Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetic procedure devices risk causing burns due to insufficient skin suction, leading to a narrow contact area between the electrode and skin, especially when used by unskilled individuals.
Innovation Solution
A method for controlling a cosmetic procedure device that includes detecting the height of suctioned skin and determining whether to apply high frequency based on the detected height, ensuring a sufficient contact area between the electrode and skin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high frequency energy is applied when skin suction is insufficient, then the cosmetic procedure can be performed, but the contact area between electrode and skin becomes narrow causing burn risk
Solution Approach 1:
The patent measures the skin suction height before applying high frequency energy. By performing this preliminary measurement, the system determines whether the skin is sufficiently suctioned into the header part, and only allows high frequency application when the contact area is adequate, thereby preventing burns before they can occur
Solution Approach 2:
The patent implements a feedback mechanism where the measured skin suction height is used to control the high frequency application. The system continuously monitors whether the skin contact area meets safety thresholds and adjusts or prevents high frequency energy delivery based on this feedback, ensuring safe operation throughout the procedure
2Reliability
If skin suction pressure is increased to ensure adequate contact area, then burn risk is reduced, but the complexity of controlling suction pressure increases
Solution Approach 1:
The patent replaces complex mechanical pressure control systems with a simpler measurement and control approach. Instead of relying on precise mechanical regulation of suction pressure, the system uses height measurement of the suctioned skin to determine adequacy of contact area, substituting mechanical complexity with a measurement-based control strategy
