Solution Overview

Problem

Existing swimwear and undergarments do not effectively prevent the leakage of bodily fluids such as urine and menstrual fluid into aquatic environments, causing embarrassment and unhygienic conditions.

Innovation Solution

A garment component with a liquid impermeable base layer, peripheral layer, and functional layer that forms a sealing engagement with the skin to trap bodily fluids, incorporating a wicking element to manage moisture and an absorbent element to collect fluids, while being breathable and washable.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional swimwear and undergarments are used, then the garment allows freedom of movement and breathability, but bodily fluids can leak into the aquatic environment causing embarrassment and unhygienic conditions

Engineering Contradiction:
Improvefluid containment reliabilityVSAvoidgarment structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The garment is divided into distinct functional layers: a liquid permeable outer layer for breathability, a liquid impermeable intermediate layer for fluid containment, and a liquid absorbent inner layer for fluid collection. This segmentation allows each layer to perform its specific function while working together to prevent leakage.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The garment utilizes composite construction by combining multiple materials with different properties - the outer layer uses breathable fabric, the intermediate layer uses waterproof material, and the inner layer uses absorbent material. This composite approach enables the garment to simultaneously achieve breathability, fluid containment, and absorption.

Inventive Principle:
Principle #40Composite materials

2Reliability

If liquid impermeable barrier layers and seals are added to prevent fluid leakage, then fluid containment improves, but the garment becomes less breathable and more difficult to wash

Engineering Contradiction:
Improvefluid containment reliabilityVSAvoidgarment manufacturing complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The barrier function is segmented into a specific intermediate layer rather than being integrated throughout the entire garment. This allows the barrier layer to be positioned strategically where fluid containment is needed while leaving other areas breathable and easy to manufacture.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The liquid impermeable barrier is applied locally at the crotch and groin areas where fluid leakage is most likely to occur, rather than making the entire garment waterproof. This localized approach maintains breathability in other areas while providing containment where needed.

Inventive Principle:
Principle #3Local quality

3Reliability

If absorbent materials are used to collect bodily fluids, then fluid management improves, but the garment becomes heavier and less breathable

Engineering Contradiction:
Improvefluid management effectivenessVSAvoidgarment weight
Core Design Contradiction:
ReliabilityVSWeight of moving object

Solution Approach 1:

The absorbent material is concentrated in the inner layer at the crotch and groin areas where bodily fluids are generated, rather than distributing absorbent material throughout the entire garment. This localized placement provides effective fluid management while minimizing overall weight.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The absorbent function is segmented into a dedicated inner layer that collects fluids, while the outer layers maintain breathability. This segmentation allows the absorbent material to perform its function without compromising the breathability of the entire garment structure.

Inventive Principle:
Principle #1Segmentation

4Reliability

If multiple barrier layers and seals are incorporated to prevent fluid leakage, then leakage prevention improves, but the garment becomes less comfortable and more complex to maintain

Engineering Contradiction:
Improveleakage preventionVSAvoidgarment comfort and maintenance
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The leakage prevention system is segmented into three functional layers that work together: the permeable outer layer allows breathability, the impermeable intermediate layer provides the barrier, and the absorbent inner layer collects fluids. This segmentation achieves leakage prevention while maintaining comfort through breathability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The garment uses composite materials with different properties in each layer - breathable fabric externally, waterproof material in the intermediate layer, and absorbent material internally. This composite construction provides leakage prevention while maintaining comfort through the breathable outer layer.

Inventive Principle:
Principle #40Composite materials

AI summary

The present disclosure generally relates to a garment component (100) for use in a garment (200). The garment component (100) comprises: a liquid impermeable base layer (110); a liquid impermeable peripheral layer (120) disposed along a periphery of the liquid impermeable base layer (110); and a space (130) defined by the liquid impermeable base and peripheral layers (110,120). When the garment (200) comprising the garment component (100) is worn on a user, the garment (200) forms a sealing engagement between the liquid impermeable peripheral layer (120) and the user's skin (300), such that the liquid impermeable base and peripheral layers (110,120) prevent liquid flow into and out of the space (130) and the space (130) collects bodily fluids from the user.
