Extensible Body-Adhering Absorbent Shell Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional absorbent personal care articles are uncomfortable to wear, prone to leakage, and lack discretion due to poor fit and adhesive issues, with visible silhouettes and discomfort caused by adhesive exposure and movement-induced bunching.
Innovation Solution
A disposable personal care article featuring a shell with body-adhering properties, including a silicone material and extensible design, providing a snug and discreet fit with minimal gaps through strategic attachment means and absorbent structure configuration, allowing for comfortable wear and effective fluid management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive is applied to the body-facing surface of the topsheet to adhere the absorbent article to the skin, then the article can be attached to the wearer's body, but the shape and size remain the same as articles attached to undergarment causing discomfort
Solution Approach 1:
The patent modifies the physical parameters of the absorbent article by making it extensible and contoured to match body curves. The article transitions from a flat, rigid structure to a flexible, body-adapting form that can stretch and conform to the wearer's anatomy, thereby improving comfort while maintaining secure attachment
2Reliability
If the adhering portion comes into contact with hair in the region, then the article can adhere to the body, but removal becomes excruciatingly painful
Solution Approach 1:
The patent employs a flexible, thin-film structure that can conform to body contours without creating excessive tension. This flexibility allows the article to adhere securely to the body while enabling painless removal, as the material can stretch and adapt rather than pulling on hair and skin
3Reliability
If absorbent article is attached to underwear or undergarment, then the article can be secured in place, but movement of the body causes bunching or twisting leading to discomfort and poor fit
Solution Approach 1:
The patent transforms the static, rigid attachment system into a dynamic one where the absorbent article can move and deform with the wearer's body. The extensible and contoured design allows the article to adapt to body movements in real-time, maintaining proper fit and comfort throughout various activities without bunching or twisting
4Reliability
If conventional absorbent article design is used, then the article can provide basic absorbency, but the silhouette is visible through clothing compromising discretion
Solution Approach 1:
The patent modifies the dimensional parameters of the absorbent article by creating a thinner, more contoured profile that adapts to body curves. This reduced bulk and improved shaping allow the article to remain discreet under clothing while preserving its absorbent functionality through optimized material distribution
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 article offers a comfortable, discreet, and secure fit with reduced leakage risk, adapting to various movements and body shapes, while minimizing adhesive exposure and visibility issues.
Implementation Method 1
the first area comprises a body attachment means for adhering the shell directly to the skin and/or hair of the wearer
Implementation Method 2
the shell has an anterior portion and a posterior portion, wherein the posterior portion exhibits a higher extension relative to the anterior portion when a stretching force of 454 grams is applied
