Pool Pump Automatic Exhaust Mechanism Using a Buoy Valve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pool pumps require manual operation of a relief valve to release air, which can lead to issues such as stuck or cross-threaded screws, degradation over time, and the need for frequent replacements.
Innovation Solution
A pool pump design featuring a buoy room system with a buoy and buoy room valve that automatically releases air without manual operation, using a chamber and seals to manage gas and liquid flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a manual relief valve with screw is used to release air, then air can be vented from the pump, but the screw may be stuck, cross-threaded, or degrade over time requiring replacement
Solution Approach 1:
The buoy automatically activates the relief valve mechanism when air accumulates in the pump housing. The buoy rises with accumulated air and mechanically triggers the valve to open, eliminating the need for manual operation and preventing screw degradation from repeated manual turning.
Solution Approach 2:
The patent replaces the manual screw-based relief valve system with an automatic buoy-driven mechanical system. The buoy's movement converts air accumulation into automatic valve activation, substituting the need for manual screw operation with an automated mechanical response.
2Extent of automation
If manual operation of relief valve is required, then air release can be controlled, but frequent manual intervention reduces convenience and increases maintenance
Solution Approach 1:
The buoy-based system provides self-service air release functionality. When air accumulates in the pump housing, the buoy automatically rises and activates the relief valve without requiring user intervention. The system monitors and responds to air accumulation autonomously, eliminating the need for frequent manual checking and operation.
3Productivity
If the pump operates with trapped air, then continuous operation is maintained, but air disrupts liquid flow and damages the impeller
Solution Approach 1:
The buoy serves as a feedback mechanism that detects air accumulation in the pump housing. When air reaches a certain level, the buoy rises and triggers the relief valve to open, automatically releasing the air. This feedback loop prevents air from reaching levels that would disrupt liquid flow or damage the impeller, maintaining continuous productive operation.
Solution Approach 2:
The buoy-based relief valve system activates before air accumulation reaches harmful levels. By detecting and responding to air presence early through the buoy's rise, the system preemptively releases air, preventing the conditions that would lead to liquid flow disruption or impeller damage.

Function Achieved in This Case
The automatic air release system enhances convenience and longevity by reducing manual intervention and minimizing component failure, while also preventing debris from entering the pump.
