Absorbent Article V-Shaped End Groove for Body Contouring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing absorbent articles face challenges in providing a comfortable fit along the curvature of the human body, particularly in the end regions, due to insufficient fitting and potential discomfort caused by protrusions against the skin.
Innovation Solution
The design incorporates a main body with a liquid-permeable topsheet, a liquid-impermeable backsheet, and an absorbent core, featuring a V-shaped end region compressed groove that allows for easy curvature and deformation, along with front-rear direction compressed grooves extending beyond the V-shape tip to facilitate a snug fit and prevent excessive rigidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If linear compressed grooves are formed in the absorbent article main body to control fluid transfer and deform the article to follow body shape, then the article can maintain structural integrity and provide basic fit, but the end region cannot sufficiently follow the roundness of the human body
Solution Approach 1:
The compressed groove pattern is segmented into different regions: a first circular groove in the end region and front-rear direction compressed grooves in the middle region. This segmentation allows the end region to be independently shaped to follow body roundness while the middle region maintains fluid transfer control, resolving the contradiction between adaptability and shape control.
Solution Approach 2:
A first circular groove is formed in the end region of the absorbent article main body. This curved geometry enables the end region to conform to the roundness of the human body, directly improving the ability to follow body curvature without compromising the overall structural integrity provided by the linear compressed grooves.
2Ease of operation
If the front compressed groove is bent at a depressed portion to reduce longitudinal wrinkles, then wrinkle formation is reduced, but the protruded portion may abut against the skin causing discomfort
Solution Approach 1:
The harmful protruded portion is extracted or eliminated by forming a circular groove pattern instead of bending a linear groove. The circular groove configuration avoids creating protrusions that would abut against the skin, while still allowing the material to deform and reduce wrinkles through the curved geometry.
Solution Approach 2:
The compressed groove structure is redesigned to convert the potential harm of rigid protrusions into the benefit of a flexible circular pattern. The circular groove allows controlled deformation that reduces wrinkles while the rounded geometry ensures any deformation is comfortable against the skin, transforming a harmful effect into a beneficial one.

AI summary
In an absorbent article having an elongate shaped main body with compressed grooves, the compressed grooves include: a pair of front-rear direction compressed grooves extending in a front-rear direction; and an end region compressed groove formed in at least one of a front end region and a rear end region, and having a shape including a substantial V-shape projecting toward a middle region. The front-rear compressed grooves extend beyond the tip of the end region compressed groove in a direction away from a body fluid discharge opening corresponding region.
