External Pin-Guided Façade Panels for Tolerance Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing facade panel arrangements face limitations in accommodating positional tolerances and pin diameters, especially with thin panels, as the pin and guide are constrained by the panel thickness, limiting adjustability and stability.
Innovation Solution
The pin and guide are positioned completely outside the facade panels, allowing for larger diameter pins and greater tolerance compensation, with anchoring devices fixed to the panels via casting, enabling adjustable and secure positioning without visible fasteners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the pin and guide are arranged within the facade panels, then the installation is simpler, but the tolerance compensation and pin diameter are limited by the panel thickness
Solution Approach 1:
The pin and guide are moved from the traditional in-panel arrangement to an external arrangement in the space between the facade panel and the supporting structure. This dimensional relocation eliminates the constraint of panel thickness, allowing for larger pin diameters and greater tolerance compensation capabilities while maintaining installation simplicity through the anchoring device
2Reliability
If the pin diameter is increased for better stability, then the connection is more stable, but the panel thickness requirement increases
Solution Approach 1:
By relocating the pin-guide arrangement to the external space between the facade panel and supporting structure, the system decouples the pin diameter from the panel thickness constraint. This allows using pins with larger diameters for enhanced stability without increasing the required panel thickness, as the pin no longer needs to pass through the panel material
3Adaptability or versatility
If the pin and guide are arranged outside the facade panels, then the tolerance compensation and pin diameter are not limited, but the anchoring complexity increases
Solution Approach 1:
The anchoring device combines multiple functions into a single integrated component: it anchors both the pin and the guide to the facade panel, provides positioning functionality, and ensures stable connection. This merging of functions simplifies the overall structure and reduces the number of separate components needed, thereby reducing anchoring complexity while maintaining high adaptability for tolerance compensation
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
This solution provides secure and adjustable facade panel arrangements that can accommodate larger pin diameters and tolerate positional discrepancies, ensuring stable and aesthetically pleasing installations, particularly suitable for thin panels.
Implementation Method 1
The pin and guide are each secured to the corresponding facade panel by an anchoring device. A simpler design is achieved when the anchoring devices are at least partially cast into the corresponding facade panel.

AI summary
A facade panel arrangement (1) comprises a first facade panel (2) and a second facade panel (3) which are arranged one above the other. A pinning system (4) comprising a pin (5) and a guide (6, 6') is provided for pinning the facade panels (2, 3). The pin (5) is held on the first facade panel (2, 3) and the guide (6, 6') is arranged on the second facade panel (3, 2). The pin (5) protrudes into the guide (6, 6'). The pin (5) and the guide (6, 6') are arranged completely outside the facade panels (2, 3) and are each fixed to the associated facade panel (2, 3) via an anchoring device (7, 8).
