Rear View Camera Screen Integrated in Side Door Console
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rear view devices in motor vehicles without wing mirrors often restrict the driver's field of vision when the screen is placed near the A-pillar and can interfere with ventilation, and they require complex adjustments for installation and maintenance.
Innovation Solution
A rear view device with a camera and screen integrated into a side door console that engages with the dashboard recess, allowing for an ergonomic and unobstructed view, while also incorporating a ventilation duct for cooling and potential additional components like a tweeter, reducing visual occultation and maintaining ventilation functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the screen is arranged on the A-pillar, then the driver can see the rear view, but the field of vision is restricted by the windscreen
Solution Approach 1:
The screen is extracted from the A-pillar location and relocated to the side door console, removing the source of visual obstruction while preserving the rear view display function
Solution Approach 2:
The screen position is moved from the vertical A-pillar region to the horizontal side door console region, changing the spatial dimension of placement to achieve both visibility and unobstructed field of view
2Ease of manufacture
If the screen is arranged in the dashboard, then installation space is available, but the driver must move relative to the previous viewing angle
Solution Approach 1:
The side door console is positioned at the same ergonomic height and viewing level as the traditional wing mirror, creating an equipotential viewing position that requires no adjustment in driver posture or viewing angle
3Object-affected harmful factors
If the screen is arranged on the side door console, then the field of vision is unobstructed, but ventilation may be interfered with
Solution Approach 1:
The side door console is designed with segmented functional zones: an upper region for the screen that maintains unobstructed vision, and a lower region with integrated ventilation ducts that preserve airflow pathways
Solution Approach 2:
The side door console serves multiple functions simultaneously: it houses the screen for rear view display, maintains structural integrity for door assembly, and incorporates ventilation ducts for cabin airflow, eliminating single-function conflicts
4Adaptability or versatility
If a long video cable is used from camera to screen, then installation flexibility is improved, but EMC interference increases
Solution Approach 1:
The video cable routing is extracted from the traditional long-path installation through the vehicle body and reconfigured to follow the short direct path along the side door console, removing unnecessary cable length and interference sources
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
The solution provides an unobstructed driver view, minimizes visual interference, ensures undisturbed image reception, and allows for the use of high-resolution temperature-sensitive screens, while simplifying assembly and maintenance by keeping the video cable short and reducing the need for complex adjustments.
Implementation Method 1
The console has a ventilation duct which is communicatively connected to a ventilation rosette of the dashboard when the side door is closed, and is formed, in particular, for the ventilation of a side window and/or for the cooling of the screen
Implementation Method 2
at least one camera, by means of which at least one part of a rear space/traffic situation can be recorded
Data Source
AI summary
A motor vehicle having a rear view device with no wing mirrors is disclosed. The rear view device includes at least one camera, by which at least one part of a rear space/traffic situation can be recorded, and at least one screen, on which the image section recorded by the at least one camera can be displayed. The at least one screen is arranged on a console of a side door protruding towards the vehicle interior, where this console engages at least partially with a recess of the dashboard when the side door is closed.
