Embedded Rail Profile for Screw-Free Wall Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional profile systems for fastening objects to walls require drilling screws through plate-covered surfaces, damaging surface seals and limiting load-bearing capacity due to localized force distribution.
Innovation Solution
A profile system with a rail profile having a rectangular base section and fastening legs embedded in tile adhesive, and a plug element with a swiveling head section that locks into a receiving groove, allowing secure attachment without screws and distributing forces evenly across the wall.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If screws are used to fasten the rail profile to the wall, then the installation is simple and direct, but the surface seal is damaged and the aesthetic appearance is compromised
Solution Approach 1:
The rail profile is embedded into the plate covering during the tiling process itself, before the surface seal is applied. The fastening legs are positioned and secured in the tile adhesive bed, allowing the tiles and seal to be installed over them without subsequent drilling or damage to the seal.
Solution Approach 2:
The tile adhesive acts as an intermediary medium that bonds the fastening legs to the wall structure. Instead of directly fastening through the finished surface, the adhesive provides a bonding interface that secures the rail profile while allowing the plate covering and seal to remain intact.
2Device complexity
If conventional plug elements are used that only support themselves locally on the rail profile, then the assembly is simple, but the load-bearing capacity is limited due to localized force introduction
Solution Approach 1:
The load-bearing element extends the support from a single point contact to a distributed area contact. By spreading the load across multiple attachment points along the rail profile and distributing forces to multiple wall anchor points, the system transitions from localized to distributed load bearing.
Solution Approach 2:
The load-bearing element changes the mechanical parameters of the connection by increasing the contact area and distributing forces across multiple points. This transforms the load introduction from concentrated local stresses to distributed stresses, significantly increasing the overall load-bearing capacity of the system.

AI summary
A profile system (1) for fastening objects to a room wall provided with a plate covering comprises at least one elongated rail profile (2), which extends in a longitudinal direction (L) and has a constant cross-section, and at least one plug element (3), which is designed to be fastened directly and detachably to the rail profile (2) in a plug-in manner. The rail profile (2), viewed in cross-section, has a substantially rectangular base section (6), whose depth (T) is adapted to the thickness of the plate covering and which is provided on its front side with a receiving groove (7) extending in the longitudinal direction (L) with a groove opening (9) accessible from the outside, and at least one fastening leg (13) which adjoins the rear side of the base section (6) substantially flush and projects outwards from the base section (6).
