Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image recognition devices can only emit light in a single direction, which limits their ability to recognize multiple pieces of image information on holograms at different angles or directions.
Innovation Solution
The device features multiple light sources circumferentially mounted on a circuit board, providing multiple light emitting directions, and an imaging component with a circular or columnar linear array lens to uniformly image light from these sources, allowing for recognition of images at various angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple light sources are added to provide multi-directional light emission, then the ability to recognize hologram information at different angles is improved, but the device complexity increases
Solution Approach 1:
The patent divides the lighting system into multiple independent light sources (at least three) arranged circumferentially around the optical axis. Each light source can be independently controlled to emit light in different directions, enabling the system to capture hologram information from multiple angles. This segmentation allows the device to overcome the limitation of single-direction light emission while maintaining manageable complexity through modular design.
Solution Approach 2:
The patent transitions from a single light source emitting in one direction to multiple light sources arranged in a circumferential pattern around the optical axis. This spatial arrangement adds a dimensional aspect to the lighting system, creating a three-dimensional lighting configuration that enables multi-directional illumination and captures image information from different angular perspectives.
