Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for adjusting window brightness on electronic devices require system write access, limiting the ability to adaptively adjust application window brightness based on system screen brightness changes, which affects user experience.
Innovation Solution
A method and apparatus that detect changes in system screen brightness without requiring write access, allowing for adaptive adjustment of application window brightness based on a target brightness value, using a computing device to map and adjust window brightness accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If system write access is obtained to adjust window brightness, then brightness adjustment capability is improved, but system security is compromised
Solution Approach 1:
The patent introduces an intermediary mechanism that listens to system brightness change events and automatically adjusts application window brightness accordingly. This mediator approach allows the system to achieve brightness adjustment functionality without requiring applications to obtain direct write access to system parameters, thus maintaining system security while enabling the desired functionality.
2Manufacturing precision
If system write access is required for brightness adjustment, then brightness control precision is improved, but device complexity increases
Solution Approach 1:
The patent implements a self-service mechanism where the system automatically detects brightness changes and triggers appropriate adjustments to application windows. This self-service approach eliminates the need for complex permission management and manual intervention, reducing device complexity while maintaining precise brightness control through automated event-driven adjustments.
3Ease of operation
If manual parameter adjustment is allowed without system write access, then ease of use is improved, but adaptability to system changes deteriorates
Solution Approach 1:
The patent implements a feedback mechanism that continuously monitors system brightness changes and automatically adjusts application window brightness in response. This feedback loop ensures that application windows adaptively respond to system brightness changes without requiring manual user intervention, thereby maintaining both ease of use and adaptability to system changes.
