Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If conventional automatic brightness adjustment is used, then energy consumption is reduced, but user immersion in video content is insufficient
Solution Approach 1:
The patent divides the display screen into multiple regions (e.g., sky region, ground region, water region) and assigns different lighting colors to different regions. For example, the sky region may display blue light while the ground region displays green light, creating a localized lighting effect that enhances immersion without requiring full-screen uniform lighting, thus optimizing energy consumption.
Solution Approach 2:
The lighting system is segmented into multiple independent light sources that can be controlled separately. Each light source corresponds to a specific region of the display and can be adjusted independently based on the content displayed in that region, allowing for selective lighting activation that reduces overall energy consumption while maintaining immersion.
2Adaptability or versatility
If multiple lighting devices are used to enhance immersion, then user immersion is improved, but device complexity increases
Solution Approach 1:
The lighting module is designed to serve multiple functions: it can display different colors for different regions, adjust brightness based on ambient light conditions, and synchronize with video content. This multi-functionality allows a single lighting system to achieve complex immersion effects without requiring multiple separate devices.
Solution Approach 2:
The patent combines the lighting control functionality with the existing display system and ambient light sensor. The processor integrates information from the display content, ambient light conditions, and user preferences to control the lighting module, merging multiple control functions into a unified system that reduces overall complexity.
3Adaptability or versatility
If lighting is adjusted to match image content, then user immersion is enhanced, but processing complexity increases
Solution Approach 1:
The system pre-divides the display screen into multiple regions and pre-assigns lighting characteristics to each region. This preliminary segmentation allows the processing to focus on identifying which regions are active in the current video frame rather than analyzing the entire screen, reducing real-time processing complexity while maintaining immersion quality.
Solution Approach 2:
The system processes only the necessary portions of the video content to determine lighting parameters. Instead of analyzing every pixel, it samples key regions and uses this partial information to control the lighting, achieving sufficient immersion effect with reduced processing complexity.
