Solution Overview

Problem

Mobile electronic devices face increased current consumption and heating issues during prolonged data transmission, which can lead to battery drain and overheating, especially during live broadcasting services.

Innovation Solution

A method for controlling content transmission by adjusting the transmit power function based on context information such as heating information and network traffic, involving the use of a portable electronic device with a communication interface, memory, and processor to determine optimal transmission times and power levels, thereby reducing current consumption and heat generation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If data transmission is performed for a longer time to complete live broadcasting, then the broadcasting service quality is improved, but current consumption increases and battery capacity is depleted faster

Engineering Contradiction:
Improvetransmission timeVSAvoidcurrent consumption
Core Design Contradiction:
Duration of action of moving objectVSUse of energy by moving object

Solution Approach 1:

The patent applies dynamics by making the transmit power function adjustable and changeable based on real-time conditions. The processor dynamically switches between first and second transmit power functions according to battery capacity thresholds, allowing the system to adapt its power consumption characteristics to current battery status while maintaining transmission functionality.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the transmit power parameter based on battery capacity conditions. When battery capacity falls below a threshold, the system transitions from a first transmit power function to a second transmit power function, effectively changing the power transmission parameters to reduce energy consumption and extend operation time.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If transmit power is increased to improve transmission quality, then data transmission reliability is improved, but heating of the electronic device increases

Engineering Contradiction:
Improvetransmission reliabilityVSAvoiddevice temperature
Core Design Contradiction:
ReliabilityVSTemperature

Solution Approach 1:

The system dynamically adjusts transmit power based on battery capacity and thermal conditions. By switching between different transmit power functions, the system can reduce power transmission when heating occurs, thereby lowering device temperature while maintaining transmission reliability through adaptive power management.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements feedback mechanisms by monitoring battery capacity and thermal conditions, then adjusting transmit power accordingly. The processor continuously evaluates system state and modifies transmission parameters to prevent overheating while maintaining acceptable transmission quality, creating a closed-loop control system.

Inventive Principle:
Principle #23Feedback

3Productivity

If continuous data transmission is performed, then live broadcasting service quality is maintained, but battery capacity is depleted faster

Engineering Contradiction:
Improvetransmission efficiencyVSAvoidbattery capacity consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent changes transmission parameters by switching between different transmit power functions based on battery capacity thresholds. This allows the system to optimize the balance between transmission efficiency and energy consumption, extending battery life while maintaining broadcasting service.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system applies partial action by using reduced transmit power (second function) when battery capacity is low, accepting somewhat reduced transmission performance in exchange for extended operation time. This trade-off allows the broadcasting service to continue longer overall.

Inventive Principle:
Principle #16Partial or excessive action
