In-flight Entertainment Wireless Interactivity via Web Browser
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle entertainment systems fail to meet consumer expectations for interactivity and often require costly special software and hardware, limiting device compatibility and excluding non-cellular capable devices, while also lacking effective communication between passenger-owned smart devices and vehicle displays.
Innovation Solution
A vehicular entertainment system that utilizes a wireless network for full duplex communication between a client mobile device and a host computing device, allowing interactive content manipulation through a web browser without additional software installation, enabling passengers to interact with in-vehicle content using their own devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If special system software and applications are required for smart devices to interact with the in-vehicle entertainment system, then interactivity is improved, but device compatibility deteriorates and system cost increases
Solution Approach 1:
The patent applies universality by using a web browser that is already present on various smart devices (Android, iOS, Windows) to access the in-vehicle entertainment system. Instead of requiring device-specific applications, the system provides a universal web-based interface that works across multiple device types and operating systems, thereby improving device compatibility while maintaining interactivity through standard web protocols.
Solution Approach 2:
The patent introduces a wireless network and web server as intermediaries between the passenger's smart device and the in-vehicle entertainment system. The web server hosts the entertainment content and interface through standard web protocols (HTTP, HTTPS), acting as a mediator that enables communication without requiring direct device-specific software, thus resolving the contradiction between interactivity and compatibility.
2Ease of operation
If special system software and applications are installed on smart devices, then interactivity is improved, but system cost increases
Solution Approach 1:
The patent applies self-service by utilizing the web browser that already exists on passenger-owned smart devices. Instead of requiring the system to provide specialized software or applications, the solution leverages the device's own built-in browser to access entertainment content, eliminating the need for additional software installation and reducing system cost while maintaining full interactivity.
Solution Approach 2:
The patent uses copying by implementing the entertainment interface through standard web technologies (HTML, CSS, JavaScript) that can be rendered by any modern web browser. This approach copies the familiar web browsing experience to the in-vehicle context, allowing passengers to interact with entertainment content using their existing browser without requiring specialized software, thereby reducing system complexity and cost.
3Productivity
If cellular communication infrastructure is used for in-vehicle entertainment, then content distribution is enabled, but device compatibility deteriorates by excluding non-cellular devices
Solution Approach 1:
The patent applies universality by using wireless networking capabilities that are universally present on all modern smart devices (WiFi, Bluetooth) instead of relying on cellular communication. This allows both cellular-capable and non-cellular devices (such as tablets without cellular antennas) to access the in-vehicle entertainment system, improving device compatibility while maintaining content distribution through standard wireless protocols.
4Device complexity
If single duplex network protocols are used for communication, then system simplicity is maintained, but interactivity deteriorates due to limited communication capabilities
Solution Approach 1:
The patent applies dynamics by implementing full-duplex communication capabilities through WebSocket or similar protocols that allow simultaneous two-way data transmission between the passenger's device and the in-vehicle system. This dynamic communication model enables real-time interactivity (such as controlling playback, adjusting settings, and receiving updates) while maintaining system simplicity by using standardized web protocols that build upon existing network infrastructure.

AI summary
An in-flight entertainment system that enables a passenger to consume and interact with content presented on an aircraft display screen. Passenger devices wirelessly connect to host computing devices that are kept on the aircraft, which enables the passenger devices to consume in-flight entertainment. Content presented on the passenger device can enable the passenger to interact with content presented on the aircraft display screen, and vice versa. Passenger devices can access in-flight entertainment stored on or accessed by a host computing device via a preinstalled web browser.
