Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electrodes are horizontally arranged or fixed on one side, then the device structure is simple, but it is difficult to uniformly treat curved body parts such as the face
Solution Approach 1:
The electrode array is divided into multiple independently movable electrodes that can be separated and positioned individually. Each electrode can move freely to adapt to the curved surface contours, allowing uniform treatment across complex body parts while maintaining a relatively simple overall device structure.
Solution Approach 2:
The electrodes are designed with movable supports that allow them to dynamically adjust their positions and orientations. This dynamic capability enables the electrodes to maintain consistent contact with curved surfaces during treatment, solving the uniformity problem without requiring a complex fixed structure.
2Productivity
If multiple electrodes are used to cover larger area, then treatment efficiency is improved, but contact consistency on curved surfaces deteriorates
Solution Approach 1:
The treatment area is covered by multiple segmented electrodes rather than a single large electrode. Each segment can independently adjust to maintain optimal contact with the curved surface, preserving contact consistency while expanding the overall treatment area and efficiency.
Solution Approach 2:
Each electrode is given independent mobility and positioning capability tailored to its specific location on the curved surface. This local adaptation ensures that every electrode maintains consistent contact quality, allowing the entire array to operate efficiently across the full treatment area.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device efficiently maintains electrode contact on curved areas, allowing for effective treatment even when the handpiece moves, ensuring consistent skin contact and improved treatment outcomes.
Implementation Method 1
When RF energy is provided to a skin surface, the molecules of a skin tissue vibrate and rub each other every time the current direction of the radio frequency changes, such that deep heat is generated due to rotation, torsion, and collision of the molecules.
Implementation Method 2
a plurality of elastic members that independently and elastically supports the other sides of the pads so that the electrodes can be three-dimensionally brought in close contact with a curved surface of the skin

AI summary
A treatment device using a high frequency according to the present invention includes: a plurality of electrodes which transfers high frequency energy to the skin; a plurality of pads each of which is provided on one surface thereof with at least one of the electrodes; and a plurality of elastic members which independently and elastically support the other surfaces of the plurality of pads, respectively, so that plurality of electrodes can be three-dimensionally and closely attached to the curved surface of the skin. Accordingly, even when treating a body region having many curves, the attachment of the electrodes is efficiently maintained. In addition, although a hand piece moves in a state in which the plurality of pads are attached to skin, the plurality of pads can be maintained in the skin attached state while actively coping with the curves.
