Vehicle Window Screen Frame With Compact Retractable Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window screening solutions for vehicles, such as camper vans and motorhomes, are bulky, prone to breakage, and require multiple devices for different window shapes, occupying valuable space and risking loss when not in use.
Innovation Solution
A device comprising a stably engaged frame with a retractable screen and rail system, allowing adaptation to various window shapes, with a containment compartment for storage and a concertina design for compactness, featuring a connecting rod and bracket for easy operation and reduced complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If detachable screening fabrics or curtains are used, then the screening function is provided, but the screens occupy valuable cabin space and risk being lost when not in use
Solution Approach 1:
The screening device is merged with the vehicle body structure through a frame stably engaged with the vehicle. The containment compartment is integrated into this frame structure, combining storage and framing functions into a single integrated system that eliminates the need for separate storage space in the cabin.
Solution Approach 2:
The device provides self-contained storage through the containment compartment that is part of the screening system itself. When the screen is retracted, it automatically stores within its own structural framework rather than requiring external cabin storage space.
2Reliability
If fixed screening devices with counterframes are used, then the screens are stable and can be stored to the side, but the structure becomes bulky and more prone to breakages
Solution Approach 1:
The screen is designed as a flexible retractable element that can be stored within the containment compartment. This flexible membrane approach replaces bulky rigid counterframes while maintaining screening functionality and stability when deployed.
Solution Approach 2:
The screening system transitions from static rigid structures to a dynamic retractable mechanism. The screen can be extended when needed and retracted into the containment compartment when not in use, providing stability during operation while minimizing structural bulk during storage.
3Adaptability or versatility
If different screening devices are used for different window shapes, then each window type is properly screened, but the device complexity and cost increase
Solution Approach 1:
The frame structure with containment compartment is designed as a universal base that can accommodate screens of various shapes and sizes. The standardized frame and containment compartment design can serve multiple window configurations, eliminating the need for completely different devices for each window type.
