Movable Visor for Head Restraint Display Glare Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle seating assemblies lack effective solutions to minimize glare from ambient light on in-vehicle displays, and existing designs do not adequately protect these displays from environmental elements.
Innovation Solution
A vehicle seating assembly with a movable visor that extends over the top portion of a display within the head restraint, allowing it to move between stowed and deployed positions, thereby reducing glare and protecting the display from environmental factors like rain and debris.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a display is incorporated into the head restraint, then viewing capability is improved, but glare from ambient light and exposure to environmental elements worsen
Solution Approach 1:
A visor assembly is introduced as an intermediary component between the ambient light/environment and the display. The visor includes a visor portion that positions over the display to block harmful light and environmental factors, while maintaining viewing capability through its transparent or translucent properties.
Solution Approach 2:
The visor assembly is made movable rather than fixed, allowing it to transition between a stowed position (where it does not interfere with the display) and a deployed position (where it provides protection). The movable configuration includes connection to the head restraint that enables this dynamic positioning.
2Object-affected harmful factors
If a fixed protective cover is added over the display, then protection from environmental elements is improved, but viewing quality and accessibility worsen
Solution Approach 1:
The protective visor is designed with movable capability, allowing it to be positioned in different states. When deployed, it provides protection; when stowed, it maintains full viewing quality and accessibility. This dynamic characteristic resolves the contradiction between protection and ease of operation.
Solution Approach 2:
The protective function is segmented from the display itself, allowing the visor to be independently controlled and positioned. This segmentation enables the protection mechanism to operate separately from the display functionality, maintaining viewing quality when protection is not needed.
