Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for attaching sheet cladding to walls are either labor-intensive, require visible fasteners, or fail to accommodate thermal expansion, leading to issues with alignment and warping.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If sheets are attached directly to the wall using nails or screws, then the attachment is simple and strong, but the fasteners remain visible and the surface irregularities on the wall are not eliminated
Solution Approach 1:
The invention extracts the fastening function from visible surface-mounted fasteners and relocates it to hidden connection elements embedded within the profile structure. The profiles contain internal connection elements that attach sheets invisibly, removing the visual disturbance while maintaining attachment strength.
Solution Approach 2:
The profile acts as an intermediary component between the wall and the sheet. It provides a standardized mounting surface that eliminates wall irregularities, incorporates hidden fastening mechanisms, and allows for insulation material placement, thereby solving multiple problems simultaneously without visible fasteners.
2Device complexity
If tongue and groove connection is used to attach panels invisibly, then no visible fasteners remain, but the sheet material needs extra machining and the connection can only accommodate thermal expansion to a limited extent
Solution Approach 1:
The invention replaces the mechanical tongue and groove interlocking system with a magnetic coupling system. Magnetic coupling parts are attached to the rear side of panels and connect to corresponding parts in the profiles, providing invisible attachment without requiring complex machining of the sheet material itself.
Solution Approach 2:
The magnetic coupling system changes the attachment mechanism from rigid mechanical interlocking to flexible magnetic attraction. This allows the panels to accommodate thermal expansion and contraction freely while maintaining invisible attachment, as the magnetic force can accommodate small positional variations without requiring precise machining tolerances.
3Device complexity
If sheets are glued to the profiles, then the attachment is strong and invisible, but the sheets warp under significant temperature differences and the process is labour-intensive with strict control requirements
Solution Approach 1:
The magnetic coupling system provides a dynamic attachment that allows for adjustment and repositioning during installation. The panels can be shifted in the plane of the panel to obtain good mutual alignment, and even after attachment, they can be removed and repositioned without damage, unlike rigid gluing which requires strict control and offers no post-installation adjustment.
Solution Approach 2:
The invention replaces the chemical bonding process of gluing with a magnetic field-based attachment system. This eliminates the need for labour-intensive gluing operations under strict controlled circumstances and allows for easy alignment adjustment. The magnetic coupling provides strong attachment while maintaining flexibility for installation adjustments.
4Device complexity
If frames are attached adjacently without touching each other, then connecting elements can be slid in to connect frames invisibly, but the mounting process becomes more complex
Solution Approach 1:
The profiles are pre-provided with grooves that guide the connecting elements into position. This preliminary preparation of the groove structure allows connecting elements to be easily slid into place without complex alignment procedures, maintaining mounting speed while achieving invisible connections between frames.
Solution Approach 2:
The connecting elements act as intermediaries that bridge the gap between adjacent frames. They are guided into position by grooves in the profiles and provide invisible mechanical connection, allowing frames to be connected without direct contact while maintaining installation efficiency through the groove guidance system.

AI summary
Wall cladding comprising several frames (2) and several panels (7), whereby each frame is composed of profiles and whereby against the front side of each frame at least one of the panels (7) is applied. The wall cladding further comprises connecting elements (6), applied for connecting adjacent frames (2) in grooves (9) formed all around in the outer edge of the frames. Each panel (7) is attached to the corresponding frame (2) by means of at least one or more first coupling parts (8) that are attached to the panel and by one or more cooperating second coupling parts (4) that are attached to the profiles, whereby the first coupling parts and the second coupling parts are provided to attract or reject each other magnetically, in such a way that they allow a mutual shift of the panel relative to the frame, in a direction parallel to the plane of the panel.
