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

VSEngineering 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

Engineering Contradiction:
Improveinformation offering capabilityVSAvoidpower consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

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

Inventive Principle:
Principle #15Dynamics

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

Inventive Principle:
Principle #35Parameter changes

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

Engineering Contradiction:
Improvebattery lifeVSAvoiddisplay performance
Core Design Contradiction:
Duration of action of moving objectVSReliability

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

Inventive Principle:
Principle #3Local quality

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

Inventive Principle:
Principle #23Feedback
