Modular Chassis Power Regulation via Dynamic Limit Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional modular chassis systems face challenges in power management and regulation, particularly in configuring parameters to prevent excessive power consumption, which is often manual, time-consuming, and prone to errors, especially in enterprise environments with multiple chassis and information handling systems.
Innovation Solution
A chassis with a power supply and controller that dynamically adjusts module power limits based on a threshold power level, decreasing consumption when power exceeds the threshold and increasing it when power is sufficient, ensuring efficient power distribution across modules.

Engineering Contradiction Analysis
1Productivity
If manual power configuration is used in traditional modular chassis systems, then setup flexibility is maintained, but time consumption and error rates increase significantly
Solution Approach 1:
The system performs self-configuration by automatically detecting inserted modules, identifying their power requirements, and configuring power parameters without manual intervention. The chassis controller autonomously manages power allocation based on module characteristics and current power consumption levels.
Solution Approach 2:
Power parameters and module profiles are pre-configured in the system database before modules are inserted. When modules are added to the chassis, the system retrieves pre-prepared configuration data and applies it automatically, eliminating the need for real-time manual configuration.
2Use of energy by moving object
If dynamic power adjustment is implemented, then power efficiency improves, but system complexity increases
Solution Approach 1:
The system continuously monitors power consumption from each module and compares it against allocated power limits. When power thresholds are approached or exceeded, the system automatically adjusts power allocation and notifies relevant modules, creating a closed-loop feedback mechanism for power management.
Solution Approach 2:
Power allocation is made dynamic rather than static, allowing the system to adjust power limits in real-time based on current consumption patterns, module priorities, and available power capacity. This enables flexible power management that adapts to changing system conditions.
3Reliability
If power limits are strictly enforced per module, then power overconsumption is prevented, but system adaptability decreases
Solution Approach 1:
The power management system serves multiple functions: it enforces individual module power limits to prevent overconsumption, dynamically reallocates power among modules based on priorities and needs, and provides overall system power optimization. This multi-functional approach maintains reliability while enabling flexibility.
Solution Approach 2:
The system changes power parameters dynamically based on system conditions, module types, and consumption patterns. Power limits are not fixed but can be adjusted within defined ranges, allowing the system to maintain reliability constraints while adapting to different operational scenarios and module requirements.

AI summary
A controller may be communicatively coupled to a power supply and may be configured to receive a status signal indicative of whether a level of power delivered by the power supply exceeds a threshold power level. The controller may also be configured to, in response to the status signal indicating the level of power delivered by the power supply exceeds the threshold power level, cause a module power limit of at least one of a plurality of modules disposed in a chassis to decrease, wherein the module power limit of a module defines a maximum amount of power the module may consume from the power supply. The controller may also be configured to, in response to the status signal indicating the level of power delivered by the power supply does not exceed the threshold power level, cause the module power limit to increase.
