Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with high-resolution displays consume more electric current, leading to increased power consumption and resource usage, which can hinder efficient operation.
Innovation Solution
A method and device that adjust the display resolution based on the system load of the electronic device, reducing electric current consumption and resource usage by dynamically changing the screen resolution when high power consumption or resource load is detected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high resolution display is installed in electronic device, then display quality is improved, but electric current consumption increases
Solution Approach 1:
The patent applies dynamics by making the display resolution adjustable rather than fixed. The system dynamically changes resolution between high and low based on system load conditions, allowing the display quality and energy consumption to adapt to different operational states. This resolves the contradiction by enabling the display to provide high quality when needed while consuming less energy during normal operations.
Solution Approach 2:
The patent changes the resolution parameter of the display based on system load detection. When system load exceeds a threshold, the resolution is reduced from high to low, directly changing this physical parameter to reduce frame buffer size and electric current consumption while maintaining adequate display functionality.
2Measurement precision
If high resolution display is installed in electronic device, then display quality is improved, but resource use increases
Solution Approach 1:
The system dynamically adjusts the amount of memory resources allocated to the display frame buffer based on system load. By switching between high and low resolution, the system optimizes resource utilization, allocating more memory to frame buffer only when high display quality is required, rather than permanently allocating large memory resources.
Solution Approach 2:
The patent changes the resolution parameter to control frame buffer size, directly impacting memory resource usage. When resolution is reduced to low, the frame buffer size decreases accordingly, reducing the quantity of memory resources consumed by the display system.
3Use of energy by moving object
If resolution is reduced to low, then electric current consumption is reduced, but display quality deteriorates
Solution Approach 1:
The system periodically monitors system load and adjusts resolution accordingly. Rather than maintaining constantly low resolution, the system switches to high resolution when system load is low and adequate processing power is available, providing periodic high-quality display output while maintaining low energy consumption during high-load periods.
Solution Approach 2:
The display resolution is made dynamic, switching between low and high based on real-time system conditions. This ensures that low resolution (and low energy consumption) is maintained during normal operations, while high resolution is activated when system resources are abundant, optimizing the trade-off between energy efficiency and display quality.

AI summary
A method for adjusting the resolution of an electronic device may comprise the operations of changing resolution of a screen, which is displayed through a display functionally connected to the electronic device, when a load of a system resource is sensed, and displaying the screen through the display on the basis of an image having the changed resolution
