Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If fixed fluid manifold configurations are used in racks, then manufacturing and installation are simplified, but interoperability between servers and racks with different fluid distribution architectures is reduced

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidinteroperability
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The rack side fluid manifold incorporates adjustable plates that can be positioned at multiple locations to accommodate different server connector positions. This dynamic adjustability allows the same rack design to work with various server fluid distribution architectures, resolving the contradiction between manufacturing simplicity and interoperability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system allows changing the position parameter of fluid connectors on the rack side manifold through adjustable plates. By modifying the connector position parameter to match different server configurations, the system maintains manufacturing simplicity while achieving broad interoperability across diverse server designs.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If customized connection designs are created for fixed server types, then connection reliability is improved, but cost increases and device complexity increases

Engineering Contradiction:
Improveconnection reliabilityVSAvoiddesign complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The rack side fluid manifold is designed as a universal interface that can connect to multiple server types with different fluid distribution architectures. The adjustable plates enable a single manifold design to serve multiple functions and accommodate various server configurations, reducing design complexity while maintaining connection reliability through proper alignment.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If blind-mating connectors are used for fluid connections, then ease of operation is improved, but reliability decreases due to potential leaks at the mating juncture

Engineering Contradiction:
Improveconnection easeVSAvoidleak prevention
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The adjustable plates are pre-positioned and spring structures are pre-loaded to apply inward force on connectors before the actual blind-mating connection occurs. This preliminary action ensures proper alignment and secure engagement of the blind-mating connectors, maintaining ease of operation while preventing leaks through pre-established proper connection geometry.

Inventive Principle:
Principle #10Preliminary action

AI summary

Disclosed are designs to facilitate blind-mating of fluid connectors on servers and on racks that house the servers. The design includes two plates. A first plate has a connector channel to guide the connectors of the server through the first plate and spring structures to apply a force to push the connectors of the server toward the center of the connector channel. A second plate has positioning holes around its perimeter for mounting the connectors of the server using the force of the spring structures. The first plate is rotatable around a rotation axis to align the connectors of the server with the connectors of the rack. The second plate may have an elastic layer that is compressed to change a width of the second plate by inserting the second plate to the rack to automatically align the connectors of the server and of the rack in the horizontal direction.
