Lens Group Housing With Side Thread Mounting for Compact ADAS Cameras
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera mounting methods for ADAS systems require multiple threaded connections that occupy significant space, hindering the compact design necessary for modern vehicle integration.
Innovation Solution
A camera mounting module with a lens group housing featuring a thread structure on its surface, allowing connection to an external housing system via a nut structure, and limiting structures to ensure precise positioning without obstructing the field of view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple threaded connection points are used on the back of the housing system, then the lens assembly can be securely mounted, but the camera assembly occupies a relatively large space
Solution Approach 1:
The patent moves the threaded connection points from the back surface to the lateral surface of the housing. This spatial reconfiguration allows the connection points to be positioned in a different dimension (from axial to radial direction), enabling secure mounting while reducing the axial space occupied by the camera assembly.
Solution Approach 2:
Instead of placing threaded connection points on the back of the housing as in conventional designs, the patent inverts the approach by positioning them on the lateral surface. This inversion allows the lens assembly to protrude forward while the connection points are distributed on the side, reducing the overall footprint.
2Strength
If threaded connections are positioned on the back of the housing, then secure mounting is achieved, but the field of view area is not optimized
Solution Approach 1:
The connection points are relocated from the back surface (axial dimension) to the lateral surface (radial dimension). This dimensional shift ensures that the threaded connections do not interfere with the forward-facing field of view, as they are now positioned on the side of the housing rather than occupying the central optical path area.
3Strength
If multiple threaded connection points are used, then secure mounting is achieved, but the production efficiency is reduced due to complex assembly
Solution Approach 1:
The lateral surface of the housing serves multiple functions: it provides structural support, accommodates the threaded connection points, and maintains the compact form factor. This multi-functional design consolidates several requirements into a single structural solution, simplifying the assembly process and improving production efficiency.
