Elastomeric Absorbent Articles for Contoured Leak-Resistant Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing absorbent products suffer from leakage due to inconsistent seals at leg and waist openings, causing discomfort and bulkiness, and are often constructed with multiple components that rub against the wearer, leading to mobility issues and embarrassment.
Innovation Solution
Incorporating an elastomeric material and absorbent core between two substrate layers, with breathable and fluid-impervious regions, to provide a smooth contoured fit and securement, reducing leakage and enhancing comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If elastic elements are used around leg and waist openings to hold the garment against the wearer, then securement is improved, but leakage increases due to gapping and inconsistent seal
Solution Approach 1:
The patent combines the elastic securement function and the sealing function into a single integrated elastomeric material layer. This elastomeric layer is positioned between the absorbent core and the outer substrate, simultaneously providing elastic securement to hold the garment against the wearer and a continuous seal to prevent leakage, eliminating the need for separate elastic elements that created gaps.
Solution Approach 2:
The patent employs a composite structure where an elastomeric material is integrated between the absorbent core and the outer substrate. This composite construction allows the garment to have both the elasticity needed for securement and the continuity needed for leakage prevention, as the elastomeric material forms both the elastic component and the sealing barrier in one integrated layer.
2Adaptability or versatility
If multiple components are assembled together to form the absorbent article, then functionality is improved, but discomfort increases from rubbing of overlapping components and seams
Solution Approach 1:
The patent merges multiple functional layers into a more integrated construction. The elastomeric material serves multiple functions simultaneously: it provides elastic securement, creates a continuous seal, and acts as a smooth interface layer between the absorbent core and the outer substrate. This reduces the number of separate components that would otherwise rub against the wearer's skin.
Solution Approach 2:
The elastomeric material forms a flexible, smooth layer that acts as a continuous film between the absorbent core and the outer garment. This thin film structure provides a comfortable interface that eliminates the rubbing and irritation caused by multiple rigid components and seams, while still maintaining all necessary functional properties.
3Reliability
If elastic gatherings are used at openings to hold the garment, then securement is improved, but appearance deteriorates due to bulky appearance
Solution Approach 1:
The patent combines the elastic securement function with a smooth, continuous appearance by integrating the elastomeric material into a unified layer structure. This eliminates the need for separate elastic gatherings that create bulk and visible lines, as the elastomeric material provides securement through its inherent elasticity while maintaining a sleek, contouring appearance.
Solution Approach 2:
The elastomeric material forms a thin, flexible film that conforms to the wearer's body contours without creating bulk. This flexible film structure provides the necessary securement through elastic properties while maintaining a smooth, aesthetically pleasing appearance that contours to the body rather than creating visible gatherings or lines.
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
The elastomeric composite ensures consistent securement and comfort by eliminating gaps and corrugations, improving leak resistance and aesthetics while maintaining a seamless fit.
Implementation Method 1
The elastomeric material can stretch and contract to provide a smooth contoured fit to a wearer
Implementation Method 2
The elastomeric material can include a stretch adhesive

AI summary
The present invention includes disposable absorbent articles, such as disposable undergarment, diapers, other garments, and wound care dressings, having an elastomeric material disposed between two substrate layers and an absorbent core system that disposed on top of or between the two substrate layers. This invention may also include a disposable article having an elastomeric material disposed between two substrate layers without an absorbent core. The inclusion of an stretch adhesive in the construction of the article in various portions of the article (e.g., fastening tabs, front and/or rear sections, entire article, etc.) results in improved securement of the article to a wearer for reducing the risk of leakage and further improving comfort for the wearer. Furthermore, the inclusion of a stretch adhesive can provide a smooth contoured fit to a wearer, thereby improving appearance and self-confidence for the wearer.
