Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple communication interfaces are used to increase communication quality, then throughput and stability are improved, but communication interruptions occur during interface switching
Solution Approach 1:
The patent implements dynamic switching between single-communication state and multi-communication state based on real-time communication quality assessment. The reception device evaluates communication quality metrics and generates control signals to transition between operational modes, allowing the system to adapt to changing network conditions while maintaining continuous content delivery
Solution Approach 2:
The system changes operational parameters by switching between different communication states (single-interface vs. multi-interface modes). The reception device monitors communication quality parameters and adjusts the number of active communication interfaces accordingly, optimizing performance while minimizing interruptions
2Reliability
If communication interfaces are switched to optimize quality, then communication quality is improved, but interruptions occur during switching
Solution Approach 1:
The reception device performs preliminary assessment of communication quality for multiple interfaces before committing to a switching decision. By evaluating communication quality metrics in advance and preparing control signals proactively, the system minimizes the actual switching time and reduces interruptions to content delivery
3Productivity
If multiple communication interfaces are used, then throughput is increased, but system complexity increases
Solution Approach 1:
The reception device autonomously monitors communication quality metrics and generates control signals for switching between communication states without external intervention. The transmission device automatically adjusts its operation based on received control signals, creating a self-managing system that handles multiple interfaces while maintaining operational simplicity

AI summary
A communication system includes a transmission device including a transmission-side processor, a transmission-side memory, and first and second transmission-side communication interfaces and which transmits frame data and a reception device including a reception-side processor, a reception-side memory, and first and second reception-side communication interfaces. The reception-side processor generates, when the reception-side processor is in a multi-communication state in which pieces of frame data are received through both the first and second reception-side communication interfaces, a control signal for switching to a single-communication state in which the pieces of the frame data are received through one of the first and second reception-side communication interfaces selected based on communication quality. The reception-side processor generates, in the single-communication state, the control signal for switching to the multi-communication state based on the communication quality of one of the first and second reception-side communication interfaces that receives the pieces of the frame data.
