Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional pumps with contacting rotor and stator are used, then pumping function is achieved, but wear and tear occurs leading to reduced reliability
Solution Approach 1:
The patent extracts and eliminates the harmful contact interaction between rotor and stator by introducing a magnetic field coupling mechanism. The rotor and stator are separated by a gap, with magnetic forces transmitted through the fluid medium, eliminating mechanical wear while maintaining pumping function.
Solution Approach 2:
The patent replaces direct mechanical contact between rotor and stator with magnetic field interaction. The rotor generates a magnetic field that interacts with the stator through the fluid, enabling force transmission without physical contact, thus eliminating wear and extending service life.
2Reliability
If lubricant is applied to reduce friction, then wear is reduced, but lubricant contamination occurs in the cooling system
Solution Approach 1:
The patent replaces mechanical contact requiring lubrication with magnetic field interaction. The magnetic coupling mechanism transmits forces between rotor and stator without physical contact, eliminating the need for lubricants and preventing contamination of the cooling medium.
Solution Approach 2:
The patent introduces a magnetic field as an intermediary between rotor and stator, allowing force transmission through the fluid medium without direct contact. This intermediary mechanism eliminates the need for lubricants while maintaining efficient power transmission.
3Productivity
If rotor and stator contact to transfer force, then pumping efficiency is maintained, but friction causes wear and motor burnout
Solution Approach 1:
The patent replaces direct mechanical force transfer with magnetic field interaction. The rotor's magnetic field couples with the stator through the fluid, enabling efficient force transmission without friction, thus maintaining pumping efficiency while preventing motor burnout from wear debris.
