Solution Overview

Problem

The high cost of maintaining two separate power sources for sanitizing swimming pools and spas, which often have a large volume disparity, results in increased installation and maintenance costs due to the need for distinct equipment and power supplies for each.

Innovation Solution

A single power source system that connects to both a pool and a spa through a circulation system, using a control system to selectively deliver electric current to sanitizer generators, ensuring sanitizer concentration is maintained at desired levels in both bodies of water, thereby reducing costs by up to 42%.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If two separate power sources are used for pool and spa sanitization, then each body of water receives adequate sanitizer generation, but installation and maintenance costs increase significantly

Engineering Contradiction:
Improvesanitizer generation reliabilityVSAvoidpower source configuration
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines two separate power sources into a single power source that serves both the pool and spa sanitization systems. The controller intelligently distributes electrical current to either the pool sanitizer generator or the spa sanitizer generator based on which body of water requires sanitization, eliminating the need for two separate power sources while maintaining adequate sanitizer generation for both bodies of water.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The single power source is designed to perform multiple functions by serving both the pool sanitization system and the spa sanitization system. The controller enables the power source to switch between different loads (pool generator or spa generator) based on operational requirements, making the power source universal for both sanitization applications.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Device complexity

If a single power source serves both pool and spa, then installation and maintenance costs are reduced, but the system must selectively manage current distribution to maintain sanitizer levels

Engineering Contradiction:
Improvepower source configurationVSAvoidcurrent distribution control
Core Design Contradiction:
Device complexityVSExtent of automation

Solution Approach 1:

The controller monitors the operational status and sanitizer needs of both the pool and spa systems, then automatically adjusts the current distribution from the single power source accordingly. This feedback mechanism ensures that the power source delivers current to the appropriate sanitizer generator based on real-time system conditions.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The control system automatically manages the current distribution without requiring manual intervention. The controller assesses which body of water needs sanitization and independently directs the power source to the appropriate generator, enabling the system to self-regulate and maintain proper sanitizer levels in both the pool and spa.

Inventive Principle:
Principle #25Self-service
