Magnetic Level Indicator with Stop Plates for Accurate Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional magnetic level indicators experience excessive rotation of magnetic boards due to rapid movement of the magnetic float, leading to inaccurate liquid level indications.
Innovation Solution
A magnetic level indicator with a fixed base and pivotally arranged magnetic elements, featuring stop plates and a block portion to prevent excessive rotation, ensuring accurate visual indication by exposing the first surface with a specific indication mark while blocking the second surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the magnetic float moves rapidly to track liquid level changes, then the response speed is improved, but the magnetic boards rotate excessively causing wrong indication marks
Solution Approach 1:
The stop plates are pre-positioned on the magnetic boards at specific distances from the rotation axis. This preliminary positioning ensures that when rapid rotation occurs, the stop plates will engage with the block portions before the magnetic boards can rotate past the correct indication mark, preventing wrong indications from the outset
Solution Approach 2:
The stop plates act as intermediary elements between the magnetic float and the indication marks. They mediate the rotation process by providing a mechanical stop that limits the range of motion, ensuring that even when the magnetic float moves rapidly, the magnetic boards rotate only to the correct position and not beyond

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 solution provides accurate, convenient, and efficient visual indication of liquid levels in tanks by preventing excessive rotation and ensuring only the intended indication mark is exposed, enhancing the reliability of the magnetic level indicator.
Implementation Method 1
the magnetic float is close to the magnetic element, each magnetic element is rotated by magnetic attraction of the magnetic float to expose the first surface

AI summary
A magnetic level indicator includes a fixed base and a plurality of magnetic elements. The fixed base includes two lateral plates corresponding to each other, a block portion extending from a bottom edge of each of the two lateral plates and an installation space between the two lateral plates. The magnetic elements are pivotally arranged in the installation space and are arranged along an extension direction of each lateral plate. Each of the magnetic elements includes a first surface and a second surface corresponding to each other and includes two stop plates placed corresponding to each other between the first surface and the second surface. The first surface includes a first indication mark, and the second surface includes a second indication mark different from the first indication mark.
