Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If real environments are mapped to extended reality space without virtual light sources, then the system complexity is reduced, but the ability to render realistic lighting effects and provide personalized display is lost
Solution Approach 1:
The patent creates virtual light sources that replicate and simulate real lighting conditions in the extended reality space. Instead of requiring physical light sources or complex optical systems, the system copies the essential lighting properties (intensity, color temperature, direction) into the virtual environment, enabling realistic rendering without adding physical complexity
Solution Approach 2:
The patent enables dynamic adjustment of light source parameters (such as intensity, color temperature, position) in the extended reality space. By changing these parameters, the system can render different lighting scenarios and provide personalized display options without requiring physical reconfiguration of the environment
2Adaptability or versatility
If virtual light sources with customizable parameters are added to extended reality space, then personalized lighting simulation is achieved, but the device complexity increases
Solution Approach 1:
The virtual light source system is designed to perform multiple functions: it can simulate different lighting conditions (natural light, artificial light, twilight), support various applications (furniture selection, virtual photography, interior design), and adapt to different user preferences. This multi-functionality is achieved through a unified virtual light source framework that handles diverse lighting scenarios without requiring separate systems for each application
Solution Approach 2:
The system copies essential lighting properties from real-world scenarios into the virtual environment, creating simplified representations that capture the key characteristics of different lighting conditions. This allows the system to provide realistic lighting simulation using lightweight virtual models rather than complex physical systems
