Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a single MNO network profile is used for emergency communication, then the device complexity is low, but the reliability deteriorates due to network outages and connectivity issues

Engineering Contradiction:
Improvecommunication reliabilityVSAvoidSIM card structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The SIM card is segmented into multiple independent MNO network profiles (home network profile and roaming network profiles), allowing the system to switch between different network operators. This segmentation enables the device to maintain communication reliability by selecting an available network profile when the primary network experiences outages or connectivity issues.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The SIM card is designed with multi-functionality by incorporating multiple MNO network profiles within a single card. This universal design allows the SIM card to operate across different mobile network operators, both domestic and international, ensuring that emergency communication functionality is maintained regardless of which network the device is connected to.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Loss of time

If manual network switching is implemented, then the device complexity is low, but the loss of time increases due to human intervention delays in emergency situations

Engineering Contradiction:
Improvenetwork switching timeVSAvoidnetwork switching automation
Core Design Contradiction:
Loss of timeVSExtent of automation

Solution Approach 1:

The system implements self-service by automatically detecting network connectivity status and autonomously switching between home and roaming network profiles without requiring manual user intervention. The SIM card and device work together to monitor network availability and perform profile switching independently, ensuring immediate response to network outages and minimizing time loss in emergency communication.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If multiple MNO profiles are stored in the SIM card, then the adaptability improves for international roaming, but the device complexity increases
