Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing starry sky projection lamps lack a dynamic and combined effect of nebula, with only dot-shaped starry sky effects and static displays, failing to provide an immersive experience.
Innovation Solution
A lamp design incorporating a lamp frame, first light source, optical integrating lenses, roller beam splitter, starry sky laser assembly, and starry sky mirror disc, which focuses light into strip-shaped spots and combines them with light dots to simulate a dynamic nebula effect, creating a dynamic starry sky display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional dot-shaped starry sky projection is used, then the structure is simple, but the visual effect is static and lacks nebula simulation capability
Solution Approach 1:
The patent divides the optical system into separate functional modules: a first light source with optical integrating lens for generating strip-shaped light spots (simulating nebula), and a second light source (laser assembly) for generating light dots (simulating stars). This segmentation allows each module to specialize in creating specific visual effects, thereby increasing visual effect variety while keeping each individual module relatively simple.
Solution Approach 2:
The patent combines multiple light sources and optical components into a single lamp device. The first light source system (for nebula effect) and the second light source (laser assembly for stars) are integrated within the same lamp frame, allowing simultaneous projection of both strip-shaped light spots and light dots to create a combined starry sky with nebula effect.
2Ease of operation
If a static starry sky display is used, then the device structure is simple, but the user experience and immersion are insufficient
Solution Approach 1:
The patent introduces dynamic elements to the starry sky display. The laser assembly includes a rotating mirror disc that can rotate to dynamically change the positions and patterns of light dots projected on the ceiling. Additionally, the control system can independently control the brightness and operation of the first and second light sources, enabling dynamic transitions between different visual effects and enhancing user experience.
3Adaptability or versatility
If only dot-shaped light spots are projected, then the optical system is simple, but the nebula effect cannot be simulated
Solution Approach 1:
The patent applies different optical properties to different parts of the system. The first light source uses an optical integrating lens with specific optical properties to transform point light into extended strip-shaped light spots, while the second light source (laser) maintains its point-like light dots. This local differentiation of optical qualities enables both nebula (strip-shaped) and star (dot-shaped) effects to be simulated simultaneously.

Function Achieved in This Case
The solution achieves a dynamic and immersive starry sky effect, simulating stars and nebulae, enhancing user experience with a beautiful and realistic galactic nebula representation.
Implementation Method 1
