Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If faulty memories are directly replaced, then server stability is maintained, but memory utilization rate decreases
Solution Approach 1:
The patent applies preliminary action by detecting and identifying faulty memories before they cause server breakdowns. The system continuously monitors memory health parameters and detects potential failures early, allowing for proactive repair operations that prevent complete memory failure while maximizing memory utilization.
Solution Approach 2:
The patent implements discarding and recovering by repairing faulty memory modules rather than immediately replacing them. The repair process recovers usable functionality from failed memories through bit-level correction and redundancy activation, extending their service life and improving overall memory utilization rates.
2Measurement precision
If comprehensive memory detection is performed, then detection accuracy improves, but detection time increases
Solution Approach 1:
The patent applies local quality by implementing selective detection strategies tailored to different memory modules based on their individual health parameters. Rather than uniformly detecting all memories, the system identifies at-risk modules through continuous monitoring and applies comprehensive detection only to those needing it, optimizing the balance between accuracy and time.
Solution Approach 2:
The patent implements dynamics by adapting detection intensity based on real-time memory health status. The system dynamically adjusts detection strategies from basic monitoring to comprehensive testing based on detected anomalies, memory age, and failure history, allowing flexible optimization of detection accuracy versus time consumption.
