Adjustable Vehicle Camera Mount for Viewing Angle Tolerance Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing camera systems for vehicles, particularly those used in Lane Keeping Assist Systems, require separate configurations for each vehicle due to size and windshield angle differences, leading to increased costs and variability in viewing angle optimization.
Innovation Solution
A camera device with a rotatable camera module, a viewing angle adjustment member, and a support member that includes a hook portion and screw thread, allowing for adjustable viewing angles to compensate for manufacturing and mounting tolerances, as well as external forces, to achieve a desired direction angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If separate configurations are used for each vehicle to optimize viewing angle, then viewing angle optimization is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The camera module is designed with rotatable capability, allowing the viewing angle to be dynamically adjusted after installation. The rotation mechanism enables the camera to adapt to different vehicle types and windshield angles without requiring separate fixed configurations for each vehicle model.
Solution Approach 2:
The viewing angle is changed by rotating the camera module around a first axis, transforming the fixed parameter approach into an adjustable parameter system. This allows the same camera device to achieve optimal viewing angles across different vehicle configurations by changing the rotation angle parameter.
2Manufacturing precision
If separate configurations are used for each vehicle, then viewing angle optimization is improved, but manufacturing cost increases
Solution Approach 1:
The camera device is designed as a universal solution that can be installed on various vehicle types. The rotatable camera module and adjustable viewing angle mechanism enable a single standardized design to serve multiple vehicle models, eliminating the need for vehicle-specific configurations and reducing manufacturing costs.
Solution Approach 2:
By making the viewing angle adjustable through rotation rather than fixed during manufacturing, the system reduces manufacturing complexity and cost while maintaining the ability to achieve optimal viewing angles for different vehicle types through post-installation adjustment.
3Device complexity
If fixed camera configuration is used, then device complexity is reduced, but viewing angle optimization deteriorates
Solution Approach 1:
The camera module incorporates a rotation mechanism that allows it to change its viewing angle dynamically. This dynamic capability enables the system to maintain configuration simplicity while achieving viewing angle optimization by adjusting the rotation angle after installation rather than requiring complex pre-configured solutions.
4Manufacturing precision
If adjustable viewing angle mechanism is added, then viewing angle optimization is improved, but device complexity increases
Solution Approach 1:
A rotation mechanism is introduced that allows the camera module to rotate around a first axis. This relatively simple dynamic mechanism enables viewing angle adjustment without requiring complex multi-component systems, achieving a balance between adjustability and mechanism simplicity.
