Voice Operation Device Fixing Mechanism for Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing material testing machines face issues with vibration transmission from the machine column to the microphone, leading to noise interference and potential failure in voice recognition processing during operations like crosshead movement.
Innovation Solution
A fixing mechanism is introduced that uses three or more elastic bodies in contact with the machine column and a magnet body in non-contact to absorb and suppress vibrations, ensuring that the voice operation device is securely attached while minimizing vibration transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the microphone is fixed directly to the machine column, then the voice operation device can be securely mounted, but vibration from the crosshead movement is transmitted to the microphone causing noise and recognition failure
Solution Approach 1:
The patent introduces an intermediary fixing mechanism between the machine column and the voice operation device. This intermediary structure includes elastic elements and magnetic components that decouple the direct mechanical connection, allowing the microphone to be isolated from vibration sources while maintaining secure mounting. The intermediary mechanism absorbs and dampens vibrations before they reach the microphone, resolving the contradiction between secure mounting and vibration isolation.
2Strength
If a rigid fixing structure is used to secure the voice operation device, then the device is firmly attached, but vibration transmission to the microphone increases
Solution Approach 1:
The patent changes the physical parameters of the fixing mechanism by incorporating elastic elements with specific elasticity coefficients and magnetic components with controlled magnetic force. These parameter adjustments allow the fixing mechanism to provide sufficient holding strength while simultaneously reducing vibration transmission. The elastic elements deform under vibration, absorbing energy, while the magnetic components provide consistent attraction force, achieving both strength and vibration isolation through parameter optimization.
