Solution Overview

Problem

Existing devices generating pulsed electromagnetic fields for improving body functions and microcirculation have limited long-term therapeutic effects due to their reliance on exponential functions and rapid pulse sequences, which do not significantly influence local regulatory mechanisms of microcirculation.

Innovation Solution

A device generating periodic pulses with ascending and descending envelope curves of harmonic or anharmonic oscillation profiles, controlled by measured data from non-invasive vital-microscopic and spectrometric methods, specifically targeting features of blood microcirculation such as oxygen depletion, blood cell distribution, and vasomotion, with slower pulse sequences to induce longer-lasting changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If exponential function pulses with rapid pulse sequences (5 seconds or 3 seconds pause) are used, then short-term effects on microcirculation features are achieved, but long-term therapeutic changes cannot be induced

Engineering Contradiction:

Improvepulse sequence speedVSAvoidduration of therapeutic effect

Core Design Contradiction:

SpeedVSDuration of action of stationary object

Solution Approach 1:

The patent applies periodic action by using pulse sequences with extended intervals (10-60 seconds between pulses) rather than rapid continuous pulsing. This periodic structure with longer rest periods allows cumulative physiological effects to develop, transforming short-term transient responses into long-term therapeutic changes in microcirculation regulation.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The patent changes the temporal parameters of the electromagnetic pulses by extending the interval between pulses from 3-5 seconds to 10-60 seconds. This parameter modification fundamentally alters the physiological response, enabling long-term adaptive changes in microcirculatory regulation while maintaining the therapeutic effectiveness of the electromagnetic field application.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If exponential function envelope curves are used in pulses, then specific effects on microcirculation features are achieved, but significant and long-lasting changes in local regulatory mechanisms cannot be induced

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent inverts the conventional approach by replacing exponential function envelope curves with sinusoidal oscillation profiles. This inversion of the mathematical function type fundamentally changes the pulse characteristics, enabling significant and long-lasting influence on local regulatory mechanisms of microcirculation while maintaining reliable effects on microcirculation features.

3Duration of action of stationary object

If pulse sequences of 1 pulse/20 minutes to 4 pulses/minute are used with sinusoidal profiles, then significant long-lasting changes in microcirculation are achieved, but the treatment time between pulses increases

Engineering Contradiction:

Core Design Contradiction:

Duration of action of stationary objectVSLoss of time

Solution Approach 1:

The patent implements feedback mechanisms that allow the system to monitor physiological responses and optimize treatment protocols. This feedback enables the use of extended pulse intervals (10-60 seconds) while maintaining therapeutic effectiveness, as the system can adjust based on measured physiological changes, reducing the perceived loss of time through intelligent protocol optimization.
