Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices that project colorful light patterns or moving images often fail to provide effective tabletop illumination while maintaining sufficient translucent properties and preventing light from casting onto unwanted surfaces.
Innovation Solution
A lighting device with a projectable light base and a hollow spherical cover made of translucent material, which heavily diffuses LED light beams to create a soft, colorful light pattern or design, and can be securely attached or detached to control where the light is projected, using a locking mechanism and motorized components for motion effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a translucent cover is used to allow light transmission, then illumination to an area is provided, but light patterns are not sufficiently contained and may cast onto unwanted surfaces
Solution Approach 1:
The patent employs a translucent spherical cover that acts as a flexible optical boundary, containing light within the device while still allowing diffuse transmission. The spherical geometry and translucent material create a balance between illuminating the surrounding area and preventing light from projecting onto walls or ceilings, effectively using a thin film structure to control light behavior.
2Adaptability or versatility
If optical elements are added to project light patterns, then colorful light patterns and moving images are created, but the device complexity increases
Solution Approach 1:
The spherical cover serves multiple functions simultaneously: it diffuses light for ambient illumination, contains light to prevent projection onto walls, and works with the LED array to create colorful light patterns. This multi-functional design achieves versatile lighting capabilities without proportionally increasing device complexity, as the same structural element performs multiple optical functions.
3Illumination intensity
If the cover is made heavily diffusing, then soft ambient light is achieved, but translucent properties are reduced
Solution Approach 1:
The patent utilizes the specific parameter of spherical geometry combined with translucent material properties to achieve optimal light diffusion. The spherical shape and material selection create a balance where sufficient diffusion for soft ambient light is achieved while maintaining adequate translucency for light transmission, effectively optimizing the physical parameters of the cover.
