Lifting Beauty Device With Rotating HIFU Plug for Dual-Depth Targeting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beauty devices using high-intensity focused ultrasound (HIFU) lack the ability to selectively target the SMAS (Superficial Musculo Aponeurotic System) layer or dermis layer for non-invasive wrinkle removal and skin elasticity enhancement, often requiring multiple treatments and operator fatigue due to emission depth limitations.
Innovation Solution
A lifting beauty device with a body portion generating rotational power and a cartridge portion emitting HIFU at two depths (4.5 mm and 3.0 mm) to target the SMAS or dermis layer, utilizing a mechanism with a head module and guide plate to switch emission depths, eliminating the need for replacing ultrasound emission plugs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single ultrasound emission plug is used, then the device structure is simple, but the emission depth cannot be selectively switched between SMAS layer and dermis layer
Solution Approach 1:
The patent implements a rotatable ultrasound emission plug structure that can dynamically switch between different emission depths. The plug rotates around a central axis to change the orientation of its emission surface, enabling selective targeting of either the SMAS layer (deeper penetration) or dermis layer (shallower penetration) without requiring multiple separate plugs or complex mechanical assemblies.
Solution Approach 2:
A single ultrasound emission plug is designed to perform multiple functions by rotating to different positions. The same physical component can emit ultrasound at different depths and angles, making one plug universally applicable for treating different skin layers and facial areas, thereby eliminating the need for multiple specialized plugs.
2Adaptability or versatility
If multiple ultrasound emission plugs are used to target different depths, then the emission depth can be selected, but the device complexity and operation time increase
Solution Approach 1:
The rotatable plug design allows instantaneous switching between emission depths by simply rotating the single plug to the desired position, eliminating the time-consuming process of removing and replacing multiple plugs. The operator can switch between SMAS layer treatment and dermis layer treatment within seconds by rotating the plug rather than changing components.
Solution Approach 2:
The single multi-functional plug eliminates the need for a collection of single-purpose plugs. By making one plug capable of multiple emission depths and angles, the device reduces both the physical clutter of multiple plugs and the operational time required to switch between them.
3Adaptability or versatility
If the ultrasound emission angle is fixed, then the device structure is simple, but it cannot adapt to different facial areas and treatment depths
Solution Approach 1:
The ultrasound emission plug is designed with rotational capability around a central axis, allowing the emission angle to be dynamically adjusted. This dynamic angle adjustment enables the operator to target different facial areas and tissue depths by rotating the plug to appropriate orientations, while maintaining a relatively simple overall device structure.
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 device allows selective emission to the SMAS or dermis layer, reducing treatment time and operator fatigue by enabling precise depth control, thereby regenerating collagen for wrinkle removal and skin elasticity without invasive procedures.
Implementation Method 1
high-intensity focused ultrasound is used to only act on the SMAS layer without touching the epidermis, the heat from the ultrasound is transferred to a deep portion of the dermis layer
Implementation Method 2
an ultrasonic oscillation head that emits the high intensity focused ultrasound (HIFU)

AI summary
The present invention provides a lifting beauty device using high-intensity focused ultrasound that includes a body portion having a circumference gripped by a hand of a user and configured to generate a rotational power as the user operates an operation button exposed on a surface, and a cartridge portion that is coupled to a front side of the body portion and emits high intensity focused ultrasound (HIFU) while moving along a corresponding path by the rotational power generated by the body portion and selectively switching an emission depth in two stages depending on an operation mode, that may selectively switch an emission depth of the high-intensity focused ultrasound (HIFU) such that the high-intensity focused ultrasound (HIFU) may selectively reach an SMAS (Superficial Musculo Aponeurotic System) layer, which is a fibrous fascia layer that is part of a muscle layer, or a dermis layer.
