PCI Card Mounting Bracket with Elastic Snap-Fit Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for installing PCI cards using screws are cumbersome and prone to errors, such as lost screws, and space constraints become significant issues as more components are added within the computer enclosure, potentially damaging the printed circuit board.
Innovation Solution
A mounting apparatus comprising a mounting bracket with elongated slots and a securing member that uses a pivoting mechanism with elastic engagement to securely attach and detach PCI cards without the need for screws, utilizing a combination of pivoting holes, pressing portions, and elastic tabs for easy assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws and screwdrivers are used to install PCI cards, then the PCI cards can be securely mounted, but the installation process becomes tedious and time-consuming
Solution Approach 1:
The patent removes the screw and screwdriver components from the installation system, replacing them with a snap-fit mounting mechanism. The PCI card is secured through direct engagement with the mounting bracket using elastic tabs that click into place, eliminating the need for separate fastening tools and significantly reducing installation time while maintaining secure mounting.
Solution Approach 2:
The mounting mechanism is designed to be self-servicing, where the elastic tabs on the mounting bracket automatically engage with the PCI card edges when inserted. The system self-secures without requiring external tools or manual screw tightening, making the installation process intuitive and rapid while ensuring reliable fixation.
2Reliability
If screws are used to mount PCI cards, then secure attachment is achieved, but screws can be lost or fall on the PCB causing damage
Solution Approach 1:
The patent extracts the loose screw fasteners from the system and replaces them with an integrated snap-fit mechanism where the mounting bracket directly engages with the PCI card. This eliminates the risk of screws being lost or accidentally dropped onto the PCB, as there are no separate fastening components that can detach and become hazards.
Solution Approach 2:
The mounting function and the securing function are merged into a single integrated mechanism. The elastic tabs on the mounting bracket combine the functions of positioning and securing the PCI card in one component, eliminating the need for separate screws that could be lost or cause damage to the PCB.
3Adaptability or versatility
If more components are installed within the computer enclosure, then functionality is enhanced, but space becomes constrained
Solution Approach 1:
The mounting bracket incorporates elastic tabs that provide dynamic flexibility during installation. These tabs can deform elastically to accommodate the PCI card during insertion and then snap into a locked position, providing secure mounting without requiring additional space. The dynamic nature of the elastic engagement allows for compact design while maintaining secure attachment.
Solution Approach 2:
The mounting bracket is designed with a compact structure where the elastic tabs are integrated within the bracket body. The PCI card nests into the bracket structure, with the elastic tabs providing internal securing mechanisms that do not protrude outward, thus minimizing the overall space occupied in the computer enclosure while allowing multiple components to be installed.
