Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the same image quality enhancing algorithm and power consumption reduction algorithm are applied to all regions in split window technology, then device complexity is reduced and ease of operation is improved, but image quality enhancement is suboptimal and power consumption reduction is limited
Solution Approach 1:
The patent divides the display screen into multiple independent regions (first region and second region) and applies different image quality enhancing algorithms and power consumption reduction algorithms to each region. This segmentation allows optimized control for different content types (e.g., video playback in one region, image viewing in another) without requiring a complete system redesign, thus improving power consumption reduction efficiency while maintaining reasonable ease of operation through modular algorithm selection.
Solution Approach 2:
The patent implements region-specific algorithm selection where each divided region can have tailored image quality enhancement and power consumption reduction parameters. For example, one region may use aggressive power reduction for static images while another maintains high image quality for video content. This local quality approach optimizes the balance between image quality enhancement and power consumption reduction for diverse display scenarios.
2Use of energy by moving object
If region-specific image quality enhancing algorithms and power consumption reduction algorithms are applied in split window technology, then image quality enhancement is optimized and power consumption reduction is improved, but device complexity increases
Solution Approach 1:
The patent segments the display into multiple regions and assigns different algorithms to each, which optimizes power consumption and image quality. The complexity increase is managed by providing a user interface that allows straightforward selection of algorithms per region without requiring users to understand the underlying technical complexity. The system automatically handles the coordination between regions, masking the complexity from the user while delivering optimized performance.
Solution Approach 2:
The patent implements dynamic algorithm selection and parameter adjustment for each region based on content type, user preferences, and power consumption requirements. The system can dynamically switch between different algorithm combinations and adjust parameters in real-time, providing optimized performance for varying display scenarios. This dynamic approach manages complexity by automating adjustments rather than requiring fixed, overly complex configuration systems.
3Device complexity
If uniform power consumption reduction algorithms are applied to all regions, then device complexity is minimized, but power consumption reduction efficiency is suboptimal for different content types in split windows
Solution Approach 1:
The patent divides the display into multiple regions and applies different power consumption reduction algorithms to each region based on content type. For example, video playback regions may use algorithms optimized for motion compensation while image viewing regions use different algorithms. This segmentation improves power consumption optimization efficiency without requiring a complete redesign of the control system, as each region can be independently optimized while sharing common infrastructure.
Solution Approach 2:
The patent implements region-specific parameter adjustments for power consumption reduction algorithms, allowing different luminance reduction levels, refresh rate adjustments, and processing intensity settings for each region. This parameter customization enables optimized power consumption for diverse content types while maintaining a unified algorithm framework, thus improving energy efficiency without proportionally increasing control system complexity.
