Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single link is used for data transmission, then the transmission path is simple, but the link may be occupied for a long period of time
Solution Approach 1:
The patent divides the transmission path into multiple links (first link and second link) with different channels. The management unit manages multiple links and allocates channels to different transmission units, enabling data to be transmitted through multiple paths simultaneously. This segmentation allows the system to avoid long occupancy of a single link while maintaining simple individual link structures.
2Duration of action of moving object
If multiple links are established for data transmission, then the link occupancy period is reduced, but the system complexity increases
Solution Approach 1:
The management unit performs multiple functions: establishing multilink, allocating channels to transmission units, managing carrier sense processing timing, and coordinating data transmission across multiple links. This multi-functionality consolidates what would otherwise require separate complex components, reducing overall system complexity while enabling reduced link occupancy through multiple paths.
Solution Approach 2:
The management unit pre-establishes multilink and allocates channels before data transmission begins. The carrier sense processing is initiated at predetermined timing based on planned transmission schedules. This preliminary configuration avoids the need for dynamic complex decision-making during transmission, simplifying the overall system architecture while achieving efficient link utilization.
3Device complexity
If carrier sense processing is performed sequentially for each link, then the control is simple, but the transmission efficiency decreases
Solution Approach 1:
The management unit determines and sets the timing for carrier sense processing in advance based on the established multilink configuration and channel allocation. Transmission units perform carrier sense at predetermined timing without requiring complex real-time coordination. This preliminary timing arrangement simplifies control while enabling overlapping carrier sense operations across multiple links, thereby improving transmission efficiency.
Solution Approach 2:
Multiple transmission units perform carrier sense processing simultaneously or overlappingly on different links, rather than sequentially. The management unit coordinates this continuous useful action across multiple channels, ensuring that carrier sense is conducted without unnecessary interruptions or idle waiting periods, thus improving overall transmission efficiency while maintaining manageable control complexity.

AI summary
A transmission station includes a first transmission unit, a second transmission unit, and a management unit. The management unit is configured establish, with a reception station, a multilink in which first channel is allocated to the first transmission unit and a second channel is allocated to the second transmission unit. The second transmission unit is configured to start carrier sense processing regarding second data during an occupancy period in which the first transmission unit transmits first data, and transmit the second data subsequent to the first data in a case where a transmission right is acquired by the carrier sense processing.
