Expansion Slot Support Assembly With Accessible Rotating Latch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking latch mechanisms in computing devices are obstructed by large installable components, making it difficult to access and remove them, especially when multiple components are installed, and they lack structural support for the increasing size and weight of these components.
Innovation Solution
A supporting assembly with a rotatable latch bar and control knob is positioned adjacent to the expansion slot, allowing easy insertion and extraction of installable components by engaging and disengaging the latch bar through a coupling arm and control knob mechanism, which is not obstructed by the component, and is capable of supporting larger components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional locking latch mechanism is used to secure installable components, then the component can be rigidly secured in the expansion slot, but the latch becomes obstructed and difficult to access when large components are installed
Solution Approach 1:
The latch bar is repositioned from a traditional side-mounted location to a top-mounted position above the expansion slot. This dimensional change allows the control knob to be accessed from the top surface of the motherboard rather than from the side, eliminating obstruction by large installable components while maintaining the securing function.
Solution Approach 2:
A control knob is introduced as an intermediary mechanism to operate the latch bar. The control knob provides a user-friendly interface that rotates to drive the latch bar between engaged and disengaged positions, making the securing and releasing operations easier while keeping the latch mechanism itself out of the way.
2Device complexity
If the latch mechanism is positioned close to the expansion slot for compact design, then device complexity is reduced, but the control mechanism becomes obstructed by installable components
Solution Approach 1:
The control mechanism is moved to a different spatial dimension (top surface) rather than being positioned adjacent to the expansion slot on the same plane. This allows the latch bar to remain close to the slot for structural simplicity while the control knob is accessible from above.
3Reliability
If traditional securing mechanisms are used, then installable components can be held in place, but they lack structural support for increasing size and weight of components
Solution Approach 1:
The supporting member and latch bar are merged into a single integrated structure. The supporting member provides structural support for large, heavy components while the latch bar provides the securing mechanism, combining both functions into one unified assembly that reinforces rather than competes with the motherboard structure.
4Strength
If the latch bar is made robust to support larger components, then structural support capacity increases, but the mechanism becomes more complex and harder to operate
Solution Approach 1:
The supporting member and latch bar are combined into a single integrated component, eliminating the need for separate complex mechanisms. The unified structure provides both support and securing functions through a simple rotational operation of the control knob.

AI summary
Examples of a supporting assembly for supporting an installable component are described. The supporting assembly comprises a supporting member. The supporting assembly may further include a latch bar extending longitudinally to support the installable component. The supporting assembly may further include a coupling arm and a control knob. In an example, the control knob may be rotatable, and is to control rotation of the latch bar.
