Urethral Support Cushion Redirecting Abdominal Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for urinary stress incontinence in women are inadequate, with existing devices either ineffective, uncomfortable, or associated with high complication rates, and most women resort to using absorbent diapers due to the lack of effective solutions.
Innovation Solution
A directional device providing partial and posterior support to the urethra using a rigid rectangular cushion with adjustable straps, redirecting abdominal pressure forces to facilitate urethral flexion and closure, integrated into briefs for comfort and practicality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid rectangular cushion with straps is used to support the urethra, then the urethra is effectively occluded during abdominal efforts, but the device may cause discomfort or restriction of movement
Solution Approach 1:
The device provides localized support only to the posterior perineal area where the urethra is located, rather than restricting the entire perineum. The rigid cushion is positioned specifically to support the urethra while the rest of the perineal tissues remain free to move, achieving effective occlusion without excessive restriction of mobility.
Solution Approach 2:
The device is divided into distinct components: a rigid rectangular cushion for urethral support, adjustable straps for positioning, and integration with briefs for comfort. This segmentation allows each component to be optimized for its specific function while maintaining overall comfort and adjustability.
2Reliability
If abdominal pressure forces are redirected forward to create functional plicature, then urinary incontinence is treated, but the device must be precisely positioned to achieve the correct force redirection
Solution Approach 1:
The device incorporates adjustable straps that allow dynamic positioning of the rigid cushion. The straps can be adjusted to accommodate different anatomical variations and ensure optimal positioning for force redirection, making the device adaptable rather than fixed, thus reducing the complexity of achieving precise positioning.
Solution Approach 2:
The device is designed to be self-adjusting through the strap mechanism, allowing the user to position the rigid cushion appropriately without requiring complex external adjustment devices. The straps provide a simple yet effective means of securing the cushion in the correct position for force redirection.
3Reliability
If the device covers the entire perineum to provide support, then prolapse displacement is prevented, but the device becomes wide and bears on the labia majora causing discomfort
Solution Approach 1:
The rigid cushion is designed to cover only the posterior perineal area where the urethra and bladder neck are located, rather than the entire perineum. This localized approach provides necessary support for incontinence treatment while avoiding contact with the labia majora, thereby maintaining comfort and wearability.
Solution Approach 2:
The device extracts the support function from the entire perineal area and concentrates it specifically on the posterior perineum where it is most needed for urethral support. This extraction allows the rest of the perineum, including the labia majora, to remain free and comfortable without unnecessary support structures.
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 device effectively occludes the urethra during abdominal efforts, reducing leakage and promoting healing of urinary stress incontinence while maintaining mobility of other pelvic tissues, offering a comfortable and adjustable solution.
Implementation Method 1
The abdominal forces are not directed vertically to the pelvic floor. They are reflected from the bone surface and muscle structure of the small pelvis. These forces are physically redirected forward.
Implementation Method 2
Friction between tissues bonded together is retained by the young connective tissue.
Implementation Method 3
The plicature of the organs creates areas called 'functional' areas. These areas obstruct leakage.

AI summary
Device for external directional support of the female urethra under stress, consisting of a rigid cushion (1) fixed to a rigid counter-support (2) placed in the rear part of a belt or briefs, and comprising a partial rear perineal support part, the rigid counter-support (2) being connected at the front by adjustable straps (2) supporting it to a belt (5) or briefs whose rear periphery is rigidified by an insert or other non-folding material.
