Adjustable Support for Expansion Card Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional supports for graphics cards are not adaptable to different motherboard specifications, leading to instability due to changes in the position of the power supply and electrical connectors, making them unsuitable for use across various motherboard configurations.
Innovation Solution
An adjustable support system that secures to both the motherboard and chassis via existing through holes, allowing for stable support of expansion cards regardless of motherboard specification changes, by having a side fixed to the motherboard and chassis, thus maintaining consistent connector positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional support is fixed to the chassis to support the circuit board assembly, then the circuit board assembly is supported, but the support cannot be used across different motherboard specifications due to position changes
Solution Approach 1:
The support is designed with a universal mounting mechanism that attaches to both the motherboard and chassis simultaneously. The support includes a first end that mounts to the motherboard and a second end that supports the circuit board assembly, creating a multi-functional component that works across different motherboard specifications by leveraging the fixed spatial relationship between the motherboard and chassis
Solution Approach 2:
The support acts as an intermediary element between the motherboard and chassis, transferring the stability of both structures to support the circuit board assembly. By anchoring to both the motherboard and chassis, the support creates a stable triangular structure that compensates for position variations in electrical connectors across different motherboard specifications
2Adaptability or versatility
If the position of the electrical connector changes with motherboard specification, then different motherboard configurations are supported, but the distance between the circuit board assembly and chassis changes, making the support too short or too long
Solution Approach 1:
The support structure serves multiple functions: it mounts to the motherboard at varying positions, anchors to the chassis at a fixed position, and supports the circuit board assembly. This multi-functionality allows the same support design to work across different motherboard specifications while maintaining stability
Solution Approach 2:
The support design accommodates dynamic position changes of electrical connectors on the motherboard by maintaining a fixed mounting position on the chassis. The support effectively absorbs the positional variations through its dual-anchoring mechanism, creating a stable support structure regardless of connector position changes

AI summary
An electronic device including a chassis, a motherboard, an expansion card and a support. The motherboard is disposed in the chassis. The expansion card includes a circuit board assembly and a fixing plate. The circuit board assembly is fixed to a side of the fixing plate. The circuit board assembly is electrically connected to the motherboard and is fixed to the chassis via the fixing plate. A side of the support supports a side of the circuit board assembly that is located farthest from the fixing plate. A side of the support that is located farthest from the circuit board assembly is fixed to the motherboard and the chassis.
