Single Float Multi-Level Fluid Detection Using Orientation Sensors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for detecting fluid levels in tanks, such as those using multiple pumps with float switches or a single pump with multiple floats, are not practical for confined spaces and reduce the useful volume of the tank, and devices with large floats or rods are not suitable for tanks with reduced dimensions.
Innovation Solution
A device with a single floating body and multiple orientation sensors constrained to a fixed position, allowing for detection of different fluid levels without increasing the size of the float or tank, using a connecting protrusion for stable orientation and a command unit to manage sensor activation and deactivation based on predetermined inclinations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple floats or a large float with rod is used to detect different fluid levels, then multiple level detection capability is achieved, but the device dimensions and tank space requirements increase significantly
Solution Approach 1:
The invention divides the single float into multiple sensing zones by constraining multiple orientation sensors at different fixed positions on the float body. Each sensor detects fluid level at a specific height, segmenting the detection function across multiple sensors rather than requiring a large mechanical structure.
Solution Approach 2:
The invention transitions from a one-dimensional rod-based detection system to a three-dimensional arrangement of multiple orientation sensors positioned at different locations on the float. This spatial distribution of sensors enables multi-level detection without increasing the overall float volume.
2Reliability
If multiple pumps with float switches are used for monitoring different fluid levels, then redundancy and safety are improved, but the device complexity and space requirements increase
Solution Approach 1:
The invention merges multiple float switch functions into a single float by positioning multiple orientation sensors on one float body. This consolidation maintains the redundancy and safety of multi-level detection while eliminating the need for multiple separate pump-float systems.
Solution Approach 2:
The single float with multiple orientation sensors performs multiple detection functions simultaneously, making the device universal for monitoring different fluid levels. Each sensor contributes to the overall detection capability, allowing one device to replace multiple specialized components.
3Power
If immersion pumps are inserted into the tank for fluid movement, then pumping capability is achieved, but the useful volume of the tank for receiving fluid is reduced considerably
Solution Approach 1:
The float serves multiple functions: it provides buoyancy for the sensing system and simultaneously acts as the pumping mechanism through its movement. This eliminates the need for separate immersion pumps that would occupy tank volume, as the float itself performs the fluid movement function.
