Disposable Penile Sheath with Absorbent Interior for Urine Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sheaths do not effectively address urinary incontinence after voluntary urination and lack a method for disposing of the sheath after use.
Innovation Solution
A disposable penile sheath with an elongated receptacle having a liquid-impermeable exterior and absorbent interior, secured by an elastic band, allowing for voluntary urination containment and easy disposal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional condom-style sheath is used, then it can be worn during voluntary urination, but it cannot effectively contain urinary incontinence after urination is complete
Solution Approach 1:
The patent employs a disposable sheath that is discarded after a single use. The sheath is designed to be used once for containing urinary incontinence after voluntary urination, then disposed of in the trash. This eliminates the need for complex cleaning and sterilization processes, making the device simple to operate and dispose of while maintaining reliable urine containment during its service period.
2Ease of operation
If a reusable sheath is used, then it can be cleaned and sterilized for repeated use, but it creates complexity in cleaning and sterilization procedures
Solution Approach 1:
The patent employs a disposable sheath that is discarded after a single use. The sheath is designed to be used once for containing urinary incontinence after voluntary urination, then disposed of in the trash. This eliminates the need for complex cleaning and sterilization processes, making the device simple to operate and dispose of while maintaining reliable urine containment during its service period.
3Adaptability or versatility
If a sheath designed for voluntary urination is used, then it allows urination through the penis, but it fails to contain urine after urination is complete
Solution Approach 1:
The sheath incorporates an absorbent material specifically positioned at the distal end to address urinary incontinence after voluntary urination. This localized absorbent region provides different functionality at different locations within the sheath, allowing it to both permit voluntary urination and subsequently contain any incontinence that occurs.
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
Effectively contains urine after voluntary urination and facilitates easy removal and disposal of the sheath, providing a practical solution for urinary incontinence management.
Implementation Method 1
The interior layer comprises an absorbent material
Implementation Method 2
The interior layer comprises an absorbent material normally comprising a tissue paper
Implementation Method 3
The exterior layer comprises a liquid impermeable material such as rubber
Implementation Method 4
An elastic band may be coupled to the receptacle and extend around the opening

AI summary
A method for using a disposable penile sheath for containing urinary incontinence after voluntary urination includes the steps of urinating voluntarily through a penis and providing a receptacle thereafter. The penis inserts through an opening into the receptacle wherein the receptacle contains urinary incontinence after voluntary urination. The penis is removed from the opening of the receptacle and the receptacle is disposed of thereafter.
