Swimming Pool Water Quality Sensor Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for monitoring water quality in leisure pools are inefficient due to lengthy sensor installation times and risks of leaks, with floating detectors cluttering the pool and providing incomplete water state information, and pipe-mounted sensors requiring complex installation procedures.
Innovation Solution
A device with a main body traversed by a measurement channel, featuring multiple sensors, an acquisition unit with wireless communication and independent power, and a dedicated power supply for chemical sensors, allowing for quick installation and reducing leak risks by integrating all necessary functions into a single, easily inserted assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If floating detectors are used to measure water quality, then automatic measurement is achieved, but the pool is cluttered and the device may be damaged by users
Solution Approach 1:
The measuring device is extracted from the pool water environment and relocated to the external piping system. The device is installed on the suction or discharge pipes of the filtration system, removing it from the pool interior where it could clutter or be damaged, while maintaining its measurement function through water sampling or direct pipe contact.
2Measurement precision
If sensors are placed on pool water filtration pipes, then measurement accuracy improves, but installation time increases due to individual drilling
Solution Approach 1:
Multiple sensor functions are merged into a single integrated measuring device housing. The device combines multiple measurement capabilities (pH, chlorine, temperature, etc.) in one unit that can be installed as a single component on the piping system, eliminating the need for multiple separate drilling and installation operations.
Solution Approach 2:
The measuring device is designed with multi-functionality to perform various water quality measurements simultaneously through a single installation point. The universal design allows the device to handle different measurement types without requiring separate installation procedures for each sensor type.
3Adaptability or versatility
If individual sensors are installed on pipes, then specific regulation is achieved, but leak risks increase due to multiple connection points
Solution Approach 1:
Multiple sensing functions are combined within a single sealed housing that interfaces with the piping system at one location. This consolidation reduces the number of connection points from multiple individual sensor installations to a single integrated connection, thereby reducing potential leak paths while maintaining the ability to regulate multiple water quality parameters.

AI summary
The device (10) has a main body (12) traversed by a measuring channel (13), and connecting units (14a, 14b) e.g. glue ring, for connecting the channel and a recreation basin treating circuit. Positioning and maintaining units (17a, 17c) position and maintain sensors on the body in relation with an interior of the channel. Fixation units i.e. flanges (22), fix a case (21) on the body, where the case receives an acquisition unit (20) comprising an autonomous power source with an accumulator e.g. battery.
