Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing artificial sky simulation technologies are costly due to the use of nano-diffusers and Rayleigh scattering panels, require significant space for atmospheric layer formation, and are limited to simulating clear skies with sunlight, failing to replicate various weather conditions and atmospheric environments.
Innovation Solution
An artificial sky simulation apparatus using a transparent organic light-emitting diode (TOLED) display and a directional light source with a reflective mirror to simulate natural light and shadows, along with a control unit to adjust brightness, color temperature, and position of the light source, allowing simulation of various weather conditions and atmospheric environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If nano-diffuser and Rayleigh scattering panel are used to simulate atmospheric layer, then the simulation realism improves, but the cost increases significantly
Solution Approach 1:
Instead of using expensive nano-diffuser and Rayleigh scattering panels to physically simulate atmospheric scattering, the system uses a transparent display to copy and render the visual appearance of the sky. This digital copying approach achieves similar visual realism at much lower cost by displaying sky images rather than physically replicating atmospheric optical effects.
Solution Approach 2:
The patent replaces the mechanical/optical system of nano-diffusers and scattering panels with an electronic display system. The transparent display uses electronic image rendering to simulate sky appearance, substituting complex physical optical components with a simpler electronic display technology.
2Manufacturing precision
If a thick space of about 1 m is allocated to form the atmospheric layer, then the simulation accuracy improves, but the space requirement increases
Solution Approach 1:
The patent transitions from a three-dimensional physical atmospheric layer simulation to a two-dimensional display-based simulation. The transparent display renders sky images on a flat surface, eliminating the need for thick spatial volume to simulate atmospheric effects. This dimensional reduction achieves similar visual results with minimal space occupation.
Solution Approach 2:
The system copies the visual appearance of a thick atmospheric layer onto a thin display surface. Rather than physically creating a 1-meter thick atmospheric simulation space, the transparent display reproduces the visual effects of such a layer on a two-dimensional plane, achieving the same visual accuracy with negligible thickness.
3Device complexity
If the simulation apparatus only simulates clear sky with sunlight, then the device complexity remains low, but the adaptability to various weather conditions decreases
Solution Approach 1:
The transparent display enables dynamic switching between different sky images representing various weather conditions. The system can dynamically render clear sky, cloudy sky, rainy sky, and other weather states by changing the displayed image, providing high adaptability without adding complex physical simulation components for each weather type.
Solution Approach 2:
The transparent display serves multiple functions by displaying different sky images for various weather conditions. A single display device replaces what would otherwise require multiple specialized simulation systems for different weather types, achieving multi-functionality and high adaptability while maintaining low device complexity.
