Solution Overview
Problem
There is a need for a system that can centrally control and automate various components of a swimming pool, including pumps, filters, valves, heaters, and lights, while allowing for programmed scheduling and monitoring of pool conditions, and providing alerts when parameters are exceeded, without requiring physical access to the pool equipment.
Innovation Solution
A customizable pool automation control system featuring a microprocessor controller, main PCB board, relays, sensors, and optional touchscreen interface, enabling wireless and remote access via Wi-Fi, Bluetooth, or Internet, with modular expansion cards for additional functionality such as salt water generator control, video cameras, and water level management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a centralized pool automation control system is implemented to control multiple pool components, then the ability to monitor and control pool equipment remotely is improved, but the device complexity increases due to integration of multiple control functions
Solution Approach 1:
The patent combines multiple control functions (pump control, valve control, heater control, chemical dosing) and monitoring capabilities (temperature sensors, flow sensors, water level sensors) into a single centralized controller unit. This merging of previously separate control systems into one integrated device enables remote monitoring and control while managing the complexity through unified architecture.
Solution Approach 2:
The controller is designed as a universal device capable of interfacing with various pool equipment types (pumps, filters, heaters, chemicals, lights) through standardized communication protocols. This multi-functionality allows a single device to perform diverse control tasks, improving ease of operation without proportionally increasing complexity.
2Adaptability or versatility
If modular expansion cards are added to provide additional control functionality, then the adaptability and versatility of the system are improved, but the device complexity increases
Solution Approach 1:
The control system is divided into modular functional blocks represented as expansion cards (e.g., pump control card, valve control card, heater control card). Each card handles a specific control function, allowing the system to be customized by adding only the necessary modules. This segmentation enables versatility while managing complexity through standardized interfaces between modules.
Solution Approach 2:
The system architecture allows dynamic configuration where expansion cards can be added or removed based on specific pool requirements. The controller adapts its operation to accommodate different combinations of expansion cards, providing adaptability without requiring a complete system redesign for each configuration.
3Ease of operation
If wireless access capabilities are integrated for remote monitoring, then the ease of operation is improved, but the use of energy increases
Solution Approach 1:
The wireless communication system is designed to transmit data periodically rather than continuously. The controller sends status updates at scheduled intervals and enters low-power states between transmissions. This periodic communication maintains remote monitoring capability while significantly reducing the energy consumption compared to continuous wireless data streaming.
