Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual review of SPEP results is performed by specialists, then diagnostic accuracy is maintained, but time consumption and training requirements increase

Engineering Contradiction:

Improvediagnostic accuracyVSAvoidtime consumption

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent introduces an automated interpretation system that acts as an intermediary between the SPEP data generation and final diagnostic reporting. This system includes a database of reference patterns and an automated comparison mechanism that assists specialists without replacing them entirely, thereby maintaining diagnostic accuracy while reducing time consumption.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system enables self-service interpretation by storing reference SPEP patterns and allowing the automated system to independently compare new results against these references. This reduces the need for extensive specialist training and time investment while maintaining reliable diagnostic outcomes.

Inventive Principle:

Principle #25Self-service

2Reliability

If manual review by specialists is used, then diagnostic interpretation is performed, but transcriptional errors and inconsistency increase

Engineering Contradiction:

Improvediagnostic interpretation qualityVSAvoidtranscriptional errors

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The system creates digital copies of reference SPEP patterns and stores them in a database. These digital copies can be automatically compared with new results, eliminating manual transcription and reducing transcriptional errors while maintaining interpretation quality.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The automated system provides feedback by comparing new SPEP results against stored reference patterns and generating standardized interpretations. This reduces inconsistency between different reviewers and eliminates transcriptional errors associated with manual data handling.

Inventive Principle:

Principle #23Feedback

3Productivity

If automated interpretation is implemented, then time efficiency and standardization improve, but complexity of the system increases

Engineering Contradiction:

Improvetime efficiencyVSAvoidsystem complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The system performs preliminary actions by pre-storing reference SPEP patterns and interpretation criteria in a database before actual diagnostic work begins. This preparation work is done once and reused repeatedly, improving time efficiency without adding complexity to the actual interpretation process.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The interpretation system is segmented into distinct functional modules: data acquisition, pattern matching, comparison logic, and report generation. This modular structure manages system complexity while maintaining high productivity through automated processing.

Inventive Principle:

Principle #1Segmentation
