Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional high-frequency skin cosmetic methods using needles to apply electrical energy cause skin heating and side effects like redness or burns due to heat generation at the needle site.
Innovation Solution
A non-invasive system that injects a conductive material, such as gold nanoparticles in hydrogel, into the skin, which generates heat through an alternative magnetic field induced by a high-frequency treatment device, converting electrical energy into thermal energy without needles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a needle electrode is inserted into the skin to apply high-frequency electrical energy, then skin treatment effectiveness is improved, but heat generation at the needle site causes skin burns and redness
Solution Approach 1:
The patent introduces a conductive material as an intermediary substance injected into the skin before applying high-frequency energy. This conductive material serves as a mediator that enables effective energy transmission while distributing heat generation throughout the material volume rather than concentrating it at a needle tip, thereby maintaining treatment effectiveness while preventing localized skin burns and redness
Solution Approach 2:
The patent replaces the mechanical needle insertion system with a non-invasive approach. Instead of using a physical needle electrode that mechanically penetrates the skin, the system uses an injected conductive material combined with electromagnetic field induction, eliminating the mechanical penetration step that causes localized heat concentration and skin damage
2Reliability
If high-frequency electrical energy is applied directly through a needle, then collagen and elastin regeneration is stimulated, but the needle heats up causing side effects
Solution Approach 1:
The conductive material acts as an intermediary that separates the energy source from the skin tissue. The high-frequency energy is induced in the conductive material rather than being delivered through a heated needle, allowing collagen and elastin regeneration to occur while the conductive material absorbs and distributes the thermal energy, preventing excessive needle temperature and associated side effects
Solution Approach 2:
The patent changes the physical state and distribution of the conductive medium from a solid needle to an injected material that can be dispersed throughout the treatment area. This parameter change allows the same thermal energy to be distributed over a larger volume, reducing the temperature at any single point while maintaining the overall heating effect needed for collagen and elastin regeneration
3Use of energy by moving object
If a needle is inserted into the skin for treatment, then direct electrical energy application is achieved, but skin invasion and potential damage occur
Solution Approach 1:
The patent replaces the mechanical needle penetration system with an electromagnetic induction system. Instead of mechanically inserting a needle to deliver electrical energy, the system injects a conductive material and uses electromagnetic fields to induce currents within that material, achieving direct energy application to skin targets without mechanical invasion or associated tissue damage
Solution Approach 2:
The conductive material serves as an intermediary that enables electrical energy application without direct needle contact. The material is injected into the skin and acts as a temporary conductor that allows electromagnetic energy to be delivered to the target tissue, eliminating the need for invasive needle insertion while maintaining effective energy transfer
