Containment Pant with Elastic Pouch for Bedwetting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current disposable absorbent garments for bedwetting are not satisfactory as they resemble diapers and do not adequately mimic conventional underwear, leading to a need for a product that is both underwear-like and effective in managing bedwetting.
Innovation Solution
A permanently closed containment pant with an elastically extensible chassis and a fluid-impervious pouch system, featuring curved containment flaps and transitions for improved fit and functionality, designed to resemble conventional underwear while providing effective urine management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If disposable absorbent garments are designed to look like conventional underwear, then aesthetic appearance and user acceptance are improved, but the ability to effectively contain and manage urine insults deteriorates
Solution Approach 1:
The invention implements a nested structure where an inner absorbent garment is placed within an outer underwear-like pant. The inner garment contains the absorbent core and containment flaps, while the outer pant provides the conventional underwear appearance. This nesting allows both requirements to coexist - the inner layer handles urine containment reliably while the outer layer provides aesthetic acceptance.
Solution Approach 2:
The invention divides the product into distinct functional segments: an inner absorbent garment with containment features and an outer underwear-like pant. This segmentation allows each component to optimize for its specific function - the inner garment for urine management and the outer pant for appearance - while working together as a complete system.
2Reliability
If containment flaps are made fluid-impervious to prevent leakage, then urine containment reliability is improved, but comfort and breathability deteriorate
Solution Approach 1:
The invention applies local quality by making only specific areas fluid-impervious - namely the containment flaps and critical sealing zones - while leaving other areas of the garment breathable and comfortable. This targeted approach ensures leakage prevention where needed most while maintaining overall comfort and breathability in non-critical areas.
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 containment pant offers a durable, underwear-like solution that effectively manages bedwetting by providing a fluid-impervious pouch system with adjustable tension and a comfortable fit, addressing the dissatisfaction with existing products.
Implementation Method 1
The containment pant includes an elastically extensible chassis and a sling positioned within the chassis. The sling includes a fluid-impervious base sheet and a first containment flap, and a second containment flap each joined with the base sheet to create a fluid-impervious pouch. The first transition and a second transition are elastically extensible in a longitudinal direction and in a transverse direction. In some embodiments, the containment pant has a tension in the longitudinal direction from about 1000 grams force to about 2400 grams force at an elongation of about 150%.

AI summary
A permanently closed containment pant includes an elastically extensible chassis and a sling positioned within the chassis. The sling is joined to the front waist region and the back waist region. The sling includes a fluid-impervious base sheet and a first containment flap, and a second containment flap each joined with the base sheet to create a fluid-impervious pouch. The first end of the first containment flap is joined to the first end of the second containment flap and the second end of the first containment flap is joined to the second end of the second containment flap. The sling also includes a first transition and a second transition that are elastically extensible in a longitudinal direction and in a transverse direction. In some embodiments, the containment pant has a tension in the longitudinal direction from about 1000 grams force to about 2400 grams force at an elongation of about 150 %.
