Massage Roller Spacing Adjustment for Skin Pleating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing skin massage devices are inadequate in providing a comprehensive, comfortable, and effective massage for the face, often causing unpleasant sensations due to inadequate pleating and pinching forces that do not adapt to individual skin thickness and sensitivity.
Innovation Solution
A massage device with synchronized and reversed rotation of two rollers along parallel axes, adjustable spacing, and a system to control pinching forces, featuring a transmission mechanism with toothed wheels and spring-loaded adjustment to maintain equilibrium, along with optional features like wave emission, product dispensing, and iontophoresis for enhanced skin treatment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the rollers are positioned close together to provide effective skin pleating, then the massage effectiveness is improved, but the pinching force becomes too strong and causes pain
Solution Approach 1:
The roller spacing is made adjustable rather than fixed, allowing the distance between rollers to be dynamically modified according to user needs and skin sensitivity, thereby optimizing the balance between massage effectiveness and comfort
Solution Approach 2:
The spacing parameter between rollers can be changed to different positions, enabling the device to adapt pinching force to individual skin thickness and sensitivity variations across different facial areas
2Object-affected harmful factors
If the rollers are positioned far apart to reduce pinching force, then comfort is improved, but the skin pleating effectiveness is reduced
Solution Approach 1:
The adjustable roller spacing mechanism allows dynamic optimization of the balance between comfort and effectiveness, enabling users to find the optimal spacing for each treatment area
Solution Approach 2:
By modifying the spacing parameter, the device can adapt to different skin conditions and treatment requirements, maintaining effective pleating while minimizing discomfort
3Device complexity
If fixed roller spacing is used to simplify device structure, then device complexity is reduced, but adaptability to individual skin conditions is lost
Solution Approach 1:
The adjustable spacing mechanism adds minimal complexity while providing significant adaptability benefits, allowing the device to accommodate individual skin variations
Solution Approach 2:
The adjustable spacing feature enables the device to serve multiple functions and adapt to different user needs, skin types, and treatment areas, enhancing versatility
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 provides a more complete and pleasant skin pleating experience, minimizing pain by adapting to individual skin conditions and promoting toned skin through controlled pinching forces, while allowing for additional treatments like cosmetic product application and transcutaneous iontophoresis.
Implementation Method 1
a system for adjusting the spacing of the rollers under the action of the forces exerted on these rollers during their rotation, configured to initially define a minimum spacing between the rollers then to adjust the spacing of the rollers until a balance of the forces exerted directly and/or indirectly on these rollers is reached

AI summary
The invention relates to a massage device (1) comprising a body (2) which includes motorization means (3) and a massage head (5), assembly means (59) being arranged between the body and the massage head, said head comprising an application surface (6) and two massage rollers (7, 8) arranged along two first parallel longitudinal axes (X1, X2), with a spacing between them, and partially protruding outside the application surface.According to the invention, the massage head comprises, on the one hand, a transmission mechanism configured to be driven by the motorization means and to drive in synchronous and reverse rotation the two rollers so that, in a plan view perpendicular to the two axes with the two rollers arranged at the bottom, the part (7a) of the roller (7) located on the left which protrudes from the application surface rotates in the trigonometric direction and, the part (8a) of the roller (8) located on the right which protrudes from the application surface rotates in the clockwise direction and, on the other hand, a system for adjusting the spacing of the rollers under the action of the forces exerted on these rollers during their rotation, configured to initially define a minimum spacing between the rollers and then to adjust the spacing until an equilibrium of the forces exerted on these rollers is reached.
