Solution Overview
Problem
Existing devices for reducing fat mass using electromagnetic waves are limited in effectiveness and safety, particularly in terms of depth penetration and distribution of the magnetic field.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a single coil antenna is used to emit magnetic field, then the magnetic field intensity is sufficient, but the magnetic field acts on the body for the whole period causing excessive intensity on critical organs
Solution Approach 1:
The patent divides a single antenna into two separate coils wound in opposite directions. During the first half-period, the first coil emits magnetic field while the second coil is inactive, and during the second half-period, the roles reverse. This segmentation allows the magnetic field to act on the body for only half the period, reducing excessive intensity on critical organs while maintaining sufficient intensity during active periods.
Solution Approach 2:
The patent implements periodic action by alternating the emission of magnetic fields from the two coils in opposite half-periods. The first coil emits during the first half-period and the second coil emits during the second half-period, creating a periodic pattern that reduces overall exposure intensity to critical organs while maintaining effective treatment intensity during each active half-period.
2Device complexity
If conventional rectangular dipole antennas are used, then the device structure is simple, but the magnetic field distribution and depth penetration are limited
Solution Approach 1:
The patent employs hexagonal coil geometry instead of conventional rectangular dipole antennas. The hexagonal shape with six sides provides asymmetric current distribution that generates superior magnetic field patterns, enabling better depth penetration and more uniform field distribution across the treatment area while maintaining relatively simple device construction.
