Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for overactive bladder syndrome, such as medications and electrical stimulation, often come with side effects or require frequent administration, and surgical options carry infection risks, necessitating a method that provides long-term symptom relief without these drawbacks.
Innovation Solution
An electrical stimulation method using a device with a first and second electrode to generate an electric field between 100 V/m to 1000 V/m at a target zone, such as the dorsal root ganglion, to reduce neurotransmission and alleviate symptoms of overactive bladder with minimal side effects and reduced infection risk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If medications are used to treat overactive bladder syndrome, then symptoms are relieved, but side effects occur and organ burden increases
Solution Approach 1:
The patent replaces pharmacological treatment with electrical stimulation therapy. Instead of using medications that chemically affect the bladder and nervous system, the invention applies electrical fields to directly modulate neural activity in the sacral nerve or dorsal root ganglion, thereby treating overactive bladder symptoms without drug-related side effects or organ burden
Solution Approach 2:
The patent introduces an electrical stimulation device as an intermediary between the patient and the treatment outcome. The device delivers controlled electrical signals through electrodes placed on or near the sacral nerve or dorsal root ganglion, serving as a mediator to modulate neural function and achieve symptom relief without direct drug administration
2Reliability
If conventional electrical stimulation is applied frequently to maintain symptom relief, then therapeutic effect is sustained, but patient comfort decreases and treatment inconvenience increases
Solution Approach 1:
The patent employs periodic electrical stimulation with optimized frequency and duration parameters. By delivering stimulation in controlled cycles rather than continuous application, the device maintains therapeutic effectiveness while allowing rest periods that improve patient comfort and reduce treatment burden
Solution Approach 2:
The patent utilizes high-frequency electrical stimulation (200-1000 KHz) with specific voltage ranges (−10V to −1V or 1V to 10V) and pulse durations (1-250 ms). These parameter optimizations enable effective neural modulation with fewer treatment sessions compared to conventional low-frequency stimulation, thereby improving patient convenience while maintaining symptom relief
3Reliability
If surgical interventions are performed to treat overactive bladder, then long-term symptom relief is achieved, but infection risk increases
Solution Approach 1:
The patent replaces surgical mechanical interventions with non-invasive or minimally invasive electrical stimulation. Instead of performing surgeries such as bladder augmentation, detrusor myomectomy, or pudendal neurectomy that carry infection risks, the invention uses electrical fields to modulate neural function, achieving comparable long-term symptom relief without surgical complications
Solution Approach 2:
The electrical stimulation device serves as a non-surgical intermediary to achieve therapeutic outcomes. Rather than physically altering bladder anatomy through surgery, the device uses electrical signals to modulate neural activity in the sacral nerve or dorsal root ganglion, providing long-term symptom relief without creating surgical wounds or infection risks
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 electrical stimulation method effectively reduces symptoms of overactive bladder for extended periods without the side effects of medications and minimizes the risk of infection associated with surgical interventions, allowing for less frequent treatment sessions.
Implementation Method 1
An electric field covering the target zone is generated between the first electrode and the second electrode according to the first electrical stimulation signal
