Containment Pant Attachment Mechanism for Leakage Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Disposable absorbent garments for bedwetting are not satisfactory for users who prefer a product that looks and feels like conventional underwear while still providing effective urine containment.
Innovation Solution
A permanently closed containment pant with a fluid-impervious pouch and elastic transitions, designed to resemble conventional underwear, featuring a durable outer chassis and a securely attached absorbent insert to minimize leakage and enhance comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If disposable absorbent garments are designed to be more underwear-like with softer materials and gender-specific graphics, then user satisfaction and aesthetic appeal are improved, but the product still looks and feels like a diaper to many users
Solution Approach 1:
The containment pant is divided into distinct functional segments: an outer chassis that resembles conventional underwear and an inner absorbent sling that provides containment functionality. This segmentation allows each part to optimize its specific function while the whole achieves both aesthetic appeal and effectiveness.
Solution Approach 2:
The absorbent functionality is extracted into a separate removable insert that can be placed within the underwear-like chassis. This extraction allows the outer garment to maintain a conventional underwear appearance while the inner insert provides the necessary absorbent capabilities.
2Reliability
If the sling is securely attached to the chassis to prevent leakage, then containment reliability is improved, but the garment loses flexibility and comfort
Solution Approach 1:
The attachment mechanism uses elastic materials that dynamically adjust to the wearer's movements and body shape. The elastics provide continuous attachment force while allowing range of motion, maintaining both containment reliability and flexibility throughout the day.
Solution Approach 2:
The attachment system utilizes elastic materials with specific stretch properties that change their physical parameters (length, tension) in response to movement and pressure, allowing the garment to maintain secure attachment while adapting to dynamic wear conditions.
3Ease of operation
If elastic materials are used to attach the sling to the chassis, then flexibility and comfort are improved, but the attachment reliability may be compromised
Solution Approach 1:
The attachment mechanism combines elastic materials with bonded attachment points, creating a composite system where the elastic provides flexibility and the bonded portions provide secure anchoring. This composite approach maintains both flexibility and attachment reliability simultaneously.
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 effective urine containment and comfort, resembling conventional underwear while maintaining the functionality of absorbent garments, thus addressing user preferences and leakage issues.
Implementation Method 1
a first transition and a second transition that are elastically extensible in a longitudinal direction and in a transverse direction
Implementation Method 2
The sling includes a fluid-impervious base sheet and a containment flap joined with the base sheet to create a fluid-impervious pouch

AI summary
A permanently closed containment pant including a chassis and a sling that is positioned within the chassis and is joined to the front waist region and the back waist region is disclosed. The sling is attached to the chassis with an attachment mechanism to secure the sling to the chassis. The attachment mechanism may comprise a bonded attachment and an attachment elastic material at a middle portion of the sling to the chassis at the crotch region; a bond attachment adjacent the pouch in a transition material; or elastics extending from the leg openings and attaching to the sling in the crotch region.
