Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If conventional GNSS positioning is used for air vehicle navigation, then the system is simple and easy to operate, but the positioning accuracy is insufficient leading to increased accident risks

Engineering Contradiction:

Improvepositioning accuracyVSAvoidsystem complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent introduces a determination device as an intermediary component that receives correction information from reference stations and processes it to generate accurate positional information. This mediator resolves the contradiction by adding the necessary complexity in a controlled manner to achieve high-precision positioning without requiring complete system redesign

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The positioning system is segmented into multiple independent components: reference stations that provide correction information, a determination device that processes the data, and air vehicles that receive positional information. This segmentation allows each component to be optimized independently, improving overall positioning accuracy while managing system complexity

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If manual path setting is used for air vehicles, then the system is simple, but the usability and efficiency are reduced

Engineering Contradiction:

Improvepath setting usabilityVSAvoidpath determination efficiency

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The determination device automatically determines flight paths by processing correction information and calculating optimal routes without requiring manual intervention. This self-service capability improves both usability and efficiency simultaneously, as the system performs path determination autonomously based on real-time positional data

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system dynamically changes path parameters based on real-time positional information and correction data. By automatically adjusting flight path parameters such as waypoints, altitude, and timing, the system enhances usability while maintaining high productivity without manual path setting

Inventive Principle:

Principle #35Parameter changes

AI summary

A determination device according to one embodiment includes an acquiring unit (231) and a determination unit (233). The acquiring unit (231) acquires positional information that is related to a terminal device installed at an arbitrary location serving as a reference for a path of an air vehicle and that is calculated on the basis of correction information that includes information on coordinates of a reference station associated with an area in which the terminal device is positioned and information based on a satellite signal received by the reference station. The determination unit (233) determines a flight path of the air vehicle on the basis of the positional information acquired by the acquiring unit.
