Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If servers of varying depths are installed in a rack assembly, then the system can accommodate different server sizes and configurations, but tolerance loops and alignment issues arise that compromise installation precision and system reliability
Solution Approach 1:
The aggregate rail system is segmented into multiple depth positions, with each rail capable of being positioned at different depths within the rack assembly. This segmentation allows servers of varying depths to be installed at appropriate positions while maintaining proper alignment through the modular rail structure.
Solution Approach 2:
The aggregate rail system enables parameter changes by allowing the rails themselves to be positioned at different depths. This changes the fundamental parameter of rail position rather than trying to adapt fixed rails to different server depths, thereby eliminating tolerance loops while maintaining alignment precision.
2Ease of operation
If traditional power distribution systems are used with servers of varying depths, then installation is simplified, but power delivery efficiency and system performance deteriorate due to tolerance loops
Solution Approach 1:
The aggregate rail system introduces dynamics by making the rail positions adjustable rather than fixed. This allows the system to adapt to different server depths while maintaining optimal power delivery alignment, thereby improving both installation ease and power delivery efficiency simultaneously.
3Manufacturing precision
If fixed-depth rails are used in the rack assembly, then alignment is maintained, but the system cannot accommodate servers of different depths, reducing versatility
Solution Approach 1:
The rail system is segmented into multiple adjustable depth positions, allowing each rail to be independently positioned. This segmentation enables the system to maintain alignment precision at each position while providing versatility to accommodate servers of different depths by selecting the appropriate rail position.
