Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the battery save function is enabled with intermittent reception mode, then power consumption is reduced and battery life is extended, but the device cannot receive voice signals during sleep periods, compromising communication reliability during emergencies
Solution Approach 1:
The patent implements dynamic switching between enabled and disabled states of the intermittent reception mode through function switching signals. Devices can transition from a low-power intermittent reception state (with regular sleep and reception waiting periods) to a full reception state when emergency communication is needed, and vice versa. This dynamic state change allows the system to adapt power consumption and communication reliability to current operational requirements.
Solution Approach 2:
The patent employs feedback mechanisms where devices transmit function switching signals to other devices in the group and receive responses or additional function switching signals. When one device detects an emergency situation or needs to communicate, it sends a function switching signal to disable intermittent reception mode in other devices, ensuring they are available to receive communications. The feedback loop through response signals confirms the state changes across the network.
2Duration of action of stationary object
If the device operates in intermittent reception mode with regular sleep periods, then battery life is extended, but emergency voice signals transmitted during sleep periods are missed, reducing responsiveness to critical situations
Solution Approach 1:
The patent implements preliminary action by having devices transmit function switching signals in advance to switch other devices from intermittent reception mode to a state where they can continuously receive signals. When an emergency situation is anticipated or detected, the system proactively disables sleep modes in receiving devices before critical communications are transmitted, ensuring no emergency signals are missed while minimizing the duration of high power consumption.
3Loss of energy
If the battery save function is enabled, then energy efficiency is improved, but the device enters sleep state where it cannot receive or respond to communication signals, reducing system interoperability during group communication
Solution Approach 1:
The patent implements universality by designing a function switching signal mechanism that works across all devices in the wireless communication group regardless of their current power save state. The function switching signals and response signals use standard communication protocols that both devices in intermittent reception mode and devices in full reception mode can understand and process, ensuring seamless interoperability. This allows the system to maintain energy efficiency for individual devices while achieving coordinated group communication when needed.

AI summary
A wireless communication device that has an intermittent reception mode in which a reception waiting state and a sleep state are repeated at regular intervals includes: a function switching signal generation unit configured to generate a function switching signal for switching between an enabled state and a disabled state of the intermittent reception mode; a transmission unit configured to transmit the generated function switching signal to other wireless communication devices; a reception unit configured to receive, from the other wireless communication devices, one of a response signal for the transmitted function switching signal and the function switching signal; and a function switching unit configured to switch between the enabled state and the disabled state of the intermittent reception mode in accordance with one of the generated function switching signal and the received function switching signal.
