Driver Monitoring Camera Mount With Spherical Optical Axis Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver monitoring systems in vehicles require different housing and cover parts for various car lines due to varying ECU positions, leading to high development, validation, and manufacturing costs, and lack of shared components across car lines.
Innovation Solution
A driver monitoring system with a camera sub-assembly housed in an outer housing, featuring a spherical outer topology and a retainer ring with a spheroidal inner topology for angular adjustment of the optical axis, allowing for secure orientation and reduced part diversity across different car lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If diverse housing and cover parts are used for different car lines, then the driver monitoring system can accommodate various installation positions, but the development, validation, and manufacturing costs increase
Solution Approach 1:
The housing is designed with a universal spherical mounting structure that can accommodate multiple installation positions and orientations through angular adjustment, eliminating the need for diverse housing variants for different car lines while maintaining adaptability
2Ease of manufacture
If the optical axis position is fixed during manufacturing, then the assembly process is simplified, but the system cannot be adjusted for different car lines
Solution Approach 1:
The mounting structure incorporates dynamic angular adjustment capability, allowing the optical axis orientation to be modified after assembly according to different car line requirements, combining manufacturing simplicity with operational flexibility
3Reliability
If multiple fixation elements are used to maintain optical axis orientation, then the positioning stability is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The spherical mounting structure enables self-alignment and self-positioning of the camera sub-assembly, maintaining optical axis orientation through the geometric constraints of the spherical interface without requiring additional fixation elements
