Male Urinary Incontinence Device With Localized Urethral Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing male urinary incontinence devices are uncomfortable, ineffective for long-term use, and difficult to clean, often constricting blood flow and shifting during use, while also causing skin irritation and bacterial growth due to moisture absorption.
Innovation Solution
A male urinary incontinence device with a circumferential band, dorsal base, and ventral base that applies localized pressure to the urethra without obstructing blood flow, featuring adjustable protuberances and flanges for secure fit and easy cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If uniform bidirectional pressure is applied to close the urethra, then urinary flow is prevented, but blood flow through dorsal arteries and veins is also constricted causing discomfort
Solution Approach 1:
The device applies pressure locally to the urethra through the ventral base and circumferential band while leaving the dorsal region uncompressed. This localized pressure application prevents urinary flow through the urethra without constricting the dorsal arteries and veins, thereby maintaining blood flow and preventing the harmful effects of ischemia and discomfort.
2Duration of action of moving object
If existing incontinence clamps are worn for extended periods, then urinary control is maintained, but discomfort and pain increase making them unusable
Solution Approach 1:
By applying pressure only where needed (ventral urethral region) and avoiding pressure on sensitive areas (dorsal region with blood vessels), the device maintains effectiveness over extended periods without causing the discomfort and pain that limit wear time of conventional clamps.
Solution Approach 2:
The device is divided into distinct components (circumferential band, ventral base, dorsal base) that can be independently optimized. The dorsal base is designed to avoid pressure application, while the ventral base provides targeted urethral compression, allowing long-term comfortable wear.
3Object-affected harmful factors
If fabric components are used to improve comfort, then user comfort increases, but moisture absorption leads to skin irritation and bacterial growth
Solution Approach 1:
The device utilizes a porous backflow preventer valve that allows selective fluid passage while preventing unwanted backflow. The porous structure manages moisture effectively, allowing vapor transmission while preventing bacterial growth, thus maintaining comfort without the harmful effects of moisture accumulation.
Solution Approach 2:
The device employs composite construction with non-fabric materials in moisture-prone areas. The combination of medical-grade materials, porous polymers, and smooth surfaces creates a structure that is comfortable against skin while resistant to moisture absorption and bacterial colonization.
4Adaptability or versatility
If complex multi-component assemblies are used to provide adjustable pressure, then pressure control improves, but cleaning and sanitization become difficult
Solution Approach 1:
The device is segmented into removable components including the circumferential band, ventral base, and backflow preventer valve. This segmentation allows each component to be independently cleaned and sanitized, maintaining adaptability and adjustability while dramatically improving ease of maintenance compared to integrated designs.
Solution Approach 2:
The porous backflow preventer valve and other components are designed with smooth, non-porous surfaces that resist bacterial adhesion and allow easy wiping clean. The porous structure of the valve is engineered to be sanitizeable, maintaining pressure control capabilities while enabling thorough cleaning.
