Magnetic Car Rain Guard with Inclined Shield
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional window visors fail to effectively shield rain from entering vehicles when parked, leading to poor ventilation, fuel wastage, and aesthetic issues, while also posing safety concerns due to noise and potential detachment during driving.
Innovation Solution
A car rain guard with a magnetic attach portion and inclined shield portion made of flexible rubber and plastic, allowing easy assembly and disassembly without adhesive residue, providing enhanced rain protection and ventilation by securely attaching to the car body using magnetic members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a conventional window visor is installed on the car, then rain protection is provided, but the window opening is limited leading to poor ventilation
Solution Approach 1:
The rain guard is designed to be movable and adjustable along the car window, allowing dynamic positioning to optimize both rain protection and window opening size for ventilation. The guard can slide to different positions rather than being fixed, enabling users to balance protection and airflow needs.
Solution Approach 2:
The rain guard is divided into multiple segments or sections that can independently adjust, allowing parts of the window to remain open for ventilation while other sections provide rain protection. This segmentation enables selective coverage rather than requiring the entire window to be covered.
2Object-affected harmful factors
If a window visor is installed on the car, then rain protection is provided, but loud wind noise is created while driving at high speed
Solution Approach 1:
The rain guard incorporates aerodynamic design parameters and can be adjusted to different angles and positions to optimize airflow around the window. By changing the geometric parameters of the guard's shape and orientation, wind noise is reduced while maintaining rain protection effectiveness.
3Object-affected harmful factors
If a window visor is installed on the car, then rain protection is provided, but the blind area caused by the A-pillar is increased
Solution Approach 1:
The rain guard is designed to be adjustable and movable rather than fixed, allowing it to be positioned to minimize obstruction of the driver's view. The dynamic positioning capability enables the guard to be moved away from critical viewing angles while still providing rain protection.
4Reliability
If adhesive is used to install the window visor, then secure attachment is achieved, but adhesive residue is left after removal causing aesthetic issues
Solution Approach 1:
The patent replaces chemical adhesive bonding with a magnetic attachment system. Magnets embedded in the rain guard interact with ferromagnetic materials on the car body to provide secure attachment without requiring adhesives. This mechanical/magnetic system allows for clean removal without leaving any residue, maintaining aesthetic appearance.
5Object-affected harmful factors
If a window visor is installed on the car, then rain protection is provided, but the visor may come off easily affecting driving safety
Solution Approach 1:
The magnetic attachment system provides strong holding force through magnetic attraction between the rain guard's magnetic members and the car body's ferromagnetic surface. This magnetic force is sufficient to secure the guard against vibration, wind pressure, and accidental contact, preventing detachment while allowing intentional removal when needed.
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 car rain guard effectively prevents rain from entering the vehicle, maintains good ventilation, and ensures secure attachment without leaving residue, improving driving safety and aesthetics by allowing wider window openings and reducing wind noise.
Implementation Method 1
The magnetic member is arranged at the attach portion of the rain shield so that the attach portion can be attached to and sealed on the surface by magnetic force detachably

AI summary
A car rain guard which includes a rain shield and at least one magnetic member. The rain shield consists of an attach portion and a shield portion integrally extended from the attach portion. The attach portion is attached firmly to a surface above at least one door of a car body. An angle is formed between the attach portion and the shield portion so that the shield portion can be inclined from an inner side to an outer side to repel rain and drain water. The magnetic member is disposed on the attach portion of the rain shield so that the attach portion can be attached to and sealed on the surface detachably by magnetic attraction. Thereby the window can be left down enough, without worrying about rain splashing into the car. The rain guard is applied to a stopped car with an off engine.
