Garment Fluid Retention Assembly with Interior Bonding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional garments with absorbent regions are often bulky and difficult to conceal, and their attachment methods can lead to leakage and bulkiness, compromising comfort and discreetness.
Innovation Solution
The development of garments with two or more fluid-retention zones of varying absorbencies, where the fluid retention assembly is bonded only to the interior side of the garment base, avoiding exterior bonding or stitching to maintain discreetness and aesthetic appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If absorbent regions are bonded through the main body portion of the garment, then leak protection is improved, but the garment becomes bulky and the absorbent regions become visible on the exterior
Solution Approach 1:
The bonding is segmented into two distinct regions: internal bonds that extend through the entire garment thickness for leak protection, and external bonds that are limited to the interior surface to avoid bulkiness and visibility. This segmentation allows each bonding region to serve its specific function optimally.
Solution Approach 2:
Different bonding characteristics are applied to different locations within the garment. The internal bonds provide through-and-through attachment for reliability, while the external bonds provide surface-level attachment only where needed for structural support, creating local variations in bonding quality that resolve the contradiction.
2Strength
If absorbent regions are bonded through the main body portion of the garment, then attachment strength is improved, but the garment loses discreetness and aesthetic appeal
Solution Approach 1:
The bonding structure is divided into internal and external components with different functions. Internal bonds provide the necessary attachment strength through the garment layers, while external bonds are restricted to the interior surface, ensuring that no bonding elements are visible from the exterior, thus preserving discreetness.
Solution Approach 2:
The internal bonds act as intermediaries that transfer the attachment function from the visible exterior to the hidden interior. By moving the bonding action to the interior surface, the garment exterior remains smooth and discreet while still achieving strong attachment through the layered bonding structure.
3Ease of manufacture
If uniform absorbency is used throughout the garment, then manufacturing simplicity is maintained, but overall absorbency efficiency is reduced
Solution Approach 1:
The absorbent material is configured with varying absorbency characteristics in different zones of the garment. High-absorbency regions are positioned where fluid contact is most likely, while lower-absorbency regions are used in areas with less fluid exposure. This local differentiation increases overall absorbency efficiency while maintaining a relatively simple manufacturing process.
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
This design enhances overall absorbency while minimizing bulkiness, providing effective leak protection and maintaining the garment's discreet and comfortable nature.
Implementation Method 1
a moisture-impermeable layer configured to restrict fluid from exiting the fluid retention assembly to an exterior side of the garment base
Implementation Method 2
a first fluid-retention zone configured to absorb fluid excreted from the wearer when the garment is worn by the wearer

AI summary
Garments include a fluid retention assembly coupled to an interior side of a garment base, with said coupling not being present on an exterior side of the garment base. The fluid retention assembly includes two fluid-retention zones of different absorbencies. One or more fluid retention assemblies may be located anywhere on the garment, without being limited to positioning near edges or apertures. A moisture-impermeable layer of the fluid retention assembly separates the interior side of the garment base from the fluid retention zones, such that the moisture-impermeable layer is configured to restrict and/or at least substantially prevent fluid from exiting the fluid retention assembly to the exterior side of the garment base.
