Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In data centers, maintenance of power electronics in racks can disrupt power supply to compute devices, leading to reduced operational efficiency and financial losses due to downtime.
Innovation Solution
A modular edge power system with removably inserted edge modules and redundant power buses allows for quick replacement of failed modules without interrupting power to other devices, utilizing SNMP agents for remote monitoring and maintenance reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If power electronics are integrated into each rack, then power delivery to compute devices is ensured, but maintenance of power electronics causes interruption of power to all compute devices in the rack
Solution Approach 1:
The power system is divided into multiple independent power modules, each capable of providing power to compute devices through separate power buses. When maintenance is needed on one module, other modules continue operating, preventing complete power interruption to the rack.
Solution Approach 2:
Each power module is designed with independent functionality and local power delivery capability through dedicated power buses. This allows localized maintenance of individual modules without affecting the operational status of other modules and their associated compute devices.
2Reliability
If power electronics are integrated into each rack, then power delivery is maintained, but replacement of failed power electronics requires significant downtime
Solution Approach 1:
The power system is segmented into independent, modular units that can be individually accessed and replaced. Each module can be removed and installed without disrupting the entire rack's power infrastructure, enabling quick field replacement while maintaining power delivery through redundant modules.
Solution Approach 2:
The modular design allows dynamic reconfiguration of power delivery paths. When a module is replaced, the system dynamically redistributes power loads across remaining operational modules, facilitating easy maintenance while preserving continuous power delivery capability.
3Loss of time
If redundant power modules are implemented, then maintenance can be performed without interrupting power, but device complexity increases
Solution Approach 1:
The system uses segmented power modules with standardized interfaces and configurations. This segmentation enables redundancy while controlling complexity through modular design principles, where each module is a self-contained unit that can be independently managed, monitored, and replaced.
Solution Approach 2:
The power modules are designed with universal functionality and standardized interfaces, allowing any module to replace any other module in the system. This multi-functionality reduces the need for specialized components and simplifies the overall system architecture despite having multiple modules.

AI summary
A modular edge power system is provided. The modular edge power system includes a housing and multiple edge modules. Each edge module is adapted to be removably inserted into the housing and provide, through a corresponding bus and with one or more power equipment submodules, power to one or more compute devices in a rack. Each bus is adapted to provide sufficient power to enable operation of every compute device in the rack.
