Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As the number of displays connected to electronic devices increases, so does power consumption, posing a challenge in reducing energy usage while maintaining functionality.
Innovation Solution
The electronic device identifies the number of connected displays and switches between a first and second power consumption mode, adjusting functions such as luminance, touch sensitivity, and CPU core usage to optimize power usage based on the number of displays and their usage patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of displays functionally connected with the electronic device increases, then information offering capability and user convenience are improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic power consumption mode switching based on the number of connected displays. The system automatically transitions between first power consumption mode (for single display) and second power consumption mode (for multiple displays), adjusting resource allocation and display parameters in real-time to optimize energy usage while maintaining functionality
Solution Approach 2:
The patent changes operational parameters including power consumption mode, luminance levels, touch sensitivity, and CPU core allocation based on the number of connected displays. By adjusting these parameters dynamically, the system reduces power consumption in multi-display scenarios while preserving user experience and device functionality
2Duration of action of moving object
If power consumption mode is reduced to save energy, then battery life is extended, but display performance and user experience may be compromised
Solution Approach 1:
The patent applies different power consumption modes and parameter settings to different displays based on their individual usage patterns and importance. Rather than uniformly reducing performance across all displays, the system selectively adjusts parameters for specific displays, maintaining high performance where needed while reducing consumption where possible
Solution Approach 2:
The system continuously monitors the number of connected displays and their usage status, then provides feedback to adjust power consumption modes and parameters accordingly. This closed-loop control ensures that display performance is maintained at appropriate levels while optimizing battery life based on actual usage conditions
