Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the receiving circuit is kept in active state to receive wake-up signals, then data communication reliability is improved, but power consumption increases and battery life decreases
Solution Approach 1:
The receiving circuit operates in periodic cycles, alternating between active and sleep states. During each cycle, the circuit activates to receive wake-up signals for a predetermined period, then enters sleep mode to conserve battery power. This periodic operation resolves the contradiction by ensuring the circuit is available for communication when needed while minimizing power consumption during idle periods.
Solution Approach 2:
The system pre-determines the activation period and sleep period before operation begins. By establishing these time parameters in advance, the receiving circuit can automatically switch between active and sleep states without continuous monitoring, thereby reducing power consumption while maintaining reliable wake-up signal reception.
2Duration of action of stationary object
If the receiving circuit is activated in predetermined time intervals, then battery life is extended, but the ability to receive wake-up signals immediately may be compromised
Solution Approach 1:
The receiving circuit is activated at regular intervals with a predetermined activation period that is carefully selected to be sufficient for receiving wake-up signals. This periodic activation ensures the circuit remains functional for reliable communication while spending most time in low-power sleep mode, thereby extending battery life.
Solution Approach 2:
The system adjusts the activation period parameter to optimize the balance between battery life and reception reliability. By changing this temporal parameter, the system can adapt to different operational requirements while maintaining both extended battery duration and reliable wake-up signal reception capability.
