Rotating Inner Cover for Flowing Silhouette Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing festive atmosphere decorative lighting devices are limited in their ability to provide rich and varied decorative effects, often relying on static patterns or simple light projection, which restricts their expressive potential.
Innovation Solution
A decorative lighting device featuring a lamp base with an LED bulb, a spinning component assembly driven by a motor and gear reduction system, and a transparent spherical lamp shade with a colored, frosted internal surface, allowing the inner cover with cutout patterns to spin and project a flowing, vivid silhouette when lit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a static lamp shade with patterns is used, then the structure is simple, but the decorative expression is limited to a single shadow projection
Solution Approach 1:
The patent applies the dynamics principle by transforming the static lamp shade into a rotating inner cover assembly. The inner cover with cutout patterns rotates around the LED bulb, dynamically changing the shadow projection patterns over time. This allows a single device to produce multiple decorative expressions without requiring multiple static lamp shades, thus resolving the contradiction between structural simplicity and decorative versatility.
2Illumination intensity
If a glass or plastic globe is used, then the device is decorative, but the types of displays are limited
Solution Approach 1:
The patent applies segmentation by dividing the single globe structure into multiple functional layers: an inner cover with cutout patterns, a transparent lamp shade with frosted sections, and an LED bulb assembly. Each layer contributes differently to the light projection, creating multiple display types (colored projections, frosted diffusion, cutout silhouettes) from a single integrated device, thus resolving the contradiction between decorative effect and display variety.
3Adaptability or versatility
If the inner cover spins, then the decorative effect is enhanced with flowing silhouette, but the device complexity increases
Solution Approach 1:
The patent applies mechanics substitution by replacing a complex mechanical spinning mechanism with a simple motor-driven rotation system. The motor mounted on the lamp base directly drives the inner cover rotation through a simple transmission, eliminating the need for complex gears, belts, or manual operation mechanisms. This resolves the contradiction by achieving rich decorative effects through spinning while keeping the mechanical system simple and reliable.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device offers enhanced decorative lighting effects with a rich, flowing silhouette that enhances the visual appeal and versatility, allowing for different patterns and improved clarity through the use of a spherical shape and frosted glass, while being easy to assemble and maintain.
Implementation Method 1
an LED bulb set inside the lamp base... The LED bulb sits inside the lamp base above the mounting base, the LED bulb being mounted on an outer extent of an output shaft of the gear reduction configuration. Rotation of the output shaft of the gear reduction configuration causes rotation of the mounting base and, in turn, rotation of the inner cover.
Implementation Method 2
a transparent spherical lamp shade with a colored, frosted internal surface, allowing the inner cover with cutout patterns to spin and project a flowing, vivid silhouette when lit

AI summary
A festive atmosphere decorative lighting device which includes a lamp base, an LED bulb set inside the lamp base and an electrical switch for the bulb. A spinning assembly housed in the lamp base has an output shaft which is connected to an inner cover for spinning the inner cover. The inner cover fits over the LED bulb and has a cutout pattern of holes. The lamp base is also fitted with a transparent lamp shade which is superimposed above the inner cover. When the LED bulb is switched on and the spinning configuration spins the inner cover, light emitted by the LED bulb passes through the holes in the inner cover and presents a flowing vivid silhouette, as observed by a viewer.
