Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing chlorination systems for swimming pools, particularly electrolyzers, face limitations such as finite production capacity, electrode lifespan issues, and reduced efficiency at low temperatures, leading to inadequate chlorine production during heatwaves or high usage, with abrupt transitions between electrolysis and chemical injection.
Innovation Solution
A chlorination system that integrates electrolyzing and injecting means, controlled by a module that distributes chlorine supply based on temperature thresholds and additional parameters, ensuring a gradual transition between electrolysis and chemical injection to maintain consistent chlorine levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If electrolyzer is used for chlorine production, then chlorine is produced from salt in water, but chlorine production capacity is limited and electrodes wear out quickly at low temperatures
Solution Approach 1:
The patent combines two chlorination methods (electrolysis and chemical dosing) into a unified system that automatically selects and switches between them based on water temperature, thereby overcoming the limitations of each individual method
Solution Approach 2:
The system dynamically adjusts the chlorination method based on real-time temperature monitoring, transitioning from electrolysis at high temperatures to chemical dosing at low temperatures to optimize both productivity and reliability
2Productivity
If electrolyzer operates at low temperature, then chlorine production continues, but electrode degradation accelerates and lifespan decreases
Solution Approach 1:
The control system acts as an intermediary that monitors temperature and switches between electrolysis and chemical dosing methods, protecting electrodes from low-temperature damage while ensuring continuous chlorine production
Solution Approach 2:
The system changes the operational parameter (chlorination method) based on temperature conditions, switching from electrolysis to chemical dosing when temperature drops below the threshold to prevent electrode degradation
3Ease of operation
If abrupt switching between electrolysis and chemical dosing is used, then system response is simple, but chlorine level consistency deteriorates
Solution Approach 1:
The system implements dynamic temperature monitoring with a defined threshold range that allows smooth transition between chlorination methods, maintaining chlorine level consistency while keeping control logic relatively simple
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
Ensures consistent chlorine supply by avoiding abrupt transitions, maintaining effective disinfection despite temperature variations and high usage, extending electrode lifespan, and adapting to environmental conditions.
Implementation Method 1
The operation of the electrolyzer consists of passing an electric current between two platinum plates (electrolysis cell) in order to produce chlorine from the salt dissolved in the water

AI summary
The present invention relates to a system for chlorinating swimming pool water, comprising a control module (52) configured to distribute a quantity of chlorine Ca between electrolyzer means (21) and injector means (22), taking into account a collected temperature value Tc and temperature thresholds TMin, TMax of the pool water. In particular, the control module (52) provides a hybrid configuration, whereby, when the collected temperature value Tc is between said temperature thresholds TMin, TMax, the electrolyzer means (21) and the injector means (22) are each controlled to supply a proportion Ca1, Ca2 of said quantity of chlorine Ca. The first proportion Ca1 of the quantity of chlorine produced by said electrolyzer means (21) increases with said collected temperature value Tc.
