Centrifugal Pool Pump with Dual Outlet Ports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pumps for fluid circulation systems in swimming pools and spas are not easily adaptable to various configurations, requiring significant disassembly and labor to align outlets with return lines, which are often positioned horizontally, vertically, or at intermediate angles.
Innovation Solution
A centrifugal pump assembly with dual outlet ports oriented vertically and horizontally, along with a cap system that allows users to select the outlet direction without manual disassembly, ensuring the pump can be easily configured to suit different system orientations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a pump has a single outlet that needs to be repositioned to adapt to different return line configurations, then the pump can be adapted to various system orientations, but substantial disassembly and manual handling are required
Solution Approach 1:
The outlet is divided into multiple separate outlet ports (first outlet port and second outlet port) positioned at different orientations on the pump housing. This segmentation allows the system to provide multiple outlet directions simultaneously without requiring disassembly or repositioning operations.
2Adaptability or versatility
If a pump has multiple outlet ports, then the pump can adapt to different system configurations without disassembly, but the device complexity increases
Solution Approach 1:
The pump housing is designed with multiple outlet ports that can serve different functional requirements. The first outlet port accommodates vertically positioned return lines while the second outlet port accommodates horizontally positioned return lines, making the single pump unit universally adaptable to various system configurations.
Solution Approach 2:
Multiple outlet ports are integrated into a single pump housing structure, combining what would traditionally require multiple separate pump units into one unified device. This merging provides multiple outlet directions without requiring separate pumps for different configurations.
3Adaptability or versatility
If a contractor carries two sets of pumps with different outlet positions, then the correct pump can be selected for any configuration, but the quantity of equipment and inventory requirements increase
Solution Approach 1:
A single pump unit with multiple outlet ports replaces the need to maintain multiple separate pump units. The first outlet port serves vertically positioned return lines and the second outlet port serves horizontally positioned return lines, making one pump unit universally applicable to configurations that previously required two different pump units.
