Double-Claw Drive Mechanism for Compact Dual-Head Kneading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing massagers with single cam structures and dual massage heads either provide insufficient massage stimulation or are bulky and complex, making them unsuitable for flexible installation in adult products.
Innovation Solution
A double-claw driving mechanism using a single driving device to achieve relative movement between two claws, enhancing massage effect while maintaining a compact design, utilizing a housing with a horizontal guide groove, a driving plate with swing arms, and a driving device for reciprocating motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dual motors are used to achieve mutual approach or separation of dual massage heads, then the massage effect is enhanced, but the structure becomes complex and bulky
Solution Approach 1:
The patent merges the functions of two independent motors into a single driving device that controls both swing arms through a shared transmission mechanism. The driving plate with swing arms at both ends allows one driving device to simultaneously control the approach and separation of two massage heads, reducing component count and structural complexity while maintaining the dual-claw massage effect
Solution Approach 2:
The driving plate serves multiple functions: it transmits power from the driving device, guides the motion of both swing arms through the guide groove, and coordinates the synchronized movement of two massage heads. This multi-functional design eliminates the need for separate motor assemblies for each massage head, simplifying the overall structure
2Reliability
If dual motors are used to achieve mutual approach or separation of dual massage heads, then the massage effect is enhanced, but the volume increases
Solution Approach 1:
By combining the driving functions into a single compact driving device that controls both swing arms through a shared transmission mechanism, the overall volume is reduced compared to using two separate motors and their associated mounting structures
Solution Approach 2:
The swing arms and massage heads are arranged in a nested configuration where the two massage heads can approach each other closely, and the driving components are integrated within a compact housing that contains the guide groove and transmission elements in a space-efficient manner

AI summary
Disclosed is a double-claw driving mechanism. The double-claw driving mechanism comprises a housing, a driving plate and a driving device; the housing is provided with a horizontal guide groove; the driving plate is arranged in the guide groove, a swing arm is installed at each of two ends of the driving plate, and a lower end of the swing arm is connected to the driving plate; and the driving device is used for driving the driving plate to reciprocate in a length direction of the guide groove, thereby driving the swing arm to swing in a reciprocating manner, and the two swing arms swing between positions close to each other and positions away from each other. When the driving plate moves horizontally in a reciprocating manner, the upper end of the swing arm is limited by the massage head or the amplitude of the swing shaft.
