Segmented Electrical Stimulation Patch with Real-Time Current Monitoring

Solution Overview

Problem

Conventional electrical stimulation devices for brain stimulation lack the ability to monitor and control voltage or current levels, risking burns to the user if higher-than-set levels are applied, as they fail to account for variations in electrical stimulation.

Innovation Solution

The device divides a patch layer into multiple segments, incorporating a monitoring unit to measure and control voltage or current across each segment, preventing excessive stimulation by blocking or adjusting current as needed to ensure safe operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional electrical stimulation device applies voltage or current for brain stimulation, then cognitive abilities may be improved, but burns may occur on user skin due to unexpected high voltage or current

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patch layer is divided into multiple segments, each with its own monitoring capability. This segmentation allows independent monitoring of voltage or current in different regions, enabling precise control and prevention of localized overheating that could cause burns.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A monitoring unit is implemented to continuously monitor voltage or current supplied to each patch segment. When abnormal high voltage or current is detected, the system provides feedback to adjust or stop stimulation, preventing burns while maintaining effective brain stimulation.

Inventive Principle:
Principle #23Feedback

2Power

If voltage or current is increased for effective brain stimulation, then cognitive improvement may be achieved, but the risk of burns increases due to lack of monitoring

Engineering Contradiction:
Core Design Contradiction:
PowerVSObject-affected harmful factors

Solution Approach 1:

The monitoring unit continuously measures voltage or current levels and provides real-time feedback. When power exceeds safe thresholds, the system automatically adjusts or terminates stimulation, allowing high power delivery when safe while preventing burns through continuous oversight.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system establishes safe operating parameters and monitoring mechanisms before delivering electrical stimulation. By pre-configuring safety thresholds and monitoring capabilities, the device can deliver effective high-power stimulation while preventing burns through proactive safety measures.

Inventive Principle:
Principle #10Preliminary action

3Device complexity

If a single patch layer is used for electrical stimulation, then device simplicity is maintained, but precise control of stimulation regions is limited

Engineering Contradiction:
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The single patch layer is segmented into multiple controllable regions. Each segment can be independently monitored and controlled, enabling precise spatial control of stimulation while maintaining the simplicity of a single-layer structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the patch layer can be selectively activated or monitored based on local requirements. This allows customized stimulation patterns across different areas of the patch while maintaining overall structural simplicity.

Inventive Principle:
Principle #3Local quality
