Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable information handling systems face inefficiencies in power management when drawing low electrical power, leading to reduced battery life and increased energy losses due to the continuous supply of power by power storage adapters, even when the system is in a low power state.
Innovation Solution
A power storage adapter that dynamically adjusts power delivery based on the state of charge of the internal battery and the low power threshold, terminating power supply when below a certain threshold and resuming when the battery state falls below a recharging state, thereby optimizing charging efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the power storage adapter continuously supplies electrical power to the portable information handling system, then the system remains powered and operational, but energy losses increase and battery life decreases when the system is in a low power state
Solution Approach 1:
The power storage adapter dynamically adjusts its power supply behavior based on the detected power state of the connected system. When low power draw is detected (indicating a low power state), the adapter discontinues power supply. When normal power draw is detected, the adapter resumes power supply. This dynamic adaptation resolves the contradiction by making the system reliable only when necessary while minimizing energy losses during low power states.
Solution Approach 2:
The adapter implements a feedback mechanism by monitoring the power draw from the connected system and adjusting its power supply accordingly. The controller detects whether the system is in a low power state or normal operational state, and uses this feedback to决定是否 to supply power. This feedback loop enables the adapter to optimize energy efficiency while maintaining system reliability when needed.
2Quantity of substance
If the power storage adapter supplies power during low power states, then the internal battery remains charged, but charging efficiency decreases due to continuous low-level power delivery
Solution Approach 1:
Instead of continuous low-level power delivery, the adapter implements periodic charging by discontinuing power supply during low power states and resuming when the system enters normal operational state or when battery level falls below recharging threshold. This periodic action pattern improves charging efficiency by concentrating power delivery into more efficient, higher-level charging sessions rather than continuous inefficient low-level delivery.
Solution Approach 2:
The adapter changes the power delivery parameters dynamically - switching between discontinuing power supply and resuming power supply based on system state and battery charge level. When the internal battery charge level falls below the recharging threshold (e.g., 10%), the adapter changes from a discontinuous power mode to a continuous power mode, optimizing charging efficiency while maintaining adequate battery charge levels.
3Productivity
If the power storage adapter monitors and dynamically adjusts power supply based on system state and battery charge level, then charging efficiency improves, but device complexity increases
Solution Approach 1:
The power storage adapter performs self-service by autonomously monitoring its own battery charge level and the power draw from the connected system, then automatically adjusting its power supply behavior without user intervention. The controller independently determines when to discontinue or resume power supply based on pre-programmed logic regarding battery thresholds and power state detection. This self-service capability achieves efficient power management while minimizing the need for complex external control systems.

AI summary
A power storage adapter may use a high efficiency charging method when supplying electrical power to a portable information handling system when the power storage adapter is not connected to AC line power. In particular, when the portable information handling system draws the electrical power below a low load threshold, such as during a low power state, the power storage adapter may avoid supplying electrical power. When an internal battery of the portable information handling system has an SOC less than a recharging state of charge for the internally battery, the power storage adapter may resume supplying power to the portable information handling system.
