Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If digital broadcast systems transmit large amounts of video/audio data and additional services, then service functionality is improved, but data transmission efficiency deteriorates
Solution Approach 1:
The application file is segmented into multiple packets for transmission over the broadcast network. Each packet contains a portion of the application file data along with necessary routing information, allowing efficient transmission of large data volumes without overwhelming the network bandwidth.
Solution Approach 2:
The patent introduces an application file delivery mechanism that acts as an intermediary between the broadcast content delivery and the receiver's application execution. This intermediary layer manages file transmission, storage, and retrieval, optimizing the flow of data between network and application layers.
2Manufacturing precision
If digital broadcast systems provide HD images, multichannel audio and additional services, then service quality is improved, but network robustness deteriorates
Solution Approach 1:
The system implements error correction coding and redundancy mechanisms in advance of potential transmission failures. Application files are protected with forward error correction codes, and the system can recover from packet losses without requiring retransmission, cushioning against network robustness issues.
3Quantity of substance
If digital broadcast systems handle large amounts of data, then content richness is improved, but transmission efficiency deteriorates
Solution Approach 1:
The patent implements a nested structure where application file packets are embedded within the broadcast data stream. The application file transmission is nested within the existing broadcast framework, utilizing available bandwidth without requiring separate dedicated channels, thus maintaining transmission efficiency while handling large data volumes.
4Ease of operation
If the system transmits customized application files based on user characteristics, then user experience is improved, but system complexity deteriorates
Solution Approach 1:
The system applies local quality by customizing application file transmission based on specific user characteristics and receiver capabilities. Different users receive different application files or different versions of the same application, optimized for their specific devices and preferences, without requiring complete system reconfiguration.
