Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles face difficulties in detecting targets with high absorption or low reflectance of near-infrared and infrared wavelengths due to lack of returned light from LIDAR systems.
Innovation Solution
A vehicle body panel structure comprising a substrate with a detectable layer configured to interact with electromagnetic spectra, a decorative layer that reflects and transmits specific bands, and a top layer that transmits both visible and non-visible bands, enhancing reflectivity and visibility to LIDAR systems while allowing decorative freedom.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a vehicle body panel uses conventional paint or coating materials, then decorative freedom and aesthetic appearance are maintained, but LIDAR detection accuracy deteriorates due to high absorption or low reflectance of infrared wavelengths
Solution Approach 1:
The coating system is segmented into multiple functional layers: a detectable layer containing infrared-reflective particles for LIDAR detection, a decorative layer providing aesthetic appearance with pigments, and a top protective layer. Each layer performs a specific function, allowing the coating to simultaneously achieve LIDAR detectability and decorative freedom without compromising either aspect.
2Measurement precision
If a detectable layer is added to enhance LIDAR visibility, then detection accuracy improves, but device complexity and manufacturing steps increase
Solution Approach 1:
The detectable layer, decorative layer, and top layer are combined into a single integrated coating system that can be applied in sequence. The detectable layer is merged with the base coat, while the decorative and protective functions are integrated into subsequent layers, creating a unified solution that enhances LIDAR detection without requiring separate complex systems.
Solution Approach 2:
The multi-layer coating system serves multiple functions simultaneously: the detectable layer provides LIDAR reflectivity, the decorative layer provides aesthetic appearance, and the top layer provides protection. This universal coating system replaces the need for separate detection devices or modifications, achieving multi-functionality in a single integrated solution.
3Measurement precision
If infrared-reflective particles are incorporated into the coating, then LIDAR detection improves, but manufacturing precision requirements increase due to particle distribution control
Solution Approach 1:
The coating formulation parameters are optimized to ensure proper dispersion of infrared-reflective particles. By controlling particle concentration, size distribution, and chemical composition of the binder, the system achieves uniform particle distribution without requiring excessive manufacturing precision. The particles are incorporated at specific concentrations (e.g., 1-10 wt%) to balance detection performance with manufacturability.
