Window Ventilation Element With Transverse Sealing Slide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window and door ventilation elements often hinder the mobility of windows and doors when retrofitted, as they are designed to be installed only in the upper transverse area and cannot be attached to the sides or bottom without obstructing tilting or pivoting movements, limiting their versatility and ability to meet minimum, basic, and demand ventilation requirements.
Innovation Solution
A window or door ventilation element with a displaceable sealing slide that can be attached to any side of the sash or frame without obstructing movement, featuring a base plate with protruding limiting webs and a plate-shaped sealing slide that adjusts perpendicular to the airflow, allowing for adjustable airflow paths without requiring structural changes to the window or door.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If ventilation elements are installed in the upper transverse area of the window or door, then they can provide ventilation functionality, but they cannot be attached to the lower transverse area or sides where swivel hinges are arranged without obstructing tilting or pivoting movements
Solution Approach 1:
The ventilation element is divided into a base plate and a separate sealing slide component. The base plate is fixed to the window sash, while the sealing slide moves independently within a guide channel, allowing the ventilation opening to be controlled without interfering with window movement mechanisms.
Solution Approach 2:
The sealing slide moves perpendicular to the airflow direction (transversely) rather than blocking the airflow path. This transverse movement allows the seal to engage and disengage from the guide channel walls, enabling ventilation control while maintaining window mobility in the tilting and pivoting dimensions.
2Adaptability or versatility
If a sealing slide is arranged to be displaceable transversely to the flow direction in the area of the sash overlap seal, then the ventilation element can be attached to any side without obstructing movement, but the structure becomes more complex
Solution Approach 1:
The base plate with guide channel and transverse sealing slide creates a universal ventilation element that can be installed on any side of the window sash (upper, lower, left, or right) without requiring different designs. The same structure adapts to different installation locations while maintaining full functionality and not obstructing window movements.
3Productivity
If existing ventilation elements are designed with fixed airflow paths, then they can provide automatic minimum ventilation, but they cannot be adjusted for basic and demand ventilation
Solution Approach 1:
The sealing slide is designed to be displaceable transversely within the guide channel, allowing dynamic adjustment of the ventilation opening size. By moving the sealing slide to different positions, the airflow path cross-section can be varied, enabling adjustment between minimum ventilation (partially closed) and basic/demand ventilation (fully open or larger opening) modes.

AI summary
A baseplate has two boundary bars on the long sides. One bar positions within one of the ventilation flow paths (6b) and adjoined to the sealing region of a door or window seal. A seal slide catch provided on the baseplate is moved transverse to the air flow direction between a maximum opening position and a locked or catch position.
