Pool Aerator Valve Sealing Cover for Watertight, Abrasion-Safe Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional caps and plugs for swimming pool aerator valves fail to provide a consistent watertight seal, leading to water and debris infiltration and damage to pool systems due to abrasion and tearing of pool covers by grip-aiding protrusions.
Innovation Solution
A protective sealing cover with a compressible elastic plug and cap, designed to form a watertight seal over the aerator valve, minimizing abrasion and tearing by using a flat outer surface and enclosing the flange, preventing water and debris entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional caps with grip-aiding protrusions are used, then ease of operation is improved, but the pool cover is abraded and torn due to friction
Solution Approach 1:
The patent introduces a smooth outer surface on the cap as an intermediary between the grip-aiding protrusions and the pool cover. This mediator allows users to grip the cap for installation and removal while preventing direct contact between protrusions and the pool cover, thereby eliminating abrasion and tearing.
2Reliability
If rubber ring seals are used in conventional caps, then watertight sealing is improved, but the seal deteriorates or fails to tighten properly compromising the seal
Solution Approach 1:
The patent changes the material parameter from conventional rubber ring to elastomeric material, which provides superior elasticity and durability. This material parameter change ensures consistent sealing pressure over time while resisting deterioration, maintaining reliable watertight sealing throughout the winterization period.
3Strength
If conventional rigid caps are used, then structural strength is improved, but the cap abrades and tears the pool cover through friction
Solution Approach 1:
The patent applies local quality by differentiating the surface characteristics of the cap. The outer surface is designed to be smooth to prevent abrasion of the pool cover, while the inner surface retains structural strength and rigidity for proper installation and sealing. This localized differentiation resolves the contradiction between strength and abrasion resistance.
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 ensures a reliable watertight seal, protecting the pool system from moisture and debris while preventing abrasion of pool covers, thus maintaining pool integrity and functionality.
Implementation Method 1
The plug is formed of a compressible elastic material such as PVC, and is adapted to be inserted through the aperture to create a watertight seal

AI summary
A protective sealing cover for a swimming pool aerator valve comprising a cap and a plug formed from a compressible elastic material, the aerator valve is embedded within a planar surface and has a bore portion, an aperture providing access to the bore portion, and a flange surrounding the aperture, the plug is adapted to form a watertight seal with the aperture to prevent water and debris from entering the bore portion, the cap has an inner surface and cap recess adapted to fully enclose the flange such that the inner surface rests against the planar surface, the cap further having a flat outer face which forms a non-abrasive surface.
