Power Storage Adapter Dynamic Contract Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power storage adapters face challenges in efficiently managing power delivery contracts to multiple portable information handling systems, where one system may draw less power than contracted, limiting the ability to supply sufficient power to another system that requires it.
Innovation Solution
A power storage adapter with a controller that detects when one information handling system is drawing less power than contracted, resets the contract to supply a lower power level, and reallocates power to establish a new contract that meets the needs of another system, using USB power delivery protocols and multiple ports like USB Type-C.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a power storage adapter establishes a power delivery contract to supply a contracted power level to one information handling system, then the system can operate with guaranteed power supply, but the adapter cannot supply sufficient power to another system that requires it when the first system draws less power than contracted
Solution Approach 1:
The patent implements dynamic power delivery contract management by allowing the adapter to reset and reestablish power contracts based on real-time power draw monitoring. When a system draws less power than contracted, the adapter can terminate the original contract and establish a new contract with adjusted power levels, enabling flexible reallocation of power resources while maintaining reliability for systems that actually need the guaranteed power supply
Solution Approach 2:
The adapter continuously monitors the actual power draw of connected systems and uses this feedback to make intelligent decisions about power contract management. By detecting when a system draws less power than contracted, the adapter can trigger contract reset procedures to free up power capacity for other systems, creating a closed-loop control system that optimizes power distribution based on actual demand
2Stability of the object's composition
If the power storage adapter maintains an existing power delivery contract, then the first information handling system has stable power supply, but the adapter cannot establish a new power delivery contract to supply sufficient power to a second information handling system
Solution Approach 1:
The patent implements periodic power contract review and reset mechanisms. The adapter periodically monitors power draw and can trigger contract reset operations at appropriate intervals. This periodic action allows the system to maintain stability during normal operation while periodically reevaluating and adjusting power contracts to optimize overall power delivery efficiency and enable service to additional systems
3Reliability
If the power storage adapter supplies power according to the first power delivery contract, then the first information handling system receives the contracted power level, but power is wasted when the system draws less power than contracted
Solution Approach 1:
The patent dynamically changes power delivery parameters by resetting and reestablishing power contracts with adjusted power levels. When monitoring detects that a system draws less power than contracted, the adapter modifies the power contract parameters to match actual demand, thereby eliminating power waste while maintaining reliable power delivery commitment for systems that actually require the contracted power levels

AI summary
A power storage adapter may use a power delivery contract establishment method when supplying electrical power to portable information handling systems when the amount of electrical power the power storage adapter is able to supply is less that the amount the portable information handling systems require. In particular, the power storage adapter may avoid supplying electrical power to one of the portable information handling systems that has gotten what is needs and may switch to supplying more electrical power to one of the other portable information handling systems that has not received what it requires.
