Extruded Ceramic Facade Panel Rebate Reinforcement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Facade panels for ventilated curtain-type facade structures are prone to breakage due to vandalism, as their head and foot rebates are not dimensioned to withstand impact stresses, leading to security vulnerabilities.
Innovation Solution
The solution involves reinforcing the head and foot rebates of the facade panels by increasing their thickness, with the rear panel wall having a smaller thickness and reinforcement in the form of elevations or depressions near core holes, allowing for cut-to-length panels that can be securely placed in panel holders with enhanced rebate break-off resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the head and foot rebates are made thicker to withstand impact stresses, then the strength and vandalism resistance of the facade panel is improved, but the material consumption and production complexity increase
Solution Approach 1:
The patent applies local quality by making only the head and foot rebates thicker while keeping the main panel wall thickness uniform. This localized thickening provides the necessary strength and vandalism resistance at critical areas without increasing material consumption throughout the entire panel, thus resolving the contradiction between strength improvement and material efficiency.
Solution Approach 2:
The patent segments the panel into different thickness zones: the main panel wall maintains a standard uniform thickness, while only the head and foot rebates are thickened. This segmentation allows the structure to have both lightness (low material consumption) and strength (high rebate resistance) in different areas simultaneously.
2Ease of manufacture
If the wall thicknesses are made substantially uniform to ensure uniform material flow during extrusion, then the manufacturing ease is improved, but the strength of the rebates against vandalism deteriorates
Solution Approach 1:
The patent resolves this contradiction by applying local quality - the main panel wall maintains uniform thickness for easy manufacturing and uniform material flow, while the head and foot rebates are locally thickened to provide the necessary strength. This allows both uniform material flow during extrusion and high impact resistance to be achieved simultaneously.
3Loss of substance
If the rear panel wall is made thinner to reduce material consumption, then the material efficiency is improved, but the overall strength of the panel deteriorates
Solution Approach 1:
The patent applies local quality by making the rear panel wall thinner in non-critical areas to improve material efficiency, while simultaneously thickening the head and foot rebates locally to maintain overall panel strength. This allows material efficiency and strength to coexist by placing material only where structurally necessary.

AI summary
What is described is an extruded ceramic facade panel (20) for a ventilated curtain-type facade structure, comprising at least one preferably rear head rebate (25) and one preferably rear foot rebate (26) and also at least one core running in the direction of extrusion, in which panel the wall between the core hole (24) and the rear of the facade panel has at least one elevation (22e) and the thickness of the wall between the highest point of the elevation (22e) and the rear of the facade panel is identical to the thickness of the head rebate (25) and/or to the thickness of the foot rebate (26). A method of producing such a facade panel is also described.
