Beauty Device Roller Axis Stability via Magnetic Drive
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beauty devices with rotating rollers face issues such as axis warping, leading to discontinuation or variation in low-frequency delivery, and inadequate skin massage due to excessive or insufficient skin stimulation.
Innovation Solution
A beauty device design featuring a pair of rotating body units coupled at a predetermined angle, supported by two bearings, with a shaft part having a tapered surface and snap rings, and a spring part for elastic support, ensuring stable rotation and uniform low-frequency delivery to the skin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a ball-shaped rotating body is rotatably coupled to a handpiece with an electric stimulus generator inside, then electric stimulus can be transmitted to the rotating body for skin massage, but the axis becomes warped during rotation causing low frequency delivery to be discontinued or intensity to vary
Solution Approach 1:
The patent introduces a magnetic field as an intermediary to transmit rotational motion from the handpiece to the rotating body without direct mechanical coupling. The electric stimulus generator creates a magnetic field that interacts with a magnetic element in the rotating body, causing it to rotate without a physical axis that could warp or sag, thereby maintaining stable low frequency delivery throughout the massage process.
2Ease of operation
If the rotating body comes into contact with the skin during rolling, then skin massage can be performed, but the skin stimulation becomes either too excessive or too minimal reducing massaging effect
Solution Approach 1:
The patent employs dynamic control of the rotating body's characteristics by varying the shape, size, and rotation speed of the rotating element. The rotating body can be configured with different geometries (spherical, cylindrical, or irregular shapes) and can rotate at variable speeds, allowing the device to adapt to different skin types, massage intensities, and treatment areas, thereby optimizing skin stimulation without being too excessive or minimal.

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 design provides a stable and effective massage with consistent low-frequency intensity, improving skin care outcomes while preventing axis sagging and ensuring efficient electron transmission, thus enhancing the cosmetic effect with reduced pain and improved productivity.
Implementation Method 1
a first bearing part formed in close contact with the step, and inserted into the shaft part, a second bearing part inserted into the shaft part, being spaced apart from the first bearing part at a predetermined interval
Implementation Method 2
a shaft part provided with a step extended in diameter, the shaft part having an inclined side on which a tapered surface is formed
