Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voltage regulator (VR) controllers in Information Handling Systems (IHS) are inflexible, requiring multiple part numbers for different CPU power requirements and configurations, leading to inefficiencies in production and future CPU upgrades, as they are typically configured during manufacturing and cannot be dynamically adjusted.
Innovation Solution
A configurable VR controller that identifies the number of phases and selects appropriate configuration files from pre-stored options in Non-Volatile Memory (NVM) or a Baseband Management Controller (BMC), allowing for dynamic assembly of configuration files based on detected phases and CPU power requirements, enabling a single part number for various configurations and supporting CPU upgrades.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple part numbers are used for different CPU power requirements, then VR configuration flexibility is improved, but device complexity and production efficiency deteriorate
Solution Approach 1:
The patent implements a universal VR controller design that can adapt to multiple CPU power requirements through a single part number. The controller includes configurable parameters such as number of phases, current per phase, and power module characteristics that can be dynamically adjusted via configuration files stored in NVM or provided by BMC, eliminating the need for multiple specialized part numbers while maintaining compatibility with different CPU power requirements.
Solution Approach 2:
The patent introduces dynamic configurability to the VR controller through runtime parameter adjustment. Configuration files containing phase count, current settings, and power module parameters can be loaded and modified during system operation based on detected CPU requirements, allowing the hardware to dynamically adapt its behavior without physical reconfiguration or manual intervention.
2Manufacturing precision
If manual reconfiguration is required for CPU upgrades, then manufacturing precision is improved, but ease of operation and productivity deteriorate
Solution Approach 1:
The patent implements self-service reconfiguration capability where the VR controller automatically detects CPU power requirements and configures appropriate parameters without manual intervention. The system uses configuration files that can be automatically selected and loaded based on detected CPU characteristics, enabling plug-and-play CPU upgrades while maintaining precise configuration accuracy.
Solution Approach 2:
The patent incorporates feedback mechanisms where the VR controller continuously monitors system state and CPU requirements, then automatically adjusts configuration parameters accordingly. This closed-loop approach ensures that configuration accuracy is maintained while eliminating manual reconfiguration steps, as the system self-corrects based on detected conditions.
3Ease of manufacture
If configuration files are pre-stored in NVM, then ease of manufacture is improved, but device complexity increases
Solution Approach 1:
The patent implements preliminary configuration by pre-storing multiple configuration files in NVM during manufacturing, each representing different CPU power requirements. This allows the VR controller to be produced with all necessary configuration data already embedded, simplifying the manufacturing process and eliminating the need for post-assembly configuration steps, while the added NVM storage requirement represents a manageable increase in device complexity.
