Intersecting Dual-Surface Reflector for Wide-Angle Light Direction Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing position detection apparatuses face difficulties in easily adjusting the radiation direction of light, leading to limitations in detecting the position of reflected light across a wider region.
Innovation Solution
A reflector with a first reflection surface and a second reflection surface that intersects with the first, allowing for easy adjustment of the radiation direction by reflecting light from both surfaces, and an adjustment method that detects the position of reflected light to adjust the radiation direction accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single reflection surface is used, then the device complexity is reduced, but the radiation direction adjustment capability and detection range are limited
Solution Approach 1:
The reflector is divided into multiple independent reflection surfaces (first reflection surface and second reflection surface) that can be adjusted separately. Each surface can be independently positioned to reflect light in different directions, enabling versatile radiation direction adjustment while maintaining manageable structural complexity through modular design
2Area of stationary object
If multiple reflection surfaces are added to expand detection range, then the detection range increases, but the device complexity increases
Solution Approach 1:
The reflector structure extends into multiple spatial dimensions by adding reflection surfaces at different orientations and positions. The first reflection surface and second reflection surface are arranged to reflect light toward different regions, effectively expanding the detection range in three-dimensional space without requiring an overly complex multi-component system
3Area of stationary object
If the second reflection surface is made inclined, then the detection region is widened, but the manufacturing precision requirements increase
Solution Approach 1:
The inclination angle of the second reflection surface is optimized to balance detection region expansion with manufacturing feasibility. By carefully selecting the inclination parameter, the design achieves wider detection coverage while maintaining reasonable manufacturing precision requirements that can be met with standard fabrication tolerances
