Aquarium Pump Stator Rotor Segmentation for Leakage Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aquarium designs face safety hazards due to electric leakage from submersible water pumps and aesthetic issues with external pump installations, which complicate pipe connections.
Innovation Solution
An aquarium design where the stator and rotor of the water pump are positioned such that the stator is outside the tank body and the rotor is inside, with the stator chamber encapsulated to prevent water contact and a power line channel hidden within the base, ensuring safe operation and a clean appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a submersible pump is adopted and installed in the tank, then water circulation function is achieved, but electric leakage safety hazard occurs and power line enters tank from upper opening influencing appearance
Solution Approach 1:
The water pump is divided into two separate chambers: a stator chamber located outside the tank body and a rotor chamber located inside the tank body. The stator containing electrical components is isolated from water through the tank wall, eliminating electric leakage hazards while maintaining water circulation function through the rotor impeller inside the tank.
Solution Approach 2:
The stator and electrical components are extracted from the tank interior and placed in a separate stator chamber outside the tank body. This extraction removes the electrical components from the water environment, eliminating safety hazards while the rotor inside the tank continues to provide water circulation.
2Reliability
If the water pump is installed outside the tank, then electrical components are not soaked in water, but pipe connection becomes complicated influencing appearance
Solution Approach 1:
The stator chamber and rotor chamber are merged through a communication passage that allows water to flow between the external stator chamber and internal rotor chamber. This integration eliminates the need for complex external piping while maintaining electrical component isolation from water.
Solution Approach 2:
The rotor chamber is nested within the tank body while the stator chamber is positioned outside, with the two chambers connected through a communication passage. This nested arrangement allows compact integration of pump components while maintaining safety isolation of electrical parts from water.
3Reliability
If stator chamber is arranged outside tank body, then electrical components are not soaked in water, but power line channel must be arranged to accommodate power line
Solution Approach 1:
The power line channel is merged with the base structure, integrating the power line routing into the existing base design. This integration accommodates the power line connection between the stator chamber and external power source without adding separate complex routing structures.

Function Achieved in This Case
This configuration prevents electric leakage and enhances the aesthetic appeal of the aquarium by eliminating the need for a power line to enter the tank, while maintaining efficient water circulation and filtration.
Implementation Method 1
a stator chamber configured to accommodate the stator, arranged at one side of the tank wall close to outside of the tank body and arranged at a position corresponding to a position of the rotor chamber so that the stator drives the rotor
