Screen Roller Supporting Element Sliding Guide Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of screen devices with heavy or large screen rollers in confined spaces, such as under roofs or within walls, is complicated due to the need to counteract gravity, often requiring multiple individuals and being labor-intensive, especially when the supporting element must be pushed vertically.
Innovation Solution
A screen device design featuring a rotatable screen roller with a supporting element that slides into a fixing body with guide elements, utilizing a securing element that moves between positions to secure the supporting element during installation, preventing it from sliding back and providing temporary support against gravity, and optional additional fastening elements for a strong connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the supporting element is pushed vertically upwards between the guide elements to install the screen roller counter to gravity, then the screen roller can be installed in confined spaces such as under roofs or within walls, but the installation becomes labor-intensive and requires multiple individuals to cooperate
Solution Approach 1:
The securing element is designed to automatically engage with the supporting element during the sliding movement, providing preliminary support before the installation is complete. This preliminary action eliminates the need for manual support during the critical phase of counteracting gravity, allowing single-person installation while maintaining the ability to install in confined spaces
Solution Approach 2:
The securing element acts as an intermediary between the supporting element and the guide elements. It provides a mechanical interface that temporarily bears the weight of the screen roller during installation, transferring the load from the installer to the fixing body structure, thereby reducing the physical effort required
2Reliability
If the supporting element is fastened to the fixing body by means of screws and additional auxiliary means, then a secure connection is achieved, but the installation process becomes more complex and time-consuming
Solution Approach 1:
The invention extracts the complex fastening operation from the installation process by replacing screws and auxiliary means with a simple sliding movement. The supporting element is designed with features that allow it to slide directly into the fixing body and be secured by the automatic engagement of the securing element, eliminating the need for additional fastening tools and steps while maintaining connection reliability
Solution Approach 2:
The securing element is designed to automatically engage and secure the supporting element during the sliding movement without requiring additional fastening operations. The system self-secures itself through the mechanical interaction between the securing element and the supporting element, eliminating the need for manual intervention with screws or other fastening means

AI summary
The present invention relates to a screen device, comprising a supporting element (3) on an end side of the screen roller, a fixing body (4) with two guide elements (5), between which the supporting element (3) can slide in and out via a fitting opening (6) for guiding the supporting element (3) for installation thereof and a securing element (7) which during the sliding movement during the installation of the supporting element (3) is first moved towards its second position in which the supporting element (3) can slide in and out of the guide elements (5) and is then returned to its first position, in which the securing element (7) prevents the supporting element (3) from sliding out of the guide elements (5).
