Magnetic Urination Control Device for Incontinence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional urination control devices lack reliability, safety, and comfort, and are often complex, leading to issues such as incomplete prevention of urinary incontinence, contamination risks, and incompatibility with both men and women, with existing solutions requiring invasive procedures or cumbersome materials.
Innovation Solution
A urination control device comprising a conduit with upstream and downstream restraint members and a control member that uses magnetic forces to block or allow urine flow based on intravesical pressure, allowing for adjustable and secure urination control without the need for external manipulation, featuring a simple structure and safe materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional urination control devices are used, then urination control function is provided, but reliability and safety are insufficient
Solution Approach 1:
The device is divided into three functional segments: upstream restraint member with through hole, control member that blocks the hole, and downstream restraint member. This segmentation allows each component to perform its specific function reliably while keeping the overall structure manageable and safe.
Solution Approach 2:
The patent replaces complex mechanical switching mechanisms with a magnetic field-based control system. The control member is attracted to or repelled from the upstream restraint member by magnetic forces generated by a magnet, eliminating the need for complex mechanical linkages and improving both reliability and safety.
2Reliability
If conventional devices with valves and catheters are used, then urination control is achieved, but contamination risks increase
Solution Approach 1:
The patent extracts and eliminates the catheter component from the urination control mechanism. Instead of using a catheter that requires insertion and manipulation, the device uses a magnetic field to control the blocking member, thereby removing the source of contamination associated with catheter-based systems.
Solution Approach 2:
By replacing mechanical catheter manipulation with magnetic field control, the system eliminates the need for physical insertion and adjustment of catheters, significantly reducing the risk of infection and contamination while maintaining effective urination control.
3Object-affected harmful factors
If passive measures like napkins and urine-collecting bags are used, then urinary incontinence is managed, but quality of life deteriorates due to unpleasant sensation and odor
Solution Approach 1:
The device enables the patient's body to control urination autonomously through magnetic field activation. The magnetic attracting member responds to magnetic fields to open or close the through hole, allowing the patient to control urination without external assistance from napkins, bags, or other passive management tools, thereby significantly improving quality of life and comfort.
4Reliability
If invasive surgical procedures are performed, then pelvic floor muscle disturbance is corrected, but physical pain and surgical risks occur
Solution Approach 1:
The patent replaces invasive surgical intervention with a non-invasive magnetic field-based control system. The magnetic attracting member can be activated remotely using a magnet, eliminating the need for surgical procedures to correct pelvic floor muscle disturbance, thereby curing urinary incontinence without causing physical pain or surgical complications.
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 enables autonomous and accurate urination control, preventing incontinence while minimizing infection risks and being applicable to both men and women, improving quality of life by eliminating the need for external aids like napkins and reducing odor issues.
Implementation Method 1
the control member and the upstream restraint member are magnetically attracted to each other, the control member blocks the through hole opening of the upstream restraint member

AI summary
A urination control device includes a conduit to be inserted into the urethra, an upstream restraint member located upstream of the conduit and having a through hole, a control member located on the downstream side from the upstream restraint member in the conduit, and a downstream restraint member located on the downstream side from the control member in the conduit, wherein the upper restraint member and control member attract each other with magnetic force, and the control member is brought in contact with the opening portion of the through hole in the upstream restraint member at least in the state exerting no fluid pressure on the upstream side so as to block passage of fluid through the upstream restraint member and admit the passage of fluid through the downstream restraint member in the state engaged with the control member.
