Massage Head Motorized Flap Pinching Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing massage apparatuses face inefficiencies due to leaks and jamming issues with suction-based systems, leading to inadequate tangential stimulation and pinching action on the skinfold, particularly with partition walls that rely on vacuum for movement.
Innovation Solution
A massage head with motor-driven flaps that pivot using a geared motor and cam mechanism, allowing independent mechanical actuation of the skinfold formation and pinching action, enhancing the 'Jacquet pinching' technique for deeper and more efficient skin stimulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If suction-based systems with partition walls are used to create skinfold pinching, then the pinching action is achieved, but leaks and jamming occur leading to vacuum breakdown and reduced treatment efficiency
Solution Approach 1:
The patent replaces the suction-based mechanical system with a motor-driven mechanical system. The geared motor directly actuates the partition walls to pivot and pinch the skinfold, eliminating dependence on vacuum pressure. This substitution resolves the reliability issue by removing the suction circuit and its associated leaks and jamming problems.
Solution Approach 2:
The patent extracts and removes the suction circuit from the massage head design. By eliminating the vacuum generation system, the invention removes the source of leaks and pressure-related jamming, thereby improving reliability while maintaining the pinching function through direct mechanical actuation.
2Force
If partition walls are actuated by vacuum pressure, then pinching action is produced, but tangential stimulation is insufficient due to jamming and vacuum breakdown
Solution Approach 1:
The patent implements dynamic actuation of the partition walls through a geared motor that enables controlled pivoting motion. This dynamic mechanical actuation allows the partition walls to actively engage and release the skinfold, providing both pinching force and tangential stimulation through the rolling motion, thereby resolving the insufficiency of tangential stimulation.
Solution Approach 2:
The geared motor provides periodic actuation of the partition walls, creating a rhythmic pinching and releasing action. This periodic mechanical motion enhances both the pinching force and the tangential stimulation by systematically working the skinfold through repeated cycles of engagement and release.
3Ease of manufacture
If suction circuit is used to form skinfold, then skinfold formation is achieved, but complex assemblies result that are difficult to form and not fully satisfactory
Solution Approach 1:
The patent extracts and removes the suction circuit and its associated complex components from the massage head. This elimination of the vacuum system simplifies the overall assembly, making the device easier to manufacture and assemble while maintaining the core skinfold formation capability through direct mechanical means.
Solution Approach 2:
The patent replaces the complex suction-based mechanical system with a simpler motor-driven system. The geared motor and partition wall mechanism provide a more straightforward assembly that eliminates the need for suction circuits, seals, and vacuum control components, thereby improving ease of manufacture.

AI summary
A casing defining an internal chamber having a skinfold formed therein when it is applied to a patient's skin, said fold coming into contact with the lower edges of the chamber. The chamber is defined by two lateral walls and by two transverse walls, at least one of said transverse walls being formed of a flap capable of having a pivoting motion, to induce the coming closer and the drawing away from each other of the lower edges of said transverse walls in contact with the skinfold. The flap is hinged in the vicinity of its upper end on the lateral walls. The pivoting of the flap is obtained by means of a geared motor fixedly assembled within said flap, and having its output shaft rotating a cam, received in a cam race fastened to one of the lateral walls of the internal chamber.
