Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mobile terminal continuously monitors and displays battery information and charging status, then the user can real-time monitor battery status, but the power consumption increases
Solution Approach 1:
The system uses a timer to periodically trigger the battery information acquisition and display update process. Instead of continuous monitoring, the terminal only refreshes battery status information at specific time intervals, reducing CPU wake-up frequency and power consumption while maintaining adequate monitoring capability.
Solution Approach 2:
The system automatically determines whether to enter sleep mode based on battery level thresholds without requiring continuous user intervention. The processor autonomously manages the transition between active and sleep states based on predefined battery level conditions, optimizing power usage while maintaining battery status awareness.
2Reliability
If the processor frequently wakes up to check battery levels and update displays, then the battery status is accurately tracked, but the sleep duration is reduced and power saving is diminished
Solution Approach 1:
The system pre-sets battery level thresholds (first threshold and second threshold) before entering sleep mode. These thresholds are determined in advance based on power saving requirements, allowing the processor to enter sleep mode confidently without frequent wake-ups, as the thresholds have already been established to cover the expected battery depletion scenario.
Solution Approach 2:
The timer creates periodic wake-up intervals that are optimized to balance monitoring accuracy with sleep duration. The system wakes up at predetermined intervals to check battery levels and update the display, rather than waking up continuously or based on interrupt-driven events, thereby maximizing sleep duration while maintaining adequate tracking.
3Use of energy by moving object
If the terminal enters sleep mode to save power, then power consumption is reduced, but the real-time monitoring capability is compromised
Solution Approach 1:
The system implements a periodic monitoring mechanism where the terminal enters sleep mode between monitoring cycles and wakes up at predetermined intervals to check battery status and update the display. This periodic operation maintains adequate monitoring capability while maximizing power savings during sleep intervals.
Solution Approach 2:
The timer acts as an intermediary that coordinates between the sleep mode and monitoring functions. It triggers wake-up events at appropriate intervals, mediating between the conflicting requirements of power saving and real-time monitoring, allowing the system to transition smoothly between active and sleep states based on timing rather than continuous processing.
