Solution Overview

Problem

Existing chlorinator systems for pools and spas lack on-board electronic circuitry and security mechanisms, leading to issues with incompatible and unsafe replacement cartridges, which can compromise safety and create economic impacts due to the market for counterfeit cartridges.

Innovation Solution

A system with a controller that communicates with a processor in the replaceable chlorinator cartridge, storing operational parameters and ensuring only compatible cartridges are used, including authentication and remote diagnostic capabilities to manage cartridge life and operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If standard connector systems are used for replaceable chlorinator cartridges, then ease of manufacture and installation is improved, but safety and compatibility are worsened due to knock-off cartridges

Engineering Contradiction:
Improveease of manufactureVSAvoidsafety
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent introduces an authentication system as an intermediary between the chlorinator cartridge and the chlorinator system. The cartridge includes a processor and memory that store authentication data, which must be verified by the chlorinator before operation is permitted. This intermediary authentication mechanism allows standard connectors to remain in use while preventing unauthorized cartridges from operating, thus maintaining ease of manufacture while improving safety.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If replaceable cell cartridges are used, then maintenance and replacement flexibility is improved, but system control and monitoring capabilities are worsened due to lack of on-board electronics

Engineering Contradiction:
Improvereplacement flexibilityVSAvoidoperational information
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The patent implements self-service capabilities by equipping the replaceable cartridge with its own processor and memory. The cartridge autonomously stores operational parameters, authentication data, and diagnostic information in its onboard memory, eliminating the need for external monitoring systems. This allows the cartridge to maintain and report its own status, preserving replacement flexibility while enabling comprehensive system control and monitoring.

Inventive Principle:
Principle #25Self-service

3Reliability

If authentication mechanisms are added to chlorinator cartridges, then safety and compatibility are improved, but device complexity increases

Engineering Contradiction:
ImprovesafetyVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the authentication functionality into a separate, self-contained module within the replaceable cartridge. The processor and memory dedicated to authentication are integrated into the cartridge itself, separating this complex function from the main chlorinator system. This extraction allows the authentication mechanism to be implemented without significantly increasing the overall system complexity, as the authentication subsystem is modular and contained within the easily replaceable cartridge.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

A method for remotely diagnosing errors associated with chlorinators for pools and spas is provided. The method comprises the steps of: - displaying at a computer system (208) a graphical user interface (210) replicating at least one control panel of a piece of pool or spa equipment (216); - allowing a user to replicate a control panel condition associated with the piece of pool or spa equipment using the graphical user interface (210); - processing the replicated control panel condition using a diagnostic software engine (204) to formulate a solution to the error or the malfunction; and - conveying the solution to the error or the malfunction to the user using the computer system (208).
