Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pool and spa pump motor energy consumption scheduling is complex and inconvenient, particularly when using sophisticated electronic controllers that require separate communicating devices for communication with energy provider control devices, leading to increased costs and labor due to frequent updates and replacements.
Innovation Solution
A system and method for managing commands for a pump electric motor that can receive and send signals using multiple protocols, allowing selection based on a predetermined priority structure, including message structure, checksum, data length, and baud rate, enabling communication with both user and utility control devices through a single motor controller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single motor controller is used to communicate with multiple protocols from different input sources, then device complexity is reduced and adaptability is improved, but the controller must handle multiple communication protocols simultaneously
Solution Approach 1:
The motor controller is designed to perform multiple communication functions by supporting multiple protocols (first protocol from first input source, second protocol from second input source) within a single device. This universal design allows the controller to interface with different energy provider control devices and user interfaces without requiring separate dedicated controllers for each protocol type.
Solution Approach 2:
The controller acts as an intermediary that receives commands in different protocol formats from various input sources and translates them into unified internal commands for the motor. It manages protocol conversion and coordination, allowing multiple external communication interfaces to work together through a single integrated control unit.
2Reliability
If separate communicating devices are used for each protocol, then communication reliability is maintained, but device complexity increases and cost increases
Solution Approach 1:
The patent combines multiple separate communicating devices into a single integrated motor controller that handles all protocol communications. Instead of having separate dedicated controllers for energy provider communication and user interface communication, the system merges these functions into one unified device that maintains reliable communication through multiple protocols.
Solution Approach 2:
The single motor controller is designed with universal capability to handle multiple communication protocols simultaneously, replacing the need for multiple specialized devices. This multi-functional approach maintains communication reliability while reducing the overall number of components in the system.
3Productivity
If multiple separate communicating devices are used, then protocol-specific communication is optimized, but labor for updates and replacements increases
Solution Approach 1:
The system merges multiple communication functions into a single controller, so that updates and protocol changes can be applied to one device rather than requiring separate updates to multiple independent devices. This reduces maintenance time and labor while preserving the communication efficiency benefits of protocol optimization.
Solution Approach 2:
The universal motor controller handles all protocol communications through a single integrated platform, allowing maintenance personnel to update and replace one device rather than multiple separate devices. This reduces the time and labor required for maintenance while maintaining the productivity benefits of efficient protocol-specific communication.

AI summary
According to an embodiment of the invention, a system for managing commands for a pump electric motor for powering a pump for use in a pool and/or a spa is provided. The system includes a user interface for receiving user commands from a user and a pump motor controller for controlling the pump electric motor. The user interface and/or the pump motor controller is adapted to receive first protocol commands utilizing a first protocol from a first input source and adapted to send first input source signals corresponding to the first protocol commands to a portion of the pump motor controller. The user interface and/or the pump motor controller is further adapted to receive second protocol commands utilizing a second protocol from a second input source and adapted to send second input source signals corresponding to the second protocol commands to a portion of the pump motor controller.
