Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for selectively controlling human and mammalian nerves from outside the body require invasive implants or needles, lacking non-invasive solutions for precise stimulation and sensing without surgical intervention.
Innovation Solution
A wireless Topical Nerve Stimulator and Sensor (TNSS) system that uses electrode-generated electric fields, low-frequency stimulation, and high-frequency communication to remotely control nerve responses, incorporating multiple electrodes and sensors for selective nerve stimulation and feedback, enabling non-invasive control of muscle and organ functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If invasive implants or needles are used to access nerves, then precise nerve stimulation and control is achieved, but patient risk, cost, and invasiveness increase
Solution Approach 1:
The patent replaces mechanical needle penetration with electromagnetic field-based nerve stimulation. The TNSS device uses electric fields generated by electrodes to stimulate nerves through the skin without physical penetration, thereby eliminating the harmful effects of invasive procedures while maintaining precise nerve control capability
Solution Approach 2:
The patent introduces electromagnetic fields as an intermediary between the external stimulator and the target nerves. Instead of direct mechanical contact, the electric field serves as a mediator that can penetrate tissue non-invasively to deliver precise stimulation to specific nerve structures
2Measurement precision
If multiple electrodes and sensors are integrated into TNSS, then nerve selectivity and closed-loop control improve, but device complexity increases
Solution Approach 1:
The patent divides the TNSS device into multiple independent electrodes and sensors that can be selectively activated. Each electrode/sensor element can be controlled individually or in combinations, allowing precise targeting of specific nerves while keeping the overall device architecture modular and manageable
Solution Approach 2:
The patent designs the TNSS device to perform multiple functions using the same hardware components. The electrodes serve both as stimulation sources and as sensors for detecting neural responses, while the integrated sensors provide both diagnostic information and feedback for closed-loop control, reducing the need for separate dedicated components
3Ease of operation
If wireless communication and data collection features are added, then remote control and monitoring capabilities improve, but power consumption increases
Solution Approach 1:
The patent implements periodic wireless communication rather than continuous transmission. Data is collected and transmitted at intervals or triggered by specific events (such as detection of neural responses or user requests), reducing the average power consumption of the communication subsystem while maintaining effective remote control and monitoring capabilities
Solution Approach 2:
The patent enables the TNSS device to autonomously manage its power resources by prioritizing critical functions and adjusting communication frequency based on battery status and operational needs. The device can automatically enter low-power modes when remote communication is not immediately required, allowing extended operation on limited power supplies

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 TNSS system provides fine control over nerve stimulation, reduces the need for invasive devices, offers closed-loop control, and collects data for pattern analysis, improving nerve selectivity and muscle control without the risks and costs of implants, while being convenient, disposable, and power-efficient.
