Solution Overview

Problem

Existing power supply mechanisms in information handling systems are expensive and complex, struggling to efficiently manage and monitor Point-of-Load converters (POL converters) across varying voltage and current levels, leading to suboptimal performance and increased power dissipation.

Innovation Solution

A power supply management system comprising a controller communicatively coupled with POL converters through multiple communication paths, including a shared memory for data exchange, which optimizes power delivery by reducing power requirements based on system needs, utilizing signals to adjust voltage and current levels, and employing wireless interfaces for efficient control and monitoring.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a central power supply controller is used to monitor and control POL converters, then power delivery control is improved, but device complexity and cost increase

Engineering Contradiction:
Improvepower delivery controlVSAvoidcontroller complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements self-service by enabling POL converters to autonomously manage their own power delivery and monitoring without requiring a complex central controller. Each POL converter independently handles voltage conversion, load monitoring, and power management, thereby reducing overall system complexity while maintaining reliable power delivery control.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent extracts the power control functionality from a centralized controller and distributes it to individual POL converters. By removing the complex central controller and giving each POL converter independent control capabilities, the system achieves simplified architecture while maintaining effective power delivery management.

Inventive Principle:
Principle #2Taking out (Extraction)

2Loss of energy

If POL converters operate at fixed voltage and current levels, then device operation is simplified, but power dissipation increases

Engineering Contradiction:
Improvepower dissipationVSAvoidoperation flexibility
Core Design Contradiction:
Loss of energyVSEase of operation

Solution Approach 1:

The patent implements dynamics by enabling POL converters to dynamically adjust their operating voltage and current levels based on real-time load requirements. Instead of fixed operation, the system continuously adapts power delivery parameters to match actual demands, thereby reducing power dissipation while maintaining operational flexibility through automated adjustment.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent applies parameter changes by allowing POL converters to modify their voltage and current operating parameters in response to changing load conditions. The system changes power delivery parameters dynamically rather than maintaining fixed values, which reduces energy loss while preserving the ability to adapt to various operational requirements through automated parameter adjustment.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If multiple communication paths are used for controller-POL converter interaction, then control efficiency is improved, but device complexity increases

Engineering Contradiction:
Improvecontrol efficiencyVSAvoidcommunication path complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent applies universality by implementing a multi-functional communication interface that handles both control signals and monitoring data through a single integrated path. The communication system serves multiple purposes including power delivery control, status monitoring, and configuration, thereby improving control efficiency without proportionally increasing system complexity through consolidation of functions.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

System and methods for controlling power delivery to system components are disclosed. A controller is communicatively coupled to a point-of-load converter through a first communication path and a shared memory is communicatively coupled to the point-of-load converter through a second communication path. A third communication path communicatively couples the controller and the shared memory. Control data is communicated from the controller to the point-of-load converter through the first communication path and measurement data is written from the point-of-load converter to the shared memory through the second communication path. The controller is operable to read the measurement data from the shared memory through the third communication path.
