Absorbent Article Body Conforming Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing absorbent articles face challenges in conforming to the body, particularly in the gluteal cleft area, leading to issues like bunching, twisting, and roping during increased activity.
Innovation Solution
The absorbent article features a fluid intake layer with a rearward-facing arch and lateral stiffeners, along with flexures and a fastening system, to enhance body conformity and maintain intimate contact with the gluteal cleft, reducing movement-related issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a back protection feature is added to conform to the gluteal cleft, then body conformity is improved, but bunching, twisting, and roping occur during increased activity
Solution Approach 1:
The back sheet is divided into multiple regions with different fastening characteristics. The first and second side portions are fastened to the garment, while the central portion remains unfastened. This segmentation allows the sides to be stabilized while the center remains free to conform to body movements, preventing bunching and twisting during activity.
Solution Approach 2:
Different portions of the back sheet have different fastening properties. The side portions are attached to provide structural stability and prevent roping, while the central portion is left unfastened to maintain body conformity and prevent twisting. This local differentiation resolves the contradiction between stability and conformity.
2Reliability
If the pad is secured to prevent movement, then leakage protection is improved, but comfort is reduced due to inability to conform to body contours
Solution Approach 1:
The back sheet is segmented into fastened side portions and an unfastened central portion. The fastened sides provide leakage protection by securing the pad to the garment, while the unfastened center allows the pad to conform to body contours and movements, maintaining comfort during activity.
Solution Approach 2:
The pad has different attachment characteristics in different regions. The sides are secured to the garment for leakage protection, while the central portion remains free to move with the body, ensuring comfort. This local quality differentiation allows simultaneous achievement of protection and comfort.
