Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a simple up-and-down superposition of magnetic levitator and lifting mechanism is used, then automatic levitation is achieved, but the base height is remarkably increased
Solution Approach 1:
The lifting mechanism is nested within the base structure rather than being externally superimposed. The threaded stud is embedded in the base, and the displaceable support moves along this internal threaded path, allowing the lifting mechanism to be contained within the base's footprint and minimizing height increase.
Solution Approach 2:
The lifting mechanism transitions from vertical superposition to a combination of vertical and radial integration. The displaceable support not only moves vertically but also rotates radially around the threaded stud, utilizing multiple dimensions to achieve compact integration while maintaining automatic levitation functionality.
2Ease of operation
If lifting mechanism protrudes out of base surface, then levitation function is achieved, but base integrity is compromised
Solution Approach 1:
The problematic protruding lifting mechanism is extracted and replaced with an internal threaded stud embedded in the base. The displaceable support remains contained within or flush with the base surface, eliminating visual protrusions while maintaining the levitation function through the threaded engagement mechanism.
Solution Approach 2:
The lifting mechanism components are merged with the base structure. The threaded stud becomes an integral part of the base, and the displaceable support integrates with the magnetic levitator assembly, creating a unified structure that maintains base integrity while enabling levitation.
3Extent of automation
If threaded stud and displaceable support mechanism is used, then automatic levitation and rotation are achieved, but device complexity increases
Solution Approach 1:
The threaded stud and displaceable support mechanism serve multiple functions simultaneously: providing vertical lifting through threaded engagement, enabling rotation through radial movement, and maintaining magnetic alignment. This multi-functionality reduces the need for separate mechanisms, thereby limiting complexity increase despite enhanced automation.
