Reciprocating Massager Drive Assembly for Hands-Free Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing massage technologies, such as massage bars and cylinders, require manual operation, leading to hand fatigue and discomfort.
Innovation Solution
A hands-free massager design featuring a massaging member, an outer shell with an accommodating cavity, and a driver with a reciprocating displacement drive assembly. The driver includes a motor, rotating member, and reciprocating displacement member, which work together to perform a reciprocating telescopic motion of the massaging member, allowing for automatic massage without manual operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation of massage bars and cylinders is used, then the massage function is achieved, but hand fatigue and discomfort occur
Solution Approach 1:
The massaging member is designed to perform massage automatically through a drive assembly that enables reciprocating telescopic motion, allowing the device to serve itself without requiring continuous manual operation. The motor-driven mechanism autonomously moves the massaging member between extended and retracted positions to provide continuous massage therapy.
Solution Approach 2:
The patent replaces the manual mechanical operation system with an automated motor-driven system. The drive assembly includes a motor, drive wheel, and transmission mechanism that convert rotational motion into reciprocating linear motion, substituting human hand operation with an automated mechanical system.
2Extent of automation
If hands-free automatic massage is implemented, then hand fatigue is eliminated, but device complexity increases
Solution Approach 1:
The drive assembly components are nested within the outer shell structure. The motor, drive wheel, and transmission mechanisms are arranged in a compact nested configuration where smaller components are housed within or alongside larger structural elements, reducing overall device complexity and space requirements.
Solution Approach 2:
The patent utilizes the telescopic dimension of the massaging member to achieve automatic massage. By adding the reciprocating motion dimension (extension and retraction along the longitudinal axis), the system provides hands-free operation without requiring complex multi-axial mechanisms, as the massaging action is achieved through the telescopic movement combined with rotation.

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 massager effectively reduces hand fatigue by enabling automatic massage, improving comfort and service performance by allowing continuous operation without manual intervention.
Implementation Method 1
a motor, a rotating member and a reciprocating displacement member, the reciprocating displacement member is at least partially slidably connected with an inner wall of the accommodating cavity
Implementation Method 2
the reciprocating displacement member is at least partially slidably connected with an inner wall of the accommodating cavity

AI summary
The present invention discloses a massager, where an outer shell includes an accommodating cavity; and a driver is mounted in the accommodating cavity, the driver includes a reciprocating displacement drive assembly and a mounting portion, a connecting portion of the reciprocating displacement drive assembly penetrates a long-shaped guide hole on the outer shell and is connected with the mounting portion, and the massaging member is at least partially connected with the mounting portion in a plug-in manner, so that the reciprocating displacement drive assembly drives the mounting portion to perform a reciprocating linear displacement action to cause the massaging member to perform a reciprocating telescopic motion. It solves the technical problem of hand fatigue due to massage with hands, thereby improving service performance.
