Stacked Video Transcoding Card Design for Server Space Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The limited interior space in servers restricts the number of transcoding boards that can be accommodated, hindering further performance enhancement of video transcoding.
Innovation Solution
A video transcoding card design featuring a first and second transcoding assembly with multiple boards and connectors, where the second transcoding boards on one circuit board are electrically connected to the first circuit board via main connectors, allowing shared electronic components and increased board count without additional space, effectively doubling the transcoding capacity within the same server space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If more transcoding cards are added to increase transcoding boards, then video transcoding performance is improved, but server interior space is exceeded
Solution Approach 1:
The patent implements a stacked configuration where a second circuit board is positioned above a first circuit board, with transcoding boards on both layers. The connectors extend through both boards to establish electrical connections, effectively nesting one transcoding assembly within another to maximize space utilization in the server interior.
Solution Approach 2:
The patent transitions from a single-plane arrangement of transcoding boards to a three-dimensional stacked configuration. By utilizing the vertical dimension with multiple layers of circuit boards connected through through-board connectors, the system doubles the transcoding board capacity without increasing the horizontal footprint in the server.
2Quantity of substance
If the number of transcoding boards is increased, then video transcoding capacity is improved, but device complexity increases
Solution Approach 1:
The patent divides the transcoding card into modular assemblies, with each circuit board containing a set of transcoding boards that function as independent units. This segmentation allows for easier manufacturing, testing, and maintenance of individual modules while achieving high overall capacity through composition of multiple modules.
Solution Approach 2:
The patent employs universal connectors that extend through both circuit boards to provide common electrical connections for all transcoding boards on the card. This multi-functional connector design simplifies the overall structure by using a single connection mechanism to serve multiple boards across different layers, rather than requiring separate connections for each board.
