Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional methods are used to produce multi-layer plain bearings, then the connection between carrier body and bearing body can be achieved, but the manufacturing process becomes complex and expensive
Solution Approach 1:
The patent replaces traditional mechanical pressing systems with a magnetic field-based system. A coil generates a magnetic field that acts on the bearing body containing ferromagnetic particles, eliminating the need for complex mechanical pressing apparatus while achieving firm connection between the carrier body and bearing body.
Solution Approach 2:
The patent changes the physical state and distribution of ferromagnetic particles within the bearing body by applying a magnetic field. The magnetic field causes the particles to align and concentrate in specific regions, fundamentally altering the internal structure and connection properties of the bearing body without mechanical intervention.
2Ease of manufacture
If direct contact pressing is used to connect bearing body to carrier body, then connection can be formed, but the process requires complex mechanical systems and high cost
Solution Approach 1:
The patent substitutes mechanical pressing with electromagnetic interaction. The coil generates a magnetic field that penetrates the bearing body and interacts with ferromagnetic particles, creating strong internal forces that secure the connection without any mechanical contact or complex pressing mechanisms.
Solution Approach 2:
The magnetic field acts as an intermediary between the coil and the bearing body. Instead of direct mechanical contact, the magnetic field transmits force through the bearing body material, particularly through the ferromagnetic particles, to achieve secure connection to the carrier body.
3Strength
If bearing body is deformed to create connection, then firm bond is achieved, but traditional deformation methods require complex equipment
Solution Approach 1:
The patent replaces mechanical deformation equipment with an electromagnetic system. The magnetic field generated by the coil induces forces within the ferromagnetic particles of the bearing body, causing internal deformation and reconfiguration that creates strong connection without external mechanical deformation apparatus.
Solution Approach 2:
The magnetic field changes the spatial distribution and arrangement of ferromagnetic particles within the bearing body. This parameter change in particle configuration creates internal structural deformation that enhances connection strength, replacing the need for external mechanical deformation processes.
