Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional roller screen devices have encumbrance issues when the screen is wound and moved manually, as the movement systems are typically located in the sliding sectional element, making them bulky and difficult to assemble or replace.

Innovation Solution

Reversing the configuration by placing the roller in the mobile sectional element and the guiding systems in the fixed sectional element, with a tensioning system using a thread loop to manage screen opening and closing, allowing for compact and user-friendly assembly and replacement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the movement systems are located in the sliding sectional element, then the screen can be opened and closed manually, but the overall dimensions of the sliding element increase making it bulky and aesthetically less appealing

Engineering Contradiction:

Improvemanual opening and closing capabilityVSAvoidoverall dimensions of sliding element

Core Design Contradiction:

Ease of operationVSVolume of moving object

Solution Approach 1:

The patent inverts the conventional configuration by placing the roller in the mobile sectional element and the guiding systems in the fixed sectional element. This reversal allows the mobile element to be compact while still enabling manual operation through the fixed element's guiding systems.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The movement systems (guiding systems) are extracted from the mobile sectional element and placed in the fixed sectional element. This separation allows the mobile element to be minimized in size while the fixed element accommodates the bulkier guiding mechanisms.

Inventive Principle:

Principle #2Taking out (Extraction)

2Reliability

If the movement systems are located in the sliding sectional element, then the screen can be guided during opening and closing, but the device becomes difficult to assemble and replace for non-skilled persons

Engineering Contradiction:

Improvescreen guidance during operationVSAvoidassembly and replacement simplicity

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The device is segmented into distinct functional modules: the mobile sectional element containing the roller and screen, and the fixed sectional element containing the guiding systems. This segmentation allows independent assembly and replacement of components, simplifying installation and maintenance for end users.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

By inverting the conventional configuration and placing guiding systems in the fixed element rather than the mobile element, the patent simplifies the mobile element's structure, making it easier to assemble and replace as a complete module.

Inventive Principle:

Principle #13The other way round (Inversion)

3Ease of operation

If the roller is placed in the fixed sectional element, then the screen can be wound up, but the sliding sectional element becomes bulky and encumbering when moved manually

Engineering Contradiction:

Improvescreen winding capabilityVSAvoiddimensions of sliding sectional element

Core Design Contradiction:

Ease of operationVSLength of moving object

Solution Approach 1:

The patent inverts the conventional arrangement by placing the roller in the mobile sectional element instead of the fixed element. This allows the mobile element to carry the winding function while remaining compact, as the roller is integrated into its structure.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The mobile sectional element is designed to perform multiple functions: it contains the roller for winding the screen and serves as the sliding component for manual operation. This multi-functionality consolidates features that would otherwise require separate components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A roller screen device includes a fixed sectional element (10) and a mobile sectional element (11) that is able to move parallel to the fixed sectional element inside a frame contained in which is a screen (13), the mobile sectional element (11) bearing a roller (12) inside it, wound on which is the screen (13), which, at the other end, is anchored to the fixed sectional element (10). Guide elements (14 and 24) for guiding the mobile sectional element (11) are positioned at the top and at the bottom of the screen (13) and fixed at one end to the mobile sectional element (11), while the other ends of the guide elements (14) slide into the fixed sectional element (10). Moreover provided is a system for tensioning the guides (14 and 24), which acts during the steps of opening and closing of the screen (13). The tensioning system includes a thread (20), which extends starting from the end (21) of the top guide (14) that slides in the fixed sectional element (10) towards and around a bottom roller (22) and from here to the end (23) of the bottom guide (24), which slides in the fixed sectional element (10), to proceed to and around a top roller (25) and from here to the end (21) of the top guide (14) so closing to form a loop.
