Pivoting Operation Shaft for Shielded Expansion Card Unlocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In automotive driverless simulation tests, the existing locking mechanisms for expansion cards in servers are cumbersome, especially when larger cards obstruct access to the locking mechanism, making it difficult to securely detach expansion cards without direct manual manipulation.
Innovation Solution
An unlocking structure featuring a base and an operation shaft that pivots from a locking to an unlocking position, allowing the user to apply force to the operation shaft to drive the locking component away from the expansion card, even if the locking mechanism is shielded by the card, facilitating smooth detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking mechanism is disposed on the insert slot to secure expansion cards, then the connection reliability is improved, but the ease of operation deteriorates when the locking mechanism is shielded by large expansion cards
Solution Approach 1:
The operation shaft extends beyond the top surface of the expansion card in the direction perpendicular to the card, providing a new spatial dimension for operation. This allows users to access and operate the locking mechanism from above the card rather than requiring direct access to the side of the insert slot, thereby resolving the shielding problem while maintaining locking reliability
2Ease of operation
If the operation shaft extends beyond the expansion card, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The operation shaft is integrated with the locking component as a unified structure, where the shaft serves dual purposes: it acts as both the operating lever for the locking mechanism and an extension that protrudes beyond the expansion card for user access. This merging of functions avoids adding separate complex mechanisms while achieving improved operability
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
Enables secure and effortless unlocking of expansion cards without direct access to the locking mechanism, ensuring reliable system assembly and disassembly processes.
Implementation Method 1
The operation shaft is adapted to rotate in relative to the base from a locking position to an unlocking position to drive the locking component to be separated from the expansion card
