Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing DFC mounting systems lack adjustability, limiting the camera's field of view and failing to accommodate varying windshield angles, resulting in blind spots and suboptimal image capture.
Innovation Solution
A DFC assembly with a chassis, swing arm, and mount system that allows for lateral angle adjustment and rake compensation, enabling flexible camera positioning to accommodate different windshield geometries and improve image capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed mounting system is used for the DFC, then the device complexity is reduced, but the field of view and adaptability to different windshield angles are limited
Solution Approach 1:
The mounting system employs a dynamic adjustable structure with multiple degrees of freedom, allowing the camera to be positioned at various angles and orientations. The swing arm mechanism enables lateral angle adjustment while the rake compensation mechanism adapts to different windshield angles, transforming a static fixed mounting system into a dynamic adaptable one.
Solution Approach 2:
The mounting system is divided into separate functional modules: a swing arm assembly for lateral angle adjustment and a rake compensation mechanism for windshield angle adaptation. This segmentation allows each component to independently perform its specific adjustment function, achieving complex adaptability through coordinated simple mechanisms.
2Area of moving object
If a fixed mounting system is used for the DFC, then the device complexity is reduced, but the field of view is limited resulting in blind spots
Solution Approach 1:
The adjustable mounting system enables the camera to dynamically position itself to capture optimal fields of view. By allowing lateral angle adjustment through the swing arm mechanism, the camera can be oriented to eliminate blind spots and maximize the captured area of driver and cabin.
Solution Approach 2:
The mounting system adds angular dimensionality to the camera positioning, transitioning from a single fixed position to multiple adjustable orientations. This enables the camera to access different spatial perspectives and expand the effective field of view area by capturing images from optimized angles.
3Ease of manufacture
If the DFC mounting system lacks adjustability, then the ease of manufacture is improved, but the image capture quality deteriorates
Solution Approach 1:
The mounting system incorporates adjustable mechanisms that allow post-manufacturing optimization of camera positioning. Rather than requiring extremely precise fixed mounting during manufacturing, the system enables field adjustment to achieve optimal image capture quality, reducing manufacturing precision requirements while maintaining high imaging performance.

AI summary
In some implementations, a mounting assembly may include a chassis having a platform portion, and a spine portion. The mounting assembly may include an end lock having a shaft portion engaged with the spine portion, and a cap portion configured to engage with a lock projection of a camera module, wherein the camera module is to be disposed between the platform portion and the cap portion. The mounting assembly may include a mount configured to mount the mounting assembly. The mounting assembly may include a swing arm pivotably coupled to the chassis by a first hinge, and pivotably coupled to the mount by a second hinge, where a first axis of rotation of the first hinge is orthogonal to a second axis of rotation of the second hinge.
