Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional object localization devices using light modules aligned on the same axis face alignment errors, complexity, and high production costs due to the use of complex light guides, making them difficult to implement and adjust.
Innovation Solution
A device with at least two illumination modules emitting combined secondary light distributions, masked by an optical component, allows for spatially varying main light distributions, using standard components that are easier to arrange and adjust, enabling precise object localization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If complex light guides are used to obtain spatially variable intensities, then the light distribution control is improved, but the device complexity and production cost increase
Solution Approach 1:
The patent replaces expensive, complex light guides with inexpensive optical diffusers that can be easily manufactured and replaced. The diffusers are simple optical elements that provide the necessary spatial intensity variation without requiring complex shapes or precise alignments, effectively using cheap optical components to solve the problem of achieving spatially variable light distribution.
Solution Approach 2:
The patent changes the optical parameters by using multiple optical diffusers with different properties (different diffusion angles, transmission characteristics) to achieve spatially variable intensity distribution. Instead of changing the physical shape of light guides, the solution modifies the optical parameters through selection and combination of diffusers with specific characteristics, thereby controlling light distribution in a simpler manner.
