Solution Overview
Problem
Current aesthetic treatments for body shaping and cellulite reduction are inefficient, often causing adverse effects such as panniculitis, non-homogeneous temperature distribution, and pain, and lack the ability to combine the effects of time-varying magnetic fields with conventional treatments.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If large currents are used in magnetic field generating devices made of metallic strips or electric wires, then the magnetic field strength is sufficient to induce muscle contraction, but significant energy losses are caused by induced eddy currents within the device
Solution Approach 1:
The magnetic field generating device is segmented into multiple insulated conductors arranged in parallel, rather than using a single thick conductor or metallic strip. This segmentation reduces the cross-sectional area of each individual conductor, thereby minimizing eddy current losses while maintaining the overall magnetic field strength through the combined effect of multiple conductors carrying current
Solution Approach 2:
An insulating material is introduced as an intermediary between adjacent conductors in the magnetic field generating device. This insulating layer prevents eddy currents from forming across conductor boundaries, reducing energy losses while allowing the device to generate sufficient magnetic field strength for muscle contraction induction
2Reliability
If thermal treatment is applied to enhance visual appearance of skin, then collagen and elastin production is increased, but risk of overheating and thermal damage to patient increases
Solution Approach 1:
The patent replaces thermal treatment mechanisms with magnetic field-based treatment. Instead of using heat to stimulate collagen and elastin production, the invention uses time-varying magnetic fields to induce muscle contractions that mechanically stimulate tissue remodeling, thereby achieving aesthetic effects without the risk of overheating or thermal damage
Solution Approach 2:
The treatment parameters are changed from thermal parameters (temperature, heating rate) to magnetic parameters (magnetic flux density, frequency, pulse duration). This parameter transformation allows the same therapeutic goals to be achieved through a different physical mechanism that does not carry the risks associated with high temperature treatment
3Reliability
If mechanical treatment is used for cellulite or adipose cell reduction, then body shaping effect is achieved, but risk of panniculitis and non-homogeneous results occurs
Solution Approach 1:
The patent merges magnetic field treatment with conventional mechanical and thermal treatment methods to create a combined therapy approach. The magnetic field component induces muscle contractions that enhance lymphatic drainage and blood circulation, while the mechanical and thermal components address adipose tissue and cellulite, thereby achieving both safety and effectiveness that neither approach could achieve alone
4Power
If magnetic field generating devices with metallic strips or hollow conductors are used, then sufficient magnetic field is generated, but unwanted heat is produced requiring cooling systems
Solution Approach 1:
The device structure is segmented into multiple thin insulated conductors rather than using thick metallic strips or hollow conductors. This segmentation reduces the cross-sectional area available for eddy current formation, minimizing heat generation while maintaining sufficient magnetic field output through the combined contribution of multiple conductors
Solution Approach 2:
The patent converts the potentially harmful effect of eddy currents (which cause unwanted heat) into a beneficial design feature by using insulated conductors that naturally suppress eddy currents. The insulation material, which might seem to add complexity, actually serves to eliminate the harmful heating effect and reduce the need for cooling systems
