Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing non-invasive methods for subcutaneous fat reduction and skin tightening often require direct contact with the skin, leading to bio-compatibility issues, the need for active cooling, and risk of burns, while invasive methods are painful and traumatic with undesirable side effects.
Innovation Solution
A non-contact system using capacitive electrodes to transmit electromagnetic energy into subcutaneous tissue for selective deep heating, reducing the volume of lipid-rich cells and remodeling collagen, without physical contact or continuous applicator movement, allowing passive skin cooling and simultaneous treatment of large areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If direct contact with skin is used for subcutaneous treatment, then electromagnetic energy can be transmitted effectively, but bio-compatibility issues arise and active cooling is required
Solution Approach 1:
The patent introduces air as an intermediary medium between the capacitive electrodes and the skin surface. This air gap allows electromagnetic energy to penetrate the skin effectively while preventing direct contact between the electrodes and skin, thereby eliminating bio-compatibility issues and the need for active cooling systems.
2Productivity
If invasive methods are used for fat reduction, then fat removal is effective, but pain and trauma occur with undesirable side effects
Solution Approach 1:
The patent replaces mechanical invasive methods (such as surgical liposuction) with a non-invasive electromagnetic field-based system. The capacitive electrodes generate electromagnetic energy that penetrates the skin and selectively heats subcutaneous fat tissue, causing lipolysis without mechanical trauma, pain, or surgical side effects.
3Temperature
If non-invasive heating methods are used, then fat tissue can be heated, but skin cooling is required to prevent damage
Solution Approach 1:
The air gap acts as a thermal insulator that prevents heat transfer from the electrodes to the skin surface. This allows the system to heat subcutaneous tissue effectively while the air medium naturally isolates the skin from excessive heat, eliminating the need for complex active cooling systems.
4Area of stationary object
If applicator moves continuously during treatment, then treatment area coverage is improved, but user attention and operation complexity increase
Solution Approach 1:
The patent employs capacitive electrodes with a large surface area that can be positioned statically on the skin. The electromagnetic field generated by these electrodes penetrates deeply into the subcutaneous tissue, allowing treatment of large areas without continuous movement. The system transitions from dynamic manual operation to static positioning with automated treatment.

AI summary
Methods for focused remodeling and downsizing the volume of subcutaneous lipid-rich cells, body contouring, and tightening skin tissue, using controlled heating of the targeted areas on the body. The electromagnetic energy heats the subcutaneous tissues which provides the desired effect. The electromagnetic energy is applied via an applicator without touching the skin. A spacer of insulating or dielectric material may be provided between the applicator and the skin.
