Imaging Heater Layout With Overlap Tolerance for Clear Windshield Views
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing heating devices for imaging systems on vehicle windshields require high accuracy in positioning, making their attachment difficult due to misalignment, which can decrease image clarity.
Innovation Solution
A heating device with an opening portion ahead of the camera unit and a heating section on the opposite side, where the heating section overlaps the opening portion and has a wider width, allowing for deviation in positioning without affecting the heated area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If high accuracy positioning is required for the heating member relative to the bottom wall, then the heated portion alignment with the light shielding hood is improved, but the attachment difficulty increases
Solution Approach 1:
The invention changes the dimensional parameters of the heating member, specifically making its width greater than the width of the opening portion in the light shielding hood. This parameter change allows the heating member to cover the entire opening portion even with positioning deviations, thereby maintaining heating effectiveness while reducing positioning accuracy requirements and simplifying attachment operations.
2Manufacturing precision
If the heating member is misaligned relative to the bottom portion of the light shielding hood, then the positioning accuracy is reduced, but the image clarity decreases
Solution Approach 1:
The invention increases the width parameter of the heating member beyond the opening portion width, creating a dimensional buffer that tolerates positioning misalignments. This ensures the heating member always covers the entire opening portion regardless of alignment variations, maintaining consistent heating quality and image clarity without requiring high positioning precision.
3Adaptability or versatility
If the width of the heating section is increased to be greater than the opening portion, then the positioning tolerance is improved, but the device complexity increases
Solution Approach 1:
The invention employs a simple parameter change approach by increasing the width of the heating member. This single dimensional modification provides positioning tolerance benefits without introducing complex structural elements, mechanisms, or additional components, thereby achieving adaptability improvement with minimal increase in device complexity.

Function Achieved in This Case
This design simplifies the attachment of the heating device by permitting deviation in positioning while ensuring the entire area is heated, thereby maintaining image clarity and reducing installation complexity.
Implementation Method 1
The heating member makes water drops, frost and ice attached to a portion of the window glass due to condensation disappear by heating the portion of the window shield glass corresponding to the light shielding hood

AI summary
A heating device for an imaging device is configured to heat a part of an attachment subject of the imaging device, and includes an opening portion located ahead of a light receiving portion that a camera unit has and opened along a direction away from the light receiving portion, and a heating section located on a side opposite to the attachment subject relative to the opening portion and having a sheet form. The heating section, in a view opposite to the opening portion relative to the attachment subject, at least overlaps a part of the opening portion, and in a portion of the opening portion where the heating section overlaps, in a width direction where the opening portion opens, a width of the heating section is greater than a width of the opening portion.
