Solution Overview

Problem

Conventional methods for updating in-flight entertainment and communications (IFEC) systems on aircraft are labor-intensive, time-consuming, and prone to human errors, making frequent updates of multimedia content and software challenging.

Innovation Solution

A central administrative fleet management system automates the decision-making process for updating IFEC systems by using a ground-based system to manage an aircraft installation plan, which defines software content requirements for each aircraft, and communicates these plans to onboard systems for automated updates.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual updating methods are used, then personnel can physically transfer content to aircraft, but the process becomes labor-intensive and time-consuming

Engineering Contradiction:

Improveupdate reliabilityVSAvoidupdate efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent replaces the manual mechanical process of physically carrying storage devices and manually transferring content with an automated electronic distribution system. The system uses electronic messages transmitted over communication networks to automatically initiate and manage content updates, eliminating the need for personnel to manually handle physical media and perform manual transfer operations.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables self-service updating by allowing aircraft IFEC systems to automatically receive, process, and install content updates without requiring manual intervention. The automated message-driven architecture allows the system to self-manage the entire update process from initiation to completion, including automatic content transfer and installation scheduling.

Inventive Principle:

Principle #25Self-service

2Adaptability or versatility

If frequent updates are implemented, then latest multimedia content can be provided, but manual transfer processes prohibit frequent updating

Engineering Contradiction:

Improvecontent freshnessVSAvoidupdate time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent establishes continuous content update capability through an automated system that can operate continuously without interruption. The electronic message-driven architecture allows updates to be initiated, transferred, and installed continuously as content becomes available, eliminating the periodic interruptions inherent in manual update processes and enabling frequent or even real-time content refreshes.

Inventive Principle:

Principle #20Continuity of useful action

Solution Approach 2:

The system performs preliminary actions by pre-configuring update messages and preparing content transfers in advance. The automated system can queue update messages, pre-stage content, and schedule installations before actual deployment, allowing frequent updates to be executed efficiently without causing operational disruptions during flight.

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If manual content transfer is performed, then select content can be updated, but human errors occur during the process

Engineering Contradiction:

Improveupdate simplicityVSAvoidupdate accuracy

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent implements feedback mechanisms through automated confirmation and status tracking of content updates. The electronic message system provides automatic acknowledgment of received updates, tracks installation status, and can trigger retransmission if errors occur. This automated feedback loop eliminates human error in tracking and confirming update completion while maintaining operational simplicity.

Inventive Principle:

Principle #23Feedback

4Productivity

If automated systems are implemented, then update efficiency increases, but system complexity increases

Engineering Contradiction:

Improveupdate efficiencyVSAvoidsystem complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent achieves efficiency gains through a universal message-driven architecture that handles multiple functions through a single standardized interface. The electronic message system can initiate content transfers, schedule installations, track status, and manage errors using the same message protocol, eliminating the need for separate complex control systems for each update function and reducing overall system complexity while maintaining high productivity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Systems, devices, and methods updating in-flight entertainment and communications (IFEC) systems in aircraft are disclosed herein. In some implementations, a central administrative fleet management system includes a database configured to store an aircraft installation plan and a managing processor operably coupled to the database. The aircraft installation plan can define a planned set of software content to be stored on an IFEC system of a particular aircraft. The managing processor can be configured to receive an identity of the aircraft, identify a portion of the aircraft installation plan corresponding to the aircraft based on the received identity of the aircraft, and communicate the identified portion of the aircraft installation plan to the IFEC system. The IFEC system can then be updated using software content received from a portable content loader operably coupled to the IFEC system based on the identified portion of the aircraft installation plan.
