Solution Overview

Problem

Conventional methods for treating local impairments such as inflammation and pain in the human or animal body, including pharmaceuticals, often result in undesirable side effects and are not effective in preventing chronic conditions, while existing electrical therapies like TENS and electroacupuncture have uncontrollable stimulation doses and are not directed at local effects.

Innovation Solution

A direct current application device with a constant current source and electrodes, either needle-shaped or flat, configured to maintain a consistent current flow, reducing side effects and improving treatment efficacy by mimicking endogenous electric fields for local tissue impact.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional pharmaceutical methods are used to treat local impairments, then treatment effectiveness is achieved, but undesirable side effects and systemic impacts occur

Engineering Contradiction:
Improvetreatment effectivenessVSAvoidside effects
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces pharmaceutical chemical treatment with a physical electrical field-based treatment system. The DC application device uses electrical current to create local effects at the application site without requiring exogenous active ingredients, thereby achieving therapeutic effectiveness while avoiding systemic side effects associated with pharmaceuticals

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The device is designed to produce highly localized effects through controlled DC application at specific body regions. The electrical current is directed to create local electrochemical reactions and tissue effects precisely where needed, avoiding widespread systemic distribution of active ingredients and their associated side effects

Inventive Principle:
Principle #3Local quality

2Ease of operation

If existing electrical therapies like TENS and electroacupuncture are used, then pain relief is provided, but stimulation dose control is unprecise and local effects are not targeted

Engineering Contradiction:
Improvepain reliefVSAvoidstimulation dose control
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The DC application device incorporates current control circuitry that monitors and regulates the electrical current being applied. This feedback mechanism ensures precise control of stimulation dose, maintaining constant current levels despite variations in tissue impedance, thereby achieving reproducible and controllable treatment parameters

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The device enables precise control and adjustment of electrical current parameters including current magnitude, duration, and application timing. By controlling these parameters, the system achieves accurate stimulation dose delivery and targeted local effects, overcoming the imprecision of conventional electrical therapies

Inventive Principle:
Principle #35Parameter changes

3Reliability

If strong and time-varying electric fields are applied, then therapeutic effects are achieved, but electrolytic effects on electrodes and tissue occur

Engineering Contradiction:
Improvetherapeutic effectVSAvoidelectrolytic effects
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The device applies direct current in controlled periodic or intermittent patterns rather than continuous strong fields. This periodic application allows tissue and electrodes to recover between pulses, minimizing cumulative electrolytic effects and tissue damage while maintaining therapeutic effectiveness through repeated controlled stimulation

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system uses controlled DC with regulated current parameters and duration to achieve therapeutic effects without exceeding safe thresholds. By precisely controlling current magnitude and application time, the device produces beneficial electrochemical reactions while avoiding harmful electrolytic decomposition and tissue damage

Inventive Principle:
Principle #35Parameter changes
