Absorbent Article Leakage Warning Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Absorbent articles, such as feminine care products and incontinence products, lack a mechanism to notify wearers when they are nearing fullness, leading to potential leakage, which can be embarrassing and inconvenient, especially in public settings.
Innovation Solution
Incorporating a leakage warning element within the absorbent article that provides a distinct physical sensation, such as temperature change, pressure change, or foaming, when the article is nearing fullness, allowing the wearer to recognize the need for replacement before leakage occurs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the absorbent article is designed to quickly absorb and retain body exudates, then wearer dryness and comfort are improved, but the wearer's ability to notice when the article is becoming full is reduced
Solution Approach 1:
The patent implements a feedback mechanism through a leakage warning element that provides tactile feedback to the wearer when the absorbent article reaches fullness. The warning element consists of a warning material layer that becomes pliable when contacted by body exudates, creating a noticeable sensation against the wearer's skin to indicate fullness.
Solution Approach 2:
The patent employs a visual indication mechanism where the warning material changes its physical properties (becomes pliable) upon contact with body exudates. This physical state change serves as a visual and tactile signal to the wearer, analogous to color change indicators, to communicate the fullness status of the absorbent article.
2Device complexity
If the absorbent article provides no leakage warning mechanism, then the device complexity is reduced, but the risk of leakage increases
Solution Approach 1:
The patent implements preliminary action by placing the leakage warning element in strategic positions within the absorbent article structure, specifically between the bodyside liner and the absorbent core. This positioning allows the warning element to detect fullness before leakage occurs, providing advance notice to the wearer to change the article.
Solution Approach 2:
The warning material acts as an intermediary between the absorbent core and the bodyside liner. When body exudates reach the warning material, it becomes pliable and transmits this tactile signal through the bodyside liner to the wearer's skin, serving as a mediator that communicates fullness status without requiring complex electronic or mechanical systems.
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 leakage warning element effectively alerts the wearer to the article's fullness, reducing the risk of accidental leakage and enhancing comfort and convenience by providing timely notification of the need to change the article.
Implementation Method 1
the leakage warning element is adapted to provide a physical sensation indicating a fullness level of the absorbent assembly
Implementation Method 2
the leakage warning element is adapted to impart a physical sensation to the wearer
Implementation Method 3
such as temperature change, pressure change, or foaming
