Sliding Door Ventilation Profile Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding door systems and ventilation devices require visible and costly modifications to the masonry for air exchange, compromising aesthetics and increasing construction costs.
Innovation Solution
A sliding door system with a telescopically adjustable ventilation profile that integrates into the frame, allowing air exchange without visible components when closed, and can be pulled out for ventilation, featuring a U-shaped or H-shaped cross-section with adjustable openings and magnetic coupling for secure locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a ventilation grille is attached to the fixed frame or masonry, then air exchange is enabled, but the aesthetic appearance deteriorates and construction costs increase
Solution Approach 1:
The ventilation function is extracted from the fixed frame and masonry and transferred to the movable sliding door leaf. The ventilation profile is integrated into the sliding door rather than being a separate attachment to the frame, allowing the ventilation opening to be covered when the door is closed and exposed when opened.
Solution Approach 2:
The ventilation profile is merged with the sliding door leaf as an integrated component. The ventilation openings are formed in the sliding door itself through the ventilation profile, combining the door's primary function with the ventilation function in a single unified structure.
2Quantity of substance
If an additional hollow profile is attached to the fixed frame for ventilation, then air exchange is enabled, but masonry modifications are required and construction costs increase
Solution Approach 1:
The ventilation function is extracted from the fixed frame structure and relocated to the sliding door leaf. This eliminates the need for modifications to the masonry or fixed frame, as the ventilation profile is self-contained within the movable door assembly.
Solution Approach 2:
The sliding door leaf is given multiple functions: it provides the primary door closure function and simultaneously houses the ventilation profile for air exchange. This multi-functionality eliminates the need for separate ventilation installations in the masonry or fixed frame.
3Quantity of substance
If the sliding door is opened a crack for ventilation, then air exchange is enabled, but security and accessibility are compromised
Solution Approach 1:
The sliding door leaf is segmented into functional zones: a solid door portion for security and accessibility, and a separate ventilation profile portion with openings for air exchange. This segmentation allows the door to provide ventilation without compromising security, as the main door body remains intact and lockable.
Solution Approach 2:
The ventilation profile is designed to be movable relative to the sliding door leaf, allowing it to be positioned in different configurations. The ventilation openings can be aligned with or covered by the door leaf depending on the door's position, dynamically controlling air exchange while maintaining security when closed.
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
Enables unobtrusive air exchange while maintaining the door's closed appearance and providing burglary protection, with the ventilation profile retracting silently into the frame when not in use, ensuring a seamless integration and reduced construction requirements.
Implementation Method 1
the ventilation profile and/or on the sliding door are also conceivable. The mechanical coupling of the ventilation profile to the sliding door is preferable, however, since this coupling also offers burglary protection.

AI summary
The ventilation device (10) has a telescopic adjusting element formed by a ventilation strip (20), whereby the sliding door (16) can be brought to a lockable ventilation position relative to the vertical frame arm (12) of the fixed frame (14) against which the door lies in its closed position. The door can be locked in the closed position.
