Multi-Layer Coil Winding for Tinnitus Magnetic Field Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for generating alternating magnetic fields for treating tinnitus lack effective methods to induce targeted eddy currents in organisms, particularly in the vegetative nervous system, and do not provide sufficient details on coil winding techniques.
Innovation Solution
A device with coils having at least two layers with different windings, specifically orthocyclic and helical windings, is used to generate adjustable low-frequency magnetic fields with steep harmonic pulses, which are synchronized with the EEG-α rhythm of the patient, and can be integrated into a headphone for precise positioning and combined with sound therapy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional single-layer coils are used, then the device structure is simple, but the ability to generate steep harmonic-containing pulses is insufficient
Solution Approach 1:
The coil is divided into multiple layers with different winding patterns (orthocyclic and helical windings). Each layer segment contributes differently to the magnetic field generation, enabling the production of steep harmonic-containing pulses that cannot be achieved with a single uniform layer.
Solution Approach 2:
Different portions of the coil (different layers) are given different winding characteristics. The orthocyclic winding in one layer and helical winding in another layer create localized variations in magnetic field distribution, which collectively produce the desired steep pulse waveform with harmonic components.
2Reliability
If regular superimposed layers are used, then coil production is simple and reproducible, but the induced eddy currents in the organism are not targeted enough
Solution Approach 1:
The coil employs asymmetric winding patterns where at least one layer has orthocyclic winding and another layer has helical winding. This asymmetric design creates specific magnetic field distributions that enable targeted eddy current induction in the organism, while still maintaining reproducible manufacturing through standardized winding patterns.
3Length of stationary object
If high frequency is used, then penetration depth is improved, but the sensitivity of the organism is reduced
Solution Approach 1:
The device uses periodic alternating magnetic fields at low frequencies (below 100 Hz, particularly 1-20 Hz) that synchronize with the organism's intrinsic impulses and EEG alpha rhythm. This periodic action at optimized low frequencies maximizes organism sensitivity while the multi-layer coil design ensures adequate penetration depth through constructive magnetic field accumulation.
