Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the server uses dedicated spaces for PCIe cards or OCP cards, then the interface connection is stable and reliable, but the adaptability and space utilization are reduced
Solution Approach 1:
The adapter device enables a PCIe slot to serve multiple functions by converting it to accept both PCIe cards and OCP cards. The adapter circuit board with OCP interface and PCIe interface allows the same physical slot to adapt to different card types, achieving multi-functionality without requiring separate dedicated spaces for each card type.
Solution Approach 2:
The adapter device acts as an intermediary between the PCIe slot and OCP cards. It includes an OCP interface that receives OCP cards, an adapter circuit board that provides electrical connection, and a PCIe interface that connects to the PCIe slot, thereby mediating the connection between incompatible interfaces.
2Productivity
If the server uses dedicated spaces for PCIe cards or OCP cards, then the installation structure is simple, but the space utilization and configuration flexibility are reduced
Solution Approach 1:
The adapter device employs a nested structure where the OCP interface and adapter circuit board are integrated within a compact housing that fits into the PCIe slot. The adapter circuit board is electrically connected to both the OCP interface and the PCIe interface, creating a nested arrangement that maximizes space utilization while maintaining structural integrity.
3Adaptability or versatility
If the adapter device is installed in the PCIe bracket, then the interchangeability between PCIe and OCP cards is improved, but the device complexity increases
Solution Approach 1:
The adapter device is segmented into distinct functional modules: the OCP interface for receiving OCP cards, the adapter circuit board for electrical connection, and the PCIe interface for connecting to the PCIe slot. This segmentation allows each module to be optimized independently while maintaining overall interchangeability functionality.

AI summary
An adapter device enabling a peripheral component interconnect express (PCIe) slot in a server to additionally accept an open compute project (OCP) card includes a bracket assembly compatible with an OCP card and a server. The adapter device comprises a chassis, a front-end bracket, an adapter assembly, and a rail assembly. The front-end bracket defines a first inserting port for OCP card insertion, the adapter assembly comprises OCP interface, adapter circuit board, and PCIe interface. The PCIe interface is connected to the adapter circuit board, and the adapter circuit board provides electrical connection and conversion between OCP interface and PCIe interface. The rail assembly between the front-end bracket and the OCP interface carries in the OCP card when the card is inserted.
