Solution Overview

Problem

Traditional roof window systems face challenges in achieving a flexible design and uniform appearance, especially when space is limited within the frame structure for the operator, and existing solutions do not effectively conceal the operator from view or weather exposure.

Innovation Solution

The operator is positioned externally on the side of the frame member, connected to the bracket arrangement, allowing load transfer directly to the roof structure without absorbing it within the frame, and housed between adjacent bracket units for concealment and easy maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the operator is embedded in the frame structure, then the operator is concealed from view, but the frame structure requires additional space and reduces design flexibility

Engineering Contradiction:

Improvedesign flexibilityVSAvoidframe structure complexity

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

The operator is extracted from the frame structure and mounted externally on the exterior side of the first frame member. This removes the space requirement from the frame structure while maintaining the concealed appearance from the interior side, thereby resolving the contradiction between design flexibility and operator concealment.

Inventive Principle:

Principle #2Taking out (Extraction)

2Ease of manufacture

If the operator is mounted externally on the frame member, then design flexibility is improved, but the operator becomes visible and exposed to weather

Engineering Contradiction:

Improvedesign flexibilityVSAvoidweather exposure

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The operator is positioned on the exterior side of the first frame member, which has different quality requirements than the interior side. The exterior side accommodates the operator mounting while the interior side maintains a clean, concealed appearance. This local differentiation resolves the contradiction between design flexibility and weather protection.

Inventive Principle:

Principle #3Local quality

3Strength

If the operator is connected to the bracket arrangement, then load transfer to roof structure is improved, but the connection complexity increases

Engineering Contradiction:

Improveload transfer capabilityVSAvoidconnection complexity

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

The operator is connected to the bracket arrangement that is already part of the window system for supporting the sash structure. By merging the operator's load path with the existing bracket arrangement, the system achieves improved load transfer to the roof structure without adding separate complex connection mechanisms.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

The window system has a frame structure including a plurality of frame members, a sash structure carrying a pane element and including a plurality of sash members, and an operator including an operator member having a first and a second end and adapted to extend between the frame structure and the sash structure, said frame structure being adapted to be installed in a roof structure by means of a bracket arrangement. The operator is mounted on the external side of a first frame member, and is connected to the bracket arrangement of the window system.
