Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power management systems in data centers face issues with communication disruption when local management units malfunction, leading to increased maintenance costs and time-consuming processes due to the lack of real-time power data acquisition and inefficient data transmission paths.
Innovation Solution
A power distribution unit with a hot-swappable module that allows for easy assembly and disassembly, enabling communication with remote power management units and adjacent distribution units, reducing the need for local management units and simplifying maintenance by using a master-slave configuration with hot-swappable intelligent modules for data transmission and power control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If local management units are used for communication between power distribution units and remote power management units, then power distribution control is achieved, but communication disruption occurs when local management units malfunction and maintenance becomes time-consuming
Solution Approach 1:
The patent removes local management units from the system architecture. Power distribution units directly communicate with remote power management units through the network, eliminating the intermediate local management units that caused communication disruptions and maintenance issues.
Solution Approach 2:
Power distribution units are equipped with both power distribution functionality and communication functionality. Each power distribution unit can directly communicate with the remote power management unit, making the system more robust and eliminating single points of failure.
2Ease of repair
If conventional power distribution units are used without hot-swappable modules, then system stability is maintained, but maintenance and management become costly and time-consuming
Solution Approach 1:
The power distribution unit is divided into modular components, particularly the communication module which can be hot-swapped. This segmentation allows the communication module to be replaced independently without affecting the power distribution functionality.
Solution Approach 2:
The system implements hot-swappable modules that can be dynamically added or removed without powering down the system. This dynamic capability enables maintenance personnel to replace communication modules quickly while the power distribution unit remains operational.
3Productivity
If multiple local management units are deployed for managing power distribution units, then comprehensive power management is achieved, but system complexity increases and maintenance costs rise
Solution Approach 1:
Local management units are completely removed from the system. The patent simplifies the architecture by having power distribution units communicate directly with remote power management units, eliminating the need for multiple intermediate management layers.
Solution Approach 2:
The communication and power distribution functions are merged into a single integrated unit. Power distribution units directly interface with remote power management units, consolidating the system architecture and reducing the number of separate components.

AI summary
A power distribution unit includes a power input terminal, a main body, plural power-providing units, a coupling module and a hot-swappable module. The plural power-providing units are installed on the main body and electrically connected with plural electronic devices to provide electric power to the plural electronic devices. The coupling module is embedded within the main body. The hot-swappable module is detachably connected with the coupling module. When the hot-swappable module is connected with and disposed within the coupling module, the power distribution unit is in communication with a remote power management unit and/or an adjacent power distribution unit.
