Solution Overview

Problem

Mobile communication devices in broadcast systems face challenges in optimally receiving data, particularly due to high energy consumption and suboptimal bit-rate management, which affects the quality of service and user experience.

Innovation Solution

A method that determines the amount of data to be received based on the charge state of the battery, allowing for optimal data download by adjusting the amount according to the battery's state, whether it is connected to a charger or not, and considering factors like remaining capacity and power consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If data is received at high data rates in broadcast systems, then the amount of data transmitted increases, but power consumption increases

Engineering Contradiction:
Improveamount of data transmittedVSAvoidpower consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent applies dynamics by making the data reception rate adjustable rather than fixed. The mobile communication device dynamically adapts its data reception rate based on battery charge state, switching between high-rate reception when charged and low-rate reception when battery-powered, thereby optimizing the balance between productivity and energy consumption

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter of data reception rate based on battery charge state. When the device detects it is operating on battery power, it reduces the data reception rate from high to low, directly addressing the contradiction by adjusting system parameters to match operational conditions

Inventive Principle:
Principle #35Parameter changes

2Use of energy by moving object

If data reception rate is reduced to conserve battery power, then power consumption decreases, but quality of service deteriorates

Engineering Contradiction:
Improvepower consumptionVSAvoidquality of service
Core Design Contradiction:
Use of energy by moving objectVSReliability

Solution Approach 1:

The system dynamically adjusts the data reception rate based on real-time battery charge state detection. When charging, it operates at high rate for full quality; when on battery, it switches to low rate for power conservation, making the quality-of-service degradation conditional and reversible rather than permanent

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements periodic monitoring of battery charge state and corresponding adjustment of data reception rate. This periodic switching between high and low reception modes based on power availability allows the system to maintain high quality of service during charging periods while conserving energy during battery-powered periods

Inventive Principle:
Principle #19Periodic action
