Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile electronic devices face inefficiencies in handling data delivery due to limited computational resources and the need for compromises in receiving equipment, particularly when handling broadcast data.
Innovation Solution
A method and system for delivering Non-Real-Time (NRT) data to mobile devices, involving data segmentation, NRT scheduling, and Universal Resource Locators (URLs) with enhanced protection, allowing devices to store, format, and broadcast multimedia files with network identifiers, enabling efficient retrieval via broadcast or internet when signal fades occur.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If broadcast data is delivered to mobile electronic devices, then data delivery capability is improved, but device resource efficiency deteriorates due to limited computational capabilities
Solution Approach 1:
The broadcast data stream is segmented into multiple data packets that are transmitted at different priority levels. High-priority packets contain essential data for immediate playback, while low-priority packets contain additional content. This segmentation allows mobile devices to receive and process data in manageable portions, reducing computational burden while maintaining delivery capability.
Solution Approach 2:
The system performs preliminary actions by buffering high-priority data packets before they are fully processed by the mobile device. The broadcast receiver stores prioritized data in a buffer, allowing the mobile device to access essential information without immediately processing the entire data stream, thus conserving computational resources.
2Weight of moving object
If receiving equipment is made compact for mobile devices, then device portability is improved, but signal reception strength deteriorates
Solution Approach 1:
The system dynamically adjusts the reception strategy based on signal conditions. When signal strength is sufficient, the mobile device can use simpler reception modes. When signal fades occur, the system automatically switches to alternative retrieval methods such as requesting data from a server via wireless network, ensuring continuous access without requiring high-power reception equipment.
Solution Approach 2:
A server acts as an intermediary between the broadcast transmitter and the mobile device. When broadcast signal reception fails due to signal fades or mobility issues, the server provides alternative data delivery paths through wireless networks, ensuring reliable data access without requiring enhanced physical reception capabilities in the mobile device.
3Area of stationary object
If data is transmitted via broadcast to mobile devices, then data delivery coverage is improved, but data retrieval reliability deteriorates during signal fades
Solution Approach 1:
The system implements periodic actions by continuously monitoring signal conditions and periodically attempting to retrieve data through alternative means when broadcast reception fails. The mobile device can request data from the server at scheduled intervals or when signal degradation is detected, ensuring reliable retrieval without requiring continuous broadcast signal availability.
Solution Approach 2:
The system uses feedback mechanisms where the mobile device reports its reception status and signal conditions to the server. Based on this feedback, the server adjusts its data delivery strategy, providing alternative data paths or retry opportunities when broadcast signal reception is poor, thereby maintaining high reliability despite signal fades.
