Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the expansion card is attached to the riser card along the direction parallel to the main board, then the connection is stable, but the operation space is insufficient and it is inconvenient to attach/detach the expansion card
Solution Approach 1:
The riser card is designed to be rotatable relative to the main board, transitioning from a fixed perpendicular position to a rotatable position parallel to the main board. This dynamic adjustment allows the expansion card to be attached in a direction perpendicular to the main board when space is limited, and rotated to a parallel position for convenient access during attachment/detachment operations
Solution Approach 2:
The invention introduces rotational movement in a third dimension, allowing the riser card to change its orientation from perpendicular (first direction) to parallel (second direction) relative to the main board. This dimensional change enables the expansion card to be attached in a space-efficient perpendicular direction while providing adequate operation space when rotated to the parallel position
2Area of stationary object
If the riser card is fixed perpendicular to the main board, then the space utilization is efficient, but the expansion card cannot be conveniently accessed for attachment/detachment
Solution Approach 1:
The riser card is designed with rotational capability, allowing it to transition from a fixed perpendicular position (space-efficient) to a rotatable parallel position (access-efficient). The rotation mechanism enables the system to adapt its configuration based on operational needs, maintaining space efficiency when not in use while providing easy access during attachment/detachment operations
3Area of stationary object
If the expansion slot is located in a limited space area, then the computer device is compact, but the expansion card installation is interfered with by other components
Solution Approach 1:
The invention resolves the space constraint by introducing rotational movement, allowing the expansion card to be installed in a direction perpendicular to the main board when space is limited. The riser card can rotate to a parallel position to provide adequate installation space when needed, effectively utilizing three-dimensional space rather than being constrained to a single plane
Solution Approach 2:
The dynamic rotation capability allows the expansion card installation configuration to adapt to different spatial constraints. The system can switch between a compact perpendicular configuration for space-constrained environments and a parallel configuration for easier access, providing versatility in installation approaches

AI summary
A riser card rotating module is disposed adjacent to an expansion slot and includes a guide plate, a fixing plate, a riser card, a first pivot member and a second pivot member. The guide plate has a first guide rail parallel to a plug-unplug direction of the expansion slot and a second guide rail perpendicular to the plug-unplug direction of the expansion slot, wherein the first guide rail and the second guide rail communicate with each other to form a T-shape. The riser card is fixed on the fixing plate and has an electric connector. An end of the first pivot member is fixed on the fixing plate. Another end of the first pivot member is movably disposed on the guide plate. An end of the second pivot member is fixed on the fixing plate. Another end of the second pivot member is movably disposed on the guide plate.
