Sample Carrier Elastic Support for Stoppage Vibration Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laboratory sample conveyance systems experience increased vibration when stopping, which is a limitation in achieving high-speed, large-volume, and multi-directional conveyance, particularly due to the interaction of permanent magnets with electromagnetic actuators and rotating bodies.
Innovation Solution
A sample carrier design incorporating a magnetic body with an elastic body interposed between the magnetic body and the carrier casing, allowing vertical movement, and a rotating body to facilitate smooth conveyance and reduce vibration by minimizing contact with the conveyance surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a permanent magnet is held by the sample carrier and attracted to an iron core of the electro-magnetic actuator, then the sample carrier can be moved by electromagnetic force, but vibration increases when the sample carrier is stopped
Solution Approach 1:
A rubber buffer is introduced as an intermediary element between the permanent magnet and the sample carrier body. This rubber buffer acts as a mediator that absorbs vibrations and reduces the transmission of electromagnetic forces, thereby reducing vibration when the sample carrier is stopped while still allowing electromagnetic movement
2Ease of operation
If a rotating body is provided at the bottom of the sample carrier to reduce friction, then conveyance smoothness is improved, but vibration at the time of stopping becomes more remarkable
Solution Approach 1:
A rubber buffer is introduced as an intermediary damping element between the rotating body and the sample carrier body. This rubber buffer absorbs vibrations generated by the rotating body during conveyance and especially during stopping, thereby reducing vibration while maintaining the friction-reducing benefit of the rotating body
3Productivity
If high-speed conveyance is implemented, then productivity increases, but vibration and wear increase
Solution Approach 1:
The rubber buffer acts as a vibration-absorbing intermediary that allows high-speed conveyance to occur while dampening the vibrations generated at high speeds. This enables the system to achieve high productivity without the associated vibration problems
4Device complexity
If the magnetic body is fixed rigidly to the carrier casing, then structural simplicity is maintained, but vibration cannot be reduced
Solution Approach 1:
The connection between the magnetic body and the carrier casing is changed from a rigid fixed connection to a dynamic connection using a rubber buffer. This allows the magnetic body to move vertically in response to vibrations and electromagnetic forces, thereby reducing vibration transmission while maintaining structural simplicity
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
The design significantly reduces vibration at stoppage, enabling faster transition to the next operation, reduces wear, and allows for stable, high-speed, and accurate conveyance with reduced friction and power consumption.
Implementation Method 1
an elastic body interposed between the magnetic body and a casing of the sample carrier and supporting the magnetic body, and the magnetic body is vertically movable by the elastic body
Implementation Method 2
several electro-magnetic actuators stationary arranged below the conveying plane, which move the sample carrier on top of the conveying plane by applying magnetic force to the sample carrier
Implementation Method 3
since the permanent magnet held by the sample carrier is attracted to an iron core of the electro-magnetic actuator
