Reusable Absorbent Pant Structure With Removable Leak-Control Insert
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing absorbent products, particularly durable reusable ones, suffer from insufficient capacity and fluid handling performance, leading to leakage during all-day wear due to poor fit or improper placement, resulting in soiling of clothing or bedding.
Innovation Solution
A durable absorbent pant designed with a knitted or woven structure, incorporating a gusset with a wearer-facing liquid permeable top layer, a durable absorbent layer, and a liquid impermeable barrier layer, forming an enveloping structure to accommodate removable absorbent inserts, along with containment barriers to minimize leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a disposable absorbent pant is used, then hygiene and convenience are improved, but environmental pollution and waste increase
Solution Approach 1:
The absorbent pant is divided into two separate components: a reusable outer pant and a disposable absorbent insert. The outer pant can be washed and reused multiple times, while only the absorbent insert is discarded after use. This segmentation reduces overall waste compared to disposing of entire pants, while maintaining the hygiene benefits of disposables.
Solution Approach 2:
The absorbent insert is extracted as a separate removable component from the outer pant. This allows the insert to be replaced independently without discarding the reusable outer pant, separating the disposable functional element from the reusable structural element.
2Object-generated harmful factors
If a reusable absorbent pant is used, then environmental pollution is reduced, but absorbency and leak protection deteriorate
Solution Approach 1:
By separating the pant into reusable outer and disposable insert components, the system allows the outer pant to be environmentally friendly and reusable, while the insert provides reliable absorbency performance that can be replaced when depleted or soiled.
Solution Approach 2:
The absorbent insert uses superabsorbent polymer materials that can absorb and retain large amounts of liquid, providing superior absorbency parameters compared to traditional reusable fabrics, while the outer pant maintains structural integrity and leak protection features.
3Ease of manufacture
If traditional absorbent materials are used, then cost is reduced, but absorbency and retention capacity decrease
Solution Approach 1:
The absorbent insert incorporates superabsorbent polymers that dramatically increase liquid absorption and retention capacity compared to traditional materials. These materials can absorb hundreds of times their weight in liquid, providing superior performance while being manufactured as a disposable component to control costs.
Solution Approach 2:
The absorbent insert uses composite materials including superabsorbent polymers combined with other absorbent layers and distribution layers, creating a multi-layer structure that optimizes both absorbency performance and cost-effectiveness through the strategic use of different material properties.
4Adaptability or versatility
If the absorbent pant is made to fit various body shapes, then adaptability is improved, but manufacturing precision and fit quality worsen
Solution Approach 1:
The outer pant incorporates elastic waistbands and stretchable materials that dynamically adapt to different body shapes and sizes. The elastic components provide flexibility and conformability, allowing the pant to accommodate various anatomies while maintaining secure fit and preventing leakage.
