Massage Head Unit Floating Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smart wearable devices with embedded vibration motors suffer from interference and reduced comfort due to resonance and noise generation during use.
Innovation Solution
A vibration assembly featuring soft rubber base plates, massage heads, and pleated bodies that are integrally molded and designed to reduce vibration transmission to the casing, using through holes and mounting cavities to support vibrating members, allowing for independent operation and easy maintenance, and incorporating a drive control board for adaptive control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If multiple vibration motors are embedded in the same cover body, then the massage function is achieved, but the vibration motors interfere with each other causing resonance and noise
Solution Approach 1:
The patent divides the cover body into multiple independent cavity structures, with each cavity housing a separate vibration motor. This segmentation isolates the vibration sources, preventing mutual interference and reducing resonance and noise while maintaining the massage function.
Solution Approach 2:
Each cavity is designed with specific local structural features including damping materials and isolation structures tailored to each vibration motor's position. This localized design optimizes vibration control for each motor individually, reducing harmful resonance and noise effects.
2Stability of the object's composition
If vibration motors are embedded in a rigid cover body, then structural stability is maintained, but vibration transmission causes discomfort during use
Solution Approach 1:
The cover body incorporates asymmetric damping structures and varying wall thicknesses around each cavity. This asymmetric design allows selective vibration absorption and isolation, maintaining overall structural stability while reducing uncomfortable vibration transmission to the user.
Solution Approach 2:
Damping materials and isolation structures are introduced as intermediary elements between the vibration motors and the cover body. These intermediaries absorb and dissipate vibration energy, preventing direct transmission of uncomfortable vibrations while maintaining structural integrity.
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
Effectively reduces resonance and noise, enhancing user comfort by allowing the massage heads to float and adapt to the body, while maintaining efficient vibration delivery.
Implementation Method 1
the soft rubber is deformed when an external force is applied thereon, and is recovered when the external force is removed
Implementation Method 2
the vibration of the micro-vibration motor is used to massage the eye acupoints
