Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional RF needle equipment is used without vacuum suction, then the device structure is simple, but the needles cannot be precisely inserted into the inner skin layer due to skin curvature
Solution Approach 1:
The vacuum suction is applied before needle insertion to pre-position the skin surface against the treatment head, ensuring all needles are at the correct insertion depth before the procedure begins. This preliminary action eliminates the need for complex real-time depth adjustment mechanisms during the procedure.
Solution Approach 2:
A vacuum suction system using pneumatic principles is integrated into the device to create negative pressure that pulls the skin surface against the treatment head, ensuring precise and uniform needle insertion depth across all needles without requiring complex mechanical positioning systems.
2Adaptability or versatility
If multiple needles are used to treat curved skin surfaces, then treatment coverage is improved, but inconsistent insertion depth occurs across different needles
Solution Approach 1:
The skin is pulled against the treatment head using vacuum suction before needle insertion, pre-positioning the skin surface to ensure uniform contact across the entire treatment area. This allows all needles to insert at consistent depths simultaneously, maintaining precision while treating curved surfaces.
Solution Approach 2:
The treatment head is designed with a curved surface that matches the contour of the skin, allowing multiple needles arranged in a curved pattern to all contact the skin at appropriate angles and depths when vacuum suction is applied, thereby maintaining insertion consistency across the curved treatment area.
3Ease of operation
If needles are inserted without vacuum suction on curved skin, then the operation is simple, but treatment effectiveness is reduced due to shallow or inconsistent insertion
Solution Approach 1:
The vacuum suction is activated before needle insertion to pre-position the skin, ensuring reliable and consistent needle depth without requiring the operator to manually adjust or reposition needles during the procedure. This maintains operational simplicity while significantly improving treatment reliability.
Solution Approach 2:
The vacuum suction system automatically ensures consistent skin contact and needle insertion depth through pneumatic pressure, eliminating the need for complex manual adjustment mechanisms and maintaining ease of operation while improving treatment effectiveness and reliability.

AI summary
A skin care device using an RF needle is disclosed. According to an embodiment, a skin contact part having a plurality of needles and a vacuum pressure formation unit for applying a suction force to the skin contact part are included, and thus a needle can be inserted into the skin by pulling the skin with vacuum pressure. Therefore, the skin is pulled with suction so that an equipment contact surface accurately comes into contact with the skin, and thus a needle can be correctly inserted into the inner layer of the skin.
