Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In swimming pool filtration installations, users face difficulties in manually selecting the correct operating position for a multiport valve and adjusting the hydraulic pump speed, leading to inefficiencies, energy wastage, and potential system failures due to inappropriate settings.
Innovation Solution
A control and operating system that includes detection means to determine the angular position of the multiport valve and a wireless communication system to automatically control the pump speed, ensuring the pump operates at the appropriate speed for the selected operation, using a magnetometer and/or accelerometer for position detection and a wireless emitter/receiver for communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the user manually selects the valve position and pump speed separately, then the system can operate in different modes, but the user must perform multiple manual adjustments which increases operation time and risk of mismatch between valve position and pump speed
Solution Approach 1:
The patent combines the valve position selection and pump speed control into a single integrated system. The control unit receives the valve position signal and automatically determines the corresponding pump speed, merging two separate manual adjustments into one coordinated operation. This eliminates the need for users to independently adjust both valve position and pump speed, reducing operational complexity while maintaining multiple operational modes.
Solution Approach 2:
The system performs self-adjustment by automatically setting the pump speed based on the detected valve position. Once the user selects a valve position, the control unit autonomously determines and adjusts the corresponding pump speed without requiring additional user input. This self-service mechanism eliminates manual pump speed adjustment and prevents mismatches between valve position and pump speed settings.
2Speed
If the pump speed is not adjusted promptly after valve position change, then the system responds slowly to operational changes, but the pump continues to operate at inappropriate speed causing water hammers and energy wastage
Solution Approach 1:
The patent implements a feedback mechanism where the control unit continuously monitors the valve position through the detection means and automatically adjusts the pump speed in response to position changes. This closed-loop feedback system ensures the pump speed is promptly and appropriately adjusted whenever the valve position changes, preventing water hammers and energy wastage while maintaining fast system response and operational reliability.
3Adaptability or versatility
If the user manually adjusts pump speed from pre-established values, then the pump can operate at different speeds, but the user may select an inappropriate speed for the chosen valve position leading to system failures
Solution Approach 1:
The system automatically determines and sets the appropriate pump speed based on the detected valve position, eliminating the need for users to manually select from pre-established speed values. The control unit autonomously matches the pump speed to the operational mode indicated by the valve position, ensuring correct operation while maintaining the ability to operate at different speeds as needed. This prevents user errors and system failures caused by inappropriate speed selections.

AI summary
A control and operating system for a swimming pool filtration installation, comprising a hydraulic pump; a control device for controlling the speed of the pump; and a multiport valve with rotational control means for operating the stem of the valve according to which the valve can adopt at least two operating positions. The valve is provided with detection means for detecting at least the angular position of its stem with respect to a reference plane, preferably a horizontal plane, and with an emitter for emitting the position or information relating to said position. The control device is provided with a receiver for receiving the information emitted by the emitter of the valve, capable of generating a command on the control device for controlling the speed of the pump to operate the pump in a specific operating cycle and/or at a specific rotational speed.
