Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional in-floor pool cleaning systems experience increased wear and tear on equipment and piping due to repeated shutting off and turning on of water pressure in different zones, leading to valve hammering and reduced system efficiency.
Innovation Solution
A controller valve system with a hydro-valve and distribution valve configuration that intelligently controls water flow to multiple zones, using a microcontroller to manage the position of a pausing arm and hydro-valve, allowing customized sequences, durations, and cycles, and includes a controller valve with a bypass water outlet to manage pressure differentials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If water pressure is repeatedly shut off and turned on in different zones, then each cleaning head can complete its cleaning cycle in each zone, but increased wear and tear occurs on equipment and piping and valve hammering results
Solution Approach 1:
The system pre-pressurizes the water supply line before switching to a different zone. The controller valve maintains water pressure in the supply line and uses a bypass passage to gradually equalize pressure before zone switching, preventing water hammer and reducing wear on valves and piping while enabling continuous cleaning cycles across multiple zones
Solution Approach 2:
A bypass passage with a bypass valve serves as an intermediary element between the water supply line and the distribution valve. This bypass system allows gradual pressure equalization by diverting water flow through the bypass passage, mediating the pressure differential that would otherwise cause water hammer when switching between zones
2Adaptability or versatility
If water pressure is turned off and on to switch between zones, then zone switching is achieved, but hammering of the valve occurs from repeated shutting off and turning on
Solution Approach 1:
The controller valve pre-pressurizes the supply line through the bypass passage before zone switching occurs. By gradually equalizing pressure in advance, the system prevents the sudden pressure changes that cause valve hammering, allowing smooth zone transitions without damaging the distribution valve or piping
Solution Approach 2:
The bypass passage acts as an intermediary pressure equalization path. It gradually balances the pressure differential between zones before the distribution valve switches, serving as a mediator that prevents direct pressure shocks to the valve mechanism and eliminates hammering effects
3Ease of operation
If conventional control valve is used with single or multiple ports, then water can be supplied to cleaning zones, but increased wear and tear on equipment and piping occurs
Solution Approach 1:
The controller valve maintains continuous water pressure in the supply line by using a bypass passage to gradually equalize pressure before zone switching. This preliminary pressure equalization prevents sudden pressure changes that cause wear on the pump, valves, and piping, while still enabling easy switching between different cleaning zones
Solution Approach 2:
The bypass passage with bypass valve serves as an intermediary system that protects the main water distribution components from wear. It gradually balances pressure before zone transitions, acting as a buffer that prevents direct pressure shocks to the pump and piping, thereby extending equipment life while maintaining operational ease

AI summary
A pool control system with a controller valve, a distribution valve, and a microcontroller. The controller valve has a primary water outlet and a bypass water outlet. The controller valve is configured to move between an open configuration in which the water passes from a water inlet to the primary water outlet and a closed configuration in which the water passes from the water inlet to the bypass water outlet. The distribution valve has an inlet port fluidly coupled to the primary water outlet and a plurality of outlet ports with an outlet port aperture. The outlet port aperture is configured to align with a new outlet port each time the controller valve moves from the open configuration to the closed configuration. The microcontroller is configured to discharge water from the pool control system by controlling the controller valve to change the configuration between the open and closed configurations.
