Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automotive windshield and sunshield cover structures are ineffective in preventing damage from sunlight, rain, and snow due to their design, which allows wind to lift them off, and they are not suitable for mass production at low costs.
Innovation Solution
An automotive windshield and sunshield cover structure featuring a windshield cover with magnetic strips and extension portions that adhere tightly to the vehicle body and door receiving grooves, using a waterproof and opaque material to prevent snow and water accumulation and block sunlight, while venting air to prevent wind-induced removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fabric covers held with rods are used, then the structure is simple, but the cover is easily removed or lifted by gusts of wind, failing to protect the vehicle
Solution Approach 1:
The patent replaces the conventional mechanical rod-based attachment system with a magnetic field-based attachment system. The magnetic strips generate magnetic attraction forces that securely hold the cover against the vehicle body, providing reliable wind resistance without the complexity of mechanical rods and fasteners.
Solution Approach 2:
The patent changes the attachment mechanism from mechanical (rods and fasteners) to magnetic (magnetic strips generating magnetic field). This parameter change in the attachment method provides both simplicity and reliability, as the magnetic force can be easily controlled and adjusted while providing secure attachment.
2Reliability
If fabric covers are used without proper sealing, then the material is simple, but snow and water droplets can flow into or seep into the vehicle
Solution Approach 1:
The patent divides the sealing function into multiple segments: the main body of the cover provides primary coverage, while the first and second extension portions provide additional sealing at the sides, and the lower extension portion provides sealing at the bottom. This segmented approach achieves comprehensive sealing without requiring complex manufacturing processes.
Solution Approach 2:
The patent uses flexible extension portions made of the same fabric material that can conform to the vehicle body contours. These thin film-like extension portions effectively seal gaps and prevent water and snow ingress while maintaining manufacturing simplicity through standard fabric construction techniques.
3Temperature
If conventional open designs are used, then air circulation is good, but the vehicle interior heats up under sunlight and meters/components are damaged
Solution Approach 1:
The patent applies different qualities to different parts of the cover: the main body is made opaque to block sunlight and protect the interior, while the reticular vent portions provide localized air circulation. This local differentiation allows the cover to simultaneously achieve thermal protection and ventilation without requiring a completely complex structure.
Solution Approach 2:
The patent uses opaque material for the main body of the cover, which blocks sunlight and prevents the vehicle interior from heating up. The opaque property acts as a form of optical property change, protecting meters and components from sunlight damage while maintaining a relatively simple cover structure.
4Reliability
If the cover is designed to fit tightly, then protection is effective, but manufacturing precision requirements increase
Solution Approach 1:
The patent uses flexible fabric material for the cover and its extension portions, which can naturally conform to the vehicle body contours. This flexibility compensates for variations in vehicle body dimensions and reduces the need for high manufacturing precision, while still achieving effective tight coverage and protection.
Solution Approach 2:
The patent incorporates magnetic strips that provide dynamic attachment force, allowing the cover to adapt to slight variations in vehicle body dimensions. The magnetic force ensures consistent attachment across different vehicles without requiring precise manufacturing tolerances, maintaining both reliability and ease of manufacture.

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 solution effectively prevents snow and water from accumulating on windshields, blocks sunlight to cool vehicles, and securely attaches to the vehicle, preventing wind-induced removal, while being suitable for mass production at low costs.
Implementation Method 1
the first extension portion and the second extension portion each encloses at least one first magnetic strip, respectively, and thus adhere to door receiving grooves on two opposing sides of the vehicle, respectively
