Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the carrier is transported in a horizontal position using a transport unit, then the ease of operation and loading is improved, but the deposition precision deteriorates
Solution Approach 1:
The carrier position changing device dynamically changes the carrier's orientation from horizontal to vertical. The rotating objects (first and second rotating objects) enable the carrier to transition between different positional states, allowing the system to adapt to different operational requirements - horizontal for easy loading and vertical for precise deposition
Solution Approach 2:
The device changes the spatial parameter (orientation angle) of the carrier from 0 degrees (horizontal) to 90 degrees (vertical). By controlling the rotation angle of the rotating objects, the system can precisely adjust the carrier's position to optimize both ease of operation and deposition precision
2Manufacturing precision
If the carrier position is changed from horizontal to vertical, then the deposition precision is improved, but the device complexity increases
Solution Approach 1:
The carrier position changing device is segmented into distinct functional components: driving objects for power transmission, first and second rotating objects for rotation, connecting portions for structural linkage, and support members for stability. This modular segmentation allows each component to perform its specific function efficiently while maintaining overall system manageability
Solution Approach 2:
The connecting portions act as intermediaries that link the driving objects to the rotating objects and support members. These connecting structures transmit motion and force while providing structural support, enabling the complex position change function through a series of simplified intermediate steps
3Manufacturing precision
If rotating objects and connecting portions are used to change carrier position, then the deposition precision is improved, but the device complexity increases
Solution Approach 1:
The first rotating object, second rotating object, connecting portions, and support members are merged into an integrated carrier position changing device. This combination allows the system to achieve complex carrier orientation changes through coordinated action of multiple components working together as a unified mechanism, improving deposition precision while managing complexity through functional integration
