Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Aircraft in-flight entertainment (IFE) systems face challenges in passenger usability due to complex operation and limited functionality, and passengers struggle to integrate personal electronic devices (PEDs) effectively with these systems for enhanced entertainment options.

Innovation Solution

A communications system that uses a registration token image displayed on IFE passenger seat displays, allowing PEDs to register with the IFE system via optical sensing, enabling PEDs to function as remote controls or entertainment sources, and allowing passengers to access a broader range of content wirelessly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If wireless registration schemes are used to integrate PEDs with IFE systems, then passenger entertainment options are enhanced, but the registration process becomes complex and difficult to operate

Engineering Contradiction:

ImprovePED integration capabilityVSAvoidRegistration process simplicity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent uses visual registration tokens displayed on the IFE screen that the PED camera captures. Instead of complex wireless pairing protocols, the system creates a visual copy of the registration token that the PED optically senses and processes, simplifying the integration process while maintaining security and functionality

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent replaces manual wireless configuration procedures with an optical sensing mechanism. The PED uses its camera to capture the registration token displayed on the IFE screen, automatically processing the visual information to establish the wireless connection, eliminating the need for manual network configuration and authentication steps

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If traditional IFE control interfaces are used, then system reliability is maintained, but user control functionality is limited and awkward to operate

Engineering Contradiction:

ImproveIFE system stabilityVSAvoidControl interface functionality

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent enables the PED to serve multiple functions: it acts as both a media player for personal content and a remote control for the IFE system. The same device that plays personal videos can also control IFE functions through the established wireless connection, eliminating the need for separate physical remote controls and expanding control capabilities

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent transforms the static IFE control interface into a dynamic, adaptable system. The PED serves as a flexible control interface that can be positioned anywhere in the passenger's vicinity, unlike fixed seatback controls. The control capabilities dynamically adjust based on the PED's capabilities and the established connection with the IFE system

Inventive Principle:

Principle #15Dynamics

3Device complexity

If fixed IFE displays are used, then system simplicity is maintained, but viewing accessibility and content variety are limited

Engineering Contradiction:

ImproveIFE system structureVSAvoidContent access options

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent merges the IFE system with the passenger's personal entertainment device. By integrating the PED into the IFE ecosystem through wireless connection and optical registration, the system combines the airline's content library with the passenger's personal media, creating a unified entertainment experience that leverages both systems' capabilities

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A communications system for an aircraft includes an aircraft in-flight entertainment (IFE) system, and at least one personal electronic device (PED) carried by an aircraft passenger. The aircraft IFE system includes an IFE video entertainment source, IFE passenger seat displays, an IFE wireless transceiver, and an IFE controller. The IFE controller is for selectively displaying video from the IFE entertainment source on the IFE passenger seat displays, and for generating a respective registration token image on each IFE passenger seat display. The PED includes a PED optical sensor, a PED wireless transceiver, and a PED controller. The PED controller is for communicating with the IFE wireless transceiver via the PED wireless transceiver based upon the PED optical sensor sensing the registration token image.
