Disposable Garment Elastication Zones for Contour Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Disposable absorbent garments lack optimal contour support and fit, particularly in the abdomen and rear regions, due to inadequate distribution of elastication and non-elastication zones.
Innovation Solution
Incorporating multiple elasticated areas in the waist, abdomen, buttocks, leg openings, and crotch areas, with specific configurations of elastic strands or films, and strategically placing de-elasticated regions to enhance fit and prevent leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If zones of elastication are incorporated in the garment, then contour support and fit are improved, but the garment complexity increases
Solution Approach 1:
The garment is divided into distinct zones of elastication and non-elastication in the front and rear panels. This segmentation allows different regions to provide different functional properties - elasticated zones for contour support and non-elasticated zones for simplicity, thereby improving fit while managing complexity through functional zoning.
Solution Approach 2:
Different regions of the garment are assigned different elastic properties - some areas have elastication while others have non-elastication. This local differentiation optimizes the fit and contour support in specific areas (waist, abdomen, rear) without requiring the entire garment to be complex, addressing the contradiction between improved shape and reduced overall complexity.
2Adaptability or versatility
If multiple elasticated areas are added to enhance fit, then the garment's ability to mimic regular underpants improves, but manufacturing complexity increases
Solution Approach 1:
The garment structure is segmented into multiple elasticated areas (waist, abdomen, rear, leg openings, crotch) and non-elasticated areas. This segmentation enables the garment to adapt to various body contours like regular underpants while allowing manufacturers to produce different zones separately or with different processes, managing manufacturing complexity through modular design.
Solution Approach 2:
The garment incorporates multiple elasticated areas that serve different functions - waist elastics for waistband fit, leg elastics for leg opening fit, crotch elastics for crotch contour support. This multi-functionality allows a single garment design to mimic regular underpants in multiple ways, enhancing adaptability while the standardized elastic components maintain ease of manufacture.
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 solution provides improved contour support and fit by distributing elastication and non-elastication zones effectively, enhancing the garment's ability to mimic regular underpants and prevent leakage.
Implementation Method 1
Elasticated areas may result from the inclusion of elastic strands, elastic film, or other elasticizing means known in the art
Implementation Method 2
Disposable absorbent garments are designed to be put on and taken off in the same manner by which regular underpants are put on and taken off... receive and contain urine and other bodily wastes

AI summary
A disposable absorbent garment includes front and rear panels with zones of elastification and non-elastication in the abdomen and rear regions of the garments. The zones of elastification comprise an elastified region, and a non-elastified region or a de-elastified region. The elastified non-elastified or de-elastified regions work in tandem to provide greater contour support and improved fit.
