Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a blue light guide panel is used to create an artificial sky component, then the device can generate sky light, but the realism of the sky scene is insufficient
Solution Approach 1:
The sky scene is divided into multiple independent components: diffuse sky light component, collimated sunlight component, and distant object component. Each component is generated by separate optical systems (diffuse light generation system with redirecting members, collimated light generation system, and light control members respectively), allowing independent optimization of each element to achieve overall realism.
Solution Approach 2:
Multiple light generation systems are combined within a single device: the diffuse light generation system, collimated light generation system, and distant object generation system work together to create a comprehensive sky scene that includes both sky background and distant objects, achieving enhanced realism through integration.
2Illumination intensity
If existing artificial sky light devices are used, then sky light can be generated, but distant depth perception is not achieved
Solution Approach 1:
The device transitions from a two-dimensional light emission surface to a three-dimensional optical arrangement by introducing light control members at different depths. This creates the perception of distant objects at optical infinity through the third dimension, enabling distant depth perception while maintaining sky light generation capabilities.
Solution Approach 2:
Light control members are introduced as intermediary elements between the light sources and the observer. These members manipulate light paths to create the perception of distant objects, acting as mediators that transform the physical light generation into perceived distant depth without requiring actual physical depth.
3Illumination intensity
If existing artificial sky light devices are used, then sky light can be generated, but dynamic cloud movements are not simulated
Solution Approach 1:
The light control members are configured to be adjustable or reconfigurable, enabling the device to simulate dynamic cloud movements. The system can adapt its light control member arrangement to create different cloud patterns and motions, transforming a static sky light generator into a dynamic simulation device.
