Graphics Card Support Assembly with Adjustable Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing card slots on mainboards inadequately support larger and heavier graphics cards, leading to potential poor contact and vulnerability to impacts or shocks, which can result in short circuits and damage.
Innovation Solution
A support assembly with a positioning frame, adjustable support members, and elastic holding portions that securely fix graphics cards of varying sizes by abutting against their ends, ensuring stable and firm installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If existing card slots are used to support graphics cards, then the structure is simple, but the support capability is insufficient for larger and heavier graphics cards
Solution Approach 1:
The support assembly is divided into multiple independent components including positioning base plate, positioning pin, positioning member, adjusting member, and elastic holding portion. Each component performs a specific function, allowing the system to support larger graphics cards while maintaining manageable complexity through modular design
Solution Approach 2:
The adjusting member is designed to be movable along the positioning member, allowing dynamic adjustment of the support position to accommodate different graphics card sizes. The elastic holding portion provides flexible holding force that adapts to different card weights, resolving the contradiction between support capability and structural fixedness
2Reliability
If graphics cards are firmly fixed with support assembly, then contact reliability improves, but installation complexity increases
Solution Approach 1:
The elastic holding portion automatically adjusts and applies holding force to the graphics card without requiring additional fastening operations. The positioning pin and positioning member work together to self-align and secure the card, maintaining high contact reliability while keeping installation simple
Solution Approach 2:
Different parts of the support assembly have specialized functions: the positioning base plate provides stable mounting, the positioning pin ensures precise alignment, and the elastic holding portion provides adaptive securing force. This localized specialization achieves reliable fixation without requiring complex overall structure
3Adaptability or versatility
If support assembly is designed for adjustable positioning, then adaptability to different card sizes improves, but device complexity increases
Solution Approach 1:
The adjusting member can move along the positioning member to different positions, allowing the support assembly to adapt to various graphics card lengths and sizes. This single dynamic adjustment mechanism provides versatility without requiring multiple complex configurations
Solution Approach 2:
The support assembly is designed to universally accommodate different graphics card specifications through the adjustable positioning mechanism. The same basic structure can support various card sizes by simply adjusting the member position, avoiding the need for multiple specialized assemblies
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
The support assembly effectively secures graphics cards of different sizes and specifications, preventing damage from impacts and ensuring reliable contact with the mainboard, thereby reducing the risk of short circuits and enhancing overall system stability.
Implementation Method 1
a first elastic member connects the positioning pin and the positioning member in the first direction. The switch can drive the positioning pin to move in the first direction through elastic deformation of the first elastic member
Implementation Method 2
a second elastic member connects the adjusting member and the positioning member in the second direction, and the second elastic member permanently pushes the adjusting member to return to the second position

AI summary
A support assembly and a chassis structure for positioning and support of large and heavy computer cards. The chassis structure includes a housing, a main board in the housing, and a graphics card slot on the main board. The housing includes a positioning frame on the main board and the support assembly on the frame. The support assembly is detachable. The support assembly includes positioning base plate, positioning member, and adjusting member. The positioning member is on a base which is detachable from the positioning frame. The adjusting member is moveable. The positioning member includes a first support portion, the adjusting member includes a second support portion. Depending on card size, either the first support portion or the second support portion abuts against an end side of a graphics card away from the graphics card slot, to position and firmly hold in place graphics cards of different sizes.
