Solution Overview
Problem
Traditional laser spot lights lack a twinkling effect, leading to visual fatigue due to static or rotating raster images without dynamic illumination.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional laser spot lights use fixed raster images or rotating disks with motor driving, then the device can project changing images, but the device lacks twinkling effect and causes visual fatigue
Solution Approach 1:
The patent applies the dynamics principle by making the light baffle rotatable to dynamically block and unblock laser beams, creating twinkling effects. The light baffle rotates around a rotation axis, alternately blocking and allowing laser beams to pass through, transforming the static image projection into dynamic twinkling light spots that mimic natural star behavior and reduce visual fatigue.
Solution Approach 2:
The patent implements periodic action through the rotational movement of the light baffle, which repeatedly blocks and unblocks laser beams in a cyclic manner. This periodic blocking and unblocking creates the twinkling effect, where light spots appear and disappear rhythmically, similar to the natural twinkling of stars, thereby eliminating visual fatigue while maintaining image projection capability.
2Adaptability or versatility
If traditional laser spot lights use motor driving gear boxes to rotate disks, then the device can change projected images cyclically, but the device structure becomes complex
Solution Approach 1:
The patent applies the extraction principle by removing the complex motor driving gear box mechanism from the traditional disk rotation system. Instead of using a motor to rotate a disk with multiple raster images, the patent extracts the essential function and implements it through a simpler rotating light baffle that blocks and unblocks laser beams, significantly reducing mechanical complexity while maintaining image projection capability.
Solution Approach 2:
The patent inverts the traditional approach by instead of rotating the entire disk with images, it keeps the laser source stationary and rotates only the light baffle to control beam passage. This inversion simplifies the mechanism by eliminating the need for complex gear boxes and motors, achieving image projection through a much simpler rotational blocking mechanism.
3Stability of the object's composition
If traditional laser spot lights use static or rotating raster images, then the device can provide steady illumination, but the device lacks dynamic illumination and causes visual fatigue
Solution Approach 1:
The patent applies dynamics by transforming the static illumination into dynamic twinkling light spots through the rotation of the light baffle. The rotating baffle creates alternating blocks and unblocks of laser beams, producing dynamic illumination patterns that mimic natural star twinkling, thereby maintaining illumination stability while eliminating visual fatigue caused by static or uniformly rotating images.
