Vehicle Camera Lens Tilt Mechanism for Post-Install View Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing camera systems for lane keeping assist systems in vehicles require separate couplers for each vehicle due to differences in size and windshield angle, leading to increased manufacturing costs and challenges in adjusting the camera's angle of view effectively.
Innovation Solution
A camera device with a moving portion, a fixed portion, and an adjuster that includes an elastic member and a body, allowing for the adjustment of the optical axis by tilting the lens through a mechanism involving a base, side walls, and an adjusting member, enabling the angle of view to be adjusted within a desired range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate coupler is used for each vehicle to optimize the angle of view, then the angle of view can be optimized for each vehicle, but the manufacturing cost increases due to multiple molds
Solution Approach 1:
The patent implements an adjustable angle mechanism that allows the camera module to dynamically change its viewing angle after installation. The rotating member enables the imaging section to rotate around the optical axis, providing adaptability to different vehicle types without requiring separate fixed couplers for each vehicle model.
Solution Approach 2:
The patent creates a universal mounting structure that can be used across different vehicle types. Instead of designing specific couplers for each vehicle, a single mounting structure with adjustable angle capability serves multiple vehicle applications, reducing the number of molds needed while maintaining optimization capability.
2Ease of operation
If the camera module is fixed during installation, then the installation process is simplified, but the angle of view cannot be adjusted after mounting
Solution Approach 1:
The patent incorporates a rotating member that enables post-installation angle adjustment. The imaging section can be rotated to different angles after the camera module is mounted on the vehicle, allowing optimization of the viewing angle even after initial installation is complete.
Solution Approach 2:
The mounting structure is designed with preliminary adjustment capabilities built in, allowing the angle to be set during installation or adjusted afterward. The elastic member and rotating mechanism are pre-configured to enable easy angle changes without requiring complex disassembly or reinstallation procedures.
3Adaptability or versatility
If a complex adjustable mechanism is used to change the angle of view, then the angle can be optimized, but the device complexity increases
Solution Approach 1:
The patent uses a relatively simple rotating mechanism consisting of a rotating member and an elastic member. This dynamic structure allows angle adjustment without requiring complex multi-component mechanisms, maintaining simplicity while providing the necessary adaptability for different vehicle types and installation scenarios.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution allows for the camera device to adjust the angle of view within a desired range, minimizing changes due to manufacturing tolerances, mounting tolerances, and external forces, and enabling re-adjustment post-installation, thereby reducing costs and improving installation accuracy.
Implementation Method 1
the elastic member is formed integrally with the plate and may include a first region being extended to one side of the plate and a second region being bent from the first region. When the gap between the base of the body and the fixed portion becomes smaller, the gap between the first region and the second region of the elastic member may become smaller.

AI summary
A camera device comprises: a moving portion including a lens; a fixed portion coupled to the moving portion; a plate arranged between the moving portion and the fixed portion; and an adjuster which adjusts the movement of the moving portion. The adjuster comprises an elastic member, an adjusting member, and a body. The body comprises a base, a first sidewall extending from the base and coming into contact with the fixed portion, and a second sidewall extending from the base and coming into contact with the moving portion.
