Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wake-on LAN or wake-on wireless LAN methods are used for remote activation, then remote activation can be implemented using existing network infrastructure, but a considerable amount of power is consumed in awaiting reception of a magic packet
Solution Approach 1:
The communication device performs periodic channel sensing at predetermined intervals to detect activation signals, rather than continuously monitoring the channel. This periodic detection approach maintains remote activation capability while significantly reducing power consumption compared to continuous monitoring methods.
Solution Approach 2:
The device uses its own communication infrastructure to send and receive activation signals through the network. The communication device can autonomously detect activation signals and transition from standby to active state without requiring external power management intervention, enabling self-powered remote activation.
2Reliability
If transmission suppression time is set to prevent interference from other devices, then activation signal transmission becomes more accurate, but communication with other devices may be affected
Solution Approach 1:
The transmission suppression time (NAV) is set locally for each activation signal transmission based on the specific channel conditions and signal characteristics. This localized adjustment ensures accurate activation signal delivery to the target device while minimizing impact on other communications, as each transmission is optimized independently rather than using a fixed global suppression time.
Solution Approach 2:
The transmission suppression time is dynamically adjusted based on real-time channel conditions and signal requirements. Rather than using a static suppression period, the system adapts the NAV value to match the actual transmission needs, ensuring reliable activation signal delivery while maintaining flexibility for other communications when conditions permit.

AI summary
According to one embodiment, a communication device, which performs communication using a first communication method and a second communication method, converts information to be transmitted into information for forming a pulse that is formed depending on the presence and absence of transmission of a radio wave, according to the first communication method. The communication device decides a suppression time, during which communication with a communication device other than a communication partner is suppressed, on the basis of a result of the conversion. The communication device generates an output signal including the transmission suppression signal, in which the suppression time is set for each first element in the pulse, according to the second communication method, the first element transmitting a radio wave. The communication device transmits a radio wave according to the output signal to the communication partner at timing to transmit a radio wave in the pulse.
