Massage Device Worm Gear Transmission for Multi-Dimensional Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional massage devices are limited in their ability to vary massage intensity and position, offering single and monotonous motions that cannot effectively cover larger areas of the body, failing to meet the diverse massage needs of different body parts.
Innovation Solution
A massage device with a transmission mechanism comprising a motor, body mechanism, and massage mechanism, utilizing a worm and double-worm wheel, pinion and double-gear, and planetary gear to enable the massage heads to perform four simultaneous motions, allowing for continuous variation in massage strength and position over a larger region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional massage heads are used with simple mechanisms, then the device structure is simple, but the massage motions are single and monotonous, unable to meet diverse massage demands
Solution Approach 1:
The massage head is designed to perform multiple functions through four simultaneous motions (rotation, axial movement, radial movement, and oscillation), allowing it to adapt to different body parts and massage requirements without requiring multiple separate devices or complex interchangeable components
Solution Approach 2:
The transmission mechanism uses nested gear structures where planetary gears are contained within a central gear assembly, and multiple transmission stages are integrated within a compact housing, reducing overall device complexity while achieving complex motion outputs
2Adaptability or versatility
If massage heads perform three kinds of motions, then the massage intensity and position can be changed to some extent, but the motions are still felt unvaried and single, and the scope is not enough
Solution Approach 1:
The massage head incorporates four dynamic motions (rotation, axial movement, radial movement, and oscillation) that can be independently controlled and combined, creating varied and adaptive massage patterns that respond to different body contours and massage requirements
Solution Approach 2:
The transmission mechanism adds a fourth dimension of motion (oscillation) to the existing three motions (rotation, axial movement, radial movement), expanding the massage scope and creating more varied motion patterns that cover larger body areas

AI summary
A massage device includes a motor, a body mechanism and a massage mechanism. The body mechanism includes a faceplate, a soleplate, a massage transmission assembly and a move transmission assembly which are disposed between the faceplate and the soleplate. The massage mechanism fixed to the body mechanism includes at least one massage head, a massage assembly and a massage-head transmission assembly. The transmission of the massage device is through the engagement of the worm, the worm wheel, the massage transmission assembly, the gears, the gear rack, the planetary gear and the central gear. Such transmission enables the massage head to make four kinds of motions at the same time to achieve a variety of massage effects, change the intensity of strength and vary the massage position continuously in a larger region.
