Solution Overview

Problem

The existing methods for installing and removing screen rollers in rolling screen devices are labor-intensive, especially for long or heavy designs, requiring tilting and increasing the need for workforce and time when dealing with multiple devices.

Innovation Solution

A lateral guide system with a frame profile and screen profiles that allows for simplified installation and removal by providing a longitudinal installation passage accessible from multiple directions, eliminating the need to tilt the screen roller and enabling parallel insertion, thus reducing the effort required for installation and removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the traditional tilting method is used to install screen rollers, then the screen roller can be secured in the frame, but the installation process becomes more work intensive and time-consuming

Engineering Contradiction:
Improvesecure mounting of screen rollerVSAvoidinstallation speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The lateral guide is divided into two separate components: a frame profile that forms the installation passage and screen profiles that form the retention passage. This segmentation allows the installation passage to be accessible from multiple directions while the retention passage remains enclosed, enabling quick installation without tilting while maintaining secure mounting.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The installation passage is designed to be accessible from multiple directions (front, side, rear), adding dimensional accessibility to the installation process. This allows installers to approach from any convenient direction and insert the screen roller horizontally without tilting, dramatically improving installation speed while maintaining reliability.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If the traditional tilting method is used for long or heavy screen rollers, then the screen roller can be installed, but the physical effort and workforce required increase significantly

Engineering Contradiction:
Improvesecure mounting of screen rollerVSAvoidease of installation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

By separating the lateral guide into frame profile and screen profiles, the system creates an open installation passage that allows horizontal insertion of heavy rollers without tilting. This segmentation eliminates the need for difficult positioning maneuvers, making installation as easy as sliding the roller into place from any direction.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of requiring the installer to tilt the roller at an angle to fit it into the frame, the passage is inverted to be accessible from the front and sides. This allows the roller to be inserted horizontally in the natural installation direction, completely reversing the traditional difficult approach into an easy one.

Inventive Principle:
Principle #13The other way round (Inversion)

3Reliability

If multiple screen devices must be installed or removed, then the task must be completed, but the time and workforce requirements increase quickly

Engineering Contradiction:
Improvesecure mounting of screen rollerVSAvoidinstallation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The segmented lateral guide design with separate installation and retention passages allows for rapid installation and removal cycles. Each device can be quickly installed by simply sliding the roller into the accessible installation passage and secured when the screen profile is engaged, without time-consuming tilting or positioning maneuvers.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The frame profile is pre-configured with the installation passage accessible from multiple directions, and the screen profiles are pre-positioned to form the retention passage. This preliminary arrangement eliminates the need for on-site adjustments or complex maneuvers during installation, allowing rapid deployment of multiple devices.

Inventive Principle:
Principle #10Preliminary action

4Device complexity

If the lateral guide requires access from specific directions for installation, then the structure can be simple, but the adaptability to different installation positions is reduced

Engineering Contradiction:
Improvestructure of lateral guideVSAvoidinstallation position flexibility
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

By dividing the lateral guide into frame profile and screen profiles with distinct functions, the system achieves both structural simplicity and installation flexibility. The frame profile provides the simple structural backbone with open access, while the screen profiles add the retention function, allowing installation from any direction without complicating the overall structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The frame profile serves multiple functions: it provides structural support, creates the installation passage accessible from all directions, and works with screen profiles to form the retention passage. This multi-functionality allows the same simple structure to adapt to various installation positions and orientations without requiring different designs.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The invention relates to a lateral guide for a screen device for a screen rollable onto and unrollable from a screen roller. The lateral guide has a frame profile extending in a longitudinal direction that defines an installation passage for allowing passage of the lateral sides of the screen roller. The installation passage opens out into at least one access opening of the frame profile orthogonal to each other and orthogonal to the longitudinal direction, and transverse directions.
