Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-angle handpiece is used, then the structure is simple, but operator fatigue increases and treatment of curved body sites is difficult
Solution Approach 1:
The handpiece incorporates an adjustable angle mechanism that allows the treatment head to be dynamically repositioned at different angles relative to the handle. This dynamic adjustment capability enables operators to adapt the device to various curved body contours and treatment angles, resolving the contradiction between structural simplicity and adaptability to curved surfaces.
2Productivity
If a vacuum cap is shared among multiple users, then device cost is reduced, but hygiene issues arise due to bacterial transmission
Solution Approach 1:
The vacuum cap is designed as a disposable component that can be easily attached and detached. Each cap is intended for single-use or limited-use applications, eliminating cross-contamination risks between patients while maintaining treatment efficiency. The low cost of the disposable cap makes this approach economically viable.
3Productivity
If constant negative pressure is applied, then skin adsorption is maintained, but fat tissue decomposition is insufficient without repeated stimulation
Solution Approach 1:
The vacuum device incorporates a control mechanism that periodically varies the negative pressure applied to the vacuum cap. This periodic pressure variation creates repeated cycles of skin adsorption and release, providing mechanical stimulation that enhances fat tissue decomposition while maintaining overall skin contact. The controlled pressure fluctuations achieve better treatment results without requiring overly complex additional mechanisms.
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
The handpiece effectively adjusts to curved body sites, reduces operator fatigue, and improves fat decomposition by allowing repeated vertical relaxation and contraction of skin tissue within the vacuum cap, ensuring improved hygiene and treatment stability.
Implementation Method 1
a vacuum device for providing a reference negative pressure to the vacuum cap so that a target site of skin is adsorbed toward the hollow part of the vacuum cap
Implementation Method 2
a reference negative pressure variable device for varying the reference negative pressure in a pulse form under a condition in which the hollow part of the vacuum cap maintains a negative pressure

AI summary
Provided in the present invention is a handpiece (300) for a treatment device with improved stability and hygiene function by being configured so as to freely adjust the angle of a vacuum cap depending on a treatment site and to attach/detach the vacuum cap to/from the handpiece (300). The handpiece (300) capable of attaching/detaching a vacuum cap and adjusting an angle of the vacuum cap comprises: a vacuum cap (310) having an open lower surface and a hollow part formed therein; a body part (410) configured to attach/detach the vacuum cap (310) thereto/therefrom; a vacuum device (350) for providing a reference negative pressure to the vacuum cap so that a target site of the skin can be adhered toward the hollow part of the vacuum cap; a reference negative pressure variable device (360) for varying the reference negative pressure in a pulse form under the condition in which the hollow part of the vacuum cap (310) maintains the negative pressure; RF electrodes (320, 321) configured to be exposed to the inside wall of the vacuum cap (310) so that, when the target site of the skin has been adhered toward the hollow part of the vacuum cap (310), the skin adhered toward the hollow part comes into contact with the inside of the hollow part of the vacuum cap (310); and a control unit (380) for controlling driving of the vacuum device (350), the reference negative pressure variable device (360), and the RF electrodes (320, 321). The driving of the reference negative pressure variable device (360) and the RF electrodes (320, 321) for treating the target site of the skin is controlled so as to select any one of single driving, simultaneous driving, and alternating driving. The attachment/detachment of the vacuum cap (310) to/from the body part (410) is made by simultaneous coupling or simultaneous separation of a vacuum cap connection unit (430) that consists of a vacuum tube coupler (432) configured at an end of the body part (410), power supply connectors (433, 434), and a clip (435).
