Rackmount Conversion Rail for In-Place Blade Height Reconfiguration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rackmount chassis designs impose fixed size requirements on blades, making it impossible to reconfigure to accommodate blades of different heights without removing the entire chassis from the rack, leading to undesirable system downtime and labor expenses for upgrades.
Innovation Solution
Incorporating support plates that run the length of the chassis with removable support rails and elements that can be adjusted to accommodate blades of varying heights, allowing in-situ reconfiguration without removing the chassis from the rack.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional rackmount chassis with fixed center support is used, then structural stability is maintained, but the chassis cannot be reconfigured to accommodate blades of different heights without complete removal from the rack
Solution Approach 1:
The fixed center support is divided into multiple adjustable support elements that can be independently positioned at different heights. Each support element can be separately adjusted along the support plate, allowing the chassis to accommodate various blade heights while maintaining overall structural integrity.
Solution Approach 2:
The static center support structure is transformed into a dynamic, adjustable configuration. The support elements can be moved along the support plate and locked at different positions, enabling the chassis to adapt to different blade height requirements without complete reconfiguration or removal from the rack.
2Adaptability or versatility
If the entire chassis is removed from the rack for reconfiguration, then blade height compatibility is improved, but system downtime and labor expenses increase
Solution Approach 1:
The support elements are pre-configured with multiple adjustable positions along the support plate. This preliminary design allows operators to quickly adjust the support height to match the required blade height without needing to remove the entire chassis from the rack, significantly reducing reconfiguration time and system downtime.
Solution Approach 2:
The adjustable support elements enable dynamic reconfiguration of the chassis while it remains installed in the rack. Operators can modify the support height in-situ to accommodate different blade heights, eliminating the need for complete chassis removal and reinstallation, thereby minimizing system downtime and labor expenses.
3Ease of manufacture
If fixed support slots are used, then manufacturing simplicity is maintained, but reconfiguration flexibility is lost
Solution Approach 1:
The fixed support slots are segmented into multiple discrete positioning locations along the support plate. Each slot corresponds to a specific height position, allowing the support elements to be easily manufactured with pre-defined stopping points while still providing multiple reconfiguration options for accommodating different blade heights.
Solution Approach 2:
The support element design incorporates adjustable parameters, specifically the height position along the support plate. By providing multiple discrete height positions through the segmented slot design, the system maintains manufacturing simplicity while enabling reconfiguration flexibility to accommodate various blade height requirements.

AI summary
A rackmount chassis includes removable supports that provide interior support for blades having mounting edge-to-mounting edge dimensions that are less than the full chassis width. The removable supports are mounted on parallel support plates that span the full width of the chassis. Each removable support supports an edge of at least one blade installed into the rackmount chassis. The locations of the removable supports on the parallel support plates determine the blade form factors (mounting edge-to-mounting edge dimensions) that the rackmount chassis can accept. Because the removable supports can be individually removed/installed, the configuration of the resulting rackmount component can be changed without physically removing the rackmount component from the rack in which it is mounted.
