Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual cable reconnection is used for switching GPU topology structures, then topology switching flexibility is achieved, but cable damage and interface damage risk increase
Solution Approach 1:
The patent introduces a connector circuit board as an intermediary component between the GPU board and the cable. This connector circuit board includes a first connector that interfaces with the cable and a second connector that interfaces with the GPU board, thereby mediating the connection and protecting both the cable and GPU interfaces from damage during topology switching operations
Solution Approach 2:
The patent segments the connection system into distinct components: the GPU board with its connectors, the connector circuit board as a separate module, and the cable. This segmentation allows the connector circuit board to be independently designed and optimized for protection and connectivity, separating the protective function from the connection function
2Adaptability or versatility
If multiple cables of varying lengths are used for different machine types, then topology configuration adaptability is achieved, but operation complexity increases
Solution Approach 1:
The connector circuit board is designed as a universal component that can support multiple topology configurations (1+1, 1+N, N+N) through its connector arrangement. The first connector and second connector can be connected in different configurations to accommodate various machine types, allowing a single universal component to replace multiple specialized cable assemblies
Solution Approach 2:
The patent enables dynamic reconfiguration of the connection topology by allowing the connector circuit board to be connected in different configurations. The system can dynamically switch between 1+1, 1+N, and N+N topologies by changing the connection state of the connectors, providing operational flexibility without requiring physical cable changes
3Adaptability or versatility
If frequent manual cable reconnection is performed for topology switching, then machine topology adaptability is achieved, but time consumption and damage risk increase
Solution Approach 1:
The connector circuit board is pre-assembled with the appropriate connectors and connection configurations before being installed on the GPU board. This preliminary preparation eliminates the need for on-site cable assembly and disassembly operations, reducing the time required for topology switching while maintaining adaptability
