Wireless Charging Pad Automatic PED Pairing

Solution Overview

Problem

Existing methods for pairing passenger electronic devices (PEDs) with in-flight entertainment and communication (IFEC) systems require active user participation, such as scanning QR codes or entering PIN codes, and involve surface touching, which can be inconvenient and increase the risk of infection during health crises.

Innovation Solution

The use of a wireless charging platform to detect and pair PEDs with the IFEC system by exchanging credential data and establishing a secure connection without the need for user input or surface contact, utilizing protocols like Qi for wireless charging and data exchange.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If QR code scanning or PIN code entry is used for pairing, then secure connection is established, but user convenience deteriorates and health risk increases due to surface touching

Engineering Contradiction:

Improvesecure connectionVSAvoiduser convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system performs pairing automatically without requiring user actions. When a PED is placed on the wireless charging platform, the system autonomously detects the device, initiates pairing through the first communication link, and establishes the second communication link, eliminating the need for users to scan QR codes or enter PIN codes.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces mechanical contact-based pairing methods (QR code scanning, physical buttons) with wireless communication protocols. The first communication link enables automatic data exchange over the wireless charging platform, substituting physical interaction with electromagnetic field-based communication.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Core Design Contradiction:

ReliabilityVSExtent of automation

Solution Approach 1:

The system performs pairing automatically without requiring user actions. When a PED is placed on the wireless charging platform, the system autonomously detects the device, initiates pairing through the first communication link, and establishes the second communication link, eliminating the need for users to scan QR codes or enter PIN codes.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system prepares pairing credentials and communication links in advance. The wireless charging platform is pre-configured with the capability to exchange pairing information through the first communication link, so that when a PED is placed on it, the pairing process can immediately commence without user intervention.
