Expansion Card Fixing Structure with Integrated Cover Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing expansion card fixing structures in servers require multiple complex steps for installation, including opening the cover, unhooking, and pressing the buckle, making the operation process cumbersome.
Innovation Solution
The proposed expansion card fixing structure includes a guide track, a limiting element, a handle, a resilient member, and an expansion plate, which work together to simplify the insertion and removal of expansion cards by using a movable connection between the expansion plate and the guide track, allowing for easy fixation and unfastening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the prior art pluggable structure is used for expansion card installation, then the expansion card can be fixed securely, but the installation process becomes complicated requiring multiple steps including opening cover, unhooking, and pressing buckle
Solution Approach 1:
The patent combines the cover opening function and the card fixation function into a single integrated structure. The cover itself incorporates the fixation mechanism, eliminating the need for separate unhooking and pressing operations. When the cover is opened or closed, it automatically performs both the access and fixation/unfixation operations in one motion.
Solution Approach 2:
The cover is designed to serve multiple functions: it protects the expansion card slot, provides access to the slot, and performs the fixation and unfixation of the expansion card. By making the cover multi-functional, the patent eliminates the need for dedicated fixation components and complex multi-step operations.
2Stability of the object's composition
If the prior art pluggable structure with card hook is used, then the expansion card is securely fixed in the chassis, but the operation process requires multiple steps such as opening cover, unhooking, and pressing buckle
Solution Approach 1:
The patent extracts the dedicated card hook mechanism from the fixation system and replaces it with the cover itself performing the fixation function. By removing the separate card hook component and its associated operation steps, the patent simplifies the overall structure while maintaining fixation stability through the cover's integrated mechanism.
Solution Approach 2:
Instead of using a separate hook that needs to be unhooked and then re-engaged, the patent inverts the approach by making the cover itself the fixation element. The cover's opening and closing motions directly perform the unfixation and fixation operations, reversing the traditional sequence where fixation and access operations are separate.
