Solution Overview
Problem
In data centers, especially those with edge architecture, the complex cable arrangements for power distribution to compute devices in racks are inefficient and difficult to manage, requiring a more modular and efficient solution for power delivery.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional cable arrangements are used to connect compute devices to DC distribution panels, then power distribution can be achieved, but the cable arrangements become complicated and difficult to manage
Solution Approach 1:
The power distribution system is segmented into modular Power Distribution Units (PDUs) that can be independently installed and managed. Each PDU serves a specific rack or group of compute devices, breaking down the monolithic DC distribution panel into smaller, more manageable segments. This segmentation reduces cable complexity by localizing power distribution functions and enabling organized, scalable deployments.
2Ease of manufacture
If DC distribution panels are located in rack bays with complicated cable arrangements, then power can be delivered to compute devices, but cabinet space is wasted and installation becomes difficult
Solution Approach 1:
The power distribution function is extracted from the compute device racks and consolidated into separate, dedicated Power Distribution Units. These PDUs are positioned in optimal locations within the cabinet structure, freeing up rack space for revenue-generating equipment while simplifying installation through standardized mounting interfaces and pre-organized cable pathways.
3Ease of operation
If modular pluggable PDUs are implemented, then installation and maintenance become easier with tool-free operation, but the system requires specialized interfaces and connectors
Solution Approach 1:
The pluggable PDU interfaces are designed with self-aligning and self-latching mechanisms that enable tool-free installation and maintenance. The connectors incorporate guide pins, alignment features, and automatic engagement systems that allow technicians to install or replace PDUs by hand without requiring specialized tools or complex alignment procedures, thereby simplifying operations while managing interface complexity through intuitive design.

AI summary
A modular edge power system is provided. The modular edge power system includes a housing (12) having a rack (20) adapted to mount compute devices (114) and a direct current power bus (80) within the housing. Multiple power distribution units (100) are adapted to be removably coupled to the direct current power bus at a position within the housing and outside of the rack. Each power distribution unit is configured to distribute electrical power received from the direct current power bus to one or more compute devices mounted in the rack. Each power distribution unit may convert the electrical power from a first power level to a second power level.
