Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles, particularly trucks, are prone to flipping over due to the side force generated by vertical wind, which existing technologies have not adequately addressed.
Innovation Solution
A device comprising a rotating wind deflector part, hooks, and springs that deflects vertical side wind to a horizontal direction, adjusting its position in response to wind velocity to manage the force effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a fixed wind deflector is used to block vertical side wind, then wind deflection capability is improved, but vehicle stability deteriorates due to increased horizontal force during high-speed conditions
Solution Approach 1:
The wind deflector is designed to rotate around a horizontal axis, transitioning between a first position (parallel to vehicle body) and a second position (angled away from body). This dynamic adjustment allows the deflector to adapt to different wind conditions, reducing vertical force during normal operation while minimizing horizontal force during high-speed conditions, thereby resolving the contradiction between wind deflection capability and vehicle stability.
2Object-affected harmful factors
If a rotating wind deflector is used to optimize wind deflection, then wind deflection capability is improved, but device complexity increases due to addition of rotation mechanism, hooks, and springs
Solution Approach 1:
The wind deflector system uses wind pressure itself to drive the rotation mechanism. When vertical side wind acts on the deflector, the pressure automatically rotates it to the optimal angle without requiring external power sources, sensors, or complex control systems. The hooks and springs provide passive mechanical locking and return functions, further simplifying the overall system while maintaining effective wind deflection capability.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device reduces the vertical force on vehicles, thereby minimizing the risk of flipping over by optimizing wind deflection and stabilization, especially during high-speed conditions.
Implementation Method 1
springs part. The deflector part deflects wind from a vertical direction facing the vehicle body to a horizontal direction moving among the vehicle body surface. At a primary position the deflector part laying parallel to the body surface of the vehicle, the springs are squeezed, and the hooks are locking the deflector part. At a secondary position, the deflector part upper side is pushed away from the body surface of the vehicle, the springs are freed

AI summary
The present invention is a device that deflects or changes the direction of vehicle's vertical side wind, hence reducing the generated force, which prevents vehicle's flipping over caused by this side wind. This device consists of three parts: a deflector part comprising multiple deflector blades and deflector axis shaft. And a hook part comprising a hook piece, a hook blade piece, and a hook axis shaft. And a spring part. the deflector device has a primary position and a secondary position; in primary position the deflector part's plane is parallel to vehicle's side surface plane and hook piece is locking deflector part and spring part is squeezed; in secondary position high wind velocity rotates hook part away from deflector part, hence freeing the spring so it extends and pushes the deflector part away from vehicle's side surface, hence increases space between them, hence facilitates air flow and wind deflection.
