Perpendicular Power Module Coupling for Server Rack PDU
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing power distribution systems in server racks face challenges with limited power outlets and tight cable routing spaces, leading to difficulties in accessing power connectors and increased stress on cables due to tight bends.
Innovation Solution
The proposed power system includes a PDU rack with power modules coupled perpendicularly, increasing the number of outlets and providing adequate space for cable access, and power connectors that rotate at least 45 degrees to reduce cable stress and improve installation ease.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If power outlets are mounted directly on the PDU rack, then the number of outlets is limited and cable routing space is restricted, but adding power modules perpendicularly increases device complexity
Solution Approach 1:
The patent transitions from a two-dimensional arrangement where outlets are mounted directly on the PDU rack face to a three-dimensional configuration by attaching power modules perpendicularly to the rack. This vertical extension creates additional outlet capacity without occupying horizontal rack space, effectively resolving the contradiction between increasing outlet quantity and maintaining system simplicity.
2Device complexity
If power outlets are mounted directly on the PDU rack, then the structure is simple, but cable routing space is tight and cable stress increases
Solution Approach 1:
By extending power modules perpendicular to the PDU rack, the patent creates additional spatial dimensions for cable routing. This vertical projection provides adequate clearance for cable insertion and reduces bend radius constraints, improving cable accessibility without requiring complex reconfiguration of the base PDU rack structure.
3Ease of manufacture
If power connectors are fixed in position, then the installation is straightforward, but cable bend radius is constrained and cable stress increases
Solution Approach 1:
The patent introduces rotational mobility to the power connectors, allowing them to pivot and adjust their orientation. This dynamic capability enables optimal cable routing angles and sufficient bend radius during installation, reducing cable stress while maintaining straightforward mounting through the perpendicular module attachment to the PDU rack.
