Solution Overview
Problem
Existing magnetic field generating-apparatuses face challenges in applying high magnetic fields to deep tissue locations within the body, such as the brain or muscle tissue, while minimizing joule heat generation and maintaining stable operation.
Innovation Solution
A magnetic field generating-apparatus featuring a C-shaped annular core with a gap-portion and coils wound around the core's opposite-side portions, which enhances magnetic flux distribution and density at deeper tissue locations by superimposing magnetic fluxes generated by facing extended-portions, allowing for effective biostimulation with reduced power supply to minimize heat generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If high magnetic field is applied to deep tissue locations, then biostimulation efficacy is improved, but coil heat generation increases
Solution Approach 1:
The magnetic field generating apparatus is segmented into multiple independent coil units (first coil unit and second coil unit) positioned at different locations. Each coil generates magnetic flux that contributes to the total magnetic field at the deep tissue target, distributing the heat generation across multiple coils rather than concentrating it in a single high-power coil.
Solution Approach 2:
The invention transitions from a single-point magnetic field source to a distributed multi-point source configuration. By positioning coils at different spatial locations (first coil at first position, second coil at second position) and utilizing the superposition of magnetic fluxes from multiple directions, the apparatus achieves high magnetic field strength at deep tissue while distributing thermal load across multiple coil locations.
2Length of stationary object
If magnetic field is applied to deep tissue locations 10 mm or more away, then treatment coverage is improved, but magnetic field strength decreases
Solution Approach 1:
The invention merges the magnetic flux contributions from multiple coil units positioned at different locations. The first coil unit and second coil unit each generate magnetic flux that extends to the deep tissue target, and their combined effect produces sufficient magnetic field strength at distances of 10 mm or more from the apparatus, overcoming the natural decay of magnetic field with distance.
