Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional projection systems face difficulties in achieving a uniformly flat boundary surface between areas with and without aerosol diffusion, leading to unclear perception of light beams projected onto mist.
Innovation Solution
A light beam emission system comprising a blower that forms a flow path for aerosol and an emitter that emits a light beam along this path, ensuring the light beam is clearly perceived by diffusing it within the aerosol.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If mist is diffused into the image projection space using a conventional projection system, then the light beam becomes visible through aerosol diffusion, but the boundary surface between areas with and without mist becomes rough and non-uniform, reducing clarity of perception
Solution Approach 1:
The patent introduces a guide member as an intermediary component that structures the aerosol flow path. This guide member creates a defined flow path for the aerosol, ensuring uniform distribution and a flat boundary surface between aerosol and non-aerosol regions, thereby resolving the contradiction between visibility and boundary uniformity
Solution Approach 2:
The patent controls the flow rate of aerosol as a key parameter to achieve optimal visibility while maintaining boundary uniformity. By adjusting the aerosol flow rate and using the guide member to direct the flow, the system achieves clear light beam perception with a uniform boundary surface
2Illumination intensity
If aerosol is used to diffuse light beam, then the light beam can be perceived in bright spaces, but the boundary surface between aerosol and non-aerosol areas becomes rough, affecting image quality
Solution Approach 1:
The guide member acts as an intermediary that mediates between the aerosol source and the projection space, creating a controlled flow path that ensures uniform aerosol distribution and a flat boundary surface, thus maintaining both visibility and boundary quality in bright spaces
Solution Approach 2:
The guide member creates a localized controlled environment for aerosol flow, ensuring that the aerosol is uniformly distributed only in the specific flow path region where light beam perception is needed, while maintaining a flat boundary with surrounding areas

Function Achieved in This Case
The system allows for clear perception of the light beam even in bright spaces, maintaining visibility from any direction and over longer distances by scattering the light within the aerosol flow path.

AI summary
A light beam emission system includes a blower that forms a flow path in which aerosol flows, an emitter that emits a laser beam, and a light guide that guides the laser beam to the flow path in which the aerosol flows. The light guide is hollow, and at least a part of the laser beam passing through the light guide and guided to the flow path propagates along the flow path of the aerosol.
