Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional control systems use direct physical electrical connection to devices, then control reliability is improved, but system scalability and remote access capability deteriorate

Engineering Contradiction:
Improvecontrol reliabilityVSAvoidsystem scalability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent introduces a control system load center as an intermediary device that receives commands from remote devices via electronic communication networks and translates them into physical electrical signals for pool/spa devices. This mediator enables remote control without direct physical connections between user devices and controlled devices, resolving the contradiction between control reliability and system scalability

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If conventional control systems require physical presence for operation, then control precision is improved, but user convenience and remote monitoring capability deteriorate

Engineering Contradiction:
Improveuser convenienceVSAvoidsystem status information
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The patent implements feedback mechanisms where sensors continuously monitor pool and spa device status, and this information is transmitted through the control system load center to remote devices. Users receive real-time status updates and can monitor system conditions remotely, eliminating information loss while improving ease of operation through remote access

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If conventional control systems use auxiliary circuits or relay outputs for device control, then control flexibility is improved, but device complexity and installation difficulty increase

Engineering Contradiction:
Improvecontrol flexibilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent creates a universal control system load center that can control multiple different types of pool and spa devices through a standardized interface. The system uses feature circuits with assignable logic functions that can be configured through software to control various devices without requiring different hardware configurations, reducing system complexity while maintaining control flexibility

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

AI summary

Systems and methods are provided for the control of pool or spa device circuits. A control system load center may control pool or spa device circuits in response to command data received from local or remote client devices. Activating a feature circuit may involve performing an associated logic function. Multiple feature circuits may be assigned to a feature circuit group which, when activated, may activate all feature circuits assigned to the feature group.
