Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing façade cladding fastening systems face challenges in adjusting for incorrect positioning and accommodating irregular building surfaces, requiring costly surface leveling and limiting flexibility in achieving a straight and even façade installation.
Innovation Solution
A façade cladding fastening system with adjustable C-rail profiles and rotatable adjusting members that allow three-dimensional adjustment, enabling flexible installation without the need for surface leveling, using materials like metal or plastic for the profiles and adjusting members, and incorporating locking mechanisms for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a bracket and profile system is fixed to the wall for mounting façade cladding, then the cladding can be securely fastened, but the position cannot be corrected if mounted at wrong position and the building wall surface irregularity cannot be accommodated
Solution Approach 1:
The fastening system incorporates adjustable members with threading mechanisms that allow dynamic repositioning of profiles along the wall surface. The threaded adjustment enables the profiles to be moved to different positions and locked at desired locations, transforming a static fixed system into a dynamic adjustable one.
Solution Approach 2:
The fastening system is divided into separate modular components: brackets fixed to the wall, adjustable members with threading, and profiles that can be independently positioned. This segmentation allows each component to perform its specific function and enables easy adjustment without moving the entire system.
2Manufacturing precision
If the outer surface of the building wall is leveled and smoothened to accommodate cladding, then the façade can form a straight and even surface, but the process is time and money consuming
Solution Approach 1:
Instead of trying to make the wall surface perfectly flat in two dimensions, the invention introduces a third dimension by positioning profiles at different distances from the wall surface using adjustable members. This allows the façade to achieve straightness and evenness by compensating for wall irregularities through depth adjustment rather than surface preparation.
Solution Approach 2:
The adjustable members act as intermediaries between the irregular wall surface and the profiles. They absorb and compensate for the surface irregularities, allowing the profiles to be positioned at uniform distances from each other and from the wall, thereby achieving a straight and even façade without modifying the wall surface.
3Strength
If fixing members are mounted on concrete structure for each cladding, then secure fastening is achieved, but it is difficult to adjust cladding positions
Solution Approach 1:
The system uses adjustable members with threading that allow the profiles to be dynamically repositioned along the wall. The threaded mechanism provides both secure attachment (when locked) and adjustability (when unlocked), enabling the system to transition between fixed and adjustable states as needed.
Solution Approach 2:
The adjustable members serve multiple functions: they provide secure fastening to the wall, enable position adjustment during installation, allow correction of positioning errors, and accommodate wall surface irregularities. This multi-functionality replaces the need for separate fixing and adjusting mechanisms.

AI summary
A façade cladding (18) fastening system (1) comprising at least two first profiles (2) arranged to be fastened to the wall of a building, at least two second profiles (3) fastened to the first profiles, wherein the second profile is fastened to the first profile with an adjusting member (4), wherein the adjusting member, having a central axis (5) perpendicular to the first and second profiles, is configured to slide along the first profile and/or the second profile for adjusting the position of the second profile in relation to the first profile, and move along its central axis (5) for adjusting the distance between the first and the second profile.
