Solution Overview
Problem
Existing power systems for information handling systems are bulky, require excessive cabling, and are difficult to scale or modify to accommodate varying power demands and interruptions, necessitating a compact and scalable solution for power management.
Innovation Solution
A scalable power and management module (PMM) is introduced, comprising a chassis with slideable insertion into a rack, featuring multiple power supply units and a management controller that provides scalable power distribution and rack-level management, enabling seamless power control and management across IT gear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If traditional power systems are used in information handling systems, then power supply and control functions are provided, but the system takes up large amounts of space and requires excessive numbers of cables
Solution Approach 1:
The patent combines multiple power supply units and management functions into a single integrated power and management module (PMM). This consolidation merges previously separate power supply components and cabling systems into one unified device, reducing the overall space required and eliminating excessive cabling while maintaining full power supply and control functionality
Solution Approach 2:
The PMM is designed as a universal module that can provide power distribution and management functions to multiple different IT gear types within a rack. The module serves multiple functions including power supply, power management, and system control through a single device, replacing the need for multiple specialized components and their associated cabling
2Adaptability or versatility
If traditional power systems are used in information handling systems, then power distribution is provided, but the system is difficult to modify if more or less power is required
Solution Approach 1:
The power system is segmented into modular PMM units that can be independently configured and scaled. Each PMM is a self-contained module that can be added, removed, or reconfigured based on power requirements. This segmentation allows the system to be easily modified by simply adding or removing modules rather than reconfiguring an integrated system
Solution Approach 2:
The PMM system is designed to be dynamic and adaptable, allowing the number and configuration of power supply units within each module to be adjusted based on changing power demands. The modular architecture enables the system to evolve from small to large configurations without requiring complete system replacement or complex reconfiguration
3Power
If multiple power supply units are provided to meet varying power demands, then power requirements are satisfied, but the system becomes bulky and complex
Solution Approach 1:
Multiple power supply units are nested within a single PMM chassis, with multiple units housed in one compact module. This nesting approach allows multiple power supplies to be integrated in a space-efficient manner, providing high power capacity without proportionally increasing the space occupied, as the nested structure shares common housing and management infrastructure

AI summary
A scalable power and management module (PMM) includes a chassis configured to be slideably inserted into a power and management bay within a rack. The PMM provides scalable power distribution and rack-level management functions that are shared by several information technology (IT) gear. Several power supply units (PSUs) are mounted in the chassis. The number of PSUs is scalable based on the number of IT gear. A management controller is mounted in the chassis to provide rack-level management of the IT gear and at least one associated block controller within the rack. A power controller is mounted in the chassis and is communicatively coupled to the PSUs and the management controller. The power controller controls power functions of the PMM.
