Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional screws are used to couple two plates, then stable coupling is achieved, but assembly speed is slow
Solution Approach 1:
The patent replaces the conventional mechanical screw-fastening system with an electromagnetic fastening system. The electromagnetic fastener uses magnetic attraction forces generated by electromagnetic coils to couple two plates, eliminating the need for mechanical threading and manual screw operation. This substitution enables automated, rapid assembly while maintaining secure coupling through controlled magnetic forces.
Solution Approach 2:
The patent utilizes changes in electromagnetic parameters (current magnitude, magnetic field strength) to control the fastening force. By varying the electrical current supplied to the electromagnetic coils, the magnetic attraction force can be precisely controlled to achieve both rapid engagement and secure coupling, resolving the contradiction between assembly speed and coupling stability.
2Reliability
If conventional screws are used to fix plates, then stable coupling is achieved, but quick assembly is not possible
Solution Approach 1:
The electromagnetic fastening system replaces time-consuming mechanical screw operations with rapid electromagnetic engagement. The electromagnetic coils can be energized instantaneously to create magnetic attraction, enabling quick assembly without the need for manual threading, tightening, or tool operation associated with conventional screws.
Solution Approach 2:
The electromagnetic fastener components are pre-positioned and aligned on both plates before engagement. When electrical power is applied, the magnetic attraction force is immediately activated to secure the coupling, eliminating the sequential steps required for manual screw fastening and significantly reducing assembly time.
