Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current indoor lighting devices that simulate sunlight lack the ability to dynamically adjust the position of the simulated sun and radiation area according to user-intended times or trajectories, limiting user experience and environmental simulation.
Innovation Solution
A lighting device comprising multiple lighting units with different illuminance and color settings, including a first unit for simulating the sky, a second unit for simulating shadows, and a third unit for simulating the sun, with adjustable positioning and color gradation to mimic outdoor environments, using a diffusion plate and inclined surfaces to distribute light effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple lighting units with different illuminance and color settings are used to simulate various outdoor environments, then the simulation effect and user experience are improved, but the device complexity increases
Solution Approach 1:
The lighting device is divided into multiple independent lighting units (first lighting unit for sky simulation, second lighting unit for shadow simulation, third lighting unit for sun simulation), each with different illuminance and color settings. This segmentation allows each unit to independently control specific environmental elements, achieving comprehensive outdoor simulation while maintaining manageable system complexity through modular design.
2Adaptability or versatility
If the second lighting unit is arranged on an inclined surface surrounding the first lighting unit, then the shadow simulation effect is improved, but the device structure becomes more complex
Solution Approach 1:
The second lighting unit is arranged on an inclined surface that surrounds the first lighting unit, transitioning from a conventional planar arrangement to a three-dimensional spatial configuration. This dimensional change enables the creation of realistic shadow effects by positioning light sources at various angles and heights, achieving superior shadow simulation while the inclined surface design integrates the complexity into an aesthetically pleasing form factor.
3Adaptability or versatility
If the third lighting unit is positioned to provide higher illuminance through openings in the first lighting unit, then the sun simulation effect is improved, but the lighting control complexity increases
Solution Approach 1:
The third lighting unit is strategically positioned to provide high illuminance only through specific openings in the first lighting unit, rather than uniformly across the entire device. This local quality approach concentrates the intense sunlight simulation effect precisely where needed (through the openings representing the sun's position) while keeping other areas at appropriate ambient levels, achieving realistic sun simulation with manageable control complexity.
