Wind Deflection System with Arcuate Wing for Rider Head Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wind deflection systems for vehicles are ineffective in preventing wind from striking the rider's head, leading to fatigue and discomfort during travel.
Innovation Solution
A deflection unit coupled to the windshield of a vehicle, featuring a resiliently bendable saddle with a concavely arcuate wing that directs wind upwardly, reducing wind impact on the rider's head by being adhesive to the windshield and extending along its width.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a traditional windshield is used, then the vehicle provides basic wind protection, but wind still strikes the rider's head causing fatigue and discomfort
Solution Approach 1:
The deflection unit is divided into a saddle portion and a wing portion that are separable yet functionally integrated. The saddle portion attaches to the windshield while the wing portion extends outward to deflect wind, allowing independent optimization of each component's shape and material properties.
Solution Approach 2:
The wing portion features a concavely arcuate shape that smoothly redirects wind flow upward and away from the rider's head. The curved geometry is optimized to match aerodynamic flow patterns, creating effective wind deflection without requiring complex mechanical structures.
2Object-affected harmful factors
If a rigid deflection structure is used, then wind deflection effectiveness is high, but the structure creates turbulence and increases wind noise
Solution Approach 1:
The deflection unit is constructed from a flexible material that can elastically deform under wind pressure. This flexibility allows the structure to smoothly adapt to varying wind conditions, preventing turbulent flow separation and reducing wind noise while maintaining effective wind redirection.
Solution Approach 2:
The concavely arcuate shape of the wing portion creates a streamlined profile that guides wind flow smoothly around the rider's head. The curved geometry prevents sharp edges that would cause flow separation and turbulence, thereby reducing wind noise and improving aerodynamic performance.
3Object-affected harmful factors
If the deflection unit is made large to cover more area, then wind protection is improved, but the unit becomes more visible and aesthetically less appealing
Solution Approach 1:
The deflection unit is strategically positioned and sized to provide wind protection only in the critical area around the rider's head, rather than attempting to cover the entire windshield area. This localized approach maintains aesthetic appearance while delivering effective wind protection where it is most needed.
Solution Approach 2:
The wing portion extends outward from the windshield surface in a third dimension, creating a three-dimensional deflection structure that provides effective wind protection without increasing the two-dimensional footprint on the windshield. This spatial arrangement maintains aesthetic appearance while improving wind protection coverage.
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
Effectively redirects wind upwardly, reducing fatigue and discomfort for the rider by preventing wind from hitting the head, suitable for various types of vehicles including motorcycles and personal watercraft.
Implementation Method 1
The deflecting unit may further include an adhesive layer positioned on the inwardly facing surface of the saddle. The adhesive layer may be centrally positioned between the spaced members and may adhesively engage the top edge of the windshield.
Implementation Method 2
The saddle may be comprised of a resiliently bendable material such as rubber or the like

AI summary
A wind deflection system for deflecting wind on a vehicle includes a vehicle that has a windshield to redirect wind with respect to a rider of the vehicle. A deflecting unit is coupled to the windshield to deflect wind upwardly with respect to the rider. In this way the deflecting unit inhibits the wind from striking the rider's head.
