Screen Device Beam with Integrated Gutter and Roller Cavity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen devices face challenges in aesthetically integrating lateral sides of rollable screens with adjacent elements, and inefficient precipitation drainage requires additional connecting pieces and modifications.
Innovation Solution
A screen device design featuring a beam with an internal cavity for the screen roller, end caps with central parts for secure attachment to columns, and integrated gutter systems for precipitation drainage, allowing for aesthetic alignment and reduced additional components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If screen guides are fixed to columns of the screen device, then the lateral sides of the screen can be guided properly, but the aesthetic appearance deteriorates due to visible fixing elements
Solution Approach 1:
The screen guides are merged with the beam structure itself. The guides are incorporated into the beam's internal cavity and attached to the screen roller, eliminating the need for separate column-mounted guide fixtures. This integration maintains proper screen guidance while achieving a clean, aesthetic appearance without visible external fixing elements.
Solution Approach 2:
The screen guides are nested within the beam structure. The guides are positioned inside the beam's internal cavity and connected to the screen roller, placing the guiding mechanism within the existing structural element rather than adding external attachments to columns.
2Reliability
If additional connecting pieces are provided for precipitation drainage, then drainage functionality is improved, but device complexity increases
Solution Approach 1:
The drainage system is merged with the beam structure. The beam includes an internal cavity that serves as a drainage channel, and the end cap incorporates a passage opening that connects this internal cavity to the column cavity. This integration provides reliable precipitation drainage while eliminating the need for separate connecting pieces and additional drainage components.
Solution Approach 2:
The beam structure serves multiple functions: it provides structural support for the covering, houses the screen roller in its internal cavity, and simultaneously functions as a drainage channel for precipitation. The end cap also serves dual purposes by sealing the beam end and providing the drainage passage connection to the column.

AI summary
The present invention relates to a screen device (1), comprising: - a covering which comprises a beam (2) as a structural part, which is attachable to at least one adjacent structural part (3, 5) of the screen device (1) and which comprises an internal cavity (24), in which a screen roller of the screen device (1) is arranged; - and an end cap (6, 6') which is attachable to one end of the beam (2) in order to attach the beam (2) to the adjacent structural part (3, 5) and which comprises a central part (20) which extends at a certain distance from the beam (2) and to which the screen roller is coupled; wherein at least one through-opening (13) extends next to the end cap (6, 6'), through the end of the beam (2), such that a screen which can be rolled up onto and unrolled from the screen roller partly extends through this through-opening (13).
