Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the processor and display operate at high performance continuously, then the performance and user experience are improved, but the power consumption increases unnecessarily
Solution Approach 1:
The patent implements dynamic mode switching between first mode (lower power consumption) and second mode (higher performance) based on real-time detection of image classes. The system transitions from static performance levels to dynamic adjustment, allowing the processor and display to operate at different performance tiers depending on usage conditions, thereby resolving the contradiction between continuous high performance and unnecessary power consumption
Solution Approach 2:
The system changes operational parameters (performance level) based on detected image classes. When predetermined image classes are detected, the system switches to high performance mode; otherwise, it operates in low power mode. This parameter adjustment allows the system to optimize the balance between performance and power consumption based on actual usage patterns
2Power
If the device operates in high performance mode continuously, then the performance is maintained, but the battery life is reduced
Solution Approach 1:
The system dynamically adjusts performance levels based on real-time image class detection, transitioning between high performance mode (when needed) and low power mode (when not needed). This dynamic approach extends battery life by preventing continuous high-performance operation while maintaining performance when users need it, thus resolving the contradiction between performance maintenance and battery life
Solution Approach 2:
The system uses feedback from image class detection to control performance mode switching. The detection results provide feedback that triggers mode transitions, ensuring the system operates at appropriate performance levels based on actual usage conditions, thereby extending battery life without compromising performance when needed
3Use of energy by moving object
If the device switches between multiple modes, then the power consumption efficiency is improved, but the device complexity increases
Solution Approach 1:
The patent implements multi-functionality by integrating image class detection, mode switching, and performance adjustment into a unified control system. The same detection mechanism serves multiple purposes: identifying usage conditions, triggering mode transitions, and optimizing performance. This universal approach improves power consumption efficiency while minimizing the increase in device complexity through functional integration

AI summary
A power consumption control device applied to an electronic device includes an image signal processor (ISP), a storage device, a processing circuit, and a control circuit. The ISP is arranged to receive an image signal captured by a camera of the electronic device, and process the image signal to generate a processed image signal. The storage device is arranged to store at least one predetermined image class. The processing circuit is arranged to analyze the processed image signal to detect whether the processed image signal belongs to the at least one predetermined image class to generate a control signal. The control circuit is arranged to switch a mode of the electronic device to a first mode or a second mode according to the control signal, wherein power consumption and performance of the electronic device in the first mode are lower than that in the second mode.
