Camera Optics Carrier Mounting for Axial Force Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of camera systems in vehicle environments is challenging due to forces acting on the optics, causing unwanted focus adjustments, and existing systems lack flexibility for different housing applications.
Innovation Solution
A camera system design featuring a basic housing part with a contact area for the optics carrier, which is permanently fixed to prevent axial forces on the optics, ensuring a defined position and long-term reliability, along with a mounting part that acts on the optics carrier to maintain alignment without axial forces, and a sealing ring for secure optics placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the camera system is installed close to the environment in the housing, then the detection capability is improved, but axial forces act on the optics causing unwanted focus adjustment
Solution Approach 1:
The patent introduces an intermediary mounting structure consisting of a mounting plate and mounting elements that mediate between the housing and the optics carrier. This intermediary structure transfers axial forces away from the optics, allowing the camera system to be installed close to the environment while preventing unwanted focus adjustment through proper force distribution.
Solution Approach 2:
The mounting structure is segmented into multiple components: a mounting plate, multiple mounting elements distributed across the plate, and a optics carrier with separate contact sections. This segmentation allows forces to be distributed across multiple contact points rather than concentrated on the optics, preventing focus adjustment while maintaining installation proximity.
2Reliability
If the optics carrier is firmly fixed to prevent position changes, then long-term reliability is improved, but the system becomes less flexible for different housing applications
Solution Approach 1:
The mounting plate serves multiple functions: it provides a stable base for permanent fixation to ensure reliability, while also accommodating different housing configurations through its flexible mounting element arrangement. The universal design allows the same mounting structure to be adapted to various housing types and application scenarios.
Solution Approach 2:
The mounting structure incorporates dynamic characteristics by allowing the optics carrier to be firmly fixed in the axial direction while maintaining flexibility in radial and rotational adjustments. This dynamic mounting approach enables reliable fixation without sacrificing adaptability to different housing applications.
3Stability of the object's composition
If the optics carrier is permanently fixed in the housing, then position stability is improved, but installation flexibility is reduced
Solution Approach 1:
The mounting structure is designed to allow preliminary positioning and alignment of the optics carrier before permanent fixation. The mounting elements enable initial placement and adjustment, after which the optics carrier can be permanently fixed to achieve both installation flexibility and position stability.
