Solution Overview

Problem

The installation of windows in roof constructions is complicated due to the need for precise positioning and climate-proof transitions, especially when replacing existing linings or components, which requires handling multiple components and accommodating various sizes and angles, posing challenges in achieving tightness and aesthetic appeal.

Innovation Solution

A window system with a pre-installed lining support arrangement that allows for flexible installation by accommodating window linings at different angles, featuring a lining support arrangement with longitudinally extending members and an underfelt collar for climate-proofing, and a flashing assembly for weather-tight transitions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a traditional window lining installation method is used, then the window can be installed in the roof construction, but the installation process becomes complicated requiring multiple components and steps

Engineering Contradiction:
Improveinstallation processVSAvoidnumber of components
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines the lining support arrangement, underfelt collar, and flashing assembly into a single integrated pre-assembled unit that is pre-mounted to the window frame. This merging of multiple separate components into one unified assembly simplifies the installation process by reducing the number of separate parts that need to be handled and installed individually.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The lining support arrangement, underfelt collar, and flashing assembly are pre-assembled and pre-positioned on the window frame before the window is installed in the roof construction. This preliminary preparation allows the entire transition assembly to be installed in a single operation, eliminating the need for on-site assembly of multiple components and reducing installation complexity.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If the window lining is fixed at a specific angle, then the installation is simplified, but the adaptability to different installation situations is reduced

Engineering Contradiction:
Improveaccommodation of various anglesVSAvoidlining support arrangement
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The lining support arrangement incorporates an adjustable support member that can be positioned at different angles relative to the window frame. This dynamic adjustment capability allows the lining to be accommodated at various angles depending on the specific installation situation, providing versatility while maintaining a relatively simple support structure.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The lining support arrangement is divided into separate functional components including a support member with adjustable positioning, a lining panel, and connection elements. This segmentation allows each component to be independently adjusted or replaced, enabling adaptation to different installation angles without requiring complete redesign of the entire assembly.

Inventive Principle:
Principle #1Segmentation

3Shape

If the transition between window frame and inner wall is not smooth, then the construction is simpler, but the aesthetic appearance is compromised

Engineering Contradiction:
Improvesmooth transition appearanceVSAvoidlining fabrication
Core Design Contradiction:
ShapeVSEase of manufacture

Solution Approach 1:

The lining panel serves multiple functions: it provides the aesthetic smooth transition between the window frame and inner wall, while simultaneously serving as a structural element that integrates with the pre-assembled transition arrangement. This multi-functionality allows a single component to achieve both aesthetic and structural requirements without requiring additional separate elements.

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

4Reliability

If climate-proofing and weather-tightening are not prioritized, then the installation is simpler, but the comfort and weather-tight transition are compromised

Engineering Contradiction:
Improveclimate-proof transitionVSAvoidtransition assemblies
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The underfelt collar and flashing assembly are integrated with the lining support arrangement as a pre-assembled unit. The underfelt collar provides climate-proofing by creating a weather-resistant barrier between the window and roof construction, while the flashing assembly ensures weather-tight transitions. By combining these functional elements into one pre-assembled package, the patent achieves reliable climate-proofing without requiring complex on-site assembly of separate weather-protection components.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The window (1) has a supply condition and a mounted condition in a roof construction. To form a transition between the window (1) to the interior, a first transition assembly is provided in the form of a lining support arrangement (5) connected to the frame (3) of the window (1) in its supply condition. The lining support arrangement (5) has a number of longitudinally extending lining support members (51-54) to form a frame-shaped structure connected to the frame (3) in the supply condition and the support means of the lining support arrangement (5) is provided by a lining engagement portion (535) of each lining support member (51-54), formed as longitudinal bead having a part-cylindrical cross-sectional shape.
