Wire Level Gauge for Non-Ferrous Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire level gauges are ineffective in determining the amount of wire in opaque or non-ferrous material storage containers, as they rely on magnetic attraction which fails when the container walls do not attract magnets or when the material is not ferromagnetic.
Innovation Solution
A wire level gauge comprising a measuring bar with level indicia and a magnetically attracted level indicator that slides along the outer surface of the container, allowing for accurate wire level measurement by following the leading edge of the wire as it is dispensed, adaptable to various container sizes through a detachable bracket system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a magnetic level indicator is used to measure wire level, then the measurement can be performed on ferromagnetic materials, but the method fails when the container walls or wire material are non-ferromagnetic
Solution Approach 1:
The patent introduces a ferromagnetic intermediary element (ferromagnetic wire or ferromagnetic insert) inside the storage container that acts as a mediator between the magnetic level indicator and the non-ferromagnetic wire material. This intermediary converts the non-ferromagnetic wire into a ferromagnetic interaction target, enabling the magnetic level indicator to function on non-ferromagnetic materials while maintaining measurement reliability
Solution Approach 2:
The patent changes the physical parameter of the wire by coating it with ferromagnetic material or inserting ferromagnetic elements within the wire structure. This parameter change transforms the wire from non-ferromagnetic to ferromagnetic, allowing the magnetic level indicator to detect and measure the wire level accurately without requiring the original wire material to be ferromagnetic
2Measurement precision
If the measuring bar extends from top to bottom of the container, then the full range of wire levels can be measured, but the device becomes complex and difficult to install
Solution Approach 1:
The patent segments the measuring bar into multiple detachable sections that can be assembled at different positions along the container wall. Instead of requiring a single continuous measuring bar from top to bottom, the system uses multiple shorter segments that can be independently installed and configured, reducing the complexity of installation while maintaining full measurement range capability
Solution Approach 2:
The patent introduces adjustable and movable components to the measuring bar system, allowing the measuring sections to be dynamically positioned at different heights along the container wall. This dynamic configuration capability enables the measuring bar to adapt to different container sizes and wire levels without requiring a fixed complex structure, simplifying installation while preserving measurement precision
3Ease of operation
If the level indicator is mounted on the outer surface of the container, then it can follow the wire leading edge, but it cannot penetrate through opaque container walls
Solution Approach 1:
The patent uses a ferromagnetic intermediary element (ferromagnetic wire or ferromagnetic insert) as a mediator that extends through the opaque container wall. The magnetic level indicator mounts on the outer surface and interacts with this intermediary element, which transmits the magnetic field through the opaque wall material, enabling the indicator to follow the wire leading edge despite the container wall's opacity
Solution Approach 2:
The patent replaces direct mechanical contact or optical viewing through the container wall with a magnetic field-based interaction system. The magnetic level indicator uses magnetic attraction to follow the ferromagnetic intermediary element through the opaque wall, substituting mechanical/optical limitations with magnetic field penetration capability, allowing operation without transparent container walls
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
Enables precise measurement of wire levels in containers with non-ferrous materials by using a magnetically attracted level indicator that moves along the measuring bar, providing clear indicia for wire quantity, even when the container walls do not attract magnets, and is versatile for different container sizes.
Implementation Method 1
The magnetic attraction between the magnet of the level indicator and the ferromagnetic material of the wire moves the level indicator along the measuring bar as the level indicator follows the leading edge of the wire
