Guide Profile Combination for Window Roller Shutter Box

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing guide profile combinations for window roller shutter boxes with external inspection hatches are visually and economically inefficient due to the need for multiple parts, including separate aluminum and plastic profiles, which results in a non-uniform external appearance and increased part variety.

Innovation Solution

A guide profile combination that uses a plastic structural profile with clip-on aluminum roller shutter guide rail profiles, which cover all visible surfaces, allowing for a uniform external view and reducing the number of individual parts, and includes an integrated recess for additional guide rails for insect protection without additional sealing or screwing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of repair

If separate construction profiles and roller shutter guides are used, then the roller shutter guide can be removed for overhaul, but the visual appearance is disrupted and part variety increases

Engineering Contradiction:

Improveroller shutter guide removabilityVSAvoidpart variety

Core Design Contradiction:

Ease of repairVSDevice complexity

Solution Approach 1:

The patent combines the construction profile and roller shutter guide into a single integrated guide profile that is attached directly to the window frame. This eliminates the need for separate construction profiles and roller shutter guides, reducing part variety while maintaining the ability to remove and replace the guide profile for maintenance.

Inventive Principle:

Principle #5Merging (Combining)

2Shape

If construction profiles are produced in multiple colors and coatings to match frame surfaces, then visual uniformity is achieved, but manufacturing complexity and cost increase

Engineering Contradiction:

Improvesurface appearance uniformityVSAvoidprofile production variety

Core Design Contradiction:

ShapeVSEase of manufacture

Solution Approach 1:

The guide profile is designed with a local quality approach where the visible surfaces are specifically engineered to match the window frame appearance, while the functional internal structure remains standardized. This allows visual uniformity to be achieved without producing multiple variants of the entire profile, reducing manufacturing complexity.

Inventive Principle:

Principle #3Local quality

3Adaptability or versatility

If aluminum guide rail profiles are placed on plastic construction profiles, then aluminum windows can be equipped with roller shutters, but the visual appearance is disrupted

Engineering Contradiction:

Improvecompatibility with aluminum windowsVSAvoidvisual uniformity

Core Design Contradiction:

Adaptability or versatilityVSShape

Solution Approach 1:

The guide profile employs composite material construction with an aluminum extrusion that integrates both the guide rail function and the visible surface appearance. This single aluminum component serves dual purposes: providing the mechanical guide function and maintaining visual uniformity with aluminum window frames, eliminating the need to place aluminum profiles on plastic construction profiles.

Inventive Principle:

Principle #40Composite materials

4Reliability

If additional sealing and screwing operations are required for guide rail profiles, then secure attachment is achieved, but installation complexity and time increase

Engineering Contradiction:

Improveattachment securityVSAvoidinstallation simplicity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The guide profile incorporates self-service features including integrated mounting elements and self-aligning attachment mechanisms that eliminate the need for additional sealing operations and lateral screwing. The profile is designed to attach directly to the window frame in a simplified manner while maintaining secure attachment, reducing installation complexity and time.

Inventive Principle:

Principle #25Self-service

AI summary

Guide profile combination (101) for a window with a roller shutter box with an external inspection hatch, comprising at least a superstructure profile (110) designed as a hollow plastic profile, which is to be connected to a frame (200) or a mullion, and a guide rail profile (120) which has at least one guide rail (121) for a curtain, wherein the superstructure profile (110) and the guide rail profile (120) are interlockable; The visible surfaces of the superstructure profile (110) facing away from the frame (200) or mullion are completely covered by the guide rail profile (120). The mounting profile (110) has at least one guide rail recess (111) for a second curtain in a profile section intended for mounting on the frame (200) or center post, which additional guide rail recess (111) of the mounting profile (110) is covered by a profile section adjoining the guide rail (121).
