Innovation Solution
A simplified project assembly using a combination of LEDs, image-forming units, and refractive lenses that can be easily installed into various outdoor lighting housings, featuring a rotatable disc with multiple optics-lens and image-forming units, allowing for adjustable focus, angle, and moving effects without the need for complex mechanical designs or high heat sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If high heat sources are used for outdoor lighting, then illumination intensity is improved, but heat generation and signal interference worsen
Solution Approach 1:
The patent transitions from high heat generating light sources to LED technology, fundamentally changing the operational parameters of the lighting system. LEDs provide sufficient illumination intensity while operating at much lower temperatures, thereby eliminating heat-related problems and signal interference issues that plague traditional high-intensity lighting systems.
Solution Approach 2:
The patent replaces complex mechanical projection systems with a simplified optical approach using refractive lenses. Instead of using mechanical moving parts to create images, the system uses purely optical elements (refractive lenses) to project patterns, eliminating the need for complex mechanics while maintaining image projection capability.
2Manufacturing precision
If complex optics and multiple components are used for image projection, then image quality is improved, but device complexity and manufacturing difficulty worsen
Solution Approach 1:
The patent extracts and eliminates unnecessary complex components from traditional projection systems. By using a simple refractive lens directly coupled with the LED light source, the design removes the need for complex optical assemblies, mirrors, and multiple moving parts, thereby simplifying the device while maintaining image projection quality.
Solution Approach 2:
The patent merges the light source and optical elements into a single integrated assembly. The LED and refractive lens are positioned in direct proximity, forming a unified projection unit that simplifies manufacturing and assembly. This integration eliminates the need for separate complex optical trains and reduces the number of alignment requirements.
3Area of stationary object
If traditional outdoor lighting designs are used, then illumination coverage is improved, but adaptability to different housing types worsens
Solution Approach 1:
The patent creates a universal lighting module that can be adapted to various housing types and mounting configurations. The simplified projection assembly with LED and refractive lens can be integrated into different outdoor lighting fixtures, landscape lights, and architectural lighting applications, providing both wide illumination coverage and high adaptability to diverse housing designs.
