Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Server modules face challenges in accommodating expansion components of varying dimensions, requiring a solution to securely and efficiently integrate different-sized expansion cards within a computer system while maintaining compatibility with existing standards like PCI.
Innovation Solution
A holding component with a riser card and a support component that utilize centering means, slot brackets, and securing devices to facilitate the plug-in and securement of expansion components, allowing for variable dimensions and standards compliance, with the riser card establishing a plug connection and the support component providing a form-fit arrangement and backplane connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-size bracket is used to hold expansion cards, then the structure is simple, but it cannot accommodate expansion cards of different dimensions
Solution Approach 1:
The bracket is designed with a pivotable support component that can rotate between a received position and a blocked position. This dynamic movement allows the same bracket structure to adapt to different expansion card sizes by adjusting the support component's angle, resolving the contradiction between fixed structure and variable accommodation capability
Solution Approach 2:
The bracket is divided into multiple functional components: a base component, a support component with fastening point, and a blocking component. This segmentation allows each part to perform its specific function independently, enabling the overall structure to accommodate various card sizes while maintaining structural simplicity
2Reliability
If expansion cards are securely fastened to prevent slippage, then reliability is improved, but the structure becomes more complex
Solution Approach 1:
The support component automatically performs both support and blocking functions through its pivotable movement. When the support component is in the received position, it naturally provides support; when pivoted to the blocked position, it automatically prevents slippage and lifting. This self-service mechanism achieves reliable securing without requiring additional complex components
Solution Approach 2:
The support component and blocking component are merged into a single pivotable element. This unified component simultaneously provides support function and blocking function at different positions, achieving reliable card fixation while minimizing structural complexity through functional integration
3Adaptability or versatility
If multiple separate components are used to support different card sizes, then adaptability is improved, but device complexity increases
Solution Approach 1:
The bracket is designed as a universal structure where the pivotable support component can serve multiple functions: supporting small cards, supporting large cards, and blocking cards to prevent slippage. This multi-functionality allows a single bracket design to accommodate variable expansion card dimensions without requiring multiple separate components for different card sizes
