Absorbent Garment Waistband Softened Material Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional diaper pants with elastic side panels can cause skin irritation due to high tension, leading to discomfort and red markings on the wearer's skin, necessitating a solution for a softer and more comfortable waistband.
Innovation Solution
The absorbent garment features a waistband constructed with a softened material layer between the inner and outer layers, folded over to form the waist edges, with attachment regions that ensure the softened material layer faces the body for enhanced comfort and reduced irritation, while maintaining the elastic properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If elastic strands are used in the side panels to provide high elasticity and conforming fit, then the waistband can accommodate a wide range of body shapes, but the high tension causes skin irritation and red markings
Solution Approach 1:
The patent applies different material properties to different regions of the waistband. The side panels use high-elasticity materials to accommodate body shapes, while the waistband area uses softened, low-tension materials to prevent skin irritation. This local differentiation of material qualities resolves the contradiction between fit adaptability and skin comfort.
Solution Approach 2:
The waistband is segmented into multiple functional zones: elastic side panels for fit accommodation, softened waistband regions for comfort, and attachment regions for structural integrity. This segmentation allows each zone to perform its specific function without compromising the others, enabling both high adaptability and reduced skin irritation.
2Object-affected harmful factors
If a softened material layer is added to the waistband to reduce skin irritation, then skin comfort is improved, but the device complexity increases
Solution Approach 1:
The softened material layer is merged with the existing waistband structure through bonding techniques. Rather than adding a completely separate component, the softening layer is integrated into the waistband assembly, sharing the same structural framework and attachment mechanisms, thereby reducing the increase in device complexity.
Solution Approach 2:
The waistband is constructed as a composite structure combining multiple material layers with different properties: elastic materials for stretch, softened materials for comfort, and bonding materials for attachment. This composite approach allows the waistband to achieve multiple functions simultaneously while maintaining a unified structural design.
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 design provides a custom, soft, and comfortable waistband that reduces skin irritation and maintains the elastic fit, ensuring a more pleasant wear experience.
Implementation Method 1
Both the front panel and the back panel include an elastic area that is disposed between the inner layer and the outer layer
Implementation Method 2
The absorbent garments of the invention have a longitudinal direction and a lateral direction... The folded over portion of the front panel includes a front fold line having a portion of the softened material layer folded over the front fold line

AI summary
An absorbent article (10) includes a longitudinal axis (30) and a lateral axis (32). The absorbent article (10) is a pant that includes a front region (12), a back region (14) and a crotch region (16) disposed between the front region (12) and the back region (14). The crotch region (16) is formed by an absorbent assembly (34). In addition to the absorbent assembly (34), the absorbent article (10) includes a front panel (57) and a back panel (61); the front panel (57) is attached to a front region of the absorbent assembly (34) and the back panel (61) is attached to a back region of the absorbent assembly (34). The front panel (57) and the back panel (61) include a softened material layer (205). The absorbent article (10) has a waistband that provides a custom fit and is soft and comfortable during wear, such that irritation to the skin is reduced or eliminated.
