Window Ventilation Module Pivot Connection Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The location of ventilation passages in existing roof windows within the sash restricts the space available for window panes, reducing the total light admitting area and complicating the manufacturing process due to visible pivot connections.
Innovation Solution
The ventilation flap is pivotally connected to a separate ventilation module rather than the sash, simplifying the manufacturing process and enhancing aesthetic appeal by making the pivot connection less visible.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the ventilation passage is incorporated into the window sash, then the ventilation function is integrated, but the space available for the window pane is reduced
Solution Approach 1:
The ventilation system is divided into a separate ventilation module that can be attached to the window sash, rather than integrating it directly into the sash structure. This segmentation allows the window pane area to be maximized while the ventilation module provides the ventilation function externally.
Solution Approach 2:
A separate ventilation module acts as an intermediary component between the window sash and the ventilation flap. This module provides mounting surfaces and structural support, enabling the ventilation function without compromising the window pane area.
2Area of stationary object
If a separate ventilation module is used, then the light admitting area is increased, but the manufacturing process becomes more complex
Solution Approach 1:
By segmenting the ventilation system into a separate module, the manufacturing of the window sash itself is simplified as it no longer requires internal routing for ventilation passages. The ventilation module can be manufactured separately and attached, dividing the manufacturing complexity into manageable, independent components.
Solution Approach 2:
The ventilation module is designed with pre-formed mounting features and coupling mechanisms that simplify assembly. The module comes prepared with attachment surfaces and connection points, reducing on-site manufacturing complexity and enabling easier integration with the window sash.
3Ease of operation
If the ventilation flap is pivotally connected to the sash, then the ventilation control is direct, but the pivot connection is visible and reduces aesthetic appeal
Solution Approach 1:
The ventilation module serves as an intermediary that conceals the pivotal connection mechanism. The flap connects to the module rather than directly to the visible sash, hiding the pivot joint within or behind the module structure, thus maintaining aesthetic appeal while preserving operational functionality.
Solution Approach 2:
The pivot connection is relocated from the visible face of the sash to the rear or side surfaces of the ventilation module. This dimensional relocation moves the mechanical connection to a less visible dimension, preserving the clean aesthetic lines of the window from the interior view.

AI summary
A window comprising a frame; a sash (2) mounted in the frame; a ventilation module (20) attached to or abutting with an outer peripheral surface of the sash and defining at least one ventilation passage through the window; and a ventilation flap (30) pivotally connected to the ventilation module (20).
