Motherboard Connector Latch for Obstructed Interface Card Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increased size of heat dissipation components on interface cards obstructs the latch, making it inconvenient to press and prone to detachment from the socket, especially due to high temperatures and limited material selection.
Innovation Solution
A connector design with a pivotally mounted latch featuring a pressing member and supporting member, allowing easy finger access and robust mechanical strength, with a gap between the pressing member and interface card to prevent obstruction, and a supporting member that rests on the circuit board to stabilize the latch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If heat dissipation components are increased on interface cards to improve operational efficiency, then operational efficiency is improved, but the overall size increases and obstructs the latch mechanism
Solution Approach 1:
The pressing member is extended outward from the side of the latch body to a position outside the socket, changing the spatial dimension of the pressing interface. This allows the pressing area to be relocated away from the obstruction zone created by heat dissipation components, enabling convenient latch operation despite the presence of large interface cards with extensive heat dissipation components.
2Volume of stationary object
If the latch is placed close to the high-temperature interface card, then space is saved, but material selection is limited due to temperature constraints
Solution Approach 1:
The latch structure is segmented into distinct functional components: the latch body for engagement, the pressing member for operation, and the supporting member for stability. This segmentation allows each component to be optimized independently, enabling the use of temperature-resistant materials in the latch body while maintaining space efficiency.
3Ease of manufacture
If the pivot is simply placed in an extension portion to reduce manufacturing cost, then manufacturing cost is reduced, but the latch easily detaches when pressed too hard
Solution Approach 1:
The supporting member is designed to contact the circuit board beforehand, providing a counterbalancing support force before excessive pressing occurs. This pre-positioned support prevents the latch from detaching by distributing the pressing force, allowing the simple pivot design to maintain both low manufacturing cost and high reliability.
4Ease of operation
If the pressing member is extended outward to improve pressing convenience, then ease of operation is improved, but the device complexity increases
Solution Approach 1:
The pressing member is merged with the latch body as an integrated structure, where the pressing member serves as an extension of the latch body rather than a separate component. This merging approach improves pressing convenience while minimizing the increase in device complexity by combining functions into a unified structure.

AI summary
A motherboard includes a circuit board and a connector mounted on the circuit board. The connector comprises a socket and a latch pivotally mounted on one end of the socket. The latch comprises a body, a pressing member connected to one side of the body and extending outward from one side of the body to the outside of the socket, exposing an area from a side of the interface card for finger pressing. The supporting member is connected to another side of the body, and when the pressing member is pressed, it drives the body to pivot and causes the pushing portion to lift the interface card, and the supporting member stop the body from pivoting by resting against the circuit board.
