Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the operator frequently checks whether the RF electrode is brought into close contact with the skin during the procedure, then the safety of the treatment is improved, but the treatment time increases and operator productivity decreases
Solution Approach 1:
The system performs self-monitoring through the detection unit that automatically detects whether the RF electrode is in close contact with the skin, eliminating the need for operator intervention. The control unit then automatically adjusts operating parameters based on this detection, making the safety monitoring a self-service function of the device itself.
Solution Approach 2:
The detection unit provides real-time feedback about electrode-skin contact status to the control unit, which then adjusts operating parameters accordingly. This closed-loop feedback system ensures continuous safety monitoring without requiring manual checks, thereby maintaining safety while improving productivity.
2Reliability
If the operator applies a lot of force to press the handpiece to bring the entire surface of the RF electrode into close contact with the skin, then the contact reliability is improved, but the operator experiences joint diseases and patient discomfort increases
Solution Approach 1:
The detection unit automatically monitors contact status and the control unit adjusts parameters to maintain optimal contact, eliminating the need for the operator to manually apply excessive force. The system self-regulates to achieve and maintain reliable contact through intelligent control rather than mechanical force.
Solution Approach 2:
The manual mechanical pressing action by the operator is replaced with an automated detection and control system. The detection unit senses contact status and the control unit manages the electrode positioning or parameters, substituting mechanical force application with intelligent automated control.
3Ease of operation
If the RF electrode is not brought into close contact with the skin during the procedure, then the operator convenience is improved, but the skin temperature rises rapidly causing burns
Solution Approach 1:
The detection unit continuously monitors whether the RF electrode is in close contact with the skin and provides feedback to the control unit. When contact is detected, the control unit adjusts operating parameters to prevent rapid temperature rise, thereby preventing burns while allowing operator convenience.
Solution Approach 2:
The system takes preliminary action by detecting contact status before significant temperature rise can occur. The control unit proactively adjusts parameters in response to detection unit signals, preventing the harmful effect of rapid temperature increase and skin burns before they can happen.

Implementation Method 1
a ball joint part connecting the first casing part and the second casing part, thereby allowing the first casing part to be freely tilted for all ranges of 360 angle degrees within a radius of the first casing part
Implementation Method 2
an RF electrode body positioned on one surface of the cartridge casing and being brought into contact with skin to apply RF energy inside the skin
Implementation Method 3
a bellows member having one end part side connected to the first casing part and an opposite end part side connected to the second casing part, positioned to surround the ball joint part, and provided with a plurality of corrugation parts

AI summary
Proposed is an RF electrode cartridge for skin beauty care treatment and a handpiece for skin beauty care treatment provided with the same. While being freely tilted for all ranges of 360 angle degrees around a ball joint part 140 within a radius thereof, the RF electrode body 120 moves in a state of being brought into close contact with the skin during the procedure, thereby preventing an accident that may occur while the RF electrode body 120 is spaced apart from the skin and in which damage to the skin tissue or burns to the skin may be caused. Accordingly, the present disclosure may greatly improve safety during a procedure.
