Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing massagers rely solely on internal vibration motors for single-point massage, leading to low efficiency and difficulty in simultaneously targeting multiple body parts, requiring longer usage times and reduced accuracy in finding massage points.
Innovation Solution
A gear-driven massager design featuring a housing with massage rods and gears that enable reciprocating or oscillating movements, allowing multi-point massage through gear transmission and eccentric rods, with optional vibrating motors for enhanced massage modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple vibration motor is used for massage, then the device structure is simple, but the massage coverage is limited to one point and efficiency is low
Solution Approach 1:
The patent divides the massage function into multiple independent massage rods (at least three), each capable of independent reciprocating movement. This segmentation allows simultaneous multi-point massage, dramatically improving massage efficiency and coverage area while maintaining reasonable device complexity through modular design
Solution Approach 2:
The patent transforms the static vibration motor function into dynamic reciprocating motion through gear mechanisms and eccentric rods. The massage rods perform reciprocating movements along active cavities, creating dynamic multi-point contact that enhances massage efficiency without significantly increasing overall device complexity
2Ease of operation
If a single vibration motor is used, then the device is easy to operate, but it takes longer to relax the whole body
Solution Approach 1:
By segmenting the massage function into multiple rods that operate simultaneously, the patent reduces the total time needed to cover the entire body. Users can still easily operate the device with simple button control, while the multi-rod system performs comprehensive massage in parallel, significantly reducing massage time
Solution Approach 2:
The patent ensures continuous useful action by having multiple massage rods operating simultaneously and continuously across different body points. The gear-driven mechanism maintains consistent reciprocating motion, eliminating idle time and ensuring uninterrupted massage coverage throughout the usage period
3Productivity
If multiple massage rods are added for multi-point massage, then massage efficiency improves, but device complexity increases
Solution Approach 1:
The patent uses a universal gear transmission system that drives multiple massage rods through a common mechanism. The first transmission gear connects to multiple main gears, which in turn drive multiple massage rods, allowing a single drive motor to control multiple massage points simultaneously. This multi-functionality approach improves massage efficiency while avoiding proportional increases in device complexity
Solution Approach 2:
The patent introduces intermediary transmission components (first transmission gear, main gears, second transmission gear) that mediate between the single drive motor and multiple massage rods. These intermediaries efficiently distribute power to multiple rods, enabling multi-point massage without requiring multiple independent motors, thus improving productivity while maintaining manageable device complexity
4Stability of the object's composition
If gear transmission is used to drive reciprocating motion, then massage uniformity improves, but power loss increases
Solution Approach 1:
The patent optimizes gear parameters (tooth count, module, pressure angle) and transmission ratios to minimize power loss while maintaining uniform reciprocating motion. By carefully selecting gear parameters and optimizing the transmission system, the patent achieves stable and uniform massage action with reduced energy loss, balancing massage quality and energy efficiency
