Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sealing devices for sliding doors face challenges in sealing the upper area due to space constraints, especially when sliding doors have running rails at the top, limiting their flexibility and requiring specialized fittings.
Innovation Solution
A sealing device with an adjustable contact element and force transmission element that allows the sealing strip to be positioned centrally or eccentrically, enabling it to be adapted to different structural conditions, including the width of the sliding door leaf, and minimizing space requirements by not protruding into the running rail.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sealing devices are installed in the upper area of sliding doors, then sealing performance is improved, but space constraints and device complexity increase
Solution Approach 1:
The activation unit is designed with movable components including a contact element that can move vertically and a force transmission element that rotates around an axis. This dynamic design allows the activation unit to adapt to the sliding door's movement and maintain effective sealing contact without requiring complex fixed mounting structures.
Solution Approach 2:
The activation unit is divided into separate functional components: a contact element for receiving activation force, a force transmission element for transferring the force, and an actuating element for triggering the seal. This segmentation allows each component to be optimized independently and simplifies the overall installation in space-constrained upper door areas.
2Adaptability or versatility
If the contact element is positioned centrally on the door leaf, then adaptability to different door widths is improved, but the distance adjustment mechanism increases device complexity
Solution Approach 1:
The distance between the contact element and actuating element is made adjustable through a dynamic mounting system. The force transmission element can be positioned at different locations along the activation unit's longitudinal axis, allowing adaptation to various door widths and sealing requirements without requiring completely different device configurations.
3Ease of operation
If the sealing device is designed to minimize space requirements, then ease of installation is improved, but the activation mechanism complexity increases
Solution Approach 1:
The activation unit utilizes vertical space efficiently by positioning the contact element to engage with the sliding door leaf during its closing movement. The force transmission element rotates around a horizontal axis, converting vertical movement into rotational motion that actuates the seal. This three-dimensional arrangement minimizes the horizontal space required while maintaining effective activation functionality.
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 effective sealing in the upper region of sliding doors independently of the door's suspension, reducing the need for specialized fittings and allowing for narrower door frames, particularly beneficial for glass doors, while maintaining airtight and soundproof performance.
Implementation Method 1
the contact element slides up a stationary inclined surface, thereby activating the drop-down mechanism
Implementation Method 2
Movement of the contact element acts, via the force transmission element, on an actuating element of the actuating mechanism

AI summary
A sealing device for a sliding door with a slidably mounted door leaf (F) comprises a seal (1), an activation unit (2), and a contact module (3). A sealing strip (11, 12) of the seal (1) can be moved into a sealing position by means of an actuating mechanism. The activation unit (2) has a contact element (23) for contacting the contact module (3) when the door leaf (F) closes and a force transmission element (24). The movement of the contact element (23) acts, via the force transmission element (24), on an actuating element (13) of the actuating mechanism and activates the actuating mechanism. The distance between the contact element (23) and the actuating element (13) is adjustable. The device according to the invention enables optimal sealing against air and light ingress as well as against sound. It can be installed in a space-saving manner and with ease.
