Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual or automated hand mounting is used to insert memory modules into sockets, then the mounting test can be conducted, but it takes a considerable amount of time
Solution Approach 1:
The system divides the mounting task into multiple parallel operations by providing multiple testers that can simultaneously test multiple memory modules. Each tester independently inserts modules into sockets and performs electrical tests, transforming a sequential process into a parallel one that dramatically reduces total test time while maintaining reliability.
Solution Approach 2:
The system enables continuous testing operation where multiple memory modules are tested simultaneously across multiple testers without interruption. The automated mechanism ensures uninterrupted insertion and testing cycles, eliminating idle time between operations and maintaining continuous productive action throughout the testing process.
2Productivity
If automated mounting is used to increase speed, then mounting time is reduced, but dislocation or damage may occur during the mounting process
Solution Approach 1:
The system performs preliminary positioning actions by accurately locating socket positions and orientations before the actual mounting operation. The tester is pre-configured with precise coordinates and angular orientations, ensuring that the automated mounting mechanism inserts modules correctly aligned, preventing dislocation and damage while maintaining high speed.
Solution Approach 2:
The system incorporates feedback mechanisms that monitor the mounting process in real-time and adjust positioning accordingly. Sensors detect the actual position and orientation of sockets, providing feedback to the control system which then corrects any deviations, ensuring accurate module insertion even during high-speed automated operation.
3Productivity
If automated mounting is implemented without teaching, then productivity increases, but dislocation or damage occurs when sockets and modules are not properly aligned
Solution Approach 1:
The system performs preliminary detection and adjustment of socket positions and orientations before automated mounting. By pre-identifying accurate socket locations and calculating required angular orientations, the system eliminates misalignment issues that would cause dislocation or damage, enabling high-speed automated testing without teaching while maintaining reliability.
4Measurement precision
If multiple memory modules are tested sequentially one by one, then individual performance can be evaluated, but the testing process becomes time-consuming
Solution Approach 1:
The system segments the testing workload by distributing multiple memory modules across multiple parallel testers. Each tester handles specific modules independently, allowing simultaneous evaluation of multiple modules rather than sequential testing. This segmentation maintains individual module evaluation precision while dramatically reducing total testing time through parallel processing.
Solution Approach 2:
The system merges multiple testing operations into a single integrated process where multiple testers work simultaneously on different modules. By combining parallel testing operations under a unified system architecture, the system achieves both comprehensive individual evaluation and efficient time utilization, eliminating the trade-off between precision and speed.
