Modular M.2 PCB Edge Connector Layout for dGPU Versatility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional information handling systems have limited versatility due to unique connections for graphics processing cards on the motherboard, restricting the configuration and efficiency of information processing, storage, and communication.
Innovation Solution
A modular printed circuit board design featuring multiple M.2 connectors aligned on the same edge, allowing for flexible coupling of single-slot M.2 modules, dual-slot dGPU modules, and quad-slot dGPU modules, enabling various configurations such as single-slot SSD modules and dual or quad-slot graphics processing units, while maintaining consistent pitch between connectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If unique connections for graphics processing cards are used on the motherboard, then the connection stability is improved, but the versatility and configurability of the motherboard deteriorates
Solution Approach 1:
The patent implements a universal connector design where M.2 connectors can support multiple functions including graphics processing cards, solid state drives, and other storage devices. The same connector type and interface standard are used across different applications, allowing the motherboard to accommodate various components without requiring unique connections for each function, thus resolving the contradiction between connection stability and versatility
2Ease of manufacture
If fixed motherboard layout is used, then the manufacturing simplicity is improved, but the configurability for different storage and graphics setups deteriorates
Solution Approach 1:
The patent segments the connector layout into modular units with standardized spacing and positioning. The M.2 connectors are arranged in a repeating pattern that can be systematically configured for different applications. This segmentation allows the motherboard to maintain a simple standardized manufacturing process while enabling flexible configurations through the modular arrangement of connectors for different storage and graphics setups
