Projection Device Dynamic Meteor Effect via Rotating Light Transmitter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing starry sky projection lamps produce static patterns, resulting in a simplistic ambiance, failing to provide a dynamic and engaging visual experience.
Innovation Solution
A projection device comprising a first light-emitting component with a light-emitting member, a light-transmitting member, and a driving member, which generates a linear light band that intersects with the light-transmitting member to create moving star-like spots, simulating a meteor effect by allowing relative motion between the components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a static light-emitting structure is used, then the device is simple in structure, but the projection effect is simplex and lacks dynamism
Solution Approach 1:
The patent applies the dynamics principle by introducing a rotating light-transmitting member that can rotate around the light-emitting member. This rotation transforms the static light pattern into a dynamic one, creating moving star-like spots and meteor-like effects on the ceiling. The light-transmitting member has light-transmitting regions and light-shading regions that, when rotated, produce varying projection patterns, thereby resolving the contradiction between structural simplicity and projection effect diversity.
2Adaptability or versatility
If a rotating light-transmitting member is added to create dynamic effects, then the projection effect becomes dynamic and engaging, but the device structure becomes more complex
Solution Approach 1:
The patent merges the light source function and the light modulation function into a single integrated structure. The light-emitting member and light-transmitting member are combined such that the light-transmitting member rotates around the light-emitting member, eliminating the need for separate complex control systems. This merging approach achieves dynamic projection effects while keeping the overall structure relatively simple and easy to manufacture.
