Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual evaluation of log files is performed by experts, then testing faults can be identified and remedied, but the process becomes extremely cumbersome and time-consuming

Engineering Contradiction:
Improvefault identification accuracyVSAvoidtesting procedure duration
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system enables self-service by automatically analyzing log files and identifying test faults without requiring expert intervention. The automated analysis unit processes log files, identifies configuration errors and execution faults, and generates remediation suggestions, allowing the testing system to diagnose and remedy its own problems independently.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces the manual mechanical process of expert analysis with an automated electronic system. The analyzing unit uses electronic processing to automatically parse log files, detect faults, and generate remediation steps, substituting the human expert's manual scrutiny with an automated computational system that operates faster and without fatigue.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If experts manually scrutinize log files to identify testing faults, then accurate fault identification is achieved, but the process requires significant expert knowledge and resources

Engineering Contradiction:
Improvefault detection accuracyVSAvoidexpert knowledge requirement
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system encapsulates expert knowledge within the automated analyzing unit, which self-services by automatically applying fault detection algorithms and patterns. The system stores and applies expert knowledge in the form of predefined fault patterns and analysis rules, eliminating the need for human experts to manually apply their knowledge while maintaining high detection accuracy.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent transforms the abstract concept of expert knowledge into concrete, machine-processable parameters and patterns. By converting expert diagnostic criteria into structured analysis rules and patterns that can be automatically applied to log files, the system maintains measurement precision while removing the complexity of requiring human expert knowledge.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If automated test procedures are executed, then testing efficiency is improved, but testing faults can occur due to misconfiguration or improper execution

Engineering Contradiction:
Improvetesting efficiencyVSAvoidtest execution reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system implements feedback by automatically monitoring test executions through log file analysis. When faults are detected, the system generates remediation suggestions and can automatically apply corrections to test configurations, creating a closed-loop feedback system that continuously improves test execution reliability while maintaining high productivity.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent applies preliminary action by proactively analyzing log files and identifying potential configuration errors before they cause test failures. The system performs preliminary fault detection and generates remediation suggestions in advance, allowing corrections to be applied before executing subsequent test procedures, thereby preventing reliability issues before they occur.

Inventive Principle:
Principle #10Preliminary action
