Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems face challenges in accurately displaying road surface information using headlamps due to variations in headlamp mounting locations and sizes, leading to distorted information on the road surface, which can increase hardware costs.
Innovation Solution
A vehicle system device comprising a headlamp, storage for mounting information, and a controller with a road surface information generator, coordinate converter, and headlamp controller to convert location coordinates into angle coordinates, allowing precise emission of road surface information based on the headlamp's position and distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the hardware configuration of the headlamp is improved to correct distorted road surface information, then the accuracy of road surface information display is improved, but the manufacturing cost increases
Solution Approach 1:
The patent changes the parameter representation from location coordinates to angle coordinates, which inherently accounts for the headlamp's mounting position and distance. This parameter transformation allows the system to display accurate road surface information without requiring hardware modifications, thereby maintaining manufacturing precision while avoiding increased manufacturing costs
Solution Approach 2:
The patent creates a virtual coordinate transformation model that copies and adapts the road surface information display to different headlamp configurations. Instead of modifying the physical headlamp hardware, the system uses software-based coordinate conversion to achieve accurate information display across various mounting positions and distances
2Adaptability or versatility
If the headlamp mounting location or vehicle size varies, then the adaptability of the system is improved, but the road surface information becomes distorted
Solution Approach 1:
The patent transforms the coordinate system from fixed location-based coordinates to angle-based coordinates that are relative to the headlamp's position. This parameter change enables the system to adapt to different mounting locations and vehicle sizes while maintaining accurate road surface information display, as the angle coordinates automatically adjust to the headlamp's specific configuration
Solution Approach 2:
The coordinate conversion mechanism serves as a universal solution that works across different headlamp mounting positions, vehicle types, and road surface conditions. By using angle coordinates as a common reference frame, the system achieves multi-functionality and adaptability without sacrificing display accuracy
