Venturi Wing for Motorcycle Windshield Air Displacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Open-air vehicle windshields, such as those on motorcycles, create turbulence and obstruct the rider's view due to the way air flows over the top edge, with existing solutions failing to effectively channel air beyond the windshield's height and reduce buffeting.
Innovation Solution
A transparent windshield with a concave component and solid, parallel connectors forms a venturi channel that directs air over the top edge, raising it by 2-4 inches above the standard windshield height, reducing turbulence and allowing unobstructed viewing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a windshield is installed to protect the rider from wind and weather, then protection from wind and road debris is improved, but visibility is worsened due to the windshield obstructing the view and creating turbulent air
Solution Approach 1:
The patent introduces a vertical dimension to air flow management by positioning the venturi effect generation area above the windshield surface. The wing element is placed at a specific height range (0.5-2 inches) above the windshield, creating a three-dimensional air displacement pattern that channels air over the rider's head rather than directly at the windshield, thus maintaining protection while improving visibility.
Solution Approach 2:
The venturi effect acts as an intermediary mechanism between the oncoming air and the rider. By creating a low-pressure zone through the wing element positioned above the windshield, the system mediates the air flow to redirect it smoothly over the rider's head, eliminating turbulent buffeting while maintaining the windshield's protective function.
2Object-affected harmful factors
If the windshield top edge is positioned at a specific height for protection, then wind protection is improved, but air turbulence is worsened as air flows over the top edge creating buffeting
Solution Approach 1:
The patent applies preliminary anti-action by creating a low-pressure zone above the windshield surface before the air reaches the top edge. The wing element positioned at 0.5-2 inches above the windshield generates this low-pressure zone in advance, which prevents the formation of turbulent air flow at the windshield edge by establishing smooth flow patterns beforehand.
Solution Approach 2:
The patent utilizes pneumatic principles by employing the venturi effect to manipulate air flow. The wing element creates a pressure differential that channels air smoothly over the rider's head, using aerodynamic pressure differences to control fluid flow and eliminate turbulent buffeting at the windshield edge.
3Object-affected harmful factors
If a transparent barrier is used to protect the rider, then protection from wind and debris is improved, but the ability to view the road is worsened due to the barrier being in the line of sight
Solution Approach 1:
The patent resolves this contradiction by operating in a different vertical dimension. Instead of blocking the rider's horizontal line of sight, the system acts above the windshield surface at a height of 0.5-2 inches, creating air displacement in the vertical dimension that allows the rider to view over the windshield without obstruction while maintaining protection.

AI summary
An add-on implement for an open-air vehicle windshield to allow for suitable protection and viewing therethrough while simultaneously forcing blown air over the driver's/rider's/passenger's sight line is provided. Such a device includes a wing that produces a venturi effect when placed a specific range of distances from the windshield's outer surface and having a certain height range relative to the windshield. The venturi action sends air over the top of the windshield as much as four inches higher than a normal open-air vehicle windshield, thereby allowing the driver, etc., the ability to see well over the windshield without the problem of turbulent air in his or her face or on top of his or her head. The device is adjustable to permit the driver on-demand modification of wind displacement height. An open-air vehicle (again, such as a motorcycle) including such a device is also encompassed herein.
