Absorbent Article Test Strip Covering for Clear Pre-Use Readability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing absorbent articles with testing members for health conditions have issues with erroneous recognition before use due to the labeled antibody being visibly colored, leading to confusion about whether a color developing reaction has occurred.
Innovation Solution
The absorbent article includes a movement portion with a colored antibody that causes an antigen-antibody reaction, an indicator portion that develops color based on the reaction, and a colored region covering the antibody, preventing visibility before use, while ensuring clear visibility after use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the labeled antibody is colored to enhance visibility after color developing reaction, then the indicator portion becomes more noticeable, but the wearer may erroneously perceive the testing member before use as the testing member after use
Solution Approach 1:
The testing member is divided into distinct functional regions: the movement portion containing the colored antibody and the indicator portion where color development occurs. This segmentation allows the colored antibody to be hidden from view while still enabling the indicator to display results clearly, resolving the contradiction between visibility and misinterpretation risk
Solution Approach 2:
The patent introduces a cover structure that acts as an intermediary between the colored antibody and the wearer's view. This cover hides the colored antibody before use, preventing erroneous perception, while allowing the indicator portion to remain visible for result detection, thus resolving the visibility-reliability contradiction
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
Prevents erroneous recognition before use by concealing the colored antibody, allowing for accurate and easy detection of the testing result after use, with enhanced visibility and reduced mental burden.
Implementation Method 1
The movement portion includes a labeled antibody that causes an antigen-antibody reaction with the excreta component
Implementation Method 2
The indicator portion develops color by capturing at least one of a complex formed by causing the antigen-antibody reaction and the labeled antibody

AI summary
The present invention provides an absorbent article capable of preventing erroneous recognition of the testing member before use of the absorbent article. The absorbent article (1) includes a testing member (60) for testing a health condition of a wearer. The testing member includes a movement portion (66) that allows an excreta component as a component contained in excreta to move, and an indicator portion (62) that develops color based on the excreta component guided from the movement portion (66). The movement portion (66) includes a labeled antibody that causes an antigen-antibody reaction with the excreta component. The labeled antibody includes a colored antibody that has been colored. The indicator portion develops color by capturing at least one of a complex formed by causing the antigen-antibody reaction and the labeled antibody. The absorbent article includes a colored region (R20) that covers a skin side of the colored antibody disposed in the movement portion.
