Pull-Out Sun Visor Assembly With Integrated Display Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sun visors in vehicles have limitations in blocking sunlight due to size constraints and require manual adjustment, which can be hazardous while driving, and separate mounts for displays can damage the roof panel and obstruct the driver's view.
Innovation Solution
A convenience equipment pull-out device for vehicles that includes a housing mounted on the headliner with a movable body and pull-out portion, allowing a sun visor with a display panel to be electrically slid and rotated for enhanced functionality, providing vehicle information and entertainment while protecting the driver from sun glare.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the sun visor size is increased to improve sunlight blocking capability, then the shading effectiveness is improved, but the mounting area constraint is worsened
Solution Approach 1:
The sun visor is nested within the headliner assembly, allowing it to be stored compactly in the retracted position while providing full functionality when deployed. The pull-out structure enables the visor to extend beyond the typical mounting area constraints when needed.
Solution Approach 2:
The sun visor transitions from a static fixed-size component to a dynamic adjustable component that can extend and retract. The pull-out mechanism allows the visor length to be changed based on the required shading area, resolving the contradiction between size and mounting space.
2Object-affected harmful factors
If manual adjustment of the sun visor angle is implemented, then the shading coverage is improved, but the driving safety is worsened due to driver distraction
Solution Approach 1:
The sun visor system performs self-adjustment through automatic sensing mechanisms that detect sunlight intensity and visor position, eliminating the need for manual driver intervention. The system autonomously optimizes shading coverage while maintaining driving safety.
Solution Approach 2:
The system incorporates sensors that provide feedback on sunlight intensity and visor position, enabling automatic adjustment mechanisms to optimize shading coverage without requiring driver attention, thus resolving the safety contradiction.
3Adaptability or versatility
If a separate mount is installed on the roof panel for display mounting, then the display installation is improved, but the roof panel integrity is worsened due to potential damage
Solution Approach 1:
The display mounting function is merged with the headliner assembly structure, eliminating the need for separate roof panel mounts. The integrated design provides display installation capability while preserving roof panel integrity by avoiding additional mounting holes or attachments.
Solution Approach 2:
The headliner assembly is designed to serve multiple functions: sun visor housing, display mounting structure, and structural component. This multi-functionality eliminates the need for separate display mounts on the roof panel, maintaining structural integrity.
4Adaptability or versatility
If a separate mount is installed on the front window or roof panel for display mounting, then the display installation is improved, but the driver's view is worsened due to obstruction
Solution Approach 1:
The display is nested within the headliner assembly, positioning it in a location that does not obstruct the driver's forward view. The integrated design allows display installation while maintaining clear visibility through the windshield and side windows.
