Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If applications are received and processed individually from interactive network, then application processing flexibility is improved, but application management complexity increases
Solution Approach 1:
The patent merges multiple application information tables (AITs) received from the interactive network into a single unified AIT structure. This consolidation allows the receiver to manage multiple applications through a single data structure, reducing processing complexity while maintaining the ability to handle diverse application types and sources flexibly.
Solution Approach 2:
The patent creates a universal AIT structure that can accommodate various application types (broadcast applications, interactive network applications, and combinations) within a single framework. This multi-functional data structure enables the receiver to process different application sources through standardized procedures, reducing management complexity while preserving processing flexibility.
2Measurement precision
If application information tables are received and processed, then application identification accuracy is improved, but processing time increases
Solution Approach 1:
The patent performs preliminary processing of application information tables by pre-identifying and organizing application entries before they are fully processed. The receiver pre-parsees AIT data to extract application identifiers and categorize applications, enabling faster subsequent processing and reducing the time required for application identification while maintaining accuracy.
Solution Approach 2:
The patent segments the application information table processing into distinct phases: reception, preliminary parsing, application identification, and full processing. This segmentation allows the receiver to perform quick preliminary actions to identify applications without waiting for complete data processing, thereby reducing overall processing time while maintaining identification accuracy.
3Productivity
If multiple applications are processed efficiently, then productivity is improved, but user interface customization capability deteriorates
Solution Approach 1:
The patent applies local quality by allowing different portions of the unified AIT to be processed with different levels of detail and customization based on application type. Critical application identifiers and user interface parameters are processed with high precision for customization, while less critical data is processed more efficiently, thus maintaining both productivity and UI customization capability.
Solution Approach 2:
The patent implements dynamic processing where the receiver can adapt its processing depth and UI customization level based on real-time needs. The system dynamically adjusts between efficient batch processing for productivity and detailed customization processing when users interact with specific applications, thereby maintaining both efficiency and customization capability.
