Automated Chlorine Dosing System for Pool Water Treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water treatment systems for pools and spas lack responsiveness to changes in water characteristics, requiring manual adjustments and posing safety risks due to direct handling of chlorine solutions, and they do not efficiently manage the levels of chlorine and other water parameters.
Innovation Solution
A system that measures water characteristics using sensors and adjusts the chlorine levels by dosing inactive ingredients, such as water, into a dispenser containing active ingredients like chlorine, eliminating the need for handling hazardous solutions and allowing for better control and extended life of chlorine, while also alerting users when replenishment is needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual adjustment of selector valve is used to control chlorine flow, then system simplicity is maintained, but responsiveness to water characteristic changes deteriorates
Solution Approach 1:
The system uses sensors to automatically detect water characteristics (chlorine levels, pH) and triggers the dispenser to release chlorine tablets or granules without manual intervention. The controller autonomously manages the dispensing process based on sensor feedback, eliminating the need for manual selector valve adjustments while maintaining system simplicity.
Solution Approach 2:
The patent replaces manual mechanical adjustment of the selector valve with an automated electronic control system. Sensors detect water characteristics and send signals to the controller, which then actuates the dispenser mechanism automatically, substituting human-operated mechanical control with sensor-based electronic control for improved responsiveness.
2Manufacturing precision
If liquid chlorine solutions are handled directly for dosing, then precise chlorine level control is achieved, but safety risks increase due to direct handling of hazardous materials
Solution Approach 1:
The system uses disposable chlorine tablets or granules contained in replaceable cartridges rather than handling liquid chlorine solutions. The solid chlorine dispersants are enclosed in safe containers that are replaced when depleted, eliminating the need for users to handle hazardous liquid chlorine while maintaining effective chlorine dosing.
Solution Approach 2:
The patent introduces an intermediary mechanism - the solid chlorine tablet dispenser system - that mediates between the user and the chlorine source. Instead of directly handling liquid chlorine, users interact with a safe dispensing system that automatically releases measured amounts of chlorine, acting as a protective intermediary between human operators and hazardous materials.
3Reliability
If continuous chlorine dispensing is used to maintain chlorine levels, then consistent water treatment is achieved, but chlorine consumption increases reducing its effective life
Solution Approach 1:
The system uses periodic dosing instead of continuous dispensing. Sensors monitor chlorine levels and trigger the dispenser to release chlorine tablets or granules only when levels fall below a threshold. This on-demand periodic action maintains consistent water treatment while minimizing unnecessary chlorine consumption and extending the effective life of chlorine supplies.
Solution Approach 2:
The patent implements a feedback control system where sensors continuously monitor water characteristics (chlorine levels, pH, temperature) and provide feedback to the controller. Based on this feedback, the controller adjusts the dispensing timing and amount, releasing chlorine only when and where needed. This closed-loop feedback mechanism ensures consistent water treatment while optimizing chlorine usage and reducing waste.

AI summary
A system for sensing and measuring water characteristics or an external factor and initiating controlling the water characteristics of the body of water which may be based on external factor where the controlling of the water characteristics can be achieved through dosing or nondosing of an inactive material through an active material or dosing both an active material and an inactive material in the body of water in response to measured levels of water characteristics to enable the water to be used for either internal or external use in controlling harmful organisms.
