Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing general-purpose rack systems face challenges with complex cabling between compute nodes and switches, leading to time-consuming and labor-intensive maintenance and deployment, especially as the scale of nodes and switches increases.
Innovation Solution
A switch subrack and cabinet system that facilitates blind mating of switches, reducing the need for complex cabling by converting the switch's connection port into a blind-mate interface using a transfer module, which includes signal and power transfer modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional optical fiber and power cable connections are used between nodes and switches, then the system can be assembled, but the cabling becomes complex and maintenance becomes time-consuming and labor-consuming
Solution Approach 1:
A transfer module is introduced as an intermediary component between the switch and the cabinet system. This transfer module includes a blind-mate connector that interfaces with the cabinet system and converts traditional connection ports into blind-mate interfaces, eliminating the need for complex optical fiber and power cable connections while maintaining system functionality
Solution Approach 2:
The patent replaces the traditional mechanical cabling system (optical fibers and power cables) with a blind-mate electrical connection system. The blind-mate connector establishes direct electrical connections between the switch and cabinet system, substituting the mechanical process of cable routing and connection with an automated electrical mating process
2Productivity
If the deployment scale of nodes and switches is increased, then the system capacity is improved, but the quantity of cables increases and cable deployment becomes more difficult
Solution Approach 1:
The transfer module serves as a scaling-enabling intermediary that provides standardized blind-mate interfaces. This allows the system to expand in capacity by adding more switches and nodes without proportionally increasing cable complexity, as each new component connects through the same standardized interface rather than requiring individual cable routing
3Extent of automation
If traditional connection ports are used on switches, then the switches can connect to nodes, but automatic maintenance is difficult
Solution Approach 1:
The blind-mate connector enables self-service maintenance by automatically establishing and maintaining electrical connections between the switch and cabinet system. The connector's design allows for automatic mating and electrical contact establishment, eliminating the need for manual cable connection and enabling automated maintenance processes
Solution Approach 2:
The patent replaces manual mechanical cable connection with an automated electrical connection system. The blind-mate connector's design allows for automatic alignment and electrical contact when the switch is installed in the cabinet, substituting the manual cable routing and connection process with an automated mechanical-electrical mating process
