Sun Visor Camera Display for Rear Passenger Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle sun visors lack the ability to display external views, such as traffic lights or rear passengers, and do not have features like photo/video capture or sharing, limiting visibility and capturing moments during travel.
Innovation Solution
A sun visor system with integrated cameras and a touchscreen display that provides real-time images from front and rear cameras, allowing users to view blocked external environments, capture images/videos, and share them wirelessly, while also acting as a regular mirror when needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a sun visor is deployed to block sunlight or glare, then visibility of external environment (traffic lights, road signs) is blocked, but the sun visor successfully blocks unwanted light
Solution Approach 1:
The patent uses cameras to capture images of the external environment and displays them on a screen mounted on the sun visor. This creates a visual copy of the blocked view, allowing passengers to see traffic lights and road signs without moving the visor, thus resolving the contradiction between blocking sunlight and maintaining visibility
Solution Approach 2:
The patent introduces a camera-screen system as an intermediary between the external environment and the passenger's view. The camera captures the external scene and the screen presents it to the passenger, mediating the information flow and allowing the visor to block physical light while preserving visual information access
2Loss of information
If existing sun visor mirrors are used to view interior, then interior visibility is improved, but external view and rear passenger visibility are not provided
Solution Approach 1:
The patent transforms the sun visor from a single-function mirror into a multi-functional device that can display multiple camera feeds including external views, interior views, and rear passenger views. The screen can switch between different camera inputs, making the visor adaptable to various viewing needs and resolving the limitation of single-purpose mirrors
Solution Approach 2:
The patent makes the visor display dynamic by allowing switching between different camera views (external, interior, rear passengers) based on user needs. The display can adaptively show different information at different times, transforming the static mirror into a dynamic information presentation system
3Ease of operation
If sun visor mirrors are used for viewing, then basic reflection is provided, but photo/video capture and sharing capability is lacking
Solution Approach 1:
The patent merges the viewing function with photo/video capture and sharing capabilities into a single integrated system. The same camera system that provides viewing capability also captures images and videos, which can then be shared wirelessly through the vehicle's communication system, combining multiple functions that were previously separate or non-existent

AI summary
An automotive audio visual system includes a display screen on the vehicle, such as the central display screen on the vehicle's dashboard, and one or more rear cameras facing a rear passenger seat of the vehicle. The image or video feed from one or more rear cameras is displayed on the display screen in the vehicle, so that the front passengers can view the rear passenger area on the vehicle's display screen.
