Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing massagers are unable to perform effective local (small area) vibrating massage, limiting their massaging effect.
Innovation Solution
A massaging mechanism with a driving member, eccentric shaft, guiding member, and pushing member that allows for targeted, local massage by extending and retracting along a guide hole, combined with a connecting rod and bearings to enhance stability and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a motor drives an eccentric structure to rotate and generate vibration for large area massage, then the massager can cover a large area of the body, but it cannot perform effective local (small area) vibrating massage
Solution Approach 1:
The massager is divided into multiple independent massage heads, each capable of independent vibration. This segmentation allows different parts of the massager to perform different functions - some heads for large area vibration and others for localized precise massage, resolving the contradiction between coverage area and local precision.
Solution Approach 2:
Different massage heads are designed with different structures and vibration characteristics tailored to specific needs. Some heads have larger contact areas for broad massage, while others have smaller, more focused contact points for localized precision massage, enabling each part to have optimized local quality for its specific function.
2Ease of operation
If a pushing member is slidably received in a guide hole to enable linear motion, then the structure achieves simple guidance, but frictional loss increases
Solution Approach 1:
The patent replaces the traditional sliding friction mechanism with a rolling bearing system. The rolling bearing converts sliding friction into rolling friction, dramatically reducing frictional loss while maintaining the simple linear guidance function of the guide hole structure.

Function Achieved in This Case
Enables targeted local massage with enhanced effectiveness and reduced frictional loss, improving the overall massaging experience.
Implementation Method 1
an eccentric shaft, connected to the central shaft of the driving member for being driven by the driving member to rotate; one end of the pushing member is connected to the eccentric shaft for being driven by the eccentric shaft to rotate around the central shaft
Implementation Method 2
a guiding member, defining a guide hole; and a pushing member, wherein one end of the pushing member is connected to the eccentric shaft, and the other end of the pushing member is slidably received in and extends through the guide hole
Implementation Method 3
the massaging mechanism further includes a first bearing and a second bearing, wherein the first bearing is clamped between the rotating connection portion and the connection ring, and the second bearing is clamped between the connecting rod and the connecting member

AI summary
A massaging mechanism includes a driving member, an eccentric shaft, a guiding member and a pushing member. The driving member has a central shaft; the eccentric shaft is connected to the central shaft of the driving member for being driven by the driving member to rotate; the guiding member defines a guide hole. One end of the pushing member is connected to the eccentric shaft for being driven by the eccentric shaft to rotate around the central shaft, and the other end of the pushing member is slidably received in the guide hole for being driven by the eccentric shaft to extend and retract along an axial direction of the guide hole.
