Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional massagers typically only offer vibration massage functions and lack the ability to mimic human movements, making them less user-friendly and effective.
Innovation Solution
A negative pressure massager is designed with a handle containing a control board, battery, and negative pressure assembly. The assembly includes a piston part and negative pressure pipe, which generates negative pressure for massage by compressing air, allowing for more realistic and effective massage movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional massager uses only vibration motor for massage, then the device structure is simple, but the massage effect is limited and cannot mimic human movements
Solution Approach 1:
The massager is divided into functionally independent modules: vibration massage module, negative pressure massage module, and rolling massage module. Each module can operate independently or in combination, allowing versatile massage functions while maintaining manageable device complexity through modular design
Solution Approach 2:
The massager head integrates multiple massage mechanisms (vibration, negative pressure, rolling) into a single device that can perform various massage functions. The negative pressure assembly with piston part and guide structure provides suction massage capability, while the rolling assembly with rotating rollers provides kneading action, making the device universally applicable for different massage needs
2Reliability
If a negative pressure assembly is added to the massager, then the massage effect is improved, but the device complexity increases
Solution Approach 1:
The negative pressure assembly is nested within the handle structure, with the piston part moving within the negative pressure pipe. The guide structure is integrated into the assembly to guide piston movement. This nested arrangement improves massage effect through negative pressure while containing the increased complexity within a compact, organized structure
Solution Approach 2:
The piston part acts as an intermediary component that translates motor rotation into linear reciprocating motion through the guide structure. This intermediary mechanism enables negative pressure generation without requiring a complex direct-drive system, improving reliability while managing device complexity
3Speed
If the piston part moves rapidly to generate negative pressure, then the massage response is faster, but the movement stability decreases
Solution Approach 1:
The guide structure provides dynamic guidance for the piston part, allowing rapid reciprocating motion while maintaining stability through the guide rails. The guide structure adapts to the piston's movement cycle, providing support during acceleration and deceleration phases, enabling fast response with controlled stability
Solution Approach 2:
The guide structure is designed to cushion and control the piston part's movement, providing stability before and during rapid motion. The guide rails and supporting structures prepare the system for quick piston reciprocation while preventing excessive movement deviations, ensuring stable operation at high speed

Function Achieved in This Case
The negative pressure massager provides a more stable and comfortable massage experience by mimicking human movements, improving user satisfaction and effectiveness compared to traditional vibration-only massagers.
Implementation Method 1
the piston part is arranged in the negative pressure pipe and compresses air in the negative pressure chamber in a movement process to generate a negative pressure for massaging
Implementation Method 2
The rotation of the motor drives the movable rod to move up and down
