Reciprocating Massage Head Structure for Multi-Stimulus Stimulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing massage modules, particularly those in sex toys, are limited to linear reciprocating motions, which can be difficult to manipulate and provide a limited range of stimulation.
Innovation Solution
A massage module with a massage head that can perform synchronous or asynchronous linear movement, combined with vibration and friction, and a sliding mechanism that allows for multi-stimulus massage by adjusting the length ratio of the main and vice massage portions, using a driving device to control the movement of the massage head within a shell.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If massage elements are limited to linear reciprocating motions, then the device structure is simple, but the massage effectiveness and user satisfaction are limited
Solution Approach 1:
The patent applies the dynamics principle by enabling the massage head to perform multiple motion types (linear reciprocating motion, vibration, and rotation) rather than being limited to a single linear motion. The driving device controls the massage head to execute synchronous or asynchronous combinations of these motions, transforming the static, simple motion pattern into a dynamic, multi-modal motion system that significantly enhances massage effectiveness while maintaining reasonable device complexity
Solution Approach 2:
The patent segments the massage head into functionally independent components that can execute different motion types. The massage head includes a vibration component and a rotation component that can operate independently or in combination with the linear reciprocating motion, allowing each segment to contribute to different aspects of the massage effect and enabling versatile stimulation patterns
2Force
If the massage head resists against portions of the human body during operation, then the massage force is applied, but the device becomes difficult to manipulate
Solution Approach 1:
The patent resolves the manipulation difficulty by making the massage head's motion dynamic and adaptive rather than purely forceful and static. The massage head performs vibration and rotation in addition to linear reciprocating motion, which reduces direct resistance against the body while maintaining effective massage force through oscillatory and rotational actions that are easier for the user to control and manipulate

AI summary
A massage module comprising: a head portion, a handle; and a connecting portion, the connecting portion comprising a sub-massage portion configured to providing a second stimulus to the vagina, the sub-massage portion comprising: a housing; a recess formed in the housing, the recess defining a movement space in the housing and a first opening intercommunicating the movement space inside the housing to an exterior space outside of the housing, a driving device received in a cavity defined in the handle, the cavity being communicating with the movement space; and a massage head accommodated in the movement space, wherein at least a portion of the massage head protrudes out of the movement space via the first opening, and the driving device drives the at least a portion of the massage head to reciprocating move in a linear direction in the movement space, so as to generate the second stimulus.
