Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual testing of multimode system selection is performed, then testing accuracy can be ensured, but testing time becomes excessively long

Engineering Contradiction:

Improvetesting accuracyVSAvoidtesting time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent uses a parser to automatically extract and copy system selection information (PLMN, PRL, MLPL, MSPL) from the UICC card, creating a digital representation that can be processed and tested automatically without manual intervention, thus maintaining accuracy while reducing time

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent replaces manual mechanical testing processes with an automated computer-based system that parses UICC data, generates test scenarios programmatically, and executes tests automatically, substituting human operators with automated software agents

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If comprehensive multimode system selection testing is performed, then system reliability is improved, but device complexity increases

Engineering Contradiction:

Improvesystem reliabilityVSAvoidtesting system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent creates a universal testing framework that can handle multiple network modes (CDMA, GSM, UMTS, LTE) and multiple system selection scenarios through a single automated system, allowing one system to perform multiple testing functions rather than requiring separate specialized systems for each mode

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces a parser as an intermediary component that sits between the UICC card and the test execution system, automatically extracting and structuring the complex MMSS information into a standardized format that simplifies subsequent processing and testing operations

Inventive Principle:

Principle #24Intermediary (Mediator)

3Productivity

If automated testing is implemented, then productivity increases, but measurement precision may deteriorate

Engineering Contradiction:

Improvetesting efficiencyVSAvoidtesting accuracy

Core Design Contradiction:

ProductivityVSMeasurement precision

Solution Approach 1:

The automated testing system performs self-verification by comparing actual device behavior against expected outcomes derived from the parsed UICC data, automatically identifying discrepancies without requiring manual validation, thus maintaining precision while achieving automation

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent implements automated feedback mechanisms where test results are immediately analyzed and compared against expected behavior based on MMSS information, with the system automatically adjusting and re-testing if deviations are detected, ensuring precision is maintained throughout the automated process

Inventive Principle:

Principle #23Feedback
