Cosmetic Roller Device with Elastic Suspension and Pump
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic massage devices fail to effectively apply a mechanical 'palpate-roll' effect and cosmetic products simultaneously, are difficult to use self-administered, especially on hard-to-reach areas, and are not ergonomic for shower use due to poor design and limited surface coverage.
Innovation Solution
A device with an elliptical base, flexible skirt, and intersecting rollers for pinching and stretching, combined with a semi-ellipsoidal grip and product dispensing system that allows simultaneous application of pressure and product, featuring a mechanical pump and sensors for optimal control and feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If rollers are placed on the contact face for mechanical massage action, then the mechanical 'palpate-roll' effect is achieved, but the cosmetic product cannot be applied simultaneously and must be applied beforehand
Solution Approach 1:
The patent combines the mechanical massage rollers and cosmetic product dispensing system into a single integrated device. The rollers and dispensing orifices are positioned to work simultaneously on the same skin area, allowing the mechanical 'palpate-roll' effect and cosmetic product application to occur at the same time, eliminating the need for separate application steps and improving overall treatment efficiency
2Reliability
If the device is designed for professional use with precise control, then the massage effectiveness is improved, but the device becomes difficult for self-administration especially on hard-to-reach areas
Solution Approach 1:
The device is designed with a compact structure that can be easily held and maneuvered by a single hand. The rollers are positioned on the contact face to provide effective mechanical action while the overall device size and shape allow users to easily reach hard-to-access areas such as the back, maintaining both effectiveness and ease of self-administration
3Stress or pressure
If the device acts on a reduced instantaneous surface due to design constraints, then the mechanical action is concentrated, but the overall treatment coverage and productivity are limited
Solution Approach 1:
The device is designed with an elliptical contact face that provides a larger treatment surface area compared to conventional rollers. This allows the device to treat larger skin areas more quickly while maintaining effective mechanical action, thereby increasing overall treatment coverage and productivity without sacrificing the concentration of mechanical action needed for effectiveness
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
Enables effective self-administered 'palpate-roll' massage on larger skin areas with precise product application, maintaining pressure and preventing rinsing, while providing ergonomic handling and feedback for optimal cosmetic treatment.
Implementation Method 1
means for elastic suspension of said toothed rollers with respect to the structure
Implementation Method 2
a pump for expelling the product contained in the reservoir through the dispensing orifice

AI summary
The invention relates to a device for applying a cosmetic product, characterized in that it comprises: a) a structure comprises a contact face and a handling face (200); b) on the contact face of the structure, a pair of notched rollers (101, 102) that are free to rotate about concurrent axes; c) elastic suspension means for said notched rollers with respect to the structure; d) on the handling face (200) of the structure, on the opposite side from the contact face, a gripping form in the form of a spherical cap enveloping the surface of the structure.
