Bowl-Shaped Absorbent Core for Male Pant Diaper Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disposable pant-type absorbent articles for male users face challenges in providing optimal comfort and leakage protection, as they are not adequately adapted to the user's anatomy, leading to suboptimal sealing and containment of urine.
Innovation Solution
A disposable pant-type absorbent article featuring a bowl-shaped portion in the front region, formed by a combination of elastic elements that press the absorbent core towards the user and allow it to bulge outwardly, with side elastic elements creating a gathering effect to enhance sealing and containment, thereby improving comfort and leakage protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the absorbent article uses a conventional flat design, then the manufacturing process is simple, but the article does not adapt well to male anatomy resulting in poor leakage protection
Solution Approach 1:
The patent introduces a bowl-shaped portion in the front region of the absorbent article, creating a curved three-dimensional structure that adapts to male genital anatomy. This curvature allows the side edges of the absorbent core to better contact the skin contour, improving sealing and leakage protection while maintaining manufacturing feasibility through elastic gathering techniques.
2Ease of operation
If the absorbent article uses a bowl-shaped portion to adapt to male anatomy, then leakage protection and comfort are improved, but the manufacturing process becomes more complex
Solution Approach 1:
The patent utilizes elastic elements that change their physical state during manufacturing and use. The elastic gathering elements are attached in a stretched state during manufacturing, creating the bowl shape, and then relax to provide continuous gathering force during use. This parameter change approach allows the complex three-dimensional shape to be formed through material properties rather than complex molding processes.
3Adaptability or versatility
If elastic elements are used to form the bowl-shaped portion, then the article adapts better to user anatomy, but the device structure becomes more complex
Solution Approach 1:
The patent divides the elastic gathering function into multiple discrete elastic elements distributed around the front region. Rather than using a single complex mechanism, multiple simpler elastic elements work together to create the overall bowl shape and gathering effect, making the system more adaptable and easier to manufacture.
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 bowl-shaped design enhances user comfort and leakage protection by better adapting to the user's anatomy, ensuring improved sealing and controlled urine flow, thus providing a more secure and comfortable wear experience.
Implementation Method 1
a first portion of a plurality of elastic threads extending continuously over a central portion of the absorbent article for pressing a front portion of the absorbent core towards a user during use of the absorbent article, and a second portion of the plurality of elastic threads located more towards a back than the first portion includes at least one elastic thread extending on the transverse sides of the front region but not completely over the front region
Implementation Method 2
at least one elongated side elastic element attached in a substantially longitudinal direction on each transverse side of the front region for providing a side gathering effect along the transverse sides of the front region. The gathering effect along the sides of the front region serves to contract the absorbent core in the front region in the longitudinal direction, such that absorbent core in the front region bulges outwardly
