Swimming Pool Water Leveler with Segmented Chambers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional swimming pool water leveling devices experience rapid water level fluctuations, leading to water hammer and premature wear, and are difficult to adjust and maintain, with electronic systems being expensive and aesthetically unappealing, and lacking pressure testing capabilities.
Innovation Solution
A swimming pool water leveler system with separate fill and sensing chambers, a continuous balance and overflow line, a seal valve, and a reducer plug for junk removal, allowing for pressure testing and adjustable water level settings, featuring a compact design with a small fluid passage to dampen rapid level changes and a manual adjuster for precise level control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a direct operating float valve is used, then the valve is dependable and does not cause water hammer, but the valve is difficult to replace and adjust, requiring service professionals and costly calls
Solution Approach 1:
The valve assembly is segmented into modular components that can be independently replaced. The float valve mechanism is separated from the housing, allowing the valve to be removed and replaced by pool owners without requiring service professionals. This modular segmentation maintains reliability while improving ease of operation.
Solution Approach 2:
The valve assembly is designed with user-friendly features that enable pool owners to perform maintenance and adjustments themselves. The valve includes external adjustment mechanisms and clear labeling that allow owners to replace and adjust the valve without technical expertise or costly service calls, while maintaining the dependable operation characteristic of direct operating float valves.
2Reliability
If a direct operating float valve is used, then the valve is dependable, but the secondary reservoir must be large enough to house the long operating arm
Solution Approach 1:
The operating arm is repositioned from a horizontal extension to a vertical arrangement within the reservoir. The float valve operates with the operating arm extending vertically along the reservoir wall rather than horizontally across the top, allowing the valve mechanism to be housed in a more compact reservoir volume while maintaining dependable operation.
3Volume of stationary object
If a pilot operated valve is used, then the reservoir can be smaller and less aesthetically objectionable, but the small orifices cause troublesome operation and water hammer
Solution Approach 1:
The valve system is segmented into separate functional zones: a sensing chamber with a large orifice for reliable float valve operation, and a separate fill chamber with controlled orifices. This segmentation allows the float valve to operate reliably with a large orifice while the fill chamber manages water flow through smaller orifices, preventing water hammer and troublesome operation.
Solution Approach 2:
A water seal chamber acts as an intermediary between the float valve sensing chamber and the fill chamber. This intermediate chamber receives water from the float valve through a large orifice, then delivers it to the fill chamber through controlled orifices. The water seal prevents direct connection between the high-flow sensing chamber and the precision fill orifices, eliminating water hammer while maintaining reliable operation.
4Productivity
If the water supply valve opens rapidly to fill the pool, then filling speed is improved, but water hammer occurs and valve wear increases
Solution Approach 1:
The water seal chamber provides beforehand cushioning by receiving the rapid water flow from the float valve through a large orifice, then gradually releasing it through smaller orifices to the fill chamber. This intermediate water seal absorbs the shock of rapid opening, cushioning the impact before it reaches the valve mechanism, thereby preventing water hammer and extending valve durability while maintaining fast filling speed.
5Ease of manufacture
If the balance line and overflow line are not pressure tested, then installation is simpler, but leaks can cause swelling of soil and breakage of concrete pools
Solution Approach 1:
The valve assembly incorporates built-in pressure testing capabilities that are activated during installation. Pressure test ports and connections are pre-configured in the valve assembly, allowing the balance line and overflow line to be pressure tested immediately after installation before backfilling or final connection. This preliminary action identifies leaks early, preventing soil swelling and concrete pool breakage, while the integrated design keeps the testing process simple and part of the standard installation procedure.
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 system effectively stabilizes water levels, reduces wear and water hammer, allows for easy maintenance, and provides a compact, aesthetically pleasing design with pressure testing capabilities, improving the reliability and efficiency of swimming pool water level management.
Implementation Method 1
a float valve assembly in the housing chamber that actuates a water supply valve to fill or drain the pool when the water level in the pool falls below or rises above a predetermined level, respectively
Implementation Method 2
a comparatively small housing chamber opening into the passive water line that dampens rapid water level changes in the pool
Implementation Method 3
a water supply line spout that delivers pressurized water to the valve chamber when the float valve actuates
Implementation Method 4
a cup seal and pressure seal that prevent water leakage at the water supply line connection
Implementation Method 5
Gravity causes water to flow from the valve chamber through the balance line to the pool when the float valve opens
Implementation Method 6
a reducer plug in an outlet between the sensing chamber and the balance line to assist in junk removal
