Solution Overview

Problem

Aircraft communication systems face challenges in automatically configuring wireless routers to connect to varying airport networks, lacking standardization, which affects data transfer efficiency and security across different airports.

Innovation Solution

The implementation of an Airport Gatelink Information (AGI) file that loads specific configuration parameters onto a wireless IP router, enabling it to adapt to different airport environments by specifying network preferences, timeouts, SSID, security info, and IP settings, ensuring secure and efficient connections over WiFi or Cellular networks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If satellite communications are used for data transfer, then availability is improved (both on ground and during flight), but cost increases significantly and delivery rates are restricted

Engineering Contradiction:
ImproveavailabilityVSAvoiddelivery rate
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system dynamically switches between different communication networks (satellite, cellular, WiFi) based on availability and performance conditions. The wireless router automatically adapts its communication path by monitoring network status and selecting the best available network, allowing the system to optimize delivery rates when possible networks are available while maintaining reliability when needed.

Inventive Principle:
Principle #15Dynamics

2Productivity

If manual transportation using removable disks is used, then cost is reduced, but effectiveness and convenience deteriorate

Engineering Contradiction:
ImprovecostVSAvoideffectiveness
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent replaces the mechanical manual disk transfer process with an automated wireless communication system. The wireless router on the aircraft automatically establishes connections to ground networks and transfers data without requiring physical removal and insertion of disks, thereby maintaining low cost while significantly improving effectiveness and convenience.

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

3Productivity

If WiFi and Cellular networks are used, then cost and delivery rates are improved, but availability during flight deteriorates

Engineering Contradiction:
Improvecost and delivery rateVSAvoidavailability during flight
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system dynamically monitors the availability of different communication networks and switches between them based on current conditions. When WiFi or cellular networks are available and provide better delivery rates, the system uses them. When flight conditions prevent access to these networks, the system automatically switches to satellite communications, thus optimizing both cost/performance and availability.

Inventive Principle:
Principle #15Dynamics

4Ease of operation

If automatic configuration of wireless routers is implemented, then ease of operation is improved, but device complexity increases

Engineering Contradiction:
Improveautomatic configurationVSAvoidconfiguration system
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The wireless router is equipped with self-service capabilities that allow it to automatically configure itself by reading airport-specific parameters from the AGI file and autonomously establishing connections to ground networks. This eliminates the need for manual pilot or crew configuration while the embedded processing unit handles the complexity of network selection, authentication, and data transfer routing.

Inventive Principle:
Principle #25Self-service
