Absorbent Sanitary Article with Elastic Gasketing for Open-Pocket Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing absorbent sanitary articles face issues with leakage of semi-solid fecal material from the waist sections due to gasketing elements that remain adherent to the topsheet, preventing the formation of an open pocket for exudate containment.
Innovation Solution
The absorbent sanitary article features a gasketing element with an inner transverse edge detached from the topsheet, forming an open pocket by elastic stretching during wear, and is attached to elastic side panels and leg cuffs to ensure effective containment of exudates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the gasketing element remains adherent to the topsheet surface, then the pocket remains closed, but the gasketing element cannot receive and contain solid or semi-solid exudates
Solution Approach 1:
The gasketing element is designed to be detachable from the topsheet through elastic stretching during wear, transitioning from a closed adherent state to an open detached state that forms a functional pocket for receiving exudates
Solution Approach 2:
The elastic properties of the gasketing element and side panels are utilized to change the geometric configuration from a closed structure to an open pocket structure through stretching deformation
2Ease of operation
If the inner transverse edge of the gasketing element is detached from the topsheet, then an open pocket is formed for receiving exudates, but the gasketing element may not remain in position
Solution Approach 1:
The gasketing element is segmented with only its outer transverse edge attached to the topsheet while the inner transverse edge remains detached, creating a functional pocket structure that is both positioned and open
Solution Approach 2:
The gasketing element is combined with the elastic side panels and leg cuffs to form an integrated containment system that maintains position through elastic stretching while forming an open pocket
3Reliability
If the gasketing element is attached to elastic side panels and leg cuffs, then containment capacity is enhanced, but device complexity increases
Solution Approach 1:
The gasketing element serves multiple functions: it forms the pocket structure, attaches to the topsheet for positioning, connects to side panels for containment, and works with leg cuffs to prevent leakage, reducing the need for separate components
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 ensures an open pocket for receiving and retaining semi-solid exudates, reducing leakage by maintaining the gasketing element detached from the topsheet and enhancing containment capacity.
Implementation Method 1
The side panels may be elastically extensible in the transverse direction... the gasketing element is attached to elastic side panels... capable of being stretched elastically in a transverse direction
