Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles with removable roofs or convertible tops face challenges in shielding drivers and passengers from excessive sunlight and wind-borne debris, which can be distracting and uncomfortable during operation.
Innovation Solution
A removable exterior windshield visor accessory with a front shade panel assembly and lateral end shade panels that attach to the roll cage, featuring hinged connectors and securing means to form a seal, providing shade and airflow management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a removable roof or convertible top is used to enjoy open air and unhindered view, then driving enjoyment and visibility are improved, but protection from sunlight and wind-borne debris deteriorates
Solution Approach 1:
The visor system is divided into multiple segments: a central front shade panel and two lateral end shade panels that can be independently attached to the roll bars. This segmentation allows the visor to be customized and adjusted to fit different vehicle configurations while providing comprehensive protection against sunlight and debris from multiple angles.
Solution Approach 2:
The visor incorporates hinged connectors that allow the lateral end panels to be dynamically adjusted and positioned. The hinges enable the panels to be attached at various angles to the roll bars, allowing users to optimize the shading coverage based on sun position and driving conditions while maintaining ease of installation and removal.
2Object-affected harmful factors
If a fixed visor structure is used to provide comprehensive shade, then protection from sunlight is improved, but ease of installation and removal deteriorates
Solution Approach 1:
The visor uses hinged connectors instead of fixed rigid attachments. The hinges allow the lateral end panels to be easily attached and detached from the roll bars without requiring complex fastening mechanisms or tools. Users can quickly install or remove the visor by simply connecting the hinged panels to the roll bar mounting points.
Solution Approach 2:
The visor design with universal mounting points on the roll bars and hinged connectors makes it adaptable to various vehicle types with removable roofs. The same basic design can be installed on different vehicle platforms, and the hinged panels can be positioned at various angles to accommodate different sun positions and vehicle geometries.
3Area of stationary object
If lateral end panels are added to provide side protection, then coverage area is improved, but device complexity increases
Solution Approach 1:
The visor is segmented into a central front panel and two separate lateral end panels that attach to the roll bars. This segmentation allows each panel to be independently sized and shaped to provide optimal coverage for its specific location. The modular design makes it easier to manufacture, install, and adjust compared to a single large complex structure.
Solution Approach 2:
The lateral end panels are connected via hinged joints that allow them to be positioned at optimal angles for side protection. The hinges provide the necessary degrees of freedom to adjust the panel positions without requiring complex mechanical linkages or adjustment mechanisms, thereby increasing coverage area while minimizing structural complexity.

AI summary
A vehicle exterior windshield visor accessory is provided which is configured to assist in managing some of the unwanted outdoor elements such as excessive wind and bright sunlight. In a version, the visor accessory is generally configured to be operably and attachably removable with existing and future exposed top or removable top type vehicles having a roll cage. Generally, the visor accessory includes a front shade panel assembly, a first and second lateral end shade panels, and a means for securing each end shade panel to the roll cage.
