Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual opening and closing of inputting and outputting trays is used, then device complexity is reduced, but ease of operation deteriorates due to user inconvenience
Solution Approach 1:
The linkage mechanism enables the trays to automatically open and close themselves through mechanical coupling. When one tray is moved, the linkage bars transmit the motion to the other tray, making the system self-operating without requiring manual intervention for both trays simultaneously.
Solution Approach 2:
The invention combines the opening and closing operations of two separate trays into a single coordinated action through the linkage mechanism. The linkage bars merge the independent movements of the inputting tray and outputting tray into a synchronized operation, improving ease of use.
2Ease of operation
If linkage mechanism is added to link inputting and outputting trays, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The linkage bars serve as intermediary elements that connect the inputting tray and outputting tray. These bars transmit and coordinate the motion between the two trays, enabling synchronized operation while maintaining a relatively simple structural design.
Solution Approach 2:
The linkage mechanism introduces dynamic coupling between the trays, allowing them to move in coordination rather than independently. The pivot connections and linkage bars create a dynamic system that automatically coordinates tray movements during operation.
3Productivity
If synchronized opening and closing of trays is achieved, then productivity is improved, but device complexity increases due to additional linkage components
Solution Approach 1:
The synchronized operation is achieved through self-service mechanics where the linkage bars automatically coordinate the tray movements without requiring external control systems. This mechanical self-coordination improves productivity by enabling faster, more efficient tray operations.
Solution Approach 2:
The linkage mechanism is pre-configured with pivot connections and bar linkages that are established during assembly. This preliminary structural arrangement ensures that synchronized operation occurs automatically during use, improving productivity without requiring complex real-time control.
