Engineering Contradiction Analysis
1Volume of moving object
If backward illumination is used to provide surround-lighting, then the physical size of the monitor housing is reduced, but the quality of surround-lighting is affected by unpredictable environmental illumination and surface colors
Solution Approach 1:
The patent employs sensors to detect environmental illumination levels and surface reflectivity properties, then feeds this information back to a controller that adjusts the backward illumination intensity accordingly. This feedback mechanism ensures consistent surround-lighting quality despite variations in environmental conditions, resolving the contradiction between compact housing and reliable lighting performance.
Solution Approach 2:
The system dynamically changes the illumination parameters (intensity, color temperature) of the backward lighting based on detected environmental conditions. By adjusting these parameters in real-time, the system maintains consistent surround-lighting quality while using a compact monitor housing design.
2Reliability
If light-sources are arranged around the monitor to provide surround-lighting, then the quality of surround-lighting is improved, but the overall physical size and bulk of the housing increases
Solution Approach 1:
The patent extracts the light generation function from the housing structure itself and places it in a separate backward illumination unit positioned behind the monitor. This allows the monitor housing to remain compact while still providing quality surround-lighting through the extracted illumination unit that can be positioned optimally without increasing the main housing volume.
Solution Approach 2:
The system introduces an intermediary backward illumination unit that acts as a mediator between the compact monitor housing and the requirement for quality surround-lighting. This intermediary unit is positioned behind the monitor and projects light toward the viewer, enabling quality lighting without the housing bulk that would result from integrating light sources around the monitor perimeter.
3Reliability
If the monitor is positioned near a white surface to improve surround-lighting quality, then the quality of reflected light is improved, but the adaptability to different installation locations is reduced
Solution Approach 1:
The system enables the monitor to self-adjust its surround-lighting based on detection of the surrounding environment. The sensors automatically detect the color and reflectivity of nearby surfaces and environmental lighting conditions, then the controller adjusts the backward illumination to compensate, allowing high-quality surround-lighting regardless of installation location without requiring the user to manually configure settings.
Solution Approach 2:
The system dynamically changes the illumination parameters based on detected environmental conditions and surface properties. When installed near surfaces with different colors or reflectivity, the system adjusts the backward lighting parameters to maintain consistent surround-lighting quality, thereby maintaining adaptability to different installation locations while preserving lighting quality.
