Expansion Card Hook Fixing Mechanism for Signal Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing expansion card holders often result in signal transmission issues due to the tilting of expansion cards when connectors are docked, causing instability and potential disruptions in communication.
Innovation Solution
A hook fixing mechanism with a first and second hook, rotationally mounted on a fixing frame, which includes a resilient member to ensure proper alignment and stability of the expansion card, preventing tilting and ensuring secure docking with connectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the expansion card is fixed in the mounting frame with one side only, then the installation is simple, but the card tilts forward when connector is docked, affecting signal transmission
Solution Approach 1:
The fixing mechanism is divided into multiple independent hooks (first hook and second hook) that separately engage with positioning posts at different locations on the expansion card. This segmentation allows each hook to independently support a specific portion of the card, preventing tilting while maintaining installation simplicity through modular assembly
Solution Approach 2:
The hooks are pre-configured in the mounting frame at specific positions and orientations before the expansion card is installed. When the card is inserted, the hooks automatically engage with the positioning posts on the card's connector, preemptively establishing the correct positional relationship and preventing forward tilt before docking occurs
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The hook fixing mechanism maintains the expansion card's stability, preventing tilting and ensuring reliable signal transmission by securely fixing the card in place, even when docked with connectors, thus enhancing the overall performance and usability.
Implementation Method 1
a resilient member, two ends of which are respectively connected to the fixing frame and the second hook, for rotating the second hook about the second rotating shaft

AI summary
A hook fixing mechanism includes a fixing frame, a first hook, and a second hook. The first hook is rotationally mounted on the fixing frame. A first end of the first hook protrudes from the fixing frame, and a second end of the first hook is movably snapped on the fixing frame. The second hook is rotationally mounted on the fixing frame. A third end of the second hook protrudes from the fixing frame, and a fourth end of the second hook resists against the first hook.
