Interactive Aircraft Information System with Segmented Data Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft information systems provide limited interactivity and customization for passengers, failing to match the high interactivity of ground-based services, which restricts personalized information access and entertainment options.
Innovation Solution
An interactive information system for aircraft that combines onboard and offboard data storage, utilizing a computer to generate informative content based on aircraft position, allowing passengers to access and visualize data interactively through a variety of media formats, including maps, sounds, and user profiles, with features like GPS, internet connectivity, voice control, and avatars.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If static content is used for passenger information, then system complexity is reduced, but interactivity and customization capability deteriorate
Solution Approach 1:
The information system is segmented into multiple independent components: onboard data storage device, off-board data storage device, access unit, computer for generating informative data, and output unit. This segmentation allows each component to perform its specific function independently, enabling interactivity and customization without requiring the entire system to be complex.
Solution Approach 2:
The access unit acts as an intermediary between the onboard/off-board data storage devices and the computer. It manages data retrieval and transmission, allowing passengers to access and customize information without directly complicating the core processing system. The output unit serves as another intermediary that presents customized information to passengers in various formats.
2Loss of information
If onboard data storage only is used, then system reliability is improved, but information freshness and variety deteriorate
Solution Approach 1:
The system merges onboard data storage device and off-board data storage device into a unified information architecture. The onboard storage provides reliable local access to essential data, while the off-board storage (accessible via access unit during flight) supplements with fresh and diverse information such as current events, weather updates, and additional entertainment content.
Solution Approach 2:
Data is pre-loaded onto the onboard data storage device before the flight to ensure immediate access and system reliability. Additional data can be accessed from off-board storage during the flight if needed, combining the benefits of pre-prepared reliable data with the flexibility of supplementary fresh data.
3Ease of operation
If personalized information access is implemented, then passenger satisfaction is improved, but data processing requirements increase
Solution Approach 1:
The system implements local quality by tailoring information presentation to individual passenger preferences. The computer generates informative data customized to each passenger's interests, language, and preferences stored in the system. The output unit delivers this personalized content through the passenger's selected format (visual, auditory, or both), making the system easy to operate for each user without requiring excessive processing of universal content.

AI summary
An interactive information system is indicated for an aircraft to provide passengers with information, which access both an onboard data storage device and an off-board data storage device. A computer uses the onboard and off-board data to compute informative data, which are then visualized to the passenger. The passenger can interactively determine the form and type of data generation and preparation at any time.
