Overhead Console Rearview Camera Display System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large screen DVD players in vehicles obstruct the driver's rearview mirror, creating safety hazards and blind spots, as they block the driver's line-of-sight and restrict the view at certain angles, necessitating a solution to ensure clear rearview visibility while maintaining passenger entertainment.
Innovation Solution
A video display system with a rearview camera providing an image feed to a first video screen, which projects the image onto the rearview mirror, synchronized with the mirror's position, and an image processing system to enhance the image, ensuring the driver's clear view even with larger screens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a large screen DVD player is installed in the overhead console, then passenger entertainment quality is improved, but the driver's rearview visibility is obstructed
Solution Approach 1:
The overhead console is divided into separate functional zones: an upper entertainment section for the DVD player and a lower rearview section for the mirror and camera. This segmentation allows both functions to coexist without interference, with the entertainment screen positioned above the driver's line of sight and the rearview system positioned below it.
Solution Approach 2:
The rearview system transitions from a traditional optical mirror to an electronic display system with a camera mounted on the overhead console and a display screen positioned in the lower console area. This dimensional repositioning moves the rearview function to a location that does not block the driver's forward view while maintaining visibility of rear objects.
2Volume of stationary object
If the DVD player screen is positioned in the line-of-sight of the rearview mirror, then space utilization is improved, but driving safety is compromised
Solution Approach 1:
The console space is segmented into distinct functional layers: the upper layer houses the entertainment DVD player utilizing overhead space, while the lower layer contains the rearview camera and display. This vertical segmentation maximizes space utilization while maintaining clear separation between entertainment and safety functions.
Solution Approach 2:
A camera acts as an intermediary device mounted on the overhead console to capture rearview images, which are then displayed on a separate screen in the lower console. This intermediary system allows the DVD player to occupy overhead space without directly blocking the driver's view, as the rearview function is mediated through electronic imaging rather than direct optical reflection.
3Object-affected harmful factors
If the video screen is folded upward to clear the rearview mirror, then rearview visibility is improved, but passenger viewing capability is lost
Solution Approach 1:
The entertainment and rearview functions are segmented into permanently positioned separate units: the DVD player in the upper overhead console and the rearview display in the lower console. This eliminates the need for folding or moving parts, as both functions operate simultaneously in fixed positions without interfering with each other.
Solution Approach 2:
Instead of folding the entertainment screen upward to clear the rearview path (as in traditional designs), this invention inverts the approach by positioning the rearview display downward in the lower console while keeping the entertainment screen upward in the overhead console. This inversion resolves the conflict by making both screens permanently visible to their respective users without requiring mechanical movement.

AI summary
A video display system for a vehicle includes a first video display for providing an image projection to a rearview mirror of the vehicle, and a second video display mounted behind the first video display. A camera can provide an image feed to the first video display, and the second video display can display media content such as DVD media.
