Dual Swing-Arm Massage Structure for Multi-Directional Percussion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional massage devices are limited to percussive massage in a single direction, requiring users to adjust the device's holding direction for massaging small body parts, leading to inconvenience.
Innovation Solution
A massage device with receiving spaces on opposite sides of the shell, each containing a swing arm wrapped with elastic wrappers, driven by a rotary motor to swing in multiple directions, allowing simultaneous percussive massage on multiple body parts without adjusting the device's orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional massage device with one percussion component is used, then the structure is simple, but it can only percuss and massage a body part in one direction, requiring users to adjust the holding direction for small body parts
Solution Approach 1:
The massage device divides the single percussion function into multiple independent swing arms (at least two), each capable of independent swinging motion. This segmentation allows simultaneous multi-directional percussive massage without requiring device reorientation, resolving the contradiction between versatility and structural simplicity.
Solution Approach 2:
Multiple swing arms are integrated into a single device structure with a common driving mechanism. The swing arms work together to provide combined percussive massage effects on multiple body parts simultaneously, achieving enhanced adaptability while maintaining relatively simple overall structure through functional integration.
2Ease of operation
If users adjust the holding direction of the massage device for small body parts, then the massage direction can be changed, but it leads to inconvenience in use
Solution Approach 1:
The swing arms are designed with dynamic swinging capabilities around different axes, allowing them to adapt their massage direction automatically based on the target body part. This dynamic adjustment eliminates the need for static device reorientation, significantly improving ease of operation and reducing time loss.
Solution Approach 2:
The massage device automatically adapts to different body parts through the independent swinging motions of multiple swing arms, eliminating the need for user intervention to adjust holding direction. The device serves itself by providing multi-directional massage coverage without requiring user repositioning actions.
3Object-affected harmful factors
If the wrappers are made from elastic material, then comfortable massage is provided, but the structural complexity increases
Solution Approach 1:
Elastic wrappers are applied to the swing arms to provide comfortable contact with the body during percussive massage. These flexible coverings conform to body contours and distribute impact forces, enhancing comfort while adding minimal structural complexity through the use of thin elastic material layers.

AI summary
A massage device includes a shell. Receiving spaces are formed in opposite sides of the shell, and an accommodating chamber is formed in the shell and located on one side of the receiving spaces. A driving device is arranged in the accommodating chamber. At least one massage component is connected to and driven by the driving device. The massage component includes two swing arms and wrappers wrapping free ends of the swing arms respectively located in the receiving spaces. When the driving device drives the massage component to swing, the two swing arms on the same massage component swing in a same direction or in opposite directions between inside the receiving spaces and outside the shell. The massage device can realize synchronous percussive massage of multiple body parts in different directions of users without adjusting the direction in which the massage device is held.
