Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If data is sent intermittently to reduce memory buffer capacity, then memory buffer capacity is reduced, but power consumption increases due to longer data transfer stop periods
Solution Approach 1:
The communication apparatus performs periodic transmission of data frames during intermittent operation, switching between transmission and reception states at regular intervals. This periodic action allows the device to maintain connection while reducing power consumption during reception stop periods, resolving the contradiction between reduced buffer capacity and power consumption.
Solution Approach 2:
The apparatus dynamically switches between normal operation and intermittent operation modes based on data transfer requirements. During intermittent operation, the device alternates between active transmission/reception states and low-power states, adapting its operational characteristics to balance buffer capacity requirements with power consumption constraints.
2Reliability
If normal operation is performed during data transfer stop period on transmission side, then data transfer reliability is maintained, but power consumption increases
Solution Approach 1:
The apparatus maintains continuous connection and operational readiness during intermittent operation by periodically switching between transmission and reception states. This continuous useful action ensures data transfer reliability is maintained while allowing power consumption reduction during reception stop periods through controlled intermittent operation.
Solution Approach 2:
The transmission apparatus preliminarily determines whether the reception apparatus is in intermittent operation mode before transmitting data frames. This preliminary action allows the transmission side to adjust its operation accordingly, maintaining reliability by knowing the reception state while avoiding unnecessary power consumption during reception stop periods.
3Device complexity
If intermittent operation notification is sent without receiving response, then communication protocol simplicity is improved, but data transfer reliability may be compromised
Solution Approach 1:
The apparatus implements feedback mechanisms where the reception apparatus notifies the transmission apparatus of its intermittent operation state. Although the notification is sent without requiring immediate response acknowledgment, this feedback allows the transmission side to adjust its timing and ensure reliable data delivery during appropriate reception windows, maintaining reliability while keeping the protocol simple.
