Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for treating local impairments such as inflammation and pain, particularly in muscles, nerves, and bones, often result in unwanted side effects and are not effective for chronic conditions, as they rely on exogenous substances or complex circuitry with uncontrollable stimulation doses.
Innovation Solution
A direct current output device with a multiplicity of needles as the first electrode and a flat electrode as the second, featuring means to maintain constant current intensity through each needle, ensuring a consistent and controlled electric field similar to endogenous physiological fields, reducing side effects and improving treatment efficacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If exogenous substances (cortisone, NSAIDs, analgesics) are used for treating inflammation and pain, then therapeutic effect is achieved, but unwanted local and systemic side effects occur including adverse effects on metabolism and hormone balance
Solution Approach 1:
The patent replaces chemical substance administration with a physical stimulation method (electrical stimulation through needles). Instead of using exogenous chemical agents like cortisone or NSAIDs, the invention employs controlled electrical current delivery through acupuncture needles to stimulate the body's intrinsic healing capacities, thereby achieving therapeutic effects without the harmful side effects of pharmaceutical agents
Solution Approach 2:
The patent leverages the body's own intrinsic healing mechanisms rather than introducing external substances. By applying controlled electrical stimulation through needles, the treatment activates and enhances the body's natural anti-inflammatory and pain-relief systems, allowing the organism to treat itself without relying on exogenous chemicals that cause metabolic and hormonal disruptions
2Duration of action of moving object
If conventional therapeutic methods are used, then acute conditions can be treated, but chronic forms of disease cannot be effectively treated
Solution Approach 1:
The patent employs continuous or repeated applications of controlled electrical stimulation to maintain therapeutic effects over extended periods. The device can deliver sustained low-level current through the needles, and treatment protocols can be repeated over time, enabling effective management of chronic conditions that require long-term intervention rather than single acute treatments
3Object-affected harmful factors
If acupuncture is used for treatment, then non-pharmacological therapy is provided with fewer side effects, but the stimulation dose is uncontrollable and complex circuitry is required
Solution Approach 1:
The patent transforms traditional acupuncture by introducing controlled electrical parameters (current intensity, voltage, frequency, pulse duration) that can be precisely adjusted and regulated. The device allows systematic variation of these electrical parameters to optimize treatment effects while maintaining safety, replacing the unpredictable mechanical stimulation of traditional acupuncture with controllable electrical fields
Solution Approach 2:
The patent incorporates feedback mechanisms through current intensity sensors and control circuits that continuously monitor the electrical parameters during treatment. This feedback system automatically adjusts the stimulation to maintain optimal therapeutic levels and prevent excessive dosing, providing controllable and reproducible treatment without requiring complex manual adjustment of circuitry
4Power
If high current intensities are used in galvanotherapy, then tissue destruction can be achieved, but this is not suitable for therapeutic treatment of inflammation and pain
Solution Approach 1:
The patent applies the principle of partial action by using low-level electrical stimulation that is sufficient to activate therapeutic mechanisms but below the threshold that would cause tissue damage. The device delivers controlled micro-currents through the needles that stimulate cellular activity and promote healing without exceeding the safety threshold that would lead to necrosis or tissue destruction associated with high-intensity galvanotherapy
