Variable Viewing Time Communication Device for In-Flight Content
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Passengers on vehicles like airplanes cannot always finish viewing audio visual content due to limited viewing time, and they lack the ability to skip or fast-forward through parts they may not want to watch.
Innovation Solution
A communication device and system that calculate available viewing time and replay time, generating warnings if replay time exceeds viewing time, and allowing fast-forward replay options to ensure content can be completed within the time frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If content is transmitted to allow viewing within limited available time, then passengers can view content during the flight, but passengers cannot finish viewing content if the replay time exceeds the available viewing time
Solution Approach 1:
The system performs preliminary calculation of replay time and compares it with available viewing time before content transmission begins. This advance assessment allows the system to determine whether the content can be fully viewed within the limited time frame, enabling passengers to make informed decisions about content selection and viewing preferences before time is lost.
2Ease of operation
If the system automatically determines replay speed based on available time, then content can be viewed within the time limit, but passengers cannot choose to skip or fast-forward through parts they may not want to watch
Solution Approach 1:
The system dynamically adjusts replay speed based on real-time comparison between available viewing time and calculated replay time. When the replay time exceeds available viewing time, the system automatically increases the replay speed to allow content completion within the time limit, while still providing passengers with control options to skip or fast-forward through specific parts based on their preferences.
3Difficulty of detecting and measuring
If the system provides warning information when replay time exceeds available viewing time, then passengers can determine whether to continue viewing, but the system complexity increases with additional calculation and determination units
Solution Approach 1:
The available viewing time calculation unit and replay time calculation unit are integrated into the existing communication device architecture, serving multiple functions including time management, content selection guidance, and user decision support. This multi-functional approach provides comprehensive time management awareness without proportionally increasing system complexity.

AI summary
The communication device is installed in a predetermined space. The communication device receives and displays content distributed only within a variable available viewing time. The communication device includes an available viewing time calculation unit configured to calculate the available viewing time, a replay time calculation unit configured to calculate the replay time needed to replay predetermined content, a warning determination unit configured to compare the replay time and the available viewing time and generate warning information when the replay time exceeds the available viewing time, and a display unit configured to display the warning information generated by the warning determination unit.
