Adjustable Eccentric Massage Head for Variable Tapping Depth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing massage apparatuses, such as fascia guns, lack the ability to adjust the movement depth of the massage head, failing to accommodate the varying thickness of fascia layers across different body parts.
Innovation Solution
A massage apparatus with an adjustable massage depth is achieved through a driver, driving link, adjusting mechanism, eccentric wheel, and slider, allowing the radial dimension of the driving link's center end to be adjusted relative to the motor's rotation center, enabling flexible depth adjustments via the eccentric radius change.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional eccentric wheel structure is used, then the massage apparatus can achieve high-frequency tapping motion, but the massage depth cannot be adjusted
Solution Approach 1:
The patent makes the eccentric radius adjustable by allowing the slider to move radially along the eccentric wheel's rotation axis. This dynamic adjustment capability enables the massage depth to be changed without replacing the entire eccentric wheel structure, resolving the contradiction between adaptability and device complexity.
Solution Approach 2:
The patent changes the eccentric radius parameter by adjusting the slider's radial position on the eccentric wheel. This parameter adjustment allows the same eccentric wheel structure to produce different massage depths, achieving adaptability without increasing overall structural complexity.
2Adaptability or versatility
If the eccentric radius is increased to increase massage depth, then deeper fascia layers can be reached, but the apparatus cannot accommodate thinner fascia areas
Solution Approach 1:
The slider's radial movement capability allows users to dynamically adjust the eccentric radius according to the specific body part being massaged. This provides operational flexibility to accommodate both thick and thin fascia areas with a single apparatus.
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 apparatus can adapt to different fascia layer thicknesses by adjusting the massage depth, providing a flexible and convenient massage experience tailored to various body parts.
Implementation Method 1
an output end of the driver is coupled to an eccentric wheel to drive the eccentric wheel to rotate
Implementation Method 2
the rotation of the motor shaft, through the eccentric wheel and the driving link, causes the massage head to move forward and backward to perform high-frequency tapping on the human body

AI summary
Provided is a massage apparatus, comprising: a driver (910), a connecting rod (800), a massage member (940), an adjusting mechanism, an eccentric wheel (500), and a sliding member (600). An output end of the driver (910) is connected to the eccentric wheel (500) so as to drive the eccentric wheel (500) to rotate. The sliding member (600) is arranged on one side of the axis of the eccentric wheel (500) and can move radially relative to the axis of the eccentric wheel (500). The movement of the adjusting mechanism actuates the sliding member (600) to move radially relative to the axis of the eccentric wheel (500). The sliding member (600) is connected to a central end (810) of the connecting rod (800) so as to adjust the distance between the central end (810) of the connecting rod (800) and the axis of the eccentric wheel (500). A traction end (820) of the connecting rod (800) is connected to the massage member (940). The massage apparatus allows the connection center of the connecting rod (800) to move close to or far from the rotation center of a motor in both working and non-working states of a fascia gun by means of adjusting the radial distance between the connection center of the connecting rod (800) and the rotation center of the motor, so as to make changes in the radial size of the eccentric wheel and thus adjust the movement depth of the massage member (940).
