Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for pairing personal electronic devices with vehicle seats lack secure and efficient methods to ensure that only the intended passenger can control seat functions, leading to unauthorized access and operational issues.
Innovation Solution
A system that uses an on-board management system with a data server, wireless communication module, and device pairing software to pair personal electronic devices with seats using electronic boarding passes, passenger manifests, or light identification via pulse width modulation, ensuring secure and authorized control of seat functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing pairing systems use simple wireless communication protocols, then ease of operation is improved, but security is worsened allowing unauthorized access
Solution Approach 1:
The patent introduces an intermediary verification process using boarding pass data and seat assignment information as a mediator between the personal electronic device and the seat control system. This intermediary layer validates the pairing request by checking whether the device's boarding pass matches the assigned seat, thereby maintaining ease of operation while significantly improving security against unauthorized access.
2Reliability
If the system implements strict passenger verification, then access security is improved, but device complexity is worsened
Solution Approach 1:
The patent leverages the multi-functionality of existing personal electronic devices by utilizing their built-in camera, display, and wireless communication capabilities for the pairing process. The device's existing camera is used to capture boarding pass information, the display shows pairing status, and wireless modules handle communication with the seat system. This approach improves security without adding separate dedicated hardware, thereby avoiding increased device complexity.
3Reliability
If the system uses multiple verification methods, then access security is improved, but ease of operation is worsened
Solution Approach 1:
The patent implements preliminary action by having passengers complete the pairing process before the flight or journey begins. The system verifies boarding pass information and assigns seats in advance, so that when the passenger arrives at their seat, the pairing is already established or can be quickly completed by simply presenting the boarding pass. This preliminary verification reduces the operational steps required at the actual seating moment while maintaining high security standards.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system securely pairs personal electronic devices with specific seats, preventing unauthorized access and enhancing the passenger experience by allowing secure control of entertainment, comfort, and environmental systems.
Implementation Method 1
displaying on a monitor installed at the seat of the passenger a light identification associated with the seat via a pulse width modulation communication produced by modulating a backlight of the monitor
Implementation Method 2
The personal electronic device is configured to receive the light identification displayed on the monitor using an imaging device of the personal electronic device
Data Source
AI summary
Systems and methods for pairing a personal electronic device of a passenger with a passenger seat in a vehicle using a PWM light identification, and for allowing the personal electronic device to control passenger in-seat functions and features. The system comprises an on-board video system having an in-seat display system for installation in a vehicle. The on-board video system is configured to communication a PWM light identification from a monitor of the in-seat display system which is captured by an imaging device of the personal electronic device. The on-board video system receives pairing information from the personal electronic device corresponding to the captured light identification via a wireless communication link. The on-board video system then validates the pairing information and pairs the personal electronic device to the passenger seat and authorizes the personal electronic device to control passenger seat functions associated with the passenger seat.
