Insulated Pane Ventilation Layout Without Frame Modification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing decentralized ventilation systems integrated into windows compromise the insulation capacity of multiple glazing and aesthetics, as they often require complex structural changes or compromise sealing integrity.
Innovation Solution
A ventilation device is embedded within the pane arrangement at a distance from the insulation volume, utilizing the space created by setting back the edge seal to accommodate a larger heat exchanger and radial fans, with an insulating body made from polystyrene foam to maintain insulation and a flat design, and optionally powered by a solar element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the ventilation device is integrated into the window frame, then the ventilation function is achieved, but the window area is reduced and appearance is deteriorated
Solution Approach 1:
The ventilation device is nested within the space created by setting back the edge seal between the panes of glass. The device is positioned in the free space formed when the edge seal is set back from the outer surface of the first pane, allowing the ventilation function to be integrated without reducing the visible window area or compromising appearance.

3Ease of operation
If the ventilation device is arranged in the passage opening by breaking through the pane arrangement, then the ventilation function is achieved, but the insulation capacity is compromised
Solution Approach 1:
The ventilation device is nested within the space created by setting back the edge seal between the panes of glass. The device is positioned in the free space formed when the edge seal is set back from the outer surface of the first pane, allowing the ventilation function to be integrated without reducing the visible window area or compromising appearance.
Solution Approach 2:
An insulating body extending from the edge seal to the first pane serves as an intermediary element. This insulating body fills the space between the ventilation device and the insulating volume, preventing thermal bridges and maintaining the insulation capacity of the multiple glazing while allowing the ventilation device to function.
4Productivity
If a larger heat exchanger is installed, then the ventilation efficiency is improved, but the space requirements increase
Solution Approach 1:
The edge seal is set back from the outer surface of the first pane, creating additional three-dimensional space between the panes. This dimensional change in the positioning of the edge seal provides sufficient volume to accommodate a larger, more efficient heat exchanger without increasing the external dimensions of the window assembly.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution maintains the insulation capacity and aesthetic appeal of multiple glazing while allowing for efficient ventilation without requiring structural changes to the window frame, using the space between panes for the ventilation device and insulating body, and providing self-sufficient energy through a solar element.
Implementation Method 1
as a result of which a particularly flat design is possible. Provision is particularly preferably made for exactly two radial fans to be provided.
Implementation Method 2
Another advantage is that it is possible to install a larger and therefore more efficient heat exchanger.
Implementation Method 3
the at least one fan and the heat exchanger are arranged in an insulating body. This insulating body can be made from extruded rigid polystyrene foam (XPS) and/or expanded rigid polystyrene foam (EPS)
Implementation Method 4
a solar element—preferably a photovoltaic element—is arranged on the pane arrangement
