Pivotable Sun Visor HUD for Driver Information Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sun visors in vehicles lack integrated display solutions that provide essential information to drivers and passengers in a convenient and non-distracting manner, especially when in use or stowed positions.
Innovation Solution
A sun visor assembly with a pivotable display mounted on the visor, capable of switching between stowed and viewing positions, which can display navigation information, time, speed limits, weather, and other data, and communicates with vehicle information systems or mobile devices via wireless connections, allowing for easy viewing without obstructing the driver's line of sight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a display is integrated into the sun visor, then information accessibility is improved, but device complexity increases
Solution Approach 1:
The patent combines the display device with the sun visor assembly, integrating navigation, communication, and entertainment functions into a single unified structure. The display is mounted within the visor body, and the visor pivot mechanism is integrated with the display positioning system, allowing both components to work together as one assembly rather than separate units.
Solution Approach 2:
The sun visor assembly is designed to perform multiple functions: traditional sun blocking, information display, navigation, communication, and entertainment. The display can show various types of information (navigation directions, calls, messages, media control), and the visor can be positioned in different orientations to accommodate different viewing needs and sun positions.
2Ease of operation
If the display is mounted on the visor, then information is provided in a convenient location, but the visor structure becomes more complex
Solution Approach 1:
The display is designed to be movable relative to the visor, capable of pivoting between a stowed position (flush with or recessed in the visor) and a viewing position (extended outward at an optimal viewing angle). The visor itself is also movable, pivoting between a stowed position against the windshield and a deployed position extending outward, allowing the display to maintain optimal positioning regardless of visor orientation.
Solution Approach 2:
The visor assembly is divided into distinct functional segments: the visor body, the display unit, the pivot mechanism, and the mounting structure. This segmentation allows each component to be optimized independently while maintaining overall integration, simplifying manufacturing and maintenance.
3Ease of operation
If the display pivots between stowed and viewing positions, then viewing comfort is improved, but mechanical complexity increases
Solution Approach 1:
The display is designed to be movable relative to the visor, capable of pivoting between a stowed position (flush with or recessed in the visor) and a viewing position (extended outward at an optimal viewing angle). This dynamic positioning allows users to adjust the display to their preferred viewing angle while minimizing its profile when not in use.
4Loss of information
If the display shows information while the visor is deployed, then information accessibility is maintained, but the display may obstruct the driver's view
Solution Approach 1:
The display positioning system allows the display to pivot independently of the visor deployment, enabling it to be positioned in a viewing orientation even when the visor is in its deployed sun-blocking position. The display can be angled to direct information toward the driver's peripheral vision or upper field of view, minimizing obstruction of the forward road view.
