Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current non-invasive skin treatments for reducing excess adipose tissue and improving skin elasticity are inadequate, particularly in addressing visceral white adipose tissue and subcutaneous fat, and often involve high energy levels or adverse effects.
Innovation Solution
A combination of mechanical stimulation using shock waves and electromagnetic field therapy, generated by electrohydraulic, piezoelectric, or electromagnetic techniques, applied simultaneously or sequentially to reduce fat cell volume and improve connective tissue elasticity, with energy flux densities above 1 mW·mm−2, at temperatures between 32-48°C, to remodel soft tissues non-invasively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high energy levels are used in non-invasive skin treatments, then fat cell destruction is more effective, but adverse effects and tissue damage increase
Solution Approach 1:
The patent applies periodic pulsed electromagnetic fields with specific duty cycles (e.g., 10% duty cycle with 10ms pulses at 100Hz) to deliver energy in controlled intervals. This periodic action allows tissue to recover between pulses, reducing cumulative thermal damage while maintaining effective fat cell destruction through repeated sub-lethal stress cycles.
Solution Approach 2:
The patent utilizes parameter changes by varying electromagnetic field frequency (1Hz-100Hz), pulse duration (1ms-100ms), and duty cycle (10%-50%) to optimize treatment effectiveness. By dynamically adjusting these parameters, the system achieves sufficient energy delivery for fat cell destruction while staying below thresholds that cause adverse tissue effects.
2Productivity
If mechanical stimulation intensity is increased, then tissue remodeling is more effective, but patient discomfort and potential tissue injury increase
Solution Approach 1:
The patent employs dynamic mechanical stimulation where shock wave amplitude, frequency, and duration are adjusted in real-time based on tissue response. The system transitions from high-intensity focal shock waves for initial fat cell disruption to lower-intensity radial shock waves for sustained tissue remodeling, optimizing effectiveness while minimizing discomfort.
Solution Approach 2:
The patent applies local quality by using focused shock waves that concentrate mechanical energy precisely at the fat cell layer while sparing surrounding tissues. The focal zone is positioned at specific depths (10mm-30mm) to target adipose tissue selectively, delivering high local intensity for remodeling without causing widespread tissue injury or excessive patient discomfort.
3Productivity
If treatment energy is increased to address visceral fat, then treatment effectiveness improves, but safety risks and adverse effects increase
Solution Approach 1:
The patent uses coupling media (gel or water) as intermediaries to transmit electromagnetic and mechanical energy uniformly through the tissue. This intermediary layer ensures consistent energy distribution to visceral fat deposits while preventing direct contact between the applicator and skin, reducing the risk of localized overheating or mechanical injury.
Solution Approach 2:
For visceral fat treatment, the patent employs extended periodic protocols with lower intensity pulses delivered over longer durations (e.g., 20 minutes at 50Hz with 20% duty cycle). This prolonged periodic action accumulates therapeutic effect on deep visceral deposits while allowing thermal dissipation and tissue recovery, maintaining safety even at higher total energy doses.

AI summary
Devices and methods for tissue treatment produce a mechanical stimulation therapy and electromagnetic field therapy. The mechanical stimulation therapy provides stimulation of blood circulation and stimulates treated cells. The electromagnetic field enables thermal treatment of tissue. Combination of both therapies improves soft tissue treatment, mainly connective tissue in the skin area and fat reduction.
