Massage Head With Segmented Movable Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional massage devices have limited uniformity in massage effect due to axial movement, requiring continuous device repositioning to achieve a uniform massage on the skin.
Innovation Solution
The design incorporates multiple movable massage elements that interact with a rotary coupling element, allowing for translational movement between different positions to create a uniform massage surface, with adjustable speed and pressure, and utilizing a turntable with elevations to guide massage members for pulsating action.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a single massage element is moved axially to exert pressure on the skin, then the device structure is simple, but the massage effect uniformity is poor and requires continuous device repositioning
Solution Approach 1:
The single massage element is divided into multiple segmentation elements (first massage element, second massage element, etc.) arranged in sequence. Each element can be independently actuated by the coupling element to deflect the massage surface at different locations, achieving uniform massage coverage without continuous device repositioning.
Solution Approach 2:
The massage elements are designed to be movable between first and second positions, with the coupling element enabling dynamic deflection of the massage surface. This dynamic capability allows the system to adapt and provide uniform massage pressure across different areas of the skin.
2Manufacturing precision
If multiple massage elements are added to improve massage uniformity, then the massage effect is enhanced, but the device complexity increases
Solution Approach 1:
Multiple massage elements and their actuation mechanisms are merged into a single integrated coupling element. This coupling element simultaneously controls the movement of multiple massage elements, reducing overall device complexity while maintaining the ability to provide uniform massage across multiple surface locations.
Solution Approach 2:
The coupling element is designed as a multi-functional component that performs multiple functions: it actuates multiple massage elements, enables temporal offset control, and provides the mechanical linkage between the drive and massage elements. This universal component reduces the need for separate mechanisms for each function.
3Manufacturing precision
If massage elements are moved with time offset to create uniform massage surface, then the massage uniformity is improved, but the control complexity increases
Solution Approach 1:
The coupling element is designed to move massage elements in a periodic sequence with temporal offsets. This periodic action ensures that different portions of the massage surface are activated in sequence, creating a uniform overall massage effect while using simple mechanical timing rather than complex electronic control.

AI summary
In a massage head (1) comprising a housing (4), a flexible massage element (3) with a massage surface, and a coupling element (5) which is connectable in terms of drive to a drive element, a plurality of massage members (7) are provided which are arranged so as to be movable in at least one direction from a first position to a second position and, in the second position, interact with the massage element (3) for local excursion of the massage surface, and the coupling element (5), in the driven state, interacts with the plurality of massage members (7) in such a way that the massage members (7) are moved from the first position to the second position in a manner staggered in time in relation to each other.
