Server Expansion Card Handle Relocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing complexity and weight of expansion cards in servers due to the need for more electronic components, which is exacerbated by the space occupied by handles and mounting protrusions, limiting the space available for other components.
Innovation Solution
The server design moves the handle from the expansion card to the motherboard, with the mounting protrusion remaining on the expansion card, allowing for labor-saving installation and removal while reducing the overall weight and increasing space on the expansion card for other components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the handle is disposed on the expansion card to facilitate installation, then the installation ease is improved, but the expansion card weight and complexity increase
Solution Approach 1:
The patent applies inversion by relocating the handle from the expansion card to the motherboard, and moving the mounting protrusion from the motherboard to the expansion card. This reverses the conventional arrangement and resolves the contradiction by keeping the installation mechanism functional while removing the weight burden from the expansion card.
Solution Approach 2:
The handle is extracted from the expansion card and transferred to the motherboard. This separation removes the unnecessary weight and complexity from the expansion card while preserving the installation functionality through the remaining mounting protrusion on the expansion card that interfaces with the handle on the motherboard.
2Ease of operation
If the handle structure is made complex to facilitate installation and removal, then the ease of operation is improved, but the space available for other components on the expansion card decreases
Solution Approach 1:
By inverting the positions of the handle and mounting protrusion, the patent eliminates the need for a complex handle structure on the expansion card. The simplified mounting protrusion on the expansion card works with the handle on the motherboard, achieving the same installation facilitation without consuming valuable expansion card space.
3Ease of operation
If the handle and mounting protrusion structure is added to facilitate positioning, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The handle is extracted from the expansion card auxiliary assembly and placed on the motherboard. This reduces the complexity of the expansion card by removing the need for a complex integrated handle structure, while the positioning function is maintained through the simpler mounting protrusion that remains on the expansion card.

AI summary
A server including a motherboard, a first connector, an expansion card, a second connector and an auxiliary assembly. The first connector is disposed on the motherboard. The second connector is disposed on the expansion card and plugged with the first connector. The auxiliary assembly includes a handle and a mounting protrusion. The handle is movably disposed on the motherboard, and the mounting protrusion is disposed on the expansion card. When the handle pushes the mounting protrusion, the handle facilitates the second connector and the first connector to be plugged with or detach from each other, so as to facilitate the motherboard to be electrically connected to or electrically disconnected from the expansion card.
