Solution Overview

Problem

Current mobile devices do not consider scenario factors when selecting a network connection, leading to inefficient power consumption in scenarios like high-speed trains, elevators, or basements.

Innovation Solution

Implementing a system that allows slave mobile devices to monitor sensor inputs and high-layer configurations, generating a scenario indication based on a scenario matrix, and dynamically switching between wide area wireless networks and local connection networks based on detected scenarios and lower-layer reports.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If slave devices maintain cellular connection for broad coverage, then network reachability is improved, but power consumption increases in specific scenarios

Engineering Contradiction:
Improvenetwork reachabilityVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system dynamically switches between cellular and local connection networks based on detected scenarios. The slave device monitors sensor inputs (accelerometer, barometer, GNSS) and scenario matrices to determine when to switch from cellular to local network mode, making the network connection adaptive rather than static, thus reducing power consumption in scenarios like high-speed trains or elevators while maintaining broad coverage capability when needed.

Inventive Principle:
Principle #15Dynamics

2Use of energy by moving object

If slave devices use local connection networks, then power consumption is reduced, but network coverage is limited

Engineering Contradiction:
Improvepower consumptionVSAvoidnetwork coverage
Core Design Contradiction:
Use of energy by moving objectVSReliability

Solution Approach 1:

The master device serves as an intermediary that bridges the local connection network to the wide area network. The slave device connects locally to the master device, which in turn maintains cellular connectivity, allowing the slave to benefit from reduced power consumption while the master provides broad network coverage, effectively combining both advantages.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If network switching is based on signal strength, then connection quality is maintained, but scenario-specific power optimization is lost

Engineering Contradiction:
Improveconnection qualityVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system changes the decision parameter for network switching from purely signal strength-based metrics to scenario-based detection using sensor inputs and scenario matrices. This allows the system to identify specific scenarios (high-speed train, elevator, basement) and make informed network switching decisions that optimize power consumption while maintaining adequate connection quality for each scenario.

Inventive Principle:
Principle #35Parameter changes
