Riser Assembly Cable Connection for Flexible Space Utilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic devices with limited space, such as servers, the arrangement of riser cards is restricted by metal pins and connectors on the motherboard, limiting the utilization of internal space since riser cards can only be directly plugged in perpendicular to the motherboard, preventing their placement in redundant spaces away from the motherboard.
Innovation Solution
A riser assembly that includes a first mounting frame and a riser card with a plate body, riser card connector, and expansion card connector, where the riser card is electrically connected to the motherboard via a cable rather than being directly plugged in, allowing flexible placement and utilization of internal space by enabling the riser card to be positioned in idle areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the riser card is directly plugged into the connector on the motherboard, then the electrical connection is reliable, but the arrangement of the riser card is limited and cannot utilize redundant space away from the motherboard
Solution Approach 1:
The riser assembly is divided into separate functional modules: the riser card with expansion card connectors, the mounting frame for structural support, and the cable for electrical connection. This segmentation allows the riser card to be positioned independently from the motherboard connector, enabling flexible placement in redundant spaces while maintaining reliable electrical connection through the cable interface.
Solution Approach 2:
A cable is introduced as an intermediary element between the riser card connector and the motherboard connector. This intermediary allows the riser card to be electrically connected to the motherboard without being physically constrained to a direct perpendicular insertion, thereby enabling the riser card to be arranged in flexible positions including redundant spaces away from the motherboard.
2Productivity
If the riser card is arranged perpendicular to the motherboard, then the connection is straightforward, but the internal space utilization is poor due to limited available space
Solution Approach 1:
The connection structure transitions from a fixed rigid perpendicular arrangement to a dynamic flexible configuration using a cable. This allows the riser card to be positioned in various locations including horizontal or angled orientations in redundant spaces, maximizing space utilization while the cable provides the necessary flexibility to accommodate different installation configurations.
Solution Approach 2:
The riser card arrangement moves from a single-dimension perpendicular-to-motherboard constraint to multi-dimensional positioning freedom. The cable-enabled connection allows the riser card to be placed in redundant spaces at different locations and orientations (horizontal, angled, or perpendicular), effectively utilizing three-dimensional internal space that would otherwise be inaccessible.
