Solution Overview

Problem

Portable electronic devices face inefficiencies in battery charging time due to various factors such as initial charge state, charging current, and other conditions, necessitating improvements in charging methodologies.

Innovation Solution

A method is introduced where a portable electronic device detects coupling to a charger and enters a reduced battery use state by applying specific configuration settings to reduce power consumption, such as disabling connectivity and adjusting display settings, to facilitate faster charging.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the portable electronic device operates in standard mode during charging, then the device maintains full functionality and user experience, but the battery charging time is extended due to higher power consumption

Engineering Contradiction:
Improvedevice functionalityVSAvoidcharging time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system dynamically adjusts device configuration based on charging state. When a charger is detected, the device automatically transitions to a reduced battery use state by applying configuration settings that reduce power consumption. This dynamic adaptation allows the device to optimize charging speed while maintaining usability, resolving the contradiction between full functionality and charging time.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes operational parameters by applying configuration settings that modify device behavior during charging. These parameter changes include adjusting display brightness, reducing processor performance, and limiting background activities, which collectively reduce power consumption and accelerate charging without completely sacrificing device functionality.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If the device enters reduced battery use state during charging, then the charging speed increases, but the device functionality and user experience are limited

Engineering Contradiction:
Improvecharging speedVSAvoiddevice functionality
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The system provides dynamic control by allowing users to switch between standard and reduced battery use states based on their immediate needs. The device can transition between these states, enabling users to prioritize either charging speed or functionality depending on the situation, thus resolving the contradiction between charging productivity and operational ease.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The reduced battery use state applies configuration settings that partially limit device functionality rather than completely disabling it. This partial action approach maintains essential functions while reducing overall power consumption, allowing the device to achieve faster charging without entirely sacrificing usability.

Inventive Principle:
Principle #16Partial or excessive action

3Ease of operation

If the device maintains standard operation during charging, then the user experience is preserved, but less charge is stored in the battery for a given charging time

Engineering Contradiction:
Improveuser experienceVSAvoidbattery charge capacity
Core Design Contradiction:
Ease of operationVSQuantity of substance

Solution Approach 1:

The system dynamically adjusts power distribution between device operation and battery charging based on detected charging conditions. By applying configuration settings that reduce power consumption during charging, more electrical energy is directed to battery storage, increasing the quantity of charge accumulated while maintaining acceptable user experience through selective functionality preservation.

Inventive Principle:
Principle #15Dynamics

AI summary

A method of controlling a portable electronic device that has a battery. The method includes, in response to detecting coupling of the portable electronic device to a charger for charging the battery of the portable electronic device, determining if a condition is met to enter a reduced battery use state, and in response to determining that the condition to enter the reduced battery use state is met, identifying a configuration setting of the portable electronic device in the reduced battery use state, and entering the reduced battery use state by applying the configuration setting to adjust a configuration of the portable electronic device.
