Clip-On Visor Extension for Side Glare
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sun visors fail to provide adequate protection from side sun glare, especially when driving on curved roads, as they are not universally adaptable, easily adjustable, or inexpensive, and cannot be extended to cover the uppermost rear corner area of the side window without obstructing the rear view or driver's vision.
Innovation Solution
A clip-on car visor extension device that can be semi-permanently attached to existing sun visors, featuring a U-shaped clip member with grabber ridges for secure attachment and a translucent or opaque glare-reducing sheet element that can be swiveled outward to block side sun glare, then easily stored out of the way when not needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a retractable glare screen is integrated with the visor, then side glare protection is improved, but the device complexity increases
Solution Approach 1:
The extension panel incorporates a spring-loaded mechanism that automatically extends when pulled and retracts when released, providing dynamic functionality. This simple elastic mechanism eliminates the need for motors, sensors, or complex control systems, achieving side glare protection with minimal added complexity.
Solution Approach 2:
The spring mechanism provides self-service functionality where the extension panel automatically retracts after being pulled out, without requiring user intervention or complex control systems. The elastic potential energy stored in the spring automatically returns the panel to its stored position, simplifying the overall device architecture.
2Adaptability or versatility
If the visor extension is made universally adaptable for all vehicle models, then adaptability is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The attachment mechanism is designed with universal compatibility features, including adjustable mounting positions and flexible mounting methods that can accommodate various visor thicknesses and materials across different vehicle models. This universal design approach allows a single product to fit multiple vehicle types without requiring precision customization for each model.
Solution Approach 2:
The device incorporates adjustable parameters in its attachment system, such as variable mounting positions and flexible fastening mechanisms, that can be adapted to different visor configurations. This allows the same basic design to accommodate variations in visor dimensions and materials across different vehicle models without compromising attachment reliability.

AI summary
A clip on car visor extension for use on a vehicle's existing sun visor, effectively blocks out sunrays which the visor itself is not capable of blocking on its' own. The clip on car visor extension is made up of a clip member and a glare reducing sheet element, rotatably fastened on the clip member. The clip member has two elongated legs joined at the closed end by a connecting leg. The glare reducing sheet element is preferably rectangular shaped.The clip on car visor extension can be moved laterally or horizontally on the vehicles sun visor as needed by moving the clip member and radially rotating the glare reducing sheet element to an angle as needed depending on the user's position and sun's position in the sky.
