Automobile Window Cover with Tab Insertion Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window covers for automobiles are inconvenient to attach and can become twisted or entangled when doors are opened or closed, posing difficulties in workability and ease of use.
Innovation Solution
A window cover system with integrated front and side sheets, where plate-shaped tabs are fixed to the rear edge of the side sheets and inserted into clearances between the door glasses and the vehicle body, allowing easy attachment without opening doors, and featuring multiple tabs for stability and easy folding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the window cover is attached with doors open (using clips held between door sashes and glasses), then the cover can be fixed to cover windshield and door glasses, but the cover may get twisted or entwined when doors are opened or closed, deteriorating workability
Solution Approach 1:
The window cover is divided into a front sheet for the windshield and a pair of side sheets for the door glasses, with each side sheet having independent tabs. This segmentation allows each side sheet to be fixed independently to the vehicle body, preventing twisting and entanglement during door operations while maintaining reliable fixation.
2Reliability
If the window cover uses stopper members attached inside the vehicle compartment held between doors and body, then the cover can cover windshield and door glasses, but it becomes difficult for occupants to perform manipulation from outside, and requires exiting the vehicle, impairing convenience
Solution Approach 1:
Instead of attaching the window cover from inside the vehicle compartment as in prior art, the present invention enables attachment from outside the vehicle by inserting tabs into clearances between the door glasses and vehicle body members. This inversion of the attachment approach allows occupants to easily secure the cover without entering or exiting the vehicle.
3Reliability
If multiple tabs are provided on side sheets, then stable fixation is achieved, but device complexity increases
Solution Approach 1:
Multiple tabs are provided only at specific locations on the side sheets where fixation is needed, rather than uniformly across the entire structure. This localized approach provides stable fixation through multiple attachment points while keeping the overall structure simple and avoiding unnecessary complexity.

AI summary
A window cover for an automobile integrally includes: a front sheet to cover an outer surface of an automobile windshield; and a pair of side sheets to cover outer surfaces of left and right front door glasses, respectively. The side sheets are fixed to a vehicle body by a fixing device. The device includes a plate-shaped tab fixed to a rear edge of each side sheet. The tab is fixed by being inserted into a clearance between a rear edge of each of the front door glasses and a front edge of a rear door glass of a rear door placed rearward of the rear edge. Accordingly, convenience is improved because the cover can be easily attached to the vehicle body with the front and rear doors remaining closed, and workability is not deteriorated because the cover is not twisted or entwined when the front doors are opened or closed.
