Display Card Support Bracket for Slot Load and Transport Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing display card slots on circuit boards lack structural support, leading to damage from prolonged weight-bearing and risk of detachment during transportation due to shaking, which can cause collisions and further damage.
Innovation Solution
A fixing device comprising a backplane and a support bracket, where the backplane is fixed on the display card and the support bracket is attached to the circuit board, using engaging parts and locking components to secure the display card in place, distributing the weight and preventing sliding or detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the display card is plugged into the slot on the circuit board without additional support, then the installation is simple, but the slot and circuit board are damaged easily due to bearing the weight of the display card for a long time
Solution Approach 1:
A support bracket is introduced as an intermediary component between the display card and the circuit board. The support bracket bears the weight of the display card, preventing the slot and circuit board from being damaged by prolonged weight-bearing, while still allowing for relatively simple installation.
Solution Approach 2:
The support structure is segmented into separate components: a backplane fixed on the display card and a support bracket fixed on the circuit board, connected through engaging parts. This segmentation allows the support function to be added without complicating the overall installation process significantly.
2Reliability
If the display card is fixed securely to prevent detachment during transportation, then the reliability is improved, but the device complexity increases due to additional support structures and locking mechanisms
Solution Approach 1:
The support bracket integrates multiple functions: it provides structural support, connects to the circuit board, and engages with the backplane through engaging parts. By merging these functions into a single component, the overall device complexity is reduced while maintaining reliable fixation.
Solution Approach 2:
The support bracket serves multiple purposes: bearing weight, preventing detachment during transportation, and providing a mounting structure for the display card. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity.
3Force
If the display card is supported by the support bracket, then the weight distribution is improved, but the device complexity increases due to additional components
Solution Approach 1:
The engaging parts allow for relative movement and adjustment during assembly, enabling the support bracket to adapt to slight variations in positioning. This dynamic characteristic simplifies the assembly process and reduces the need for precision manufacturing, offsetting the added complexity of having additional components.
