Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computing systems face challenges in efficiently connecting computing tiles between adjacent cabinets, particularly in high-performance computing applications, due to mechanical constraints on electrical connections and limited space within cabinets.
Innovation Solution
A blind connector system that utilizes a holder tube and an external assembly tool to connect and adjust blind connectors between computing tiles in adjacent cabinets, allowing for independent alignment and connection of each side of the blind connector, and incorporating a Y-pullback mechanism for increased clearance during system tray insertion and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a connector is used to connect computing tiles between adjacent cabinets, then electrical connections are established, but mechanical constraints limit the connection flexibility and signal integrity
Solution Approach 1:
The connector assembly is segmented into multiple independent adjustment mechanisms (X-adjustment, Y-adjustment, Z-adjustment) that can be controlled separately. This allows each degree of freedom to be optimized independently, reducing mechanical constraints while maintaining signal integrity for high-speed electrical connections between computing tiles.
Solution Approach 2:
The connector assembly incorporates dynamic adjustment capabilities through motorized or manually operable adjustment mechanisms that allow real-time modification of connector position and orientation. This dynamic adaptability enables the connector to compensate for manufacturing tolerances and thermal expansion, maintaining reliable electrical connections without rigid mechanical constraints.
2Ease of operation
If the connector is positioned within the cabinet for connection, then electrical connections are made, but limited space restricts access for alignment and adjustment
Solution Approach 1:
The adjustment mechanisms are nested within the connector assembly structure itself, with adjustment plates and mechanisms integrated into the connector housing. This nested configuration provides full adjustment functionality while minimizing the space required within the cabinet, allowing easy access for alignment without increasing overall cabinet volume.
Solution Approach 2:
The holder tube acts as an intermediary component that extends the adjustment mechanism's reach to the connector position. This allows operators to access and adjust the connector from a convenient location outside the tight cabinet space, maintaining ease of operation without requiring additional cabinet volume.
3Reliability
If the connector is fixed in position for stable connection, then electrical connections are secured, but clearance for system tray insertion and removal is reduced
Solution Approach 1:
The connector assembly incorporates a pullback mechanism that allows the connector to be dynamically repositioned to a retracted state. In this retracted position, the connector maintains its stable electrical connection while providing the necessary clearance for system tray insertion and removal. The connector can then be advanced to its operational position when connection is required.
Solution Approach 2:
The connector operates in periodic cycles between retracted and extended positions. During tray insertion/removal operations, the connector is in the retracted position providing clearance. When connection is needed, the connector advances to establish stable electrical contact. This periodic positioning resolves the conflict between connection stability and operational clearance.
