Solution Overview

Problem

Existing absorbent articles are not effectively adaptable to different types of underwear without compromising absorption capacity or causing spillage, as previous solutions either rely on specific geometric shapes or do not adequately address the need for universal fit.

Innovation Solution

An adjustable absorbent article design featuring an oblong absorbent core with a triangular longitudinal end and an extendable absorbent section that can fold to fit various garment types, combined with a permeable topsheet and fluid-impermeable bottom sheet, allowing for secure attachment and uniform fluid distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single absorbent article design is used, then manufacturing simplicity is maintained, but adaptability to different garment types deteriorates

Engineering Contradiction:
Improveadaptability to different garment typesVSAvoidarticle structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The absorbent article is divided into distinct functional zones: a central absorbent core with triangular longitudinal ends, and lateral absorbent panels that can be independently positioned. This segmentation allows different parts of the article to serve different purposes - the core provides primary absorption while the panels can be folded or extended to match various garment contours, enabling adaptability without requiring multiple complete article designs.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The absorbent panels are designed with flexible attachment mechanisms that allow them to be positioned in multiple configurations. The panels can be folded along with the wings or positioned flat depending on the garment type, providing dynamic adaptability. This dynamic positioning capability allows a single article design to accommodate different garment shapes and sizes without compromising absorption performance.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the absorbent article is made flexible for adjustment, then adaptability improves, but structural stability deteriorates

Engineering Contradiction:
Improveadjustability to garment shapesVSAvoidabsorbent core stability
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The article is segmented into a stable central absorbent core and flexible lateral absorbent panels. The core maintains its oblong shape with triangular longitudinal ends, providing structural stability and consistent absorption capacity. The panels are separately attached and can be independently folded or positioned, providing flexibility for adaptation to different garments without disturbing the core's stable configuration.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different parts of the article have different mechanical properties tailored to their functions. The absorbent core is designed with stable structural characteristics to maintain absorption efficiency, while the lateral panels and wings are designed with greater flexibility to conform to various garment shapes. This local differentiation of mechanical properties allows the article to simultaneously achieve stability where needed and flexibility where required.

AI summary

The present invention relates to an adjustable absorbent article comprising a top sheet, a bottom sheet, an absorbent core located between the top sheet and the bottom sheet, the absorbent core having two longitudinal ends. Said absorbent core has an oblong shape, wherein one of the longitudinal ends has a triangular shape and an absorbent panel overlapped on the periphery of the triangular-shaped longitudinal end of the absorbent core. Said absorbent panel folds to fit different types of garments. Said adjustable absorbent article also comprises an absorbent core with a section corresponding to an absorbent section, which extends from the periphery of the triangular-shaped longitudinal end towards the exterior of the absorbent article, wherein said absorbent section folds to fit different types of garments.
