Solution Overview
Problem
Current dynamic projection technologies are either complex and expensive, making them unsuitable for consumer electronics, or they lack the ability to produce animated effects efficiently.
Innovation Solution
A dynamic display projection lamp with a tubular housing, adjustable angle, and a fixing assembly that includes multiple projection units with LEDs, convex lenses, and UV-resistant films, allowing for sequential lighting control to create animated patterns through persistence of vision, which is simple, cost-effective, and easy to maintain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If motor-driven rotation or filmstrip mechanisms are used to achieve dynamic projection, then animated effects can be produced, but the device complexity and cost increase significantly
Solution Approach 1:
The projection system is divided into multiple independent projection units, each projecting a static pattern. By controlling each unit independently through sequential lighting, the system achieves dynamic animation effects without requiring mechanical movement or complex mechanisms. This segmentation allows simple static components to work together to create complex dynamic effects.
Solution Approach 2:
The patent employs periodic switching of light sources in different projection units to create animation effects. By turning light sources on and off in sequence and utilizing the persistence of vision phenomenon, the system produces dynamic patterns without mechanical motion. This periodic control of static elements replaces complex mechanical animation mechanisms.
2Productivity
If multiple light sources are controlled sequentially to create animation effects, then productivity and ease of manufacture improve, but the system requires precise control mechanisms
Solution Approach 1:
Multiple identical projection units share the same structure and components, allowing them to be manufactured using the same processes and assembled in a standardized manner. This universality improves manufacturing productivity and simplifies maintenance, as replacement units can be easily substituted without requiring complex customization or control reconfiguration.

AI summary
A dynamic display projection lamp of the present invention includes plural projection units fixed to a fixing assembly. The fixing assembly includes a lens holder and a film holder for fixing a film. A plurality of penetrating holes are defined in the lens holder, and clamping grooves for clamping plural lenses of plural lens groups are formed in inner walls defining the penetrating holes. The film holder is fixed in the lens holder or at least a portion of the film holder is inserted between the lenses through an opening of the lens holder. All the projection units disposed in a single row or two rows up and down are fixed by using the lens holder and the film holder. The projection units are allowed to project patterns in sequence by using a controller, thus producing a dynamic pattern projection effect.
