Buoyant Gas Sensor Housing for Fluid Surface Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gas sensors face delays and increased exposure risks when detecting gases in fluid environments due to the need for remote placement, which can lead to hazardous situations for operators.
Innovation Solution
A buoyant housing system for gas sensors that includes a pump and watertight inlets and outlets, allowing the gas sensor to float above the fluid surface, enabling direct gas evaluation and reducing exposure time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If gas sensors are placed remotely in fluid environments, then operators are protected from direct exposure, but detection time increases and exposure risks remain
Solution Approach 1:
The housing incorporates buoyancy elements that counteract the weight of the gas sensor assembly, enabling it to float on fluid surfaces. This allows the sensor to be positioned directly at the fluid surface for immediate detection while operators remain safely remote, resolving the contradiction between operator protection and detection speed.
2Loss of time
If gas sensors are placed directly in fluid environments, then detection time is reduced, but fluid ingress can damage the sensor
Solution Approach 1:
The housing employs sealing membranes that create a watertight barrier between the fluid environment and the gas sensor components. These flexible sealing elements prevent fluid ingress while allowing the sensor to operate directly at the fluid surface, enabling immediate detection without compromising sensor durability.
3Reliability
If gas sensors are placed remotely, then fluid damage is prevented, but detection accuracy near the fluid surface is reduced
Solution Approach 1:
The invention merges the gas sensor with a buoyant housing assembly that includes pumping mechanisms and sealing membranes. This integration allows the sensor to be positioned directly at the fluid surface for accurate detection while the housing provides protective sealing, combining the benefits of both remote protection and close-proximity detection.
4Ease of operation
If a buoyant housing is added to the gas sensor, then the sensor can float on fluid surfaces, but device complexity increases
Solution Approach 1:
The buoyant housing serves multiple functions simultaneously: it provides buoyancy to float the sensor on fluid surfaces, incorporates sealing membranes to prevent fluid ingress, includes pumping mechanisms for gas delivery, and offers structural protection. This multi-functionality reduces the need for separate components, making the overall system more manageable despite the added capabilities.
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 buoyant housing system allows for immediate and accurate gas detection near the operator, reducing exposure time and preventing damage from fluid ingress, thus enhancing safety and efficiency.
Implementation Method 1
the buoyant housing may be configured such that at least a portion of the buoyant housing floats above a surface of the fluid
Implementation Method 2
The pump may be configured to cause gas received by the inlet opening to be directed to the gas sensor for evaluation

AI summary
Devices, assemblies, and associated methods are provided for gas sensors. An example device for use with a gas sensor includes a buoyant housing that receives the gas sensor therein, an inlet opening defined by the housing, a pump positioned within the housing, and an outlet opening. The pump is in fluid communication with the inlet opening and the gas sensor in an instance in which the gas sensor is received by the housing. The pump is configured to cause gas received by the inlet opening to be directed to the gas sensor for evaluation, and the outlet opening is configured to discharge gas exiting the gas sensor from the buoyant housing. In an operational condition in which the device is placed in a fluid, the buoyant housing is configured such that at least a portion of the buoyant housing floats above a surface of the fluid.
