Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed electrode is used for high-frequency treatment, then the treatment can be applied to the skin, but heat accumulates in a local area causing burning
Solution Approach 1:
The patent applies the dynamics principle by replacing the fixed electrode with a rotatable roller electrode. The roller electrode rotates during treatment, continuously changing the contact point on the skin surface. This dynamic movement prevents heat accumulation at any single location, thereby eliminating burning while maintaining effective high-frequency treatment delivery.
2Adaptability or versatility
If a fixed electrode is used and continuously rubbed on the treated area, then massage effect is increased, but friction causes fatigue and pain
Solution Approach 1:
The roller electrode rotates during treatment, transforming the sliding friction of a fixed electrode into rolling friction. This dynamic rotation reduces the coefficient of friction significantly, allowing continuous massage movements without causing fatigue or pain to either the practitioner or patient, while maintaining versatile massage effects.
3Device complexity
If a fixed electrode is used, then the device structure is simple, but the treatment method is limited
Solution Approach 1:
By making the electrode rotatable, the patent adds a degree of freedom to the treatment process. The roller electrode can rotate in different directions and at different speeds, enabling various massage techniques (circular motion, linear motion, vibration) to be applied to different skin conditions, thus greatly enhancing treatment versatility without significantly increasing device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Prevents burning and discomfort during treatments, enhances treatment convenience and comfort, and maximizes therapeutic effects through selective use of roller and ball electrodes.
Implementation Method 1
When the high frequency current is applied to the tissue, whenever the current changes the direction thereof, the molecules that make up the tissue vibrate and rub against each other, generating biological thermal energy.
Implementation Method 2
the handpiece for high-frequency treatment repeatedly performs the action of continuously rubbing the treated area during the treatment in order to increase the massage effect when used. In this case, friction is generated between the skin and the fixed electrode, causing unnecessary fatigue and pain for both a practitioner and a patient.

AI summary
Disclosed is a high frequency treatment handpiece having roller electrodes. The handpiece includes: a handpiece casing part; and a plurality of roller electrode members rotatably positioned on a lower surface of the handpiece casing part and applying a high frequency by being brought into contact with the skin. The handpiece prevents burning when the continuous rubbing of a treated area is performed during a treatment, allows a practitioner to conveniently perform the treatment, and allows a person being treated to comfortably receive the treatment with minimum pain. Ball electrodes and roller electrodes can be selectively used, and a roller fixed mode, which limits the rotation of the roller electrodes, can also be selectively used, and thus various massage effects can be selectively provided in accordance with the condition of a patient's skin, and the effect of the high frequency treatment can be maximized by means of the various massage effects.
