Thin Absorbent Article for Male Anatomy Conformability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing absorbent articles for male urinary incontinence are either too thick and noticeable or too thin and stiff, failing to provide adequate comfort, conformity to the male anatomy, and effective absorption and leak protection.
Innovation Solution
A thin, highly flexible absorbent article with a web-based absorbent core comprising fibrous nonwoven web, cellulose fibers, or a mixture thereof, featuring deformations to enhance conformability and absorption capacity, while maintaining a tapered shape for optimal fit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the absorbent article is made thinner to reduce noticeability, then the article becomes more discreet and comfortable, but the stiffness increases and conformability to male anatomy deteriorates
Solution Approach 1:
The patent applies this principle by using a thin, flexible backsheet and topsheet construction that enables the absorbent article to conform to the contours of male anatomy. The thin film structure provides the necessary flexibility while maintaining structural integrity, allowing the product to be discreet yet adaptable to body shape.
Solution Approach 2:
The patent utilizes parameter changes by adjusting the physical properties of the absorbent core and sheet materials to achieve optimal balance between thickness and flexibility. Through controlled modifications in material density, composition, and structural parameters, the article maintains sufficient flexibility for conformability while providing adequate absorption capacity in a thin profile.
2Volume of moving object
If the absorbent article is made thinner to reduce noticeability, then the article becomes more discreet, but the absorption capacity deteriorates
Solution Approach 1:
The patent applies composite materials by combining multiple material types in the absorbent core construction, including superabsorbent polymers, cellulosic fibers, and synthetic fibers. This composite structure maximizes absorption capacity within a reduced thickness by leveraging the complementary properties of different materials—superabsorbent polymers provide high capacity while cellulosic fibers contribute to fluid distribution and retention.
Solution Approach 2:
The patent utilizes porous materials in the absorbent core and sheet constructions to enhance absorption efficiency. The porous structure increases surface area and capillary action, allowing the thin article to absorb and retain urine effectively despite reduced overall thickness. The porous network enables rapid fluid uptake and distribution throughout the absorbent layers.
3Reliability
If existing male incontinence products are used, then protection against light urine leakage is provided, but the products are thick and noticeable to the user
Solution Approach 1:
The patent applies segmentation by dividing the absorbent article into distinct functional zones and layers, each optimized for specific performance criteria. The segmented construction allows different regions to specialize in absorption, distribution, and containment functions, achieving reliable leak protection while maintaining an overall thin profile that reduces noticeability.
4Reliability
If existing male incontinence products are used, then protection against light urine leakage is provided, but the products are stiff and not able to conform to the male anatomy
Solution Approach 1:
The patent applies this principle by designing the backsheet and topsheet as thin, flexible membranes that can adapt to the contours of male anatomy. These flexible film structures provide the necessary conformability while maintaining structural integrity to ensure reliable leak protection during various body movements and positions.
Solution Approach 2:
The patent utilizes dynamics by creating an absorbent article with flexible, adaptable properties that respond to body movements and anatomical variations. The dynamic design allows the product to maintain its protective function while conforming to different positions and orientations of the male anatomy throughout the day.
