Solution Overview

Problem

Existing neurostimulation systems are limited by their inability to provide coordinated stimulation to multiple body regions, are cumbersome and difficult to use, and often cause discomfort due to stimulation-induced pain and muscle fatigue, requiring daily maintenance and adjustment.

Innovation Solution

A portable neurostimulation assembly that uses percutaneous or surface-mounted electrodes with a microprocessor-based electronics pod for selective stimulation, allowing wireless control and power management, and includes a disposable patch or carrier for ease of use and mobility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If surface electrodes are used for neurostimulation, then the device is easier to apply, but stimulation-induced pain and muscle fatigue increase

Engineering Contradiction:
Improveease of electrode applicationVSAvoidstimulation-induced pain
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The neurostimulator is divided into multiple independent channels, each capable of stimulating different muscle groups or nerve regions separately. This segmentation allows for more precise control of stimulation parameters for each channel, reducing unwanted spread of stimulation and minimizing pain and muscle fatigue while maintaining ease of application.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If surface electrodes are used to stimulate deep muscles, then the device is simpler to use, but unwanted stimulation of superficial muscles occurs

Engineering Contradiction:
Improvesimplicity of device useVSAvoidprecision of stimulation targeting
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

Each electrode channel is configured with specific parameters (amplitude, pulse width, frequency) optimized for its target depth and location. The system provides locally tailored stimulation characteristics for each channel, enabling deep muscle stimulation while preventing unwanted activation of superficial muscles through precise parameter control rather than requiring complex device operation.

Inventive Principle:
Principle #3Local quality

3Reliability

If existing neurostimulation systems are used, then single-region stimulation is achieved, but coordinated stimulation to multiple body regions is not possible

Engineering Contradiction:
Improvesingle-region stimulation effectivenessVSAvoidcoordinated multi-region stimulation capability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The neurostimulator incorporates multiple independent channels within a single device, each capable of stimulating different body regions. The channels can be programmed and controlled to work independently or in coordinated fashion, providing both reliable single-region stimulation and versatile multi-region coordinated therapy for comprehensive treatment options.

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Reliability

If traditional neurostimulation controllers are used, then dedicated stimulation function is provided, but the controllers are large and awkward to manipulate and transport

Engineering Contradiction:
Improvededicated stimulation functionVSAvoidcontroller size and portability
Core Design Contradiction:
ReliabilityVSWeight of moving object

Solution Approach 1:

Multiple stimulation channels and control functions are merged into a single integrated portable unit. The device combines the stimulator, power source, and control interface in one compact package, maintaining reliable dedicated stimulation functionality while significantly improving portability and ease of manipulation compared to traditional separate controller systems.

Inventive Principle:
Principle #5Merging (Combining)
