Solution Overview

Problem

Existing systems fail to dynamically adjust eSIM configurations in response to fluctuations in Wi-Fi internet bandwidth, leading to suboptimal performance of internet-based activities on mobile devices.

Innovation Solution

A system that continuously evaluates internet-based activity performance on a mobile device using Wi-Fi, identifying deviations or predicted reductions in bandwidth, and proactively reconfigures the eSIM to maintain performance by selecting appropriate mobile network providers or data plans.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If eSIM configuration is dynamically adjusted based on Wi-Fi bandwidth, then internet performance consistency is improved, but system complexity increases

Engineering Contradiction:
Improveinternet performance consistencyVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The eSIM configuration is made dynamic by continuously monitoring Wi-Fi bandwidth metrics and automatically adjusting eSIM parameters (such as APN settings, authentication methods, or network selection) in response to detected bandwidth deviations. This allows the system to adapt to changing network conditions and maintain consistent internet performance without manual intervention.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system implements a feedback loop where Wi-Fi bandwidth performance is continuously evaluated, compared against expected thresholds, and used to trigger eSIM reconfiguration when deviations are detected. This closed-loop control ensures that eSIM settings are optimized based on real-time network conditions, resolving the contradiction between performance consistency and system complexity.

Inventive Principle:
Principle #23Feedback

2Reliability

If eSIM reconfiguration is performed to compensate for bandwidth deviation, then internet performance is maintained, but processing time increases

Engineering Contradiction:
Improveinternet performanceVSAvoidprocessing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by pre-evaluating multiple eSIM configuration options and preparing optimized settings before bandwidth deviations occur. When bandwidth issues are detected, the system can quickly switch to pre-prepared configurations rather than performing complex analysis and reconfiguration in real-time, thus maintaining internet performance while minimizing processing time delays.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If continuous evaluation of internet activity performance is implemented, then connectivity optimization is improved, but energy consumption increases

Engineering Contradiction:
Improveconnectivity optimizationVSAvoidenergy consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

Instead of continuous real-time evaluation, the system implements periodic sampling of internet activity performance metrics at predetermined intervals. This approach maintains connectivity optimization by detecting significant bandwidth deviations while consuming less energy by avoiding constant monitoring and processing, thus resolving the contradiction between productivity and energy consumption.

Inventive Principle:
Principle #19Periodic action
