Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the system enters low power consumption mode to limit processor usage and network activities, then power consumption is reduced, but background applications still consume system resources and periodically wake up the system, leading to suboptimal power-saving results
Solution Approach 1:
The system collects battery statistic data that records wake-up events and analyzes this feedback information to identify unexpected wake-ups. Based on the analysis results, the system dynamically adjusts the status of background applications, creating a closed-loop control mechanism that continuously optimizes power saving effectiveness.
Solution Approach 2:
The patent dynamically adjusts the status of background applications based on real-time battery data analysis. Instead of static power management, the system adapts its behavior by modifying application states according to observed wake-up patterns, enabling optimal power saving that responds to actual system conditions.
2Ease of operation
If background applications are allowed to operate in the background, then user experience is maintained, but system resources are consumed and power saving is compromised
Solution Approach 1:
The system applies different power management strategies to different background applications based on their individual characteristics and wake-up patterns. By analyzing battery statistic data, the system identifies which applications cause unexpected wake-ups and applies selective suspension or status adjustment only to those applications, while maintaining normal operation of well-behaved applications.
