforations and bulky seams are produced

Engineering Contradiction:

Improveleak-proof propertyVSAvoidleakage through stitching perforations

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent replaces the mechanical stitching system with a bonding system using adhesive material. The adhesive material is applied between the absorbent region and the garment base to create a continuous bond without perforations, thereby eliminating leakage paths while maintaining secure attachment.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent employs a thin film of adhesive material to bond the absorbent region to the garment base. This thin film creates a flexible, continuous barrier that prevents leakage without the need for bulky stitching, achieving both leak-proof properties and comfort.

Inventive Principle:

Principle #30Flexible shells and thin films

2Reliability

If stitching is used to attach absorbent regions to the garment, then the absorbent regions can be securely attached, but bulky seams are produced reducing comfort and discreetness

Engineering Contradiction:

If absorbent regions are made bulky to enhance absorption capacity, then moisture absorption is improved, but comfort and discreetness are compromised

Engineering Contradiction:

Improvemoisture absorption capacityVSAvoidbulkiness of absorbent regions

Core Design Contradiction:

Quantity of substanceVSShape

Solution Approach 1:

The patent employs a thin film of adhesive material to bond the absorbent region to the garment base. This thin film creates a flexible, continuous barrier that prevents leakage without the need for bulky stitching, achieving both leak-proof properties and comfort.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The patent uses composite material construction where the absorbent region is bonded to the garment base using adhesive material. This composite approach allows for a thin, profiled design that maintains absorption capacity while improving comfort and discreetness through the bonding interface.

Inventive Principle:

Principle #40Composite materials

AI summary

Garments comprise a plurality of adhesive bonds within a bonded region of the garment; a garment base that defines a garment lateral edge; and a moisture capture assembly bonded to the garment base within the bonded region. The moisture capture assembly comprises a moisture retention portion configured to absorb and retain moisture; and an anti-leak portion configured to restrict moisture from exiting the moisture retention portion. The bonded region extends fully around a perimeter of the moisture capture assembly, and the moisture capture assembly and the bonded region do not extend to the garment lateral edge.
