PCI-E Connector Linkage Button for Obstructed Card Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The advancement of technology has made it difficult for users to directly press the rotating button of a PCI-E connector due to the presence of high-efficiency heat sinks or elements with new functions, complicating the removal of expansion cards.
Innovation Solution
A circuit board module design featuring a remote press button and linkage mechanism that allows the rotating button to be driven remotely through a linkage system, including a bracket and linkage segments aligned along different axes, enabling the rotating button to be operated from a distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the rotating button is located at the end of the connector, then the connector structure is simple, but users cannot directly press the rotating button when heat sinks or new function elements are present
Solution Approach 1:
A linkage mechanism comprising a first segment and a second segment is introduced as an intermediary between the press button and the rotating button. The first segment extends along a first axis and links to the rotating button, while the second segment extends along a second axis and links to the press button, enabling indirect actuation of the rotating button when directly accessible
Solution Approach 2:
The linkage mechanism utilizes spatial arrangement by extending segments along different axes (first axis and second axis) to transmit actuation force from the press button location to the rotating button location, effectively operating in multiple dimensional directions to overcome the blocking obstacle
2Ease of operation
If a linkage mechanism is introduced to enable remote operation, then the rotating button becomes accessible, but the device complexity increases
Solution Approach 1:
The linkage mechanism is divided into distinct segments (first segment and second segment) that can be independently positioned and connected. Each segment serves a specific function in transmitting motion along different axes, making the complex mechanism more manageable and easier to assemble
Solution Approach 2:
The linkage mechanism incorporates movable connections between segments that allow dynamic adjustment during operation. The segments can move relative to each other along specified axes, enabling the mechanism to adapt to the spatial relationship between the press button and rotating button while maintaining functional integrity
