Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to fix PCIe cards, then the card is securely fixed, but the operation becomes inconvenient and occupies extra space
Solution Approach 1:
The patent extracts the fastening function from traditional screws and separate fastening components, integrating it directly into the PCIe card itself through elastic members (springs) that are built into the card structure. This eliminates the need for external fasteners and simplifies the overall assembly.
Solution Approach 2:
The PCIe card performs its own fastening function through integrated elastic members that automatically clamp onto the circuit board when inserted. The card essentially fixes itself without requiring external screws or additional fastening operations, making installation simple and space-efficient.
2Reliability
If screws are used to fix PCIe cards, then the card is securely fixed, but the device complexity increases
Solution Approach 1:
The patent merges the fastening function with the PCIe card structure itself, combining what were previously separate components (card, screws, fastening mechanisms) into a single integrated unit. The elastic members are built into the card, eliminating the need for separate fastening parts.
Solution Approach 2:
The patent removes screws and separate fastening components from the system, extracting the fastening function and embedding it directly into the PCIe card structure through integrated elastic members, thereby reducing overall device complexity.
3Reliability
If traditional fastening methods are used, then secure fixation is achieved, but space utilization is reduced
Solution Approach 1:
The patent combines the fastening mechanism with the PCIe card structure itself, eliminating the need for separate screws and fastening components that would occupy additional space. The elastic members are integrated into the card, achieving secure fixation without extra space consumption.
Solution Approach 2:
The patent extracts and removes traditional screw fasteners and separate fastening components from the system, replacing them with space-efficient integrated elastic members built into the PCIe card structure, thereby improving space utilization.
