Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If IP system is employed in the transport system for broadcasting service, then convergence service of broadcasting and communication can be realized, but it becomes difficult to effectively integrate and differentiate between broadcasted and communication-provided services
Solution Approach 1:
The patent segments service information into distinct components: transfer type information (broadcast/communication), component identification information, and acquisition method information. This segmentation allows the reception device to clearly differentiate between broadcasted and communication-provided services, resolving the complexity issue while maintaining convergence capability
Solution Approach 2:
The patent adds a new dimension of information layering by introducing transfer type information as a separate attribute dimension. This allows services to be identified not just by content but by their delivery mechanism dimension, enabling effective integration while maintaining clear differentiation between broadcasting and communication services
2Adaptability or versatility
If common SI and PG information is used across broadcasting and communication domains, then service integration is improved, but it becomes difficult to identify acquisition methods for different service types
Solution Approach 1:
The patent introduces transfer type information as an intermediary element that mediates between the common service information (SI/PG) and the acquisition method. This intermediary carries the necessary distinction information without requiring separate information structures, thus maintaining service integration while preventing information loss about acquisition methods
Solution Approach 2:
The patent changes the parameter structure of service information by adding transfer type as a new parameter attribute. This parameter change allows the same service information framework to convey both common service details and delivery-specific acquisition methods, resolving the information loss problem while maintaining integration
3Productivity
If standardized technique for convergence service is established, then service delivery effectiveness is improved, but it requires complex protocol integration at multiple layers
Solution Approach 1:
The patent creates a universal information structure that functions across both broadcasting and communication domains. The transfer type information and component identification framework serve multiple purposes: service differentiation, acquisition method identification, and protocol-agnostic service management, improving delivery effectiveness without proportionally increasing complexity
Solution Approach 2:
The reception device uses the transfer type information to autonomously determine acquisition methods without requiring complex external control. The service information itself contains the instructions needed for self-service acquisition, simplifying the protocol integration while maintaining effective service delivery
