Vented Dock Float Pentane Gas Pressure Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Floating docks filled with polystyrene can experience deformation due to the buildup of Pentane gas, which increases pressure and causes expansion, as existing technologies lack an effective venting mechanism to manage this issue.
Innovation Solution
A vented dock float design featuring a flange with a neck and plug system that allows for ventilation of the interior housing, enabling the release of Pentane gas while maintaining a sealed environment to prevent water or debris ingress, utilizing a spin-welded connection and a retaining mechanism for the plug.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the dock float interior is filled with polystyrene to prevent deformation and maintain buoyancy, then the structural integrity and buoyancy are improved, but Pentane gas builds up pressure causing expansion and deformation
Solution Approach 1:
The plug is divided into functional segments: a shaft with venting passage for gas release, a sealing member for closing the passage, and a handle for operation. This segmentation allows the single component to perform multiple functions: venting Pentane gas when needed while maintaining structural integrity when sealed
Solution Approach 2:
The venting passage in the shaft allows dynamic control of gas pressure parameters. By adjusting the plug position (venting or sealed), the internal pressure parameter can be changed to prevent harmful expansion while maintaining buoyancy
2Object-affected harmful factors
If a venting mechanism is added to release Pentane gas, then the harmful gas pressure is reduced, but the device complexity increases with additional components
Solution Approach 1:
Multiple functions are merged into the plug component: the shaft provides structural support and contains the venting passage, the sealing member provides the sealing function, and the handle provides operational control. This merging reduces overall device complexity compared to having separate components for each function
Solution Approach 2:
The plug serves multiple purposes: it acts as a structural element connecting to the flange, provides venting capability through its passage, offers sealing when needed, and includes a handle for user operation. This multi-functionality reduces the need for additional separate components
3Object-affected harmful factors
If the plug is fully sealed to prevent water or debris ingress, then protection from external materials is improved, but Pentane gas cannot be vented causing pressure buildup
Solution Approach 1:
The plug transitions between static sealed positions and dynamic venting positions. The venting passage allows the system to dynamically adjust between sealed and vented states, enabling the float to respond to changing internal pressure conditions while maintaining protection from water and debris
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 solution effectively reduces the risk of deformation by venting Pentane gas, maintaining buoyancy, and preventing damage from external materials, thereby enhancing the stability and longevity of the dock float.
Implementation Method 1
a float member for displacing a liquid to produce buoyancy
Implementation Method 2
The shaft may have a venting passage formed along at least a portion thereof for permitting ventilation of the interior of the hollow housing when the plug is in a venting position
Implementation Method 3
a sealing member operably positioned around the shaft beneath the handle for sealing the access passage when the plug is in the sealing position
Implementation Method 4
The planar member is sealedly attached to the exterior wall of the housing by spin-welding

AI summary
A vented dock float and a method for providing one are provided. The dock float comprises a housing having a venting hole, a flange having a neck aligned with the hole, and a plug having a venting passage for controlling ventilation of the housing interior. The flange is spin-welded onto the exterior wall of the dock float at the venting hole. The float is then filled with light material through the flange neck. The plug having a venting passage is inserted in the neck in a non-sealing position for allowing gas trapped inside the dock float to vent out. Once the majority of the gas is vented out, the plug is moved to a sealing position to seal the dock float interior.
