Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing fastening systems are used to attach facade panels to C-profile rails, then the panels can be secured, but special profiles are required and the fastening process is cumbersome
Solution Approach 1:
The fastener is designed with a universal T-profile hammerhead element that can be attached to standard C-profile rails without requiring special profiles. The hammerhead element can be positioned transversely or at an angle within the rail, engaging the rail on both sides of the longitudinal slot to provide secure attachment while maintaining compatibility with conventional rail designs
Solution Approach 2:
The fastening system is divided into distinct functional components: the anchor for securing to the panel back side, the fastener body with U-shaped bracket, and the hammerhead element for attachment to the rail. This segmentation allows each component to be optimized for its specific function while simplifying the overall installation process
2Ease of operation
If conventional fastening methods are used, then attachment is possible, but the process is cumbersome and difficult to handle
Solution Approach 1:
The anchor is pre-installed in the back side of the facade panel before the fastening process begins. This preliminary action eliminates the need to drill and install anchors during the fastening operation, significantly reducing installation time and simplifying the handling of the fastening system
Solution Approach 2:
The fastener incorporates a rotatable ring fitting that allows the U-shaped bracket to rotate about an axis perpendicular to the web. This dynamic feature enables easy adjustment and alignment of the fastener during installation, making the system more flexible and easier to handle in various mounting positions
3Reliability
If the hammerhead element is positioned transversely in the C-profile rail, then positive locking is achieved preventing perpendicular movement, but insertion complexity increases
Solution Approach 1:
The hammerhead element features an asymmetric T-profile design with a head and a body. This asymmetric shape allows the element to be inserted through the longitudinal slot of the C-profile rail and then positioned transversely within the rail. The asymmetric geometry provides inherent directional guidance, ensuring proper orientation and engagement with the rail walls to achieve positive locking while simplifying the insertion process
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
The system allows for easy and secure fastening of facade panels to C-profile rails without special profiles, ensuring stability and preventing perpendicular movement through positive locking mechanisms.
Implementation Method 1
the anchor is an undercut anchor which is spread out in the blind hole having an undercut, which is installed in the back of the facade panel and is thereby anchored in the facade panel
Implementation Method 2
If the hammerhead is positioned transversely or at an angle within the C-profile rail, it engages the rail on both sides of the longitudinal slot. This positive locking action prevents it from being pulled out of the C-profile rail perpendicular to the side of the C-profile rail containing the longitudinal slot
Implementation Method 3
The anchor is preferably rotatably attached to the web of the first fastener by means of a ring fitting about an axis perpendicular to the web

AI summary
In order to secure a cladding panel (21) to a C-profile rail (24), the invention proposes a first and second fastener (1, 14), each of which has a sheet metal strip that is bent into a U-shaped bracket (8). The second fastener (14) has a hammer head (15) on a flange bracket (18) and is rotatably secured in an anchoring hole on the rear face (22) of the cladding panel (21) by means of an undercut anchor (13). By moving the cladding panel (21) transversely to the C-profile rail (24), the hammer head (15) is brought into engagement behind the C-profile rail (24), thereby securing the cladding panel (21) to the C-profile rail (24).
