Absorbent Article Test Indicator for Skin-Side Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing absorbent articles with testing members for health conditions are difficult to visually recognize the testing results from the skin side without removing or peeling off the article, leading to reduced visibility and accuracy.
Innovation Solution
Incorporating hydrophobic parts on both sides of the indicator portion to cover the skin and non-skin sides, allowing the testing result to be visible from the skin side while preventing excreta from directly reaching the indicator, thus maintaining visibility and accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the indicator portion is configured to be seen from the non-skin side, then the testing result can be visually recognized after removing or peeling off the absorbent article, but the testing result is difficult to be visually recognized when the article is worn
Solution Approach 1:
The indicator portion is divided into two separate indicators: a first indicator on the skin side and a second indicator on the non-skin side. This segmentation allows each indicator to serve its specific viewing purpose, resolving the contradiction between visibility when worn versus visibility after removal.
Solution Approach 2:
A transfer member acts as an intermediary between the indicators and the viewing sides. The transfer member includes a first transfer portion that transfers the excreta component to the first indicator and a second transfer portion that transfers it to the second indicator, enabling dual-sided visibility functionality.
2Ease of operation
If the indicator portion is exposed on the skin side for direct visualization, then the testing result is easily visible, but excreta may directly reach the indicator portion and interfere with the testing accuracy
Solution Approach 1:
The transfer member serves as an intermediary between the excreta and the indicator portion. It selectively transfers only the necessary excreta component to the indicator while preventing direct contact between bulk excreta and the indicator, thus maintaining both visibility and testing accuracy.
Solution Approach 2:
The transfer member has different properties in different regions: it is permeable or selective in areas contacting excreta to allow component transfer, but protective in areas near the indicator to prevent direct excreta contact. This local differentiation resolves the contradiction between accessibility and protection.
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
Enables easy and accurate visualization of health condition results without removing the absorbent article, enhancing user convenience and testing precision by guiding excreta components through intended paths and preventing interference from excreta.

AI summary
The present invention provides an absorbent article with which the wearer can easily grasp the testing result. An absorbent article (1) according to one aspect includes a testing member (60) for testing a health condition of the wearer. The testing member (60) includes an indicator portion (62) that develops color based on an excreta component as a component contained in excreta. The absorbent article (1) includes a first hydrophobic part (71) having hydrophobicity that covers a skin side (T1) of the indicator portion (62) of the testing member (60). The indicator portion (62) after color development is visually recognizable from the skin side of the absorbent article.
