Water Pump Adjustable Discharge Direction via Rotatable Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water pumps have a fixed and unadjustable water discharge direction, which limits their usability and convenience.
Innovation Solution
A water pump design with a rotatable pump cover that allows the water inlet and outlet to be positioned at adjustable angles, featuring a handle seat with suckers for stability and ease of use, and a detachable filter cover and water discharge connector for flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the water outlet direction is fixed in the pump shell, then the pump structure is simple and stable, but the water discharge direction cannot be adjusted according to use needs
Solution Approach 1:
The pump cover is made rotatable relative to the pump body through a rotation mechanism, transforming the fixed water outlet direction into an adjustable one. The pump cover can rotate within a specified angle range (e.g., 0-180 degrees) while maintaining sealing through dynamic sealing elements, enabling the water discharge direction to be dynamically adjusted according to different use requirements without significantly increasing structural complexity.
2Adaptability or versatility
If the pump cover is made rotatable to adjust water discharge direction, then the water discharge direction becomes adjustable, but the sealing between pump body and pump cover becomes more difficult to maintain
Solution Approach 1:
A sealing ring is introduced as an intermediary element between the pump body and pump cover to maintain sealing during rotation. The sealing ring can be made of flexible materials that conform to the rotating interface, or a sliding seal mechanism that maintains continuous contact and sealing effectiveness throughout the rotation range, thus preserving sealing reliability while enabling directional adjustment.
3Adaptability or versatility
If the water inlet and outlet are moved to the pump cover, then the water discharge direction can be adjusted, but the pump shell structure becomes more complex
Solution Approach 1:
The water inlet and outlet connections are integrated into the pump cover, which itself becomes the adjustable component. By combining the function of the outlet connection with the rotation mechanism, the design avoids adding separate adjustment mechanisms while maintaining structural simplicity. The pump cover serves dual purposes: as a structural enclosure and as the adjustable element that controls water discharge direction.
