Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cables and riser cards are used to connect the fan module to the mainboard, then the connection is stable and reliable, but the production cost increases and the assembly process becomes complicated
Solution Approach 1:
The patent merges the circuit board connection port and the base structure into an integrated assembly. The circuit board is fixed to the base with its connection port extending through the base, eliminating the need for separate cable connections. This integration reduces the number of components and simplifies the assembly process while maintaining reliable electrical connection between the fan module and mainboard
Solution Approach 2:
The patent extracts and eliminates the cables and riser cards from the system by providing a direct mounting structure. The fan module is designed to be mounted directly to the mainboard through the base, with the circuit board connection port establishing electrical connection without requiring intermediate cable components, thus removing the complexity associated with cable management and connection
2Reliability
If cables and riser cards are used to connect the fan module to the mainboard, then the connection is stable, but the production efficiency decreases
Solution Approach 1:
The circuit board and base are merged into a single integrated structure where the circuit board is fixed to the base and the connection port extends through the base. This merging reduces the number of assembly steps by eliminating the need to separately install cables and riser cards, thereby improving production efficiency while maintaining stable electrical connection
3Reliability
If the circuit board is restricted by two restriction structures, then the circuit board deformation is prevented, but the device complexity increases
Solution Approach 1:
The two restriction structures are merged into the base structure itself, rather than being separate components. The base includes integrated features that restrict the circuit board at two different positions, preventing deformation while maintaining a simple overall structure. This integration avoids adding extra components and keeps the device complexity low
