Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the rotating plates are made rigid to maintain structural strength, then the plates can withstand axial loads, but the plates become prone to damage when subjected to excessive loads during the separation process
Solution Approach 1:
The rotating plates are designed with elastic deformability, changing the mechanical parameter from rigid to flexible. This allows the plates to deform under axial loads and return to their original shape, preventing permanent damage while maintaining structural integrity during the separation process
Solution Approach 2:
The rotating plates are configured to periodically change their projection state during rotation, transitioning between projected and non-projected states. This dynamic behavior allows the plates to adapt to varying loads, reducing the risk of damage while maintaining separation efficiency
2Reliability
If the rotating plates are made elastically deformable to prevent damage, then the plates can withstand axial loads without damage, but the separation efficiency may be reduced due to plate deformation
Solution Approach 1:
The rotating plates periodically transition between projected and non-projected states during rotation. This periodic action creates optimal conditions for liquid separation at specific moments while allowing elastic deformation at other moments, thereby maintaining both separation efficiency and damage resistance
Solution Approach 2:
The plates dynamically adjust their position and projection state during rotation, optimizing the separation action at critical moments while accommodating elastic deformation when less critical, thus balancing productivity and reliability
3Productivity
If the rotating plates are projected upward continuously to maximize liquid separation, then separation efficiency is improved, but axial loads increase causing plate damage
Solution Approach 1:
The rotating plates are configured to periodically repeat the state of being projected upward and the state of being not projected upward during rotation. This periodic projection reduces continuous axial loading while maintaining effective separation at critical moments, resolving the contradiction between productivity and force
Solution Approach 2:
By periodically reducing the projection state, the system preemptively reduces axial loads before they can accumulate to damaging levels, while still maintaining separation efficiency through strategic projection phases
