Integrated Camera Device for Vehicle Windshield and Exterior Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
It is challenging to install windshield information detection cameras and vehicle exterior information detection cameras in a vehicle with a structured fixation that allows for efficient integration and accurate operation.
Innovation Solution
A camera device that combines a windshield information detection camera and a vehicle exterior information detection camera, where both cameras are fixed to each other and housed in a single case, which is then attached to the vehicle, allowing them to capture overlapping images and share a common circuit substrate for image processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If windshield information detection camera and vehicle exterior information detection camera are separately fixed to the vehicle, then each camera can be independently installed and maintained, but the installation process becomes complex and time-consuming
Solution Approach 1:
The patent combines the windshield information detection camera and vehicle exterior information detection camera into a single integrated camera device with a unified housing structure. This merging allows both cameras to be installed as one unit rather than separately, simplifying the installation process while maintaining independent functionality of each camera system.
2Shape
If multiple cameras are installed separately in the vehicle, then each camera can be independently positioned, but the number of parts increases and aesthetic appeal decreases
Solution Approach 1:
The patent integrates multiple camera units into a single housing structure, reducing the number of separate parts while maintaining the functional independence of each camera. This unified structure improves aesthetic appeal by presenting a clean, integrated appearance rather than multiple separate camera components mounted on the vehicle.
Solution Approach 2:
The single camera housing serves multiple functions by accommodating both the windshield information detection camera and the vehicle exterior information detection camera. This multi-functional design eliminates the need for separate housings and mounting structures for each camera, reducing part quantity while maintaining independent positioning capabilities.
3Measurement precision
If cameras are fixed separately to the vehicle, then each camera can be independently adjusted, but positioning precision and stability decrease
Solution Approach 1:
The patent combines multiple camera units into a single integrated device with a unified mounting structure. This integration provides a stable common reference frame for all cameras, improving positioning accuracy and reducing relative movement between cameras while maintaining the ability to precisely position the entire assembly on the vehicle.
