Vehicle Visor Sleeve Extension for Light Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle visors often fail to adequately block sunlight due to size limitations, and existing extension devices can damage the visor, are difficult to install, or require complex mounting systems that reduce resale value and effectiveness over time.
Innovation Solution
A vehicle visor accessory device with a sleeve structure that removably mounts on the visor, featuring a notch and extension structure to increase light-blocking coverage without damaging the visor or requiring complex mounting, allowing easy installation and removal for use on different vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If existing extension devices are used to increase visor coverage, then light-blocking capability is improved, but the visor may be damaged or the mounting system becomes complex
Solution Approach 1:
The extension device is designed to slide over and nest around the existing visor structure, with the visor passing through the hollow interior of the sleeve structure. This nested configuration allows the extension to increase coverage area without requiring complex mounting systems or causing damage to the original visor.
Solution Approach 2:
The sleeve structure acts as an intermediary between the visor and the extension structure, providing a protective interface that prevents direct contact and potential damage between components while enabling the extension to function effectively.
2Reliability
If complex mounting systems are used to attach extension devices, then extension stability is improved, but installation difficulty and resale value reduction increase
Solution Approach 1:
The extension device is segmented into distinct functional components: a sleeve structure for mounting over the visor, an extension structure for providing additional coverage, and a notch for positioning. This segmentation allows for simple snap-fit installation without complex mounting systems, maintaining ease of operation while achieving stable extension.
3Area of stationary object
If the visor size is increased to improve shading, then light-blocking capability is improved, but the visor becomes bulkier and harder to fold
Solution Approach 1:
Instead of increasing the visor size in all dimensions, the extension structure adds coverage primarily in the vertical dimension by extending downward from the sleeve structure. This allows increased shading area without significantly increasing horizontal bulk or complicating the folding mechanism.

AI summary
A vehicle visor accessory device for selectively extending shading capabilities of a visor may comprise a sleeve structure configured to removably mount on the visor. The sleeve structure may be elongated with an upper end for positioning toward the upper edge section of the visor and a lower end for positioning toward the lower edge section of the visor, and have a first opening located at a first side edge of the sleeve structure through which a portion of the visor is slidable. A notch may be formed in the sleeve structure. An extension structure may be integrated with the sleeve structure. The sleeve structure may have a substantially hollow interior between first and second faces to slidably receive at least a portion of the visor and the extension structure may have a solid interior between the faces to extend light blocking coverage of the visor.
