Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing swimming pool automation dispensing systems struggle with inconsistent pool chemistry control, frequent maintenance, release of undissolved chlorine particles, and high maintenance needs due to complex electronics and machinery.
Innovation Solution
An automated swimming pool chemical dispensing system with a spin-down sediment filter that ensures chlorine is fully dissolved before release, using a novel upside-down orientation and multiple water lines to break up and dissolve particles, and a simplified design with fewer components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing swimming pool automation dispensing systems use ORP/pH measurement to control chlorine dispensing, then pool chemistry control is attempted, but the systems suffer from frequent fluctuations in readings and failures to maintain chemistry at required levels, requiring frequent cleaning and calibration
Solution Approach 1:
The patent removes the problematic ORP/pH sensors and their associated measurement systems from the pool chemistry control process. Instead of measuring and reacting to fluctuations, the system directly maintains chemistry by dispensing chlorine at scheduled intervals, eliminating the need for frequent sensor cleaning and calibration while achieving consistent chemistry control.
Solution Approach 2:
The system automatically dispenses chlorine based on predetermined schedules and pool parameters without requiring manual intervention for monitoring or adjustment. The automated dispensing mechanism maintains chemistry consistency through self-regulated operation, reducing the need for human maintenance activities.
2Productivity
If slow dissolve feeders using CCH tablets are used to dispense chlorine, then chlorine is delivered continuously, but undissolved chlorine particulate matter is released into the pool causing chlorine waste
Solution Approach 1:
The patent changes the physical state and dissolution parameters of chlorine delivery by using rapidly dissolving chlorine granules instead of slow-dissolving tablets. The system controls the dispensing rate and water interaction to ensure complete dissolution before pool entry, eliminating particulate matter release while maintaining continuous chlorine delivery through automated scheduled dispensing.
Solution Approach 2:
The system introduces an intermediary dissolution chamber or water stream that completely dissolves chlorine granules before they enter the pool. This intermediate step ensures thorough mixing and dissolution, preventing undissolved particles from reaching the pool water while maintaining continuous chlorine delivery.
3Extent of automation
If automated dispensing systems use large stands, complicated electronics and machinery with more parts, then automation functionality is achieved, but maintenance needs increase frequently
Solution Approach 1:
The patent removes complicated electronics, large stands, and excessive machinery from the automated dispensing system. It retains only the essential automation components needed for scheduled chlorine dispensing, significantly reducing the number of parts that require maintenance while preserving core automation functionality.
Solution Approach 2:
Instead of adding complex sensors and control systems to achieve automation, the patent simplifies the approach by using basic timed dispensing mechanisms with minimal electronics. The system inverts the conventional wisdom that more components equal better automation, demonstrating that fewer components can achieve the same automation goal with reduced maintenance needs.
