Finger Swinging Massage Device with Eccentric Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable massage devices offer limited massage experiences due to their single massage mode, which restricts user comfort and relaxation.
Innovation Solution
A finger swinging massage device is designed with a hard inner housing, a soft outer silica gel housing, and a swinging mechanism that converts rotary motor rotation into to-and-fro movement of a swinging rod, mimicking human fingers for improved massage comfort, featuring an eccentric wheel, limiting sleeve, and a vibrating motor for enhanced stimulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional portable massage device uses a simple structure, then it is compact and easy to operate, but the massage mode is single and massage experience is limited
Solution Approach 1:
The patent applies the dynamics principle by implementing a swinging rod mechanism that converts rotary motion from a motor into reciprocating to-and-fro movement. This dynamic conversion enables the massage head to perform swinging motions in addition to rotation, creating multiple massage modes (kneading, rubbing, tapping) from a single motor-driven system, thereby enhancing versatility while maintaining compact structure
Solution Approach 2:
The patent segments the massage device into distinct functional components: a rotating motor module, a swinging rod mechanism, and a massage head with finger-shaped protrusions. This segmentation allows each component to perform its specific function (rotation, conversion to reciprocating motion, and contact massage), enabling complex massage patterns through coordinated action of simplified individual parts
2Volume of moving object
If a conventional portable massage device uses a simple structure, then it is compact, but the massage experience is limited
Solution Approach 1:
By incorporating a swinging rod that converts rotary motion into reciprocating motion, the device achieves multiple massage modes within a compact form. The dynamic conversion mechanism allows the massage head to perform both rotational kneading and reciprocating rubbing/tapping motions, significantly enhancing massage experience without increasing device volume
Solution Approach 2:
The patent merges the functions of rotation and reciprocating motion into a single integrated mechanism driven by one motor. The swinging rod acts as a motion converter that combines rotational input with reciprocating output, allowing the device to deliver complex multi-mode massage experiences while maintaining a compact, portable design
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 device provides stable and reliable operation, enhancing massage comfort by allowing the massage portion to swing left and right, offering a more immersive experience through its ergonomic design and dual stimulation capabilities.
Implementation Method 1
an eccentric wheel connected with the rotary motor in transmission... the eccentric wheel cooperates with the limiting sleeve to convert rotation of the rotary motor into to-and-fro movement of the swinging rod
Implementation Method 2
the massage device further includes a vibrating motor received in the swinging rod

AI summary
A finger swinging massage device includes a hard inner housing, a soft outer housing surrounding the hard inner housing, and at least one swinging member installed between the hard inner housing and the soft outer housing. The at least one swinging member includes a rotary motor, an eccentric wheel connected with the rotary motor in transmission, a limiting sleeve fixed on the hard inner housing, and a swinging rod, with two opposite sides of the swinging rod rotatably connecting with the limiting sleeve, and a lower end of the swinging rod connecting with the eccentric wheel in transmission. The eccentric wheel cooperates with the limiting sleeve to convert rotation of the rotary motor into to-and-fro movement of the swinging rod, the swinging rod is exposed on a top portion of the hard inner housing, and the soft outer housing includes a massage portion corresponding to connect with the swinging rod.
