Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual input of virtual route is used based on previous control experience, then the route can be generated, but input errors and format discrepancies occur

Engineering Contradiction:
Improvevirtual route generationVSAvoidinput accuracy
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system automatically generates virtual routes by extracting route point statistics from historical flight plan data, eliminating the need for manual input and subsequent human errors. The automated extraction and standardization process ensures consistent and accurate route generation without relying on operator experience.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system copies and analyzes historical flight plan routes from databases to extract statistical patterns. By copying previous accurate flight plan data and processing it through automated extraction algorithms, the system replicates the accuracy of manual expertise without human intervention.

Inventive Principle:
Principle #26Copying

2Device complexity

If text comparison method is used to select flight route, then the process is simple, but routes with different display formats are not correctly identified as same

Engineering Contradiction:
Improveroute selection processVSAvoidroute identification accuracy
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The system segments the flight plan route into discrete route points and extracts statistical information for each route point. This segmentation allows for precise matching and identification of routes regardless of display format variations, as each segment can be independently analyzed and compared.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system changes the parameter of route representation from raw text strings to standardized route point statistics. By transforming routes into a standardized format based on extracted route point data, the system enables accurate comparison and identification of equivalent routes despite different display formats.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If schedule information only is used for prediction, then the system can operate without flight plan submission, but route accuracy is insufficient

Engineering Contradiction:
Improveprediction capabilityVSAvoidroute prediction accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The system performs preliminary extraction and analysis of route point statistics from historical flight plan data before actual prediction is needed. By pre-processing and storing standardized route point information in databases, the system can quickly and accurately generate virtual routes when prediction is required, without waiting for flight plan submissions.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system introduces route point statistics as an intermediary between schedule information and final route prediction. This intermediary layer extracts and standardizes route information from historical data, enabling accurate virtual route generation based on schedule information alone when flight plans are not submitted.

Inventive Principle:
Principle #24Intermediary (Mediator)
