Smart Vehicle Sun Visor with Touch Screen and Camera Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle sun visors lack the ability to display external views when deployed, do not provide rear passenger visibility, and cannot capture or upload photos/videos, limiting drivers' and passengers' ability to see external information and capture travel memories.
Innovation Solution
A sun visor system integrated with a touch screen display, cameras, and a computer processor that allows real-time image display, glare reduction, and wireless image/video sharing, featuring a polarized front camera, a 'see-me' camera for user view, and rear cameras for passenger visibility, with video chat functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a sun visor is deployed to block glare, then glare reduction is improved, but external visibility is worsened
Solution Approach 1:
A camera is positioned to capture external views that would otherwise be blocked by the deployed sun visor. The camera acts as an intermediary, recording the external environment and transmitting this information to a display device, allowing users to see outside the vehicle without moving the visor away from its glare-blocking position.
Solution Approach 2:
The system transitions from direct optical viewing (line-of-sight) to electronic image transmission. By capturing images through a camera and displaying them on a screen, the system creates a new dimensional pathway for information delivery, bypassing the physical obstruction caused by the sun visor.
2Ease of operation
If a traditional mirror is used on the sun visor, then self-viewing is improved, but external view and passenger visibility are worsened
Solution Approach 1:
The display device serves multiple functions: it can show the user's own image (replacing the mirror function), display external views captured by the camera, and show images of rear passengers. This multi-functional approach eliminates the need for separate devices for each purpose.
Solution Approach 2:
The system dynamically switches between different camera feeds and display modes based on user selection. Users can toggle between viewing themselves, viewing external scenes, or monitoring rear passengers, making the single display device adaptable to different needs.
3Device complexity
If no additional devices are added to the sun visor, then device complexity is improved, but functionality is worsened
Solution Approach 1:
The camera, display device, and control interfaces are integrated into the sun visor assembly, combining multiple functions (glare blocking, imaging, display, and interaction) into a single unified structure. This merging approach adds functionality while maintaining relative structural simplicity.
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
Enables drivers and passengers to view blocked external environments, capture and share images/videos, and engage in real-time video chats, enhancing visibility and travel documentation while minimizing distractions during driving.
Implementation Method 1
A front facing polarized camera shows the area of view which is normally blocked by the sun visor when it is deployed
Data Source
AI summary
A vehicle sun visor system with a touch screen display is configured to display video feed from one or more cameras. A front facing polarized and/or photochromic camera shows the area of view which is normally blocked by the deployed sun visor, allowing the user to view traffic lights, road signs, etc. without the distraction of glare. Software image processing may also be used to reduce glare and improve visibility. In addition, the sun visor system also has a “see-me” camera which allows the user to use the screen as a mirror, and one or more rear-view cameras which can be used to see the passenger area of a vehicle through the touch-screen display. Any of the cameras may be used to take photos or videos, which may be viewed on the display and transmitted wirelessly to other electronic devices or cloud storage.
