Solution Overview

Problem

The installation of roof window coverings is cumbersome due to the need to fasten multiple parts to the frame after it is already installed, requiring handling of several elements and tools.

Innovation Solution

A roof window with a locking mechanism, including brackets attached to the side frame members near the top frame member, and a fitting set with an angle bracket and intermediate member for easy attachment and detachment of the bottom frame covering, allowing for snap-locking engagement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple elements are fastened to the frame after installation, then the covering can be securely attached, but the installation process becomes troublesome and complex

Engineering Contradiction:
Improvesecure attachment of coveringVSAvoidinstallation process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The brackets are pre-attached to the side frame members before the covering is installed. This preliminary action eliminates the need to handle multiple separate fastening elements during installation, as the brackets are already in position to receive and secure the covering components.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The locking mechanism combines multiple fastening functions into a single integrated bracket structure. The bracket integrates the attachment point and locking function, reducing the number of separate elements that need to be handled and installed during the installation process.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If multiple elements and tools are handled during fastening, then reliable attachment is achieved, but installation ease is reduced

Engineering Contradiction:
Improveattachment reliabilityVSAvoidinstallation ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

By pre-attaching the brackets to the side frame members before covering installation, the system eliminates the need for installers to handle multiple separate fastening elements and tools during the actual installation process, significantly improving installation ease while maintaining attachment reliability.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The bracket structure is designed to self-secure the covering components through its integrated locking mechanism, eliminating the need for additional tools and complex manual fastening operations. The bracket itself performs the fastening function through its design features.

Inventive Principle:
Principle #25Self-service

3Stability of the object's composition

If the frame is installed into the aperture first, then the window structure is established, but subsequent covering fastening becomes difficult

Engineering Contradiction:
Improvewindow structure stabilityVSAvoidcovering fastening ease
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The brackets are attached to the side frame members while the frame is still accessible during initial assembly, before the covering needs to be installed. This timing allows the fastening structure to be prepared in advance, making subsequent covering installation easier while maintaining the structural stability of the frame.

Inventive Principle:
Principle #10Preliminary action
