Solution Overview

Problem

Current aircraft communication systems, such as WiFi and datalink services, are vulnerable to interception and require heavy, costly hardware, increasing weight and operational costs due to the need for equipment and antennas, which is not desirable for secure data exchange between aircraft and ground operators.

Innovation Solution

Implementing a near-field communication interface within the aircraft and a handheld device with a compatible near-field communication interface for secure, local data exchange, utilizing peer-to-peer communication and cryptographic protocols to minimize eavesdropping risks and reduce hardware requirements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of stationary object

If WiFi and datalink services are used for data exchange, then communication distance is improved, but security against interception deteriorates

Engineering Contradiction:
Improvecommunication distanceVSAvoidinterception risk
Core Design Contradiction:
Length of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a portable computing device as an intermediary between the aircraft system and ground operators. Data is transmitted from the aircraft to the portable device via near-field communication, then forwarded to ground operators through cellular networks. This intermediary approach allows secure local transmission while using public networks only for non-sensitive routing, resolving the contradiction between communication distance and security.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If WiFi and datalink services are implemented, then communication capability is improved, but device complexity and weight increase

Engineering Contradiction:
Improvecommunication capabilityVSAvoidhardware requirements
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts the heavy, complex communication hardware (WiFi antennas, datalink equipment) from the aircraft and relocates it to a portable computing device that the maintenance operator carries. The aircraft only needs a lightweight near-field communication interface, while the portable device handles all complex communication functions, significantly reducing aircraft hardware requirements and weight.

Inventive Principle:
Principle #2Taking out (Extraction)

3Reliability

If dedicated communication hardware is installed on aircraft, then communication reliability is improved, but cost of operation increases

Engineering Contradiction:
Improvecommunication reliabilityVSAvoidoperational cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent makes the communication system universal by using a portable computing device that can serve multiple functions: near-field communication with the aircraft, cellular network connectivity for ground communication, and data processing. This single multi-functional device replaces multiple dedicated systems, reducing hardware costs and operational expenses while maintaining reliability through cryptographic protocols.

Inventive Principle:
Principle #6Universality (Multi-functionality)
