Swimming Pool Flowmeter Safety Vacuum Release System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Swimming pool drains pose a significant risk of entrapment and drowning due to strong suction forces, with existing safety measures only addressing the issue after suction has developed, lacking a method to prevent suction from occurring in the first place.
Innovation Solution
A swimming pool flowmeter with a rotor that monitors and measures the flow rate of water in the drain pipe, triggering the pump to shut off if the flow rate drops below a predetermined level to prevent entrapment and maintaining efficient water recirculation by using a check valve function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the pump operates at high power to maintain efficient water recirculation, then the swimming pool is maintained clean, but strong suction forces are generated that can entrap and drown persons
Solution Approach 1:
The flowmeter continuously monitors water flow rate before entrapment can occur, and the control system preemptively shuts off the pump when flow rate drops below a predetermined threshold, preventing dangerous suction forces from developing in the first place
Solution Approach 2:
The flowmeter provides real-time feedback on water flow rate to the control system, which automatically adjusts pump operation by shutting off the pump when abnormal flow conditions indicate potential blockage or entrapment risk
2Object-affected harmful factors
If the pump shuts off immediately when flow rate drops to prevent entrapment, then safety is improved, but pump operation time is reduced which may affect pool maintenance quality
Solution Approach 1:
The flowmeter provides continuous real-time feedback on water flow rate, enabling the control system to monitor pump performance and shut off the pump only when abnormal conditions are detected, thereby maintaining safe operation duration while preventing entrapment
3Object-affected harmful factors
If a flowmeter and control system are installed to monitor flow rate and prevent entrapment, then safety is improved, but device complexity increases
Solution Approach 1:
The flowmeter is designed to automatically monitor flow rate and trigger pump shutdown without requiring external intervention or complex control logic, allowing the system to self-regulate based on flow conditions
Solution Approach 2:
The flowmeter extracts and measures only the critical flow rate parameter from the complex pump system, providing a simple scalar value that directly controls pump operation through the control system
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
Prevents the development of dangerous suction forces at the drain by continuously monitoring flow rates, ensuring immediate cessation of suction when blockages occur, thereby reducing the risk of injury or drowning and optimizing pump operation.
Implementation Method 1
a rotor that rotates at a velocity that is proportional to the flow rate of water within the swimming pool drain pipe
Implementation Method 2
maintaining efficient water recirculation by using a check valve function

AI summary
The flowmeter of the present invention is primarily used in swimming pools and is configured to deactivate a swimming pool pump when the drain in the swimming pool is blocked or covered. Swimming pool drains are often blocked or covered by the body of a swimmer. When the drain is blocked or covered, the pump creates substantial suction force that entraps the body of a swimmer against the drain. By deactivating the pump when the drain is blocked or covered, the flowmeter of the present invention serves as a safety vacuum release system that prevents entrapment of a person by the drain of the swimming pool.
