Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ventilated facade devices require numerous continuous components for installation, leading to high costs, complexity, and reduced watertightness, with limited panel size due to wind load constraints, necessitating smaller panels and more joints, which increases material usage and installation time.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If numerous continuous components are used for installation, then the structural stability is improved, but the device complexity and material usage increase
Solution Approach 1:
The patent divides the facade system into discrete panel units, each with integrated clamping features, rather than using continuous components. Each panel is an independent module that can be installed separately, reducing overall system complexity while maintaining structural stability through the modular arrangement of these segmented units.
Solution Approach 2:
The clamping features are merged directly into the panel structure itself, eliminating the need for separate continuous support components. The panels incorporate integrated upper and lower clamping features that are part of the panel body, reducing the total number of components and simplifying the overall device structure.
2Stability of the object's composition
If numerous continuous components are used for installation, then the structural stability is improved, but the material usage and cost increase
Solution Approach 1:
By segmenting the facade into discrete panels with integrated clamping features, the system reduces material usage compared to continuous components. The modular design allows for optimized material consumption in each panel while maintaining overall structural stability, eliminating the need for excessive continuous support structures.
Solution Approach 2:
The panels serve multiple functions simultaneously: they provide the facade surface, incorporate the clamping features for attachment, and include the flanges for overlapping and water management. This multi-functionality eliminates the need for separate continuous components, reducing total material usage while maintaining structural stability.
3Stability of the object's composition
If continuous components are installed on the facade, then the installation stability is improved, but the installation time and complexity increase
Solution Approach 1:
The clamping features are pre-installed on the panels during manufacturing, eliminating the need for on-site installation of these components. The panels arrive at the construction site ready with their clamping features attached, significantly reducing installation time and complexity while maintaining installation stability.
Solution Approach 2:
The segmentation into discrete panels with pre-installed features allows for faster, more flexible installation compared to continuous components. Each panel can be independently handled and attached to the facade, reducing the time required for installation while maintaining stability through the modular connection system.
4Strength
If smaller panels are used, then the wind load resistance is improved, but the number of joints and material usage increase
Solution Approach 1:
The system uses segmented panels of optimized sizes that balance wind load resistance with material efficiency. Each panel is designed to be sufficiently large to minimize the number of joints while remaining small enough to effectively resist wind loads, creating an optimal balance between these competing requirements.
Solution Approach 2:
The panels utilize composite construction with stiffening profiles and integrated clamping features that enhance wind load resistance. The composite structure allows for larger panel dimensions that can better resist wind forces while reducing the total number of joints needed, thereby reducing material usage compared to traditional approaches.
5Object-affected harmful factors
If additional components are used for watertightness, then the protection against water entry is improved, but the device complexity and installation difficulty increase
Solution Approach 1:
The water management function is merged into the panel structure itself through integrated overlapping flanges and channels, eliminating the need for separate watertightness components. The flanges that overlap between adjacent panels create built-in water channels that direct water away from the insulation layer, providing protection while maintaining simplicity.
Solution Approach 2:
The overlapping flange system is self-regulating and automatically directs water away from the insulation without requiring additional active components or complex installation procedures. The geometry of the overlapping flanges inherently creates water channels that function autonomously to protect against water entry.

AI summary
The present invention relates to a clamping device for ventilated facades comprising a plurality of panels (3) and at least two upper clamping features (9) for each panel (3), wherein the upper clamping features (9) comprise an upper main body (11) and a first flange (12) extending from the upper main body (11), wherein the first flange (12) is linkable to a lower edge (6) of a panel (3) of another adjacent row and is intended to be attached to the upright profile (1). The level of insulation of the facade against the entry of water from the outside into the insulation layer behind the panels is thus improved by allowing the use of panels that overlap their adjacent panels by means of double-fold flanges and that describe geometries that create areas for water collection and channeling.
