Solution Overview

Problem

Portable communication devices with integrated media player functionality face battery power limitations due to ongoing background wireless transmissions, even when in media player mode, leading to frequent charging needs.

Innovation Solution

The device automatically reduces background wireless transmission frequency or ceases certain transmissions when in media player mode to conserve battery power, reverting to normal transmission when exiting media player mode.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If the device maintains normal background wireless transmission while in media player mode, then wireless communication functionality is preserved, but battery power is consumed unnecessarily

Engineering Contradiction:

Improvebattery power consumptionVSAvoidwireless communication functionality

Core Design Contradiction:

Loss of energyVSAdaptability or versatility

Solution Approach 1:

The system dynamically adjusts the extent of background wireless transmission based on the operational mode. When media player mode is detected, the system automatically reduces background wireless transmission activities. This dynamic adaptation allows the device to optimize battery power consumption while maintaining wireless communication functionality when needed, resolving the contradiction between energy efficiency and functional versatility.

Inventive Principle:

Principle #15Dynamics

2Duration of action of moving object

If the device reduces background wireless transmission in media player mode, then battery life is extended, but wireless communication responsiveness may be degraded

Engineering Contradiction:

Improvebattery lifeVSAvoidwireless communication responsiveness

Core Design Contradiction:

Duration of action of moving objectVSReliability

Solution Approach 1:

The system applies different transmission strategies to different wireless communication functions based on their priority. Critical communication functions maintain normal responsiveness even in media player mode, while non-critical background transmissions are reduced. This localized quality adjustment extends battery life while preserving essential wireless communication reliability.

Inventive Principle:

Principle #3Local quality

3Reliability

If the device maintains full wireless transmission activities, then communication reliability is maintained, but battery power is depleted faster

Engineering Contradiction:

Improvecommunication reliabilityVSAvoidbattery power usage

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system implements partial action by selectively reducing only non-critical background wireless transmission activities while maintaining essential communication functions. This approach achieves sufficient communication reliability without the excessive battery power consumption associated with maintaining all transmission activities at full level, thereby resolving the contradiction between reliability and energy usage.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

A method and system for conserving battery power in a portable communication device. When a user puts the device into a media player mode such as by invoking a media player application on the device, the device will automatically reduce the extent to which it engages in background wireless transmissions, such as radio link control messaging, presence update messaging, and so forth, to help conserve battery power. In turn, when the device exits the media player mode, the device may then automatically revert to its normal extent of background wireless transmission.
