Massage Core Mechanism for Compact 3D Shoulder-Neck Kneading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shoulder and neck massagers have large volumes, high production costs, and limited 2D massage capabilities, resulting in poor massage effectiveness and reduced consumer experience.
Innovation Solution
A massage machine core with a compact design incorporating a brushless motor, gear transmission group, eccentric wheels, and rocker arms that enable 3D massage by allowing the massage head to move in an 'S'-shaped track, combining shoulder and neck clamping functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate driving mechanisms are used for finger massage assembly and kneading massage assembly, then massage functions are improved, but device complexity and volume increase
Solution Approach 1:
The patent combines the finger massage assembly and kneading massage assembly into a single integrated structure where one driving mechanism powers both assemblies through a shared transmission system. The first and second driving mechanisms are merged into a unified drive unit that sequentially actuates both massage functions, reducing the number of independent motors and control systems while maintaining full massage functionality.
Solution Approach 2:
The integrated driving mechanism is designed to perform multiple functions by sequentially driving both the finger massage assembly and kneading massage assembly. A single motor unit with a multi-position transmission system can switch between different massage modes, making the drive system universal rather than requiring separate dedicated motors for each function.
2Device complexity
If traditional 2D massage movement is used, then device simplicity is maintained, but massage effect quality deteriorates
Solution Approach 1:
The patent transitions from traditional 2D linear or circular massage movements to 3D multi-directional movement by adding vertical oscillation to the horizontal and rotational motions. The massage head can now move not only left-right and rotate but also oscillate up-down, creating a three-dimensional massage trajectory that better replicates human hand massage techniques and provides superior muscle relaxation效果.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution achieves a more effective 3D massage experience with reduced size and cost, enhancing market competitiveness.
Implementation Method 1
a brushless motor, the gear transmission group is connected with an output shaft of the brushless motor
Implementation Method 2
the two eccentric wheels are eccentrically fixed on both sides of the long rotating shaft corresponding to the gear transmission group, one end of the eccentric wheel toward the eccentric connecting rod forms an eccentric slope
