Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current neuromodulation devices for treating conditions like overactive bladder and incontinence require invasive procedures, are painful, and have low efficacy due to inaccurate nerve targeting and reliance on subjective patient feedback, leading to prolonged treatment sessions and potential nerve damage.
Innovation Solution
A device with a control unit, electrodes, and a response detector (such as optical, infrared, or accelerometer sensors) that automatically adjusts electrical pulse parameters based on patient movement feedback, ensuring precise nerve stimulation without the need for invasive procedures or trained medical personnel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If invasive needle insertion is used for nerve stimulation, then nerve targeting accuracy is improved, but patient pain and risk of nerve damage increase
Solution Approach 1:
The patent replaces the mechanical needle insertion method with a non-invasive electrical stimulation system that uses surface electrodes and electromagnetic fields to stimulate nerves, eliminating physical penetration while maintaining therapeutic effectiveness
Solution Approach 2:
The patent introduces a response detector as an intermediary component that objectively measures patient response to stimulation, replacing the need for direct needle-nerve contact and subjective patient reporting, thereby reducing both invasiveness and measurement uncertainty
2Ease of operation
If subjective patient feedback is used to determine stimulation effectiveness, then treatment simplicity is maintained, but measurement precision of nerve stimulation effectiveness deteriorates
Solution Approach 1:
The patent implements an automated feedback system where a response detector continuously monitors patient response to electrical stimulation and provides real-time data to a controller, which adjusts stimulation parameters automatically to optimize treatment effectiveness
Solution Approach 2:
The system performs self-adjustment of stimulation parameters based on automated detection of patient response, reducing the need for continuous manual intervention while maintaining high measurement precision through objective sensing
3Device complexity
If fixed average current parameters are used for all patients, then device complexity is reduced, but adaptability to individual patient needs deteriorates
Solution Approach 1:
The patent transforms the static fixed-parameter system into a dynamic adaptive system where stimulation current parameters are automatically adjusted in real-time based on individual patient response characteristics detected by the response sensor
Solution Approach 2:
The system automatically modifies electrical stimulation parameters including current amplitude, pulse duration, and frequency based on real-time detection of patient response, enabling customization for each patient without manual intervention
4Reliability
If prolonged treatment sessions are used to compensate for low efficacy, then treatment thoroughness is improved, but loss of time for both patient and medical staff increases
Solution Approach 1:
The automated feedback system continuously monitors treatment effectiveness and provides real-time information to adjust parameters, enabling faster convergence to optimal treatment settings and reducing the number of sessions needed to achieve therapeutic goals
Solution Approach 2:
The patent replaces manual trial-and-adjustment methods with automated electronic control and sensing systems that rapidly identify effective parameters, significantly reducing the time required to achieve effective treatment
