Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Suction pool/spa cleaners face operational inefficiencies when used with variable speed pumps, as they require precise pressure settings to avoid damage and ensure proper function, and existing manual setups are cumbersome and prone to errors.
Innovation Solution
The introduction of an improved flow control valve assembly that automatically regulates suction flow to the cleaner, maintaining optimal operating conditions by shifting fluid flow based on pump speed changes, ensuring the cleaner operates correctly at varying pump speeds without manual adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a variable speed pump is used to circulate pool water, then energy efficiency and pump flexibility are improved, but the suction pressure becomes variable which can cause damage to the suction cleaner or improper operation
Solution Approach 1:
A flow control valve assembly is introduced as an intermediary device between the variable speed pump and the suction cleaner. This valve automatically regulates the flow of pool water to the cleaner, ensuring that the cleaner receives adequate flow even when the pump operates at lower speeds. The valve acts as a mediator that decouples the variable pump output from the cleaner's fixed flow requirements, allowing the pump to vary speed for energy efficiency while maintaining reliable cleaner operation.
2Ease of operation
If manual flow control setup is used, then some flow regulation is achieved, but the system is cumbersome and prone to errors requiring frequent adjustments
Solution Approach 1:
The flow control valve assembly is designed to automatically regulate flow without requiring manual intervention. The valve contains internal mechanisms that self-adjust the flow of pool water to the suction cleaner based on system conditions. This eliminates the need for users to manually adjust valves or monitor flow settings, making the system easier to operate while reducing the complexity of manual adjustment procedures. The device serves itself by maintaining proper flow conditions automatically.
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 flow control valve assembly maintains the suction cleaner within designed operating parameters, preventing damage and ensuring proper operation at both lower and higher pump speeds, eliminating the need for manual adjustments and reducing wear on cleaner parts.
Implementation Method 1
The flow control valve assembly automatically regulates flow to the cleaner, thereby providing regulated flow to the cleaner so that if the suction cleaner remains in the water (e.g., during a lower pump speed setting), when the pump is later operated at a higher speed the suction cleaner will function/move as designed.

AI summary
Improved flow control valve assemblies for fluid systems (e.g., pools or spas) are provided. Advantageous flow control valve assemblies for pool/spa cleaners (e.g., suction pool/spa cleaners) are provided. The present disclosure provides for flow control assemblies for suction pool/spa cleaners, with the cleaners utilized in conjunction with a variable speed pump. A manual valve set-up can be removed from the system, and an advantageous flow control valve assembly can be provided to automatically regulate the flow/suction to the cleaner. The improved flow control valve assembly thereby provides regulated flow to the cleaner, so that if the cleaner remains in the water at low pump speeds, when the pump is later operated at a higher speed the cleaner will function as designed. When there is flow/suction below the desired operating parameters of the cleaner, the pump will operate as desired, and the cleaner is stationary.
