Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current LED bulb technologies face challenges in creating a moving projection image with wide viewing angles and efficient illumination, as they often suffer from heat issues, electrical signal interference, and limited illumination range due to blockages from lamp shades or other objects.
Innovation Solution
The integration of a moving LED bulb system with a rotating optics-lens assembly, image carrier, and adjustable light beams, utilizing a gearbox for controlled rotation speed, allows for a wide viewing angle projection image while overcoming heat and signal interference by repositioning LEDs and electric components to avoid blockages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If LED bulbs are used for projection, then energy efficiency is improved, but heat generation causes signal interference and blockage issues
Solution Approach 1:
The patent extracts the harmful heat generation effect from the LED bulb by positioning it outside the projection path and using a separate illumination source (lamp shade) for the projection mechanism. This separation removes the heat interference while maintaining LED energy efficiency for ambient lighting.
Solution Approach 2:
The patent introduces an intermediary illumination system (lamp shade with projection patterns) that mediates between the LED light source and the projection surface. This intermediary carries the projection function while allowing LED bulbs to operate independently without heat-related signal interference.
2Illumination intensity
If lamp shades are used for projection, then image projection is achieved, but viewing angle is limited
Solution Approach 1:
The patent applies dynamics by making the projection system rotatable, allowing the projection image to move and be viewed from different angles. The rotating mechanism enables the same projection source to serve multiple viewing positions dynamically.
Solution Approach 2:
The patent adds rotational movement as another dimension to the projection system, transforming a static single-angle projection into a dynamic multi-angle projection capability, effectively increasing viewing angle coverage.
3Device complexity
If LEDs are positioned close to projection components, then compact design is achieved, but electrical signal interference occurs
Solution Approach 1:
The patent extracts the LED bulbs from close proximity to the projection components, positioning them separately to eliminate electrical signal interference while maintaining a relatively compact overall design through strategic spatial arrangement.
