A-Pillar Camera Packaging for Clear Imaging and Pillar Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle camera mounting solutions, such as those on windshields or traditional A-pillars, suffer from image quality issues due to optical distortions, reflections, and structural instability, while integrating cameras into A-pillars without compromising stability remains a challenge.
Innovation Solution
A camera is designed to occupy a smaller space within the A-pillar, with dimensions aligned to minimize interference with the pillar's structure, allowing for stable integration and high-quality image capture without windshield interference, using a compact 'satellite camera' configuration with external processing units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the camera is mounted in the A-pillar, then the image quality is improved by avoiding windshield interference, but the A-pillar structure becomes less stable due to removal of support structure
Solution Approach 1:
The patent reorients the camera's optical axis to be substantially perpendicular to the A-pillar's longitudinal direction, changing the spatial dimension of image capture from the traditional forward-facing orientation to a side-oriented perspective. This dimensional change allows the camera to be positioned within the A-pillar without requiring extensive structural modifications, thereby maintaining pillar stability while achieving clear imaging without windshield interference
2Ease of manufacture
If the A-pillar is made wider to accommodate the camera, then the camera integration is improved, but the driver's field of vision is reduced due to increased blind spot area
Solution Approach 1:
The patent integrates the camera within the existing A-pillar structure by positioning it in a recessed manner, where the camera housing is substantially contained within the A-pillar's cross-sectional boundaries. This nesting approach allows complete camera integration without increasing the A-pillar's external dimensions, thereby maintaining the driver's field of vision while achieving stable camera mounting
3Device complexity
If the camera is mounted behind the windshield, then the front camera configuration is simplified, but the image quality deteriorates due to optical distortions and reflections
Solution Approach 1:
The patent extracts the camera from the traditional windshield-mounted position and relocates it to the A-pillar structure. This extraction removes the camera from the optical path of the windshield, eliminating the harmful effects of windshield glass including optical distortions, reflections, and soiling. The camera is repositioned to capture images from a location that does not require viewing through the windshield, thereby significantly improving image quality

AI summary
(Camera, A-pillar arrangement having the camera and vehicle) Camera (3, 103, 203) for a vehicle (1), which camera is designed: to be mounted at least partially inside an A-pillar (7, 107, 207) of the vehicle (1), to record image data for an area in front of the vehicle (1), and to be arranged in the A-pillar (7, 107, 207) in such a way that a space (24, 124, 224) taken up by the camera (3, 103, 203) inside the A-pillar (7, 107, 207) has a smaller maximum dimension (A1, A3, A5) parallel to a line of sight (14, 114, 228) of the camera (3, 103, 203) than its maximum dimension (A2, A4, A6) parallel to a longitudinal direction (L) of the A-pillar (7, 107, 207).
