Flexible Power Allocation for Computer Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current power supply arrangements in computer systems are rigid, leading to inefficiencies due to unused or underused power rail capacity, as there is no flexible sharing of power among rails, even those of the same voltage, resulting in suboptimal power utilization during different operational configurations.
Innovation Solution
A flexible power allocation system that allows power sharing and redistribution across multiple rails, including those of similar or dissimilar voltage, using a 'shopping cart' approach based on subsystem or component power capabilities, where current can be reallocated from one rail to another in response to changing power demands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If power supply arrangements are rigidly configured with dedicated rails for specific functions, then reliability and stability are improved, but power utilization efficiency deteriorates due to unused or underused power rail capacity
Solution Approach 1:
The patent implements dynamic power allocation where power rails can be reassigned to different components based on real-time power demands. The system transitions from static dedicated rail assignments to dynamic flexible assignments, allowing power capacity to be optimized for current operational needs while maintaining reliable power delivery through controlled reassignment.
Solution Approach 2:
The system changes the parameter of power rail assignment from fixed to variable. By monitoring power demands and reassigning rails when demands change, the system optimizes power utilization efficiency without compromising the stability of power delivery to active components.
2Ease of operation
If power rails are strictly dedicated to specific functions, then ease of control is improved, but adaptability deteriorates as the system cannot flexibly share power among rails during different operational configurations
Solution Approach 1:
The patent introduces dynamic reassignment of power rails based on detected power demands. The system maintains ease of control through automated monitoring and reassignment mechanisms, while simultaneously improving adaptability by allowing power capacity to be reallocated to match varying operational configurations and component needs.
Solution Approach 2:
The system employs feedback mechanisms to monitor power demands of components and automatically reassign power rails in response to detected changes. This feedback loop enables the system to adapt to different operational configurations while maintaining controlled and systematic power management through automated decision-making.
3Manufacturing precision
If power supply design is very specific with regard to allowable current in different rails, then manufacturing precision is improved, but power utilization efficiency deteriorates due to inability to optimize power distribution
Solution Approach 1:
The patent changes the parameter of power rail assignment from static to dynamic. By maintaining precise current specifications for each rail while allowing flexible reassignment of which components receive power from which rails, the system preserves manufacturing precision requirements while dramatically improving power utilization efficiency through optimized distribution based on actual power demands.

AI summary
Arrangements which provide a degree of flexible power allocation among multiple power rails in computer systems, in a manner to permit the sharing and exchange of power across multiple rails. The rails involved in such sharing could be of similar or dissimilar voltage. By way of an advantageous refinement, a “shopping cart” approach for system configuration is permitted, based on subsystem or component power capability.
