Modular PCIe Riser Bracket for Multi-Size Card Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current riser brackets for computer servers are limited to supporting specific sizes of PCIe expansion cards, requiring different brackets for each size, which restricts adaptability and increases complexity when adding various types of cards.
Innovation Solution
A modular riser bracket assembly with two half-components that can be assembled to support different types of PCIe cards, including full-height and half-height cards, using registration features and locking mechanisms to secure the cards in place, allowing for flexible installation without the need for multiple brackets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single riser bracket is designed to support multiple PCIe card sizes, then adaptability is improved, but device complexity increases
Solution Approach 1:
The riser bracket is divided into a first component half and a second component half, each designed to support different PCIe card sizes. The component halves can be separately attached to the riser board, allowing the system to accommodate full-height and half-height cards without requiring a completely different bracket design for each card type.
Solution Approach 2:
The riser bracket assembly is designed with universal support for multiple PCIe card formats (full-height full-length, half-height full-length, and half-height half-length cards) through a single integrated system. The registration features and component halves work together to provide multi-functional capability, eliminating the need for multiple specialized brackets.
2Manufacturing precision
If different riser brackets are used for different PCIe card sizes, then manufacturing precision is maintained, but ease of operation deteriorates
Solution Approach 1:
A single riser bracket assembly with interchangeable component halves provides universal support for different PCIe card sizes, eliminating the need for users to select and install different brackets. The registration features ensure precise alignment and secure attachment while maintaining ease of operation through a unified interface.
Solution Approach 2:
The functionality of multiple specialized riser brackets is merged into a single assembly with detachable component halves. This combination allows the system to maintain the manufacturing precision of specialized brackets while providing the ease of operation of a universal design, as users only need to attach the appropriate component half rather than更换 entire brackets.
3Reliability
If multiple specialized riser brackets are maintained for different card types, then reliability is improved, but device complexity increases
Solution Approach 1:
The riser bracket is segmented into interchangeable component halves that can be selectively attached to the riser board. Each component half is optimized for specific PCIe card sizes, maintaining the reliability of specialized designs while reducing overall system complexity by consolidating multiple bracket types into a single modular assembly.
Solution Approach 2:
The riser bracket assembly incorporates dynamic reconfigurability through detachable component halves that can be attached or removed based on the PCIe card installation requirements. This dynamic capability allows the system to adapt to different configurations while maintaining reliable support for each card type, eliminating the need to maintain multiple complete bracket assemblies.
