Solution Overview

Problem

Existing methods for assembling roller shutter boxes on frames are not as safe and easy to handle as they could be, particularly in achieving a secure connection between the static and holding parts during installation.

Innovation Solution

The static part is pre-connected to the roller shutter box before installation, allowing for a snap-on connection to the holding part, with a blocking mechanism that ensures the static part is securely positioned in a displacement position, preventing movement transversely along the holding part once loaded.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the static part is inserted at an angle to achieve form-fitting connection, then the connection strength is improved, but the ease of operation deteriorates due to complex insertion procedure

Engineering Contradiction:
Improveconnection strengthVSAvoidease of installation
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The static part is pre-connected to the roller shutter box before installation, with the blocking part already positioned to guide the insertion. This preliminary preparation eliminates the need for complex angled insertion procedures during installation, allowing for simple vertical lowering while maintaining secure connection.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If the opening in the support part is narrowed to prevent release, then the reliability is improved, but the ease of operation deteriorates due to difficulty in insertion

Engineering Contradiction:
Improvesecurity of connectionVSAvoidease of insertion
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The blocking part is designed to be movable, allowing the opening width to dynamically change during installation. During insertion, the blocking part is in a first position that widens the opening for easy vertical lowering. After insertion, the blocking part moves to a second position that narrows the opening to prevent release, thus maintaining both ease of operation and reliability.

Inventive Principle:
Principle #15Dynamics

3Stability of the object's composition

If the static part is firmly connected before installation, then the stability is improved, but the device complexity increases due to additional connection steps

Engineering Contradiction:
Improvestability of roller shutter boxVSAvoidcomplexity of assembly process
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The connection between the static part and the roller shutter box is merged with the installation process itself. The static part is pre-connected to the box, and this connection is finalized during the single vertical lowering motion into the support part. This combines multiple operations into one simple action, maintaining stability without increasing perceived complexity.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A method for mounting a roller shutter box (1) on a frame part (16), such as a window or door frame, wherein a mounting part (13) is attached to the frame part (16), to which the roller shutter box (1) is snap-fitted, and wherein the mounted roller shutter box (1) is further reinforced by means of a structural element (7) that acts directly between a building wall and the mounting part (13). To provide a method for mounting a roller shutter box that enables the simplest and safest possible installation of the roller shutter box using the structural element, it is proposed that the structural element (7) be firmly connected to the roller shutter box (1) before the roller shutter box is installed, that the roller shutter box (1) with the connected structural element (7) is then snapped onto the mounting part (13) for installation of the roller shutter box (1), and that a positive-locking connection is established between the structural element (7) and the mounting part (13).The invention further relates to a roller shutter box (1) mounted on a frame part (16), wherein the roller shutter box (1) has a structural element (7). The invention also relates to a structural element (7) for connecting a frame part (16) to a building wall.
