Interface Card Fastener With Elastic Lift for Tool-Free Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screw locking structures for interface cards in notebook computers are inconvenient and prone to causing short circuits, and the weight of interface cards with heat sinks makes them difficult to remove due to insufficient elastic restoring force in the connector.
Innovation Solution
A positioning fastener with a latching mechanism and lifting mechanism, utilizing transverse and longitudinal elastic members to assist in unlocking and lifting the interface card, allowing it to tilt upward and overcome the weight of heat sinks for smooth removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a screw locking structure is used to secure the interface card, then the interface card is firmly fixed and stable, but it requires hand tools for removal and may cause short circuits if screws become loose or fall
Solution Approach 1:
The patent replaces the screw locking mechanism with a snap-fit latching mechanism. The latching member engages with the interface card through elastic deformation and mechanical interlocking, eliminating the need for screwdrivers while maintaining secure fixation. The latching member can be easily actuated to release the card without tools.
Solution Approach 2:
The latching member incorporates an operating portion that allows users to easily actuate the locking and unlocking actions. The elastic member automatically returns the latching member to its engaged position after release, providing self-service functionality without requiring additional tools or complex mechanisms.
2Temperature
If the interface card weight plus heat sink weight is high, then effective heat dissipation is achieved, but the elastic restoring force of the connector is insufficient to lift the card for removal
Solution Approach 1:
The pushing block acts as an intermediary mechanism between the elastic restoring force and the interface card. It concentrates and transmits the upward force from the elastic member to the card's board edge, amplifying the lifting effect and overcoming the weight of heat sinks that would otherwise prevent card removal.
Solution Approach 2:
The patent introduces a vertical lifting dimension to the removal process. Instead of relying solely on horizontal pulling force, the pushing block generates upward vertical motion that tilts the card upward, creating a mechanical advantage that overcomes the downward force of gravity on heavy heat sinks.
3Stability of the object's composition
If the latching member blocking structure is present during locked state, then secure locking is achieved, but it suppresses the pushing block from moving upward during unlocking
Solution Approach 1:
The latching member is designed to transition between static locked and dynamic unlocked states. During unlocking, the latching member rotates about its shaft, dynamically changing its position from blocking to non-blocking, allowing the pushing block to move upward without requiring complex disassembly or additional release mechanisms.
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
Facilitates easy and secure removal of interface cards without tools, preventing potential short circuits and ensuring effective heat dissipation.
Implementation Method 1
the pushing block will not be suppressed by the blocking structure of the latching member and the preset interface card and will be elastically reset upward through the compressed longitudinal elastic member located on the bottom side of the pushing block

AI summary
An interface card positioning fastener with elastic push assistance includes a base with a receiving slot and a storage slot inside, a locking mechanism installed in the receiving slot and having a latching member corresponding to the board edge of an interface card for locking, and a lifting mechanism installed in the storage slot and having a pushing block capable of elastically pushing the board edge of the interface card upward after the latching member and the board edge of the interface card are unlocked so that the preset interface card can form an upward tilt state to facilitate smooth removal of the interface card.
