Split Pump Motor Control Boards for Wireless Access and Easy Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pool and spa pump systems lack efficient wireless control mechanisms that allow for user interaction and system-level command translation without requiring direct physical access to the pump motor, and they often require recertification upon component replacement.
Innovation Solution
A control system is implemented with a first control board outside the pump motor housing for wireless communication and user input processing, and a second control board inside the housing for motor control, allowing separate replacement and maintenance of the first board without affecting certification of the second board.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the control board is integrated inside the pump motor housing, then the system structure is compact and simple, but the control board cannot be easily replaced and requires recertification of the entire motor assembly
Solution Approach 1:
The control system is divided into two separate portions: a first control board portion disposed outside the motor housing and a second control board portion disposed inside the motor housing. This segmentation allows the external control board to be easily replaced without affecting the internal control board or requiring motor recertification, while the internal control board remains integrated for compact operation.
2Ease of operation
If the control board is accessible outside the housing, then user interaction and maintenance are easier, but the control system requires more complex wiring and communication interfaces
Solution Approach 1:
A communication interface serves as an intermediary between the external first control board portion and the internal second control board portion. This intermediary enables wireless or wired communication between the two separated control boards, allowing user interaction and control while managing the complexity of the communication protocol and data transmission.
3Ease of operation
If wireless communication interface is added for remote control, then user convenience is improved, but the control system becomes more complex and requires additional components
Solution Approach 1:
The wireless communication interface is extracted and integrated into the external first control board portion, separating it from the motor housing and internal control board. This extraction allows the wireless functionality to be added without modifying the certified motor assembly, as the wireless interface resides on the removable external control board.
4Reliability
If the control board is protected inside the housing, then the control system is more secure and protected from environmental factors, but access for control and debugging is limited
Solution Approach 1:
The control system is segmented into external and internal portions, placing the user-accessible first control board outside the housing for easy operation and debugging, while the critical second control board remains protected inside the motor housing. This segmentation balances protection requirements with operational accessibility.

AI summary
A control system for a pump motor includes a first portion disposed outside a housing of the pump motor. The first portion may include a wireless communication interface and a processor. In some embodiments, the processor of the first portion is configured to control the wireless communication interface to receive a user input from a user device, and generate a control signal in response to receiving the user input. The control system also includes a second portion physically separate from the first portion and communicatively coupled to the first portion. The second portion may include a processor configured to receive the control signal from the first portion, and control the pump motor in response to receiving the control signal.
