Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multi-core CPU, high-performance GPU and LTE module operate simultaneously at full speed, then processing performance and communication capability are improved, but instantaneous power consumption increases causing battery voltage to drop below safe working levels
Solution Approach 1:
The system dynamically adjusts the working states of CPU, GPU, and LTE module based on real-time battery electric quantity detection. When battery electric quantity is sufficient, components operate at high performance; when electric quantity is low, the system automatically reduces working frequencies and disables cores to maintain stable operation.
Solution Approach 2:
The invention changes operational parameters (CPU frequency, GPU acceleration level, LTE data rate) based on battery electric quantity thresholds. Different parameter sets are applied depending on whether battery level is above or below critical thresholds, optimizing both performance and power consumption.
2Productivity
If CPU works at full speed without considering battery electric quantity, then processing efficiency is improved, but battery voltage suddenly decreases causing abnormal restarts and crashes
Solution Approach 1:
The system implements feedback control by continuously detecting battery electric quantity and using this information to adjust CPU working state. The detection unit monitors battery level in real-time and feeds this information to the adjustment unit, which modifies CPU frequency and core activation accordingly to prevent voltage drops and ensure stable operation.
Solution Approach 2:
The system takes preliminary action by detecting battery electric quantity before voltage drop occurs and proactively adjusting CPU working state to prevent abnormal restarts and crashes. The adjustment is made in advance based on predicted power consumption needs versus available battery capacity.
3Productivity
If all working components operate at full load simultaneously, then system performance is maximized, but instantaneous heavy current causes battery voltage to fall below minimum safe working voltage
Solution Approach 1:
The system applies partial action by selectively enabling only necessary CPU cores and adjusting GPU and LTE operation levels based on actual workload requirements and battery status. Instead of always running all components at maximum capacity, the system uses just enough processing power needed while maintaining stability margins.
