Convertible Air Deflector Rear Wing Wind Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Convertible cars experience significant air turbulence and noise in the back seat area when driving with the top down, as existing windblockers primarily focus on reducing turbulence for front seat occupants, leaving rear seat passengers exposed to wind drafts and noise.
Innovation Solution
An air deflector designed to attach to the upper windshield crossbeam of a convertible vehicle, featuring a top surface, outer side portion, inner side portion, and rear wing portion, with a locking device that integrates with the retractable top's locking mechanism, guiding wind upwards to reduce turbulence and noise in the rear seat area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a fixed windblocker structure is used, then turbulence reduction is effective, but ease of installation and removal decreases
Solution Approach 1:
The air deflector incorporates a locking device that enables dynamic installation and removal while maintaining fixed-position performance when installed. The locking mechanism engages with the retractable top's locking arrangement, providing a secure fixed installation that effectively reduces turbulence. When not in use, the deflector can be easily removed or detached, transforming from a fixed structure to a portable component, thus balancing effectiveness with operational flexibility.
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
The air deflector effectively reduces wind turbulence and noise in the rear seat area by guiding wind upwards, enhancing passenger comfort and reducing noise pollution, while being easy to fasten and remove, and can be made from rigid or foldable plastic materials for stability and storage convenience.
Implementation Method 1
The air deflector is adapted to direct wind from the back seat area of a convertible passenger car
