Automatic Door Clamping for Seamless Facade Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic door systems are difficult to install and visually stand out from other building elements, creating a complex and aesthetically disturbing integration with the building facade.
Innovation Solution
An automatic door system featuring a movable door leaf with a drive device and a fixed door leaf that uses clamping devices to attach to the building's supporting structures without screws, allowing for seamless integration and simplified installation by matching the building's design and panel arrangement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional profile systems with screw connections are used to install automatic door systems, then the door system can be securely attached to the building structure, but the installation becomes complex and the door system visually stands out from other façade elements
Solution Approach 1:
The patent extracts the visible profile system and screw connections from the final installation, using them only during the installation process. The fixed door leaf is designed with integrated attachment means that allow temporary profiling during installation, which is then removed or concealed, leaving a clean facade without visible mounting hardware.
Solution Approach 2:
The patent applies preliminary action by pre-assembling the door leaf with its attachment components in a controlled environment before installation. The profile system and connection elements are prepared in advance, allowing for simplified on-site installation that doesn't require complex facade work or visible structural modifications.
2Reliability
If traditional profile systems with screw connections are used to install automatic door systems, then the door system can be securely attached to the building structure, but the installation time increases and the process becomes more difficult
Solution Approach 1:
The patent segments the installation process into distinct phases: pre-assembly of the door leaf with attachment components, positioning on the facade, and final securing. This segmentation allows each phase to be optimized independently, reducing overall installation time while maintaining secure attachment through the multi-stage process.
3Reliability
If traditional installation methods are used, then the door system can be attached to the building, but it creates abrupt transitions from glass surfaces and does not integrate well with the building design
Solution Approach 1:
The patent applies local quality by designing the fixed door leaf with surface characteristics and edge profiles that match the surrounding glass panels and facade elements. The attachment points are localized to minimize visual impact, and the door leaf's geometry is tailored to blend seamlessly with the specific building's aesthetic requirements.
4Reliability
If complex profile systems are used for installation, then the door system can be attached to the building structure, but the door system becomes visually disturbing and stands out from other façade elements
Solution Approach 1:
The patent uses an intermediary approach by introducing a fixed door leaf that acts as a mediator between the building structure and the movable door system. This fixed leaf provides the necessary structural attachment points while presenting a clean, design-integrated surface to the facade, hiding the attachment mechanisms from view.

AI summary
An automatic door system (1) in the form of a sliding door, a telescopic sliding door, or a folding door comprises a first movable door leaf (2a) and a first fixed door leaf (5a). The automatic door system (1) includes a first and/or a second clamping device (30a, 30b). The first clamping device (30a) is configured to press the upper edge (6c) of the first fixed door leaf (5a) directly or indirectly against a first supporting structure (25a) of the building and to clamp it to this structure and optionally to a first panel (60) of the building. The second clamping device (30b) is configured to press the first vertical edge (6e) of the first fixed door leaf (5a) against a second supporting structure (25b) of the building and to clamp it to this structure and optionally to a second panel (60) of the building.In this case, a front face (6a) of the first fixed door leaf (5a) runs in the same plane as a front face (60a, 61a) of the first and/or second panel (60, 61) of the building.
