Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional high-availability systems, such as servers, often rely on power supply redundancy but still fall short of achieving 100% availability due to insufficient power distribution and control mechanisms.
Innovation Solution
A bulk power assembly comprising a bulk power distribution subassembly and a bulk power controller and hub subassembly, which provides and monitors bulk DC power from both AC and DC input sources, ensuring reliable distribution and control through modular subassemblies, electronic circuit breakers, and redundant components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If power supply redundancy is implemented, then system availability is improved, but system complexity increases
Solution Approach 1:
The patent combines multiple power supply units into a single bulk power assembly that provides unified AC and DC power distribution. The assembly integrates power conversion, control, and distribution functions into one modular unit, reducing the number of separate components while maintaining redundancy capabilities through internal configuration
Solution Approach 2:
The bulk power assembly performs multiple functions simultaneously: it accepts AC input power, converts it to DC bulk power, provides direct DC input power acceptance, distributes power to multiple loads, and monitors system status. This multi-functionality reduces the need for separate dedicated components for each function
2Power
If bulk DC power distribution is implemented, then power delivery capability is improved, but control complexity increases
Solution Approach 1:
The patent introduces a bulk power controller as an intermediary device that manages the complex control tasks. This controller acts as a mediator between the power distribution network and the loads, handling monitoring, control decisions, and coordination while presenting a simplified interface to the rest of the system
Solution Approach 2:
The system implements comprehensive monitoring and control capabilities with feedback mechanisms that track power distribution status, load conditions, and system health. This feedback enables automatic control adjustments and centralized management, simplifying the control complexity through intelligent automation
