Elastic Absorbent Pant Panel for Leakage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current durable absorbent underwear for men with urinary incontinence issues fails to maintain effective contact with the body through various movements, leading to leakage due to the unique anatomy and flow characteristics of urine, and existing products are not designed to handle the male anatomy effectively.
Innovation Solution
A durable absorbent brief pant with an absorbent front panel comprising a combination of layers, including a wearer-facing layer, an absorbent layer, and a liquid impermeable barrier layer, designed to provide elastic stretch capabilities and maintain contact with the body, preventing leakage through various body positions and movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If durable absorbent underwear is designed to maintain contact with the body through body movements, then leakage prevention is improved, but device complexity and comfort are worsened
Solution Approach 1:
The absorbent underwear is divided into multiple functional layers: an elastic base layer that maintains body contact, an absorbent core layer for urine absorption, and an outer protective layer. This segmentation allows each layer to perform its specific function independently, improving leakage prevention without requiring the entire garment to be overly complex
Solution Approach 2:
The patent employs composite material construction by combining elastic materials in the base layer with highly absorbent materials in the core layer. This composite approach enables the garment to simultaneously achieve reliable body contact maintenance and effective urine absorption, resolving the contradiction between reliability and complexity
2Reliability
If durable absorbent underwear is designed to maintain contact with the body through body movements, then leakage prevention is improved, but wearer comfort is worsened
Solution Approach 1:
The elastic properties and absorbent characteristics are concentrated in specific local regions where they are most needed for leakage prevention, rather than uniformly distributed throughout the entire garment. This allows the underwear to maintain reliability in critical areas while preserving comfort in other regions
Solution Approach 2:
The base layer is designed with elastic properties that allow it to dynamically adapt to body movements and changes in body shape. This dynamic adaptation maintains reliable contact during movement while preserving wearer comfort through flexibility and stretch
3Reliability
If absorbent front panel is designed with multiple layers for effective urine interception, then absorbency is improved, but bending properties and flexibility are worsened
Solution Approach 1:
The absorbent front panel utilizes thin-film barrier layers that provide effective urine interception while maintaining flexibility. These thin film structures allow the panel to bend and conform to body movements without compromising its absorbency or creating excessive rigidity
4Reliability
If durable absorbent underwear is designed for male anatomy with varying penis positions, then leakage prevention is improved, but device complexity increases
Solution Approach 1:
The absorbent front panel is designed with a universal structure that can effectively handle urine flow from various penis positions and orientations. The multi-layer construction and elastic properties provide adaptable containment that works across different anatomical configurations without requiring position-specific adjustments or increased complexity
