Pump Motor Control Board for Multi-Protocol Remote Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pool and spa pump systems face limitations due to the variability in communication protocols used by different remote control systems, requiring a control system configured for a single protocol, which hinders compatibility and flexibility.
Innovation Solution
A control system is introduced that includes a first control board for communication with remote control systems and a second control board for motor operation, capable of interpreting and processing commands from various protocols, including RS485, Bluetooth, WiFi, and others, to universally control the pump motor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a control system implements comprehensive support for multiple unique communication protocols to ensure compatibility with various remote control systems, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent introduces an intermediary translation layer between the control system and remote control systems. The control system receives commands in a universal format, translates them into protocol-specific formats for different remote control systems (e.g., Intelli-Breeze, Aquatic Systems), and translates responses back to universal format. This mediator approach enables broad compatibility without implementing each protocol comprehensively within the control system itself.
Solution Approach 2:
The control system implements a universal command interface that can communicate with multiple types of remote control systems through a standardized protocol. Rather than embedding multiple protocol implementations, the system uses a universal communication framework that handles diverse protocols through translation and adaptation layers, making the control system itself simpler while maintaining broad compatibility.
2Adaptability or versatility
If a control system implements comprehensive support for multiple unique communication protocols, then adaptability is improved, but manufacturing complexity and recertification requirements increase
Solution Approach 1:
The patent divides the communication functionality into separate modular components. The control board handles universal command translation while the remote control system maintains its protocol-specific implementation. This segmentation allows control boards to be replaced and manufactured independently without requiring recertification of the entire system, as each component maintains its own protocol compatibility through the universal interface.
Solution Approach 2:
By introducing a universal command interface as an intermediary, the patent decouples the control board from protocol-specific implementations. This allows control boards to be manufactured and replaced without affecting protocol compatibility, which is maintained by the translation layer. Consequently, recertification requirements are minimized since the core control functionality remains unchanged.
3Adaptability or versatility
If remote control systems use unique communication protocols with varying formats and data rates, then customization for specific systems is improved, but communication reliability deteriorates due to integration complexity
Solution Approach 1:
The patent establishes a homogeneous universal command format that all communications pass through. Remote control systems send commands in their native protocols, which are translated into a standardized universal format for processing. This homogenization at the processing layer ensures consistent and reliable communication regardless of the source protocol variations, while still allowing system-specific optimizations to be maintained in the translation layer.

AI summary
A control system for controlling an electric motor in a pump system. The control system includes a communications interface configured to be electrically coupled with a remote control system and receive a command therefrom. The control system further includes a processing unit coupled to the communication interface and configured to receive the command from the communications interface, process the command to determine which communication protocol among a plurality of communication protocols to employ, and control the communications interface to transmit a response to the command using at least a portion of the communication protocol.
