Slide-Type Sun Visor Structure for Panoramic Windshield Shading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sun visors struggle to effectively block sunlight from panoramic windshields without interfering with the driver's head, causing appearance and marketability issues due to exposed rail portions and limited shading capabilities.
Innovation Solution
A slide-type sun visor structure that includes a slide assembly with a rail, slot screen, and cover, utilizing a ball screw, slide retainer, and rotary link to move the visor along a groove, coupled with an electromagnet module for secure attachment, allowing manual or automatic operation and incorporating a screen member and mirror for versatile shading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the sun visor is moved from the side to the front using a structure, then the sun visor can block sunlight from the front windshield, but the sun visor interferes with the driver's head and is inconvenient to use
Solution Approach 1:
The sun visor is relocated from the traditional side-mounted position to the front windshield area, changing the spatial dimension of deployment. This allows the visor to block sunlight from the front while being positioned away from the driver's head space, resolving the interference issue while maintaining shading effectiveness
2Adaptability or versatility
If the sun visor is assembled to a roof rail using screws and stored in a headlining, then the sun visor can be manually moved to prevent sunlight, but when applied to panoramic windshields, it cannot provide a roof rail or create space in the headlining
Solution Approach 1:
The sun visor system extracts itself from the traditional roof rail and headlining storage configuration. By positioning the visor at the front windshield area with a separate mounting structure, it becomes compatible with panoramic windshields that lack traditional roof rails and headlining spaces, while maintaining manual adjustability functionality
Solution Approach 2:
The sun visor design achieves universality by being adaptable to both traditional and panoramic windshield configurations. The front-mounted positioning and independent structure allow it to function across different vehicle types without requiring vehicle-specific roof rails or headlining modifications
3Object-affected harmful factors
If a sun visor structure is used to block sunlight from panoramic windshields, then the shading capability is improved, but the rail portion mounted to the side surface is exposed causing deterioration in appearance
Solution Approach 1:
The mounting structure is extracted from the visible side surface area and repositioned to the front windshield area. This relocation eliminates the exposure of rail portions on the side surfaces, improving aesthetic appearance while maintaining the sun visor's effectiveness in blocking sunlight from panoramic windshields
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
The solution enables the sun visor to block sunlight from both the front and side of the vehicle, prevent head interference, and maintain aesthetic appeal by hiding the rail, enhancing user convenience and marketability.

AI summary
Disclosed is a slide-type sun visor structure including a sun visor stored in a side surface of a vehicle when not used and pulled out toward a windshield when used, and a slide assembly fixed to the side surface of the vehicle and having formed therein a storage box in which the sun visor is stored, wherein the storage box has formed therein a groove in a length direction, and wherein the sun visor rotates while moving along the groove in the slide assembly and then moves to a position corresponding to the windshield.
