Vehicle Screen Connection Device for Terrain Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen arrangements for vehicles, such as RVs, lack flexibility in deployment and adjustment after being installed, particularly on uneven terrain or slopes, and do not effectively absorb vehicle movements.
Innovation Solution
A screen arrangement with a connection device featuring a pivotally connected elongated member and a slideable second connection member, allowing for adjustable positioning and reduced transfer of movement between the screen and the vehicle, utilizing a snap-on connection and adjustable strap members for secure attachment to the vehicle and awning support legs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the screen arrangement uses a fixed connection device attached to the vehicle, then the connection is stable and secure, but the screen arrangement cannot be adjusted after deployment and does not adapt to uneven terrain or slopes
Solution Approach 1:
The connection device incorporates a slideable second connection member that can move along the elongated member, transforming a static fixed connection into a dynamic adjustable connection. This allows the screen arrangement to be repositioned after deployment to adapt to uneven terrain or slopes, while the overall structure remains relatively simple through the use of guided linear movement rather than complex mechanisms
Solution Approach 2:
The connection device is divided into multiple independent components: a first connection member attached to the vehicle, an elongated member serving as a connector, and a second connection member that interfaces with the screen arrangement. This segmentation allows each component to perform its specific function independently, enabling adjustment capability without requiring complete redesign of the entire connection system
2Reliability
If the screen arrangement is directly rigidly connected to the vehicle, then the connection is strong and stable, but vehicle movements are fully transferred to the screen causing excessive movement and instability
Solution Approach 1:
The elongated member acts as an intermediary element between the first connection member (vehicle) and the second connection member (screen). This intermediate component absorbs and dampens movement transfers from the vehicle, preventing rigid transmission of vibrations and shocks to the screen while maintaining a stable connection
Solution Approach 2:
The connection device allows for changes in positional parameters through the slideable second connection member, which can be repositioned along the elongated member. This parameter adjustment capability enables the system to adapt to varying vehicle movements and terrain conditions, maintaining screen stability despite vehicle motion
3Productivity
If the screen arrangement uses a simple attachment mechanism, then the deployment is fast and easy, but the connection lacks adjustability and flexibility for different terrains
Solution Approach 1:
The connection device employs a dynamic adjustment mechanism where the second connection member can slide along the elongated member, providing adjustability after deployment. The mechanism maintains deployment efficiency through a straightforward snap-on connection design that requires minimal steps while enabling subsequent repositioning for different terrain conditions
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
Enables easy and flexible deployment and adjustment of the screen, reducing movement transfer and simplifying the connection process, suitable for various vehicle types, especially RVs, caravans, and vans.
Implementation Method 1
the first connection member and the second connection member are pivotally connected with a pivot connection. By using a pivot connection, movement of the vehicle will not be fully transferred to the screen and movements of the screen will not be fully transferred to the vehicle
Implementation Method 2
the second connection member of the connection device is formed by a snap on connection, enabling the elongated member to be detachably connected thereto

AI summary
The present invention relates to a screen arrangement (10) for a vehicle (1) such as a wind screen arrangement, sun screen arrangement or a privacy screen arrangement. The screen arrangement (10) comprises a screen (11) displaceable between an extended position and a retracted position. The screen (11) is wound around a first bar (12). The first bar (12) is connected to a substantially parallel second bar (13) having a connection device (20) permitting the second bar (13) to be pivotally connected to the vehicle (1), while being adjustable in a direction along the length of the second bar (13). The connection device (20) thus provides for a slip, or slide, connection between the vehicle and the second bar (13) of the screen arrangement (10). The present invention provides for a screen arrangement which is easy to deploy and which permits adjustment after being deployed.
