Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate tips are provided for mono-polar and bi-polar irradiation methods, then treatment effectiveness for different skin layers is improved, but device complexity and treatment cost increase
Solution Approach 1:
The patent applies multi-functionality by designing a single tip that can perform both mono-polar and bi-polar irradiation methods. The tip includes a first electrode unit and a second electrode unit with different sizes and configurations, allowing it to function as both a mono-polar electrode (when one electrode is activated) and a bi-polar electrode (when both electrodes are activated simultaneously), thereby eliminating the need for separate tips for each irradiation method
Solution Approach 2:
The patent applies segmentation by dividing the electrode structure into distinct first and second electrode units with different sizes and configurations. The first electrode unit is designed for mono-polar irradiation while the second electrode unit is designed for bi-polar irradiation. This segmented structure allows the single tip to selectively activate different electrode units or combinations thereof, enabling both irradiation methods with one tip
2Device complexity
If a single tip is used for both mono-polar and bi-polar irradiation methods, then device complexity is reduced, but RF energy transmission depth and effectiveness decrease
Solution Approach 1:
The patent applies local quality by designing the first and second electrode units with different local characteristics - different sizes, shapes, and configurations optimized for their respective irradiation methods. The first electrode unit has characteristics optimized for mono-polar irradiation to achieve deep transmission, while the second electrode unit has characteristics optimized for bi-polar irradiation. This local optimization ensures that each electrode unit maintains the transmission depth and effectiveness required for its specific function
Solution Approach 2:
The patent applies parameter changes by varying the physical parameters of the electrode units - specifically their sizes, shapes, and configurations. The first electrode unit has different dimensional parameters compared to the second electrode unit, allowing each to optimize RF energy transmission for its designated irradiation method. This parameter differentiation enables the single tip to achieve the transmission depth required for both mono-polar and bi-polar methods
3Adaptability or versatility
If mono-polar irradiation is performed with a bi-polar electrode configuration, then device versatility is improved, but RF energy transmission depth is insufficient
Solution Approach 1:
The patent applies dynamics by making the electrode activation dynamic and configurable. The system can dynamically switch between activating only the first electrode unit for mono-polar irradiation, activating only the second electrode unit for bi-polar irradiation, or activating both units simultaneously. This dynamic activation capability allows the device to adapt to different irradiation requirements while maintaining the transmission depth necessary for each method through proper electrode selection

Implementation Method 1
When high frequency energy is provided to a skin surface, molecules constituting skin tissue vibrate and rub each other every time a current direction of high frequency changes, so that deep heat is generated due to rotation, torsion, and collision of the molecules.
Implementation Method 2
