Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the magnet plate is made detachable and replaceable through carriers, then the ease of operation and maintenance is improved, but the device complexity increases due to additional components and replacement mechanisms
Solution Approach 1:
The magnet plate is divided into a separate replaceable component that can be independently handled via carriers, allowing the main deposition device to remain intact while the magnet plate is replaced through standardized carrier operations
Solution Approach 2:
Carriers are introduced as intermediary components that facilitate the transfer and replacement of magnet plates without requiring direct manual handling or complex disassembly of the deposition device, simplifying the replacement process
2Ease of repair
If the magnet plate is detachably connected to the driving mechanism, then the ease of repair and component replacement is improved, but the reliability may be affected by connection and disconnection operations
Solution Approach 1:
The magnet plate is pre-loaded onto carriers outside the deposition chamber, and the detachable connection interfaces are designed and prepared in advance, allowing for quick and reliable replacement without compromising the integrity of the deposition process
3Productivity
If carriers are used to transport and replace magnet plates, then the productivity is improved through efficient replacement, but the device complexity increases due to additional transport and handling mechanisms
Solution Approach 1:
The carriers are designed as multi-functional components that can transport magnet plates, position them precisely, and interface with the driving mechanism, consolidating multiple functions into a single standardized component that improves productivity without proportionally increasing complexity
