Server Module Recognition Units for Accurate Joint Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional server devices incorrectly identify server modules due to misconnection of cables, leading to the wrong modules being replaced during repair, as they rely solely on joint positioning information without verifying the correct connection of cables.
Innovation Solution
Incorporating recognition units within each server module that generate and transmit recognition signals to the substrate, allowing the substrate to confirm correct module positioning by comparing these signals, thereby preventing incorrect module replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the substrate defines server module positions solely according to joint information, then the system structure is simple, but the positioning accuracy deteriorates leading to wrong module identification
Solution Approach 1:
The patent introduces recognition units as intermediary components between server modules and the substrate. Each recognition unit contains unique identification information that mediates the connection verification process, enabling the substrate to accurately identify which server module is connected to which joint through the transmitted recognition signals, thus resolving the positioning accuracy issue without overcomplicating the overall system architecture
Solution Approach 2:
The patent implements a feedback mechanism where recognition units transmit recognition signals back to the substrate to confirm correct connection. This feedback loop allows the substrate to verify whether server modules are properly connected to their designated joints by comparing the received recognition signals with expected values, thereby improving positioning accuracy through information feedback
2Reliability
If cable misconnection is not detected, then the ease of operation is maintained, but the reliability deteriorates causing wrong module replacement
Solution Approach 1:
The recognition units provide automatic feedback to the substrate about connection status through transmitted signals. This enables the system to automatically detect cable misconnections and identify the correct server modules, improving reliability without significantly impacting ease of operation as the verification process occurs automatically during system initialization or module connection
Solution Approach 2:
The system performs self-verification of connections through the recognition units and substrate interaction. The server modules themselves participate in the verification process by transmitting their identification information, enabling the system to self-diagnose connection status and identify correct modules for replacement, thereby improving reliability while maintaining operational simplicity
