Double-Layer Rack With Modular OCP Network Card Accommodation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data processing unit products in servers are inflexible, requiring multiple production lines and specific designs for different modules, making it challenging to switch between various configurations based on user requirements.
Innovation Solution
A double-layer rack design that includes a PCIe card frame, a network card frame, a PCIe riser card, and a network card connector assembly, allowing for selective accommodation of one OCP network card, two OCP network cards, or one data processing unit through the use of a blocker component and a divider plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed configuration products with specific module designs are used, then product reliability is improved, but adaptability deteriorates as multiple production lines are required for different modules
Solution Approach 1:
The rack design incorporates a universal mounting structure that can accommodate multiple types of modules (OCP network cards, SFF network cards, and data processing units) through a single standardized interface. The rack includes adjustable mounting positions and universal connector assemblies that work with different module types, eliminating the need for separate production lines for each module configuration.
Solution Approach 2:
The rack incorporates adjustable and reconfigurable mounting mechanisms that allow dynamic reconfiguration of module positions and configurations. The mounting structure includes adjustable arms, reconfigurable connector assemblies, and movable support elements that enable the rack to adapt to different module types and configurations without requiring physical redesign of the rack itself.
2Manufacturing precision
If multiple production lines are established for different modules, then manufacturing precision is improved for specific configurations, but device complexity increases
Solution Approach 1:
The rack is divided into modular components including separate mounting assemblies, connector assemblies, and support structures that can be independently manufactured and assembled. This segmentation allows each component to be optimized for manufacturing while maintaining overall system flexibility. The connector assembly is designed as a separate module that can be precision-manufactured once and then reused across different configurations.
Solution Approach 2:
A universal mounting structure and standardized connector assembly are designed to work with multiple module types through a single production line. The universal design incorporates standardized interfaces, adjustable mounting positions, and generic support structures that accommodate OCP network cards, SFF network cards, and data processing units without requiring configuration-specific manufacturing.
3Ease of manufacture
If product-specific design is adopted, then ease of manufacture is improved for specific configurations, but adaptability deteriorates as switching between modules becomes challenging
Solution Approach 1:
The rack is pre-configured with universal mounting structures, adjustable support elements, and pre-positioned connector assemblies that are designed to accommodate multiple module types from the outset. This preliminary design of flexible mounting mechanisms eliminates the need for post-manufacturing adjustments or reconfiguration, making both manufacturing and module switching easier while maintaining adaptability.
Solution Approach 2:
The rack incorporates dynamic mounting mechanisms including adjustable arms, movable support structures, and reconfigurable connector assemblies that can be easily modified to accommodate different module types. These dynamic elements allow the rack to transition between different configurations without requiring physical redesign or complex manufacturing processes for each specific configuration.

AI summary
A double-layer rack includes a PCIe card frame, a network card frame, a PCIe riser card and a network card connector assembly. The PCIe card frame is stacked on the network card frame. The network card frame has a network card accommodation space for selectively receiving one OCP network card, two OCP network cards or one data processing unit. The PCIe riser card is disposed in the PCIe accommodation space. The network card connector assembly is disposed in the network card accommodation space. The double-layer rack further includes a blocker component and a divider plate selectively and removably disposed on the network card frame, so that the network card accommodation space forms various accommodation space configurations for selectively receiving the one OCP network card, the two OCP network cards or the one data processing unit.
