Windshield Sensor Mount With Offset Heating for Clear Camera Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle camera devices with heating wires placed between the camera and windshield can interfere with image capturing, potentially sacrificing camera accuracy due to the wire's presence.
Innovation Solution
An attachment apparatus with a supporting section, a heating section, and a conducting section that dissipates heat from the heating section towards the windshield, ensuring the camera's lens is exposed and not obstructed, while effectively preventing windshield fogging without interfering with the camera's field of view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a heating wire is placed between the camera and the windshield to prevent fogging, then the windshield fogging is removed, but the heating wire interferes with image capturing and deteriorates detection accuracy
Solution Approach 1:
The heating wire is extracted from the optical path between the camera and windshield. Instead, a heating section is attached to the back surface of the windshield, separating the heating function from the imaging path, thus eliminating interference with image capture while maintaining fog prevention capability
Solution Approach 2:
A bent section with a window section is introduced as an intermediary structure. This bent section positions the heating element on the back surface while creating a window that exposes the sensor to the transparent plate, mediating between the heating requirement and the imaging requirement
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 prevents deterioration of detection accuracy by uniformly heating the windshield to remove fogging, ensuring clear image capture without obstructing the camera's view or affecting its performance.
Implementation Method 1
a heating section that is placed on a back surface on an opposite side of the facing surface of the bent section
Implementation Method 2
a conducting section that is placed so as to extend along the facing surface, and conducts, along the facing surface, heat conducted from the heating section
