Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed header structure is used in packet transmission, then device complexity is reduced and ease of operation is improved, but adaptability to support various receiving methods and data types deteriorates
Solution Approach 1:
The header structure is made dynamic and configurable rather than fixed. The transmitting apparatus can adapt the header format based on the type of data being transmitted and the receiving method being used, allowing the system to optimize between simplicity and adaptability depending on the specific transmission scenario.
Solution Approach 2:
The patent changes parameters of the header structure (such as field presence, field length, and field organization) based on the transmission requirements. By dynamically adjusting header parameters, the system maintains ease of operation for standard cases while gaining adaptability for specialized receiving methods and data types.
2Adaptability or versatility
If various optional fields and extension fields are added to support different data types and services, then adaptability is improved, but device complexity and processing overhead increase
Solution Approach 1:
The header is segmented into mandatory fields and optional/extension fields. This segmentation allows the basic header structure to remain simple and easy to process, while optional fields can be added only when specific adaptability is required. The receiving apparatus can choose to process only the mandatory fields for simple cases, reducing complexity.
Solution Approach 2:
The header structure is designed with universal mandatory fields that handle common transmission requirements, and optional extension fields that provide specialized functionality when needed. This multi-functional design allows a single header structure to serve multiple purposes without requiring completely different structures for different data types and services.
3Reliability
If existing broadcasting standards are used, then reliability and stability are maintained, but productivity and ability to provide high-quality digitized services deteriorate
Solution Approach 1:
The patent introduces dynamic packet formatting capabilities that allow the system to adapt to modern high-speed transmission requirements while maintaining compatibility with existing broadcasting standards. This enables improved productivity through efficient data processing and transmission without sacrificing the reliability ensured by standard compliance.
