Rotating Eccentric Light Source for Dynamic Projection Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projection lamps have static light sources and films, limiting them to project only static patterns, which fail to attract attention effectively and provide a poor display effect.
Innovation Solution
A projection lamp design featuring a rotating lamp holder with a light source positioned eccentrically, driven by a motor, and a film between the light source and a light-transmitting sheet, allowing for dynamic pattern projection with changing light intensity and improved display effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a static light source and film are used in the projection lamp, then the structure is simple and stable, but the projection pattern is single and has no diversity
Solution Approach 1:
The patent applies the dynamics principle by making the light source rotate around the central axis of the lamp holder through a driving component. This rotation causes the light source to pass through different positions relative to the film, enabling dynamic projection patterns that change over time. The static structure is transformed into a dynamic system that can project diverse patterns while maintaining structural simplicity.
2Adaptability or versatility
If a static light source is positioned at the center of the lamp holder, then the structure is simple and stable, but only static patterns can be projected
Solution Approach 1:
The patent applies the asymmetry principle by positioning the light source away from the central axis of the lamp holder. This asymmetric positioning, combined with rotational movement, allows the light source to create varied projection patterns by passing through different spatial relationships with the film. The asymmetric arrangement enables pattern diversity without requiring complex positioning mechanisms.
3Adaptability or versatility
If the light source rotates around the central axis, then dynamic projection patterns are achieved, but the light intensity may become uneven
Solution Approach 1:
The patent applies the intermediary principle by introducing the film as a mediator between the rotating light source and the projection surface. The film, positioned between the light source and the projection surface, helps to distribute and uniformize the light intensity. This intermediary element ensures that even as the light source rotates and changes position, the projected patterns maintain relatively uniform illumination while still displaying dynamic characteristics.
