Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional lighting control methods are used in media content playback environments, then the implementation is simple, but the feeling of immersion is insufficient
Solution Approach 1:
The patent transitions from traditional 2D screen-based lighting control to 3D spatial environment mapping. By dividing the 3D environment into multiple regions and assigning color attributes to each region based on depth information, the system creates immersive lighting effects that correspond to the spatial layout of the media content, thereby enhancing the feeling of immersion through dimensional expansion.
Solution Approach 2:
The patent segments the 3D environment into multiple discrete regions based on depth information and spatial coordinates. Each region can be independently controlled with specific color attributes, allowing precise lighting control for different parts of the environment. This segmentation enables complex immersive effects while maintaining manageable control through region-based organization.
2Reliability
If 3D environment lighting control with region division is implemented, then the feeling of immersion is enhanced, but the data processing and control complexity increases
Solution Approach 1:
The patent introduces an intermediary processing system that automatically maps 3D environment data to lighting control parameters. The system uses depth information and spatial coordinates as intermediaries to translate media content spatial layout into region-specific color attributes, simplifying the operation by automating the complex mapping process between 3D environment and lighting devices.
Solution Approach 2:
The patent performs preliminary division of the 3D environment into regions and pre-assignment of color attributes to each region based on depth information. This preliminary action prepares the lighting control structure in advance, so that during actual playback, the system only needs to retrieve and apply pre-defined region color attributes, significantly simplifying real-time operation and control.
3Measurement precision
If dynamic lighting control based on device position in 3D environment is implemented, then the lighting precision is improved, but the computational requirements increase
Solution Approach 1:
The patent applies local quality by assigning specific color attributes to specific 3D regions based on the lighting device's position and orientation. Instead of uniformly controlling all lighting devices, the system determines which region each device should illuminate and applies localized color control, improving lighting precision while reducing computational requirements by focusing processing only on relevant local areas.
Solution Approach 2:
The patent extracts only the necessary position and orientation data of lighting devices from the full 3D environment information. By taking out and processing only the relevant spatial parameters needed for region-color matching, the system achieves precise lighting control without the computational burden of processing complete environmental data.
