Massage Mechanism With Synchronized Clamping and Kneading Force
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing massage mechanisms with shoulder-clamping functions lack sufficient strength and stability during the massage process, and are unable to sustain satisfactory massage strength over time.
Innovation Solution
A massage mechanism with a kneading shaft and connecting members that rotate at inclined angles, allowing for synchronized shoulder-clamping, kneading, and percussion actions through a single driving member, utilizing a connecting shaft and percussion shaft with specific angle configurations to enable simultaneous movement of upper and lower massage arms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If traditional motion conversion devices are used for shoulder-clamping massage, then the massage mechanism can achieve shoulder-clamping function, but the massage strength is insufficient and cannot be sustained for a long time
Solution Approach 1:
The patent combines the shoulder-clamping massage function with the kneading massage function into a single integrated mechanism. The kneading shaft simultaneously drives both the upper and lower massage arms to perform clamping and kneading actions, eliminating the need for separate motion conversion devices and enabling sustained massage strength through coordinated multi-point action.
Solution Approach 2:
The kneading shaft serves multiple functions: it drives the upper massage arm for shoulder-clamping, drives the lower massage arm for kneeading, and can independently control the pace and strength of both actions. This multi-functional design allows a single driving component to provide sustained massage strength that would be impossible with traditional single-function motion conversion devices.
2Adaptability or versatility
If separate motion conversion devices are used for shoulder-clamping and kneading functions, then each function can be achieved independently, but the overall structure becomes complex and larger
Solution Approach 1:
The patent merges the control mechanisms for shoulder-clamping and kneading functions into a single kneading shaft system. Both the upper and lower massage arms are driven by the same rotating shaft, which coordinates their movements through mechanical linkages, thereby reducing structural complexity while maintaining functional independence.
Solution Approach 2:
The kneading shaft is designed as a universal driving component that can independently control both the upper and lower massage arms. By using a single multi-functional shaft instead of separate dedicated shafts for each function, the patent reduces the overall number of components and simplifies the mechanical structure.
3Device complexity
If the massage mechanism uses traditional linked upper and lower massage fingers, then the structure is simple, but the massage strength is insufficient and cannot be sustained
Solution Approach 1:
The patent introduces dynamic mechanical linkages that allow the upper and lower massage arms to move independently while being driven by the same kneading shaft. The arms can adjust their positions and apply force dynamically during the massage cycle, enabling sustained strong massage action without requiring complex additional actuators.

AI summary
A massage mechanism includes a connecting seat, a supporting seat assembly, upper massage arms, lower massage arms, a kneading shaft and a first driving assembly. The first driving assembly is used for driving the kneading shaft to rotate, such that a connecting member and a connecting shaft are driven to perform a reciprocating motion on each supporting seat assembly, and upper massage rolling wheels and lower massage rolling wheels are close to each other or away from each other, so as to achieve a shoulder clamping action. The two upper massage arms and the upper massage rolling wheels are driven to be close to each other or away from each other, and the two lower massage arms and the lower massage rolling wheels are close to each other or away from each other, so as to achieve a kneading action.
