Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the stator housing protrudes into the water chamber to enable the impeller to drive fluid flow, then the water pump can drive the fluid, but the volume of the water chamber is reduced and the overall thickness increases
Solution Approach 1:
The patent transitions from a radial tangency arrangement to an axial tangency arrangement where the stator and rotor are stacked axially rather than radially. This dimensional change allows the magnetic induction coil to be positioned above the impeller assembly, eliminating the need for the stator housing to protrude into the water chamber, thereby preserving water chamber volume while maintaining fluid driving capability
Solution Approach 2:
The patent inverts the traditional radial arrangement by implementing an axial arrangement where the magnetic field is generated above the impeller rather than radially around it. This inversion allows the water chamber to maintain its full volume without accommodation for protruding stator components
2Device complexity
If the water pump and water chamber are integrated in existing designs, then the structure is compact, but the stator housing protrudes into the water chamber reducing its effective volume
Solution Approach 1:
The patent resolves the volume reduction issue by changing the spatial arrangement from radial to axial stacking. The stator and rotor are positioned in the axial direction above the impeller, allowing the water chamber to extend fully in the radial direction without obstruction, thus maintaining both integration and full water chamber volume
Solution Approach 2:
The patent segments the drive device into distinct axial layers: the magnetic induction coil (stator) is positioned in the upper layer, the rotor and impeller assembly in the lower layer, and the water chamber occupies the radial space without interference from protruding components. This segmentation allows each component to occupy its optimal space
3Volume of stationary object
If the water pump and water chamber are separated, then the water chamber volume is maintained, but the structural integrity and aesthetics are poor
Solution Approach 1:
The patent merges the water pump and water chamber into a single integrated housing structure where the stator and rotor are axially stacked above the impeller assembly within the same housing. This integration maintains structural integrity and aesthetics while the axial arrangement ensures the water chamber volume is not compromised by protruding components
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution achieves a compact, aesthetically pleasing design with improved reliability, reduced production costs, and extended service life by minimizing concave-convex structures and using axial flux motors for efficient heat dissipation.
Implementation Method 1
a magnetic induction coil of a stator needs to be tangent to a device (that is, the stator is a magnetic induction coil, and the rotor is arranged on the outer circumference of the stator, forming a radial tangency)
Implementation Method 2
when the impeller rotates, the impeller is arranged to drive fluid to flow from the fluid inlet, through the water chamber, and into the fluid outlet
