Solution Overview

Problem

In 5G communication systems, portable terminals may unnecessarily increase power consumption and decrease data processing rates due to inaccurate determination of data transmission paths by the base station, leading to transmission through both 4G and 5G paths when only one path is sufficient, and lack of consideration for different data processing rates of respective transmission paths.

Innovation Solution

An electronic device and method that determines data transmission paths based on data size and processing rates, allowing data to be transmitted through only the primary path, thereby reducing power consumption and ensuring timely data receipt by optimizing data processing rates.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If data is transmitted through both 4G and 5G paths simultaneously, then data transmission capacity is improved, but power consumption increases and data processing rate decreases

Engineering Contradiction:

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent implements dynamic path selection by the terminal device, which can flexibly switch between single-path and dual-path transmission modes based on real-time data size and processing rate conditions, rather than using a fixed transmission mode

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes transmission parameters (data size thresholds, processing rate comparisons) to determine the optimal transmission path configuration, transitioning between different transmission modes based on parameter evaluations

Inventive Principle:

Principle #35Parameter changes

2Productivity

If data is transmitted through both 4G and 5G paths simultaneously, then data transmission capacity is improved, but data processing rate decreases

Engineering Contradiction:

Improvedata transmission capacityVSAvoiddata processing rate

Core Design Contradiction:

ProductivityVSSpeed

Solution Approach 1:

The patent uses feedback mechanisms where the terminal device compares data processing rates of different paths and adjusts transmission path selection based on this feedback to maintain optimal data processing performance

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system dynamically adjusts the number of active transmission paths based on real-time performance metrics, switching between single-path and dual-path modes to optimize data processing rate

Inventive Principle:

Principle #15Dynamics

3Extent of automation

If the base station determines transmission paths, then network control is improved, but transmission path determination accuracy decreases

Engineering Contradiction:

Core Design Contradiction:

Extent of automationVSMeasurement precision

Solution Approach 1:

The patent segments the transmission path determination function between the base station (which provides configuration and control) and the terminal device (which performs actual path selection based on local conditions), improving overall determination accuracy

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The terminal device acts as an intermediary that translates base station control intentions into actual path selection decisions, combining network control with local condition awareness

Inventive Principle:

Principle #24Intermediary (Mediator)

4Reliability

If data transmission through multiple paths is implemented, then transmission reliability is improved, but unnecessary power consumption occurs

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The patent applies partial action by using dual-path transmission only when necessary (based on data size and processing rate conditions), rather than always using multiple paths, thus avoiding excessive energy consumption while maintaining reliability when needed

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The system changes the number of active transmission paths as a variable parameter based on transmission requirements, transitioning between single-path and dual-path modes to match actual needs
