Renovation Façade Adapter Profile for Reusing Existing Support Profiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing facade renovation methods are costly, complex, and inefficient, often requiring complete removal of infill panels and seals, which can lead to material disposal issues and difficulty in assessing facade condition.
Innovation Solution
A renovation facade system comprising a support profile with grooves and an adapter profile with a seal, allowing infill elements to be mounted effectively by covering existing grooves and seals, using a single seal with spaced-apart strips to conceal the adapter profile, enhancing thermal insulation and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If complete removal of infill panels and seals is performed, then new facade can be installed, but material disposal complexity and cost increase
Solution Approach 1:
The renovation system is segmented into modular components: adapter profiles that attach to existing support profiles, new seals that fit into grooves, and new infill panels. This segmentation allows selective replacement of only necessary components (seals and infill panels) while preserving the existing support structure, eliminating the need for complete material removal and disposal.
Solution Approach 2:
The invention recovers and reuses the existing support profiles (mullions and transoms) from the old facade. By designing adapter profiles that attach to these existing support structures, the system recovers valuable structural materials that would otherwise be discarded, reducing waste and disposal costs while enabling facade renovation.
2Ease of operation
If old seals are replaced, then new infill panels can be installed, but seal contour availability and assessment difficulty arise
Solution Approach 1:
The adapter profile serves multiple functions: it attaches to the existing support profile, provides a mounting structure for new seals, and creates a standardized interface for new infill panels. This universal adapter design eliminates dependency on the original seal contours, allowing the same adapter system to work with various seal types and facilitating easier facade condition assessment.
Solution Approach 2:
The adapter profile acts as an intermediary component between the existing support profile and the new sealing system. It mediates the connection by providing standardized attachment points and grooves, eliminating the need to directly interface with the old seal contours and simplifying both installation and inspection processes.
3Ease of manufacture
If adapter profile is made visible, then structural function is clear, but aesthetic appearance deteriorates
Solution Approach 1:
The seal functions as a flexible covering element that conceals the adapter profile while maintaining its structural function. The seal is designed to wrap around or cover the adapter profile, creating a smooth, continuous surface that hides the mechanical connection components from view while still providing the necessary attachment function for infill panels.
Solution Approach 2:
The adapter profile is nested within the visual field created by the seal and support profile arrangement. The adapter sits between the support profile and the visible facade surface, with the seal and infill panels creating outer layers that conceal the adapter's presence, similar to nested dolls where inner components are hidden by outer layers.

AI summary
A renovation facade (1, 1') comprises a support profile (2, 2') on which at least one groove (22) for holding a sealing profile is formed on an outer side, and on which a plate-shaped infill element (4) is held. An adapter profile (5) with at least one seal (6) is fixed to the support profile (2, 2'), the adapter profile (5) at least partially covering the at least one groove (22) on the support profile (2, 2'), and the infill element (4) is clamped to the adapter profile (5) by the seal (6). Only a single seal (6) is fixed to the adapter profile (5), which has two spaced-apart sealing strips (61) on which an edge of an infill element (4) rests. The adapter profile (5) has a narrower width than the support profile (2, 2') and is enclosed on opposite sides by the seal (6). Furthermore, the invention relates to a method for producing a renovation facade (1, 1').
