Inductive Magnetic Field Coil for Contactless Fat Tissue Breakdown
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for reducing fatty tissue using pulsating magnetic fields either require body contact, indirect activation, or are not targeted enough for specific body regions, limiting their effectiveness and convenience.
Innovation Solution
A device with a large-area magnetic field coil producing 0.01 T to 0.1 T magnetic fields and capable of diphase or monophase pulses, actuated by a pulse generator, allowing for contactless and targeted stimulation of nerve and muscle contractions to break down fatty tissue in defined areas like the abdomen, buttocks, or thighs, with adjustable positioning and cooling to prevent overheating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If contactless magnetic field stimulation is used, then patient comfort and ease of operation are improved, but device complexity increases due to large-area coil requirements
Solution Approach 1:
The device is divided into modular components: a replaceable stimulation coil attached to a stand, a separate pulse generator, and an integrated cooling system. This segmentation allows the complex coil structure to be independently optimized while keeping the overall device manageable and easy to operate.
Solution Approach 2:
A plastic housing serves as an intermediary between the stimulation coil and the patient's body. This housing provides mechanical support, electrical insulation, and structural stability, allowing the use of large-area coils without increasing operational complexity for the patient.
2Productivity
If high current amplitudes are used for effective fat tissue breakdown, then treatment effectiveness is improved, but Joule heating increases requiring active cooling
Solution Approach 1:
The pulse generator delivers periodic pulsed currents rather than continuous current, allowing the coil to be stimulated effectively while having intermittent periods for heat dissipation. This periodic action maintains treatment effectiveness while reducing cumulative Joule heating.
Solution Approach 2:
An active cooling system using air flow (pneumatic cooling) is integrated into the device to remove heat from the stimulation coil during operation, enabling the use of high current amplitudes without excessive temperature buildup.
3Adaptability or versatility
If different coil shapes are provided for different body regions, then adaptability to individual body shapes is improved, but device complexity and number of components increases
Solution Approach 1:
The device is designed with dynamic replaceability of coils - different coil shapes can be attached to the stand according to the treatment area needed. This dynamic configuration allows adaptability to different body regions (abdomen, buttocks, thighs) without requiring all coils to be present simultaneously, managing complexity through modular assembly.
4Area of stationary object
If large-area coils are used for broad coverage, then treatment area is improved, but positioning precision for targeted regions becomes more difficult
Solution Approach 1:
Different coil shapes are designed with specific geometries optimized for particular body regions (abdomen, buttocks, thighs). Each coil shape concentrates the magnetic field in a specific pattern that matches the target area, providing both broad coverage within that region and targeted precision for that specific body part.
