Vehicle Imaging Device Rear Substrate Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of an electronic mirror in place of a rearview mirror in vehicles poses challenges in maintaining driver visibility of the area ahead, as existing imaging device configurations either burden the driver's eyes or obstruct the view when trying to position the electronic mirror further from the driver's seat, and bulky casings due to processing substrates hinder optimal placement.
Innovation Solution
The imaging device is configured with the processing substrate arranged at the rear of the camera module, allowing for a more compact design that reduces vertical distance between the imaging device and electronic mirror, enabling both clear visibility of the electronic mirror and the area ahead without obstructing the driver's view, with the substrate integrated within the casing and connected via flexible wiring for adaptability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electronic mirror is positioned closer to the driver's seat, then the driver can view the electronic mirror image more easily, but the driver's eyes are burdened due to the large distance difference between the electronic mirror and the area ahead
Solution Approach 1:
The patent positions the electronic mirror in the lower part of the imaging device casing, utilizing the vertical dimension rather than horizontal positioning. This allows the electronic mirror to be located away from the driver's seat horizontally while still being viewable, reducing the distance difference burden on the driver's eyes.
2Object-affected harmful factors
If the electronic mirror and imaging device are positioned further from the driver's seat, then the burden on the driver's eyes is reduced, but the driver cannot view the area ahead of the vehicle through the windshield
Solution Approach 1:
The patent utilizes vertical positioning within the imaging device casing to accommodate the electronic mirror, allowing the entire assembly to be positioned at an optimal distance from the driver's seat without compromising either electronic mirror visibility or windshield view.
Solution Approach 2:
The patent segments the imaging device structure by placing the electronic mirror in the lower part of the casing, separated from the main imaging components. This allows independent positioning and optimization of each component's function.
3Object-affected harmful factors
If the processing substrate is arranged in the lower part of the imaging device, then the imaging device can be positioned away from the driver's seat, but the casings become bulky
Solution Approach 1:
The patent integrates the processing substrate within the imaging device casing structure, nesting it in a space-efficient arrangement. The substrate is positioned to utilize available space within the casing, reducing overall volume while maintaining functional separation.

AI summary
In an imaging device mounted in the interior of a vehicle, a camera module is arranged so as to image the area ahead of the vehicle via a windshield. A processing substrate is provided integrally with the camera module and includes a processing part that controls the camera module. When the side on which an incident light receiving face exists in the camera module is defined as camera front and the side opposite to the camera front is defined as camera rear, the whole processing substrate is arranged at the camera rear with respect to the camera module.
