Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If frequency modulation motors are used for speed regulation, then speed control is achieved, but complete synchronization of roller rotating speeds cannot be ensured
Solution Approach 1:
The patent replaces frequency modulation motors with servo motors that have higher precision control capabilities. The servo motor system provides closed-loop feedback control, ensuring that all pressing rollers rotate at precisely synchronized speeds, thereby resolving the synchronization precision issue while maintaining speed control.
Solution Approach 2:
The patent introduces a synchronous control system with feedback mechanisms that monitor the rotating speeds of multiple pressing rollers and adjust them to maintain complete synchronization. This feedback control ensures that all rollers operate at the same speed throughout the molding process.
2Speed
If rolling bearings are used to support pressing rollers, then rotation is facilitated, but internal crushing and deformation of bearings occur under high molding pressure
Solution Approach 1:
The patent changes the material parameter of the bearing from standard rolling bearing steel to copper alloy material. This material substitution provides higher softness and conformability, allowing the bearing to deform elastically under high pressure without internal crushing, thereby maintaining reliability while still facilitating roller rotation.
Solution Approach 2:
The patent employs composite bearing structures that combine copper alloy materials with optimized geometric designs. These composite bearings integrate the advantages of material softness for pressure distribution with structural integrity for rotational support, eliminating the failure mode of internal crushing while maintaining rotational function.
