Power Storage Adapter Thermal Management via Dynamic Power Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power storage adapters fail to effectively manage temperature changes, leading to potential overheating and thermal shutdown during power delivery to portable information handling systems, as they do not account for temperature and rate of temperature change in their power supply strategies.
Innovation Solution
A power storage adapter with a controller that measures temperature and rate of temperature change, adjusting the power delivery by switching from a first electrical power to a second, lower power level when thresholds are exceeded, and communicating this change to the connected device via a USB power delivery protocol, ensuring safe operation and preventing overheating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the power storage adapter supplies high electrical power to electronic devices, then the power delivery capability is improved, but the temperature increases and thermal shutdown risk worsens
Solution Approach 1:
The power storage adapter dynamically adjusts the power delivery level based on real-time temperature monitoring. When temperature exceeds thresholds, the system transitions from high power mode to reduced power mode, creating a dynamic adaptation mechanism that resolves the contradiction between maintaining high power delivery and preventing overheating
Solution Approach 2:
The system implements a feedback loop where temperature sensors continuously monitor thermal conditions and feed this information back to the power management controller. This feedback mechanism enables the system to automatically adjust power delivery levels in response to temperature changes, resolving the contradiction between power output and thermal management
2Productivity
If the power storage adapter increases power delivery to meet device demands, then the productivity is improved, but the reliability deteriorates due to thermal shutdown risk
Solution Approach 1:
The system performs preliminary temperature assessment before initiating high power delivery and continuously monitors temperature throughout operation. By detecting temperature trends in advance, the system can proactively reduce power levels before thermal shutdown conditions develop, maintaining reliability while maximizing productivity
Solution Approach 2:
The adapter employs dynamic power adjustment that transitions between different power delivery states based on thermal conditions. This dynamic behavior allows the system to maintain high productivity when safe and automatically adjust to preserve reliability when thermal limits are approached, resolving the contradiction between these two parameters
3Ease of operation
If the power storage adapter maintains high power delivery without temperature monitoring, then the ease of operation is improved, but the harmful factors worsen due to overheating
Solution Approach 1:
The power storage adapter incorporates self-service thermal management through integrated temperature sensors and automated power adjustment logic. The system independently monitors its own thermal state and adjusts power delivery without user intervention, maintaining ease of operation while preventing overheating through self-regulation
Solution Approach 2:
The system uses internal temperature feedback to automatically control power delivery levels. Temperature sensors provide continuous feedback to the power management controller, which autonomously adjusts power output to prevent overheating, resolving the contradiction between operational simplicity and thermal safety

AI summary
A power storage adapter may use a method for power delivery based on temperature and other factors. In particular, when electrical power is being supplied to a portable information handling system, a temperature of the power storage adapter may increase. Power storage adapter may reduce the electrical power being supplied to the portable information handling system based on the temperature to prevent the power storage adapter from potentially overheating.
