Massage Head Transmission Element for Vibration Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing massage and cleaning devices often cause unpleasant skin vibration due to direct transmission of drive element movement, which can detract from the desired massage or cleaning effect.
Innovation Solution
The massage head incorporates a transmission element that oscillates indirectly, using a receiving element connected to the housing, allowing for superimposed movement processes and chaotic patterns that enhance the massage or cleaning effect without direct contact between the drive element and massage element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the drive element directly drives the massage element, then the structure is simple, but the user experiences unpleasant skin vibration that reduces massage effectiveness
Solution Approach 1:
The patent introduces a transmission element as an intermediary between the drive element and the massage element. This transmission element converts the oscillating movement of the drive element into a different type of movement that drives the massage element, thereby eliminating the direct transmission of harmful vibrations to the user's skin while maintaining structural efficiency
2Productivity
If the drive element directly drives the massage element, then the movement transmission is efficient, but the massage effect is reduced due to uniform and predictable movement patterns
Solution Approach 1:
The transmission element acts as a mediator that transforms the uniform oscillating movement into a more complex movement pattern for the massage element, improving massage effectiveness without sacrificing transmission efficiency
Solution Approach 2:
The patent utilizes vibration principles by introducing a transmission element that creates complex movement patterns including vibrational components. This transforms the simple oscillating movement into a multi-frequency movement that enhances the massage effect on the user's skin
3Object-affected harmful factors
If a transmission element is introduced to improve massage effect, then the massage effectiveness is enhanced, but the device complexity increases
Solution Approach 1:
The transmission element is designed as a simple intermediary component that can be integrated into the existing device structure. It effectively transforms movement patterns without requiring complex mechanisms, thus improving massage effectiveness while minimizing the increase in device complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This indirect drive system creates a more effective massage or cleaning experience by generating vibrations with different frequencies and resonance, resulting in a chaotic movement pattern that improves user comfort and efficacy.
Implementation Method 1
The transmission element, which can be oscillating in a translatory manner, is not in direct contact with the receiving element and the massage element
Implementation Method 2
The oscillating movement of the transmission element driven by the at least one drive element of the handle part causes vibrations in the housing when transmitted to the housing of the massage head with a different frequency or with a phase shift and possibly resonance vibrations that overlay the oscillating movement
