Alternating Massage Fingers for Facial Tapping Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing skin massage devices are inadequate for providing a tapping massage on smaller, sensitive, and curved areas of the face, such as under the eyes, as they cannot replicate the frequency and duration of a professional esthetician's massage without causing discomfort.
Innovation Solution
A massage device with alternately mobile massage fingers actuated by an electric motor, featuring a gearbox and support surface that allows precise positioning and consistent force application, capable of frequencies greater than 2.5 Hz, and designed to mimic the tapping motion of two fingers, with optional features like electrophoresis, light therapy, and cosmetic product application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual tapping massage is performed by a professional esthetician, then high frequency and long duration can be achieved, but it becomes difficult or impossible to maintain without causing discomfort to the user
Solution Approach 1:
The patent replaces manual mechanical tapping with an automated motor-driven system. The motor (6) actuates massage fingers (21) through drive means (7), substituting human manual operation with mechanical automation that can maintain high frequency and duration without user fatigue or discomfort.
Solution Approach 2:
The device performs self-service by automatically executing the tapping massage sequence without requiring continuous manual intervention. The motor-driven system maintains consistent tapping frequency and duration, eliminating the need for the user to physically perform the massage and causing no discomfort.
2Ease of operation
If existing massage devices are used, then rolling or tapping massage can be performed, but they cannot replicate the precise motions of a professional esthetician on smaller, sensitive, curved areas of the face
Solution Approach 1:
The patent divides the massage function into multiple independent massage fingers (21), each capable of precise, independent movement. This segmentation allows each finger to independently tap on specific curved areas of the face, replicating the precision of manual esthetician work while adapting to the contours of the face.
Solution Approach 2:
The massage fingers (21) are designed with dynamic movement capabilities, moving between extension and retraction positions through actuation means (25). This dynamic positioning system allows the fingers to adapt to the curved surfaces of the face, providing precise tapping motion on smaller, sensitive areas while maintaining ease of operation.
3Reliability
If high frequency tapping is applied to stimulate blood circulation and treat wrinkles, then therapeutic effects are improved, but unpleasant sensations may occur on sensitive skin
Solution Approach 1:
The patent employs parameter changes by controlling the frequency, amplitude, and duration of tapping motions through the motor (6) and drive means (7). The system can adjust these parameters to achieve therapeutic frequencies for blood circulation and wrinkle treatment while maintaining intensity levels that avoid unpleasant sensations on sensitive skin.
Solution Approach 2:
The device implements periodic action through the rhythmic, alternating movement of massage fingers (21) between extension and retraction positions. This periodic tapping motion stimulates blood circulation and treats wrinkles through consistent rhythmic stimulation while the controlled periodicity prevents overwhelming or unpleasant sensations on sensitive areas.

AI summary
Provided is a facial massage device including: a massage head (1) that includes: a bearing element (20) that is intended to be placed against the face and that defines a bearing surface (S), at least one massage finger (21), each including a working head (22) intended to come into contact with the face and each being mobile between: a retracted position (R) in which the working head (22) is located short of the bearing surface (S) towards the inside of the massage head (1), an extended position (E) in which the working head (22) is located beyond the bearing surface (S) towards the outside of the massage head (1), means (25) for manoeuvring each massage finger (21) designed to move each of the massage fingers (21) alternately between the extended position (E) and the retracted position (R) thereof, and a drive housing (2) that carries the massage head (1) and that includes an electric motor (6) that actuates drive means (7) designed to transmit the drive from the electric motor (6) to the manoeuvring means (25), wherein the drive housing (2) is located opposite the working heads, relative to the bearing element (20).
