Wedge Mounting Device for Wall Ridge Covering Profiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for fixing covering profiles on wall ridges coated with insulation complexes result in thermal bridges and increased costs due to the need for multiple cutouts in the insulation, and can damage the insulation with narrow bearing surfaces.
Innovation Solution
A device comprising a shim with a bearing face on the insulation complex and through-hole, featuring two threaded orifices for mounting the cover profile, and a single screw for fixing the wedge to the wall ridge, which reduces the need for large cutouts and provides stability by forming a stable base on the insulation complex.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If intermediate pieces are fixed directly to the wall ridge by multiple screws, then the covering profile can be securely mounted, but multiple cutouts in the insulation complex create thermal bridges and increase assembly time and costs
Solution Approach 1:
The device divides the fixing function into two separate components: the wedge (support element) and the intermediate piece (fixing element). The wedge provides a large bearing surface on the insulation complex without requiring cutouts, while the intermediate piece is fixed to the wall ridge through a single cutout and screw, thereby securing the covering profile. This segmentation resolves the contradiction by separating the thermal insulation preservation function from the mechanical fixing function.
Solution Approach 2:
The wedge acts as an intermediary element between the insulation complex and the intermediate piece. It transfers the load from the intermediate piece to the wall ridge through the insulation complex without requiring multiple cutouts, thus maintaining thermal insulation while enabling secure mounting of the covering profile.
2Object-affected harmful factors
If a rail with narrow bearing surface is used to fix the cover profile, then the insulation complex can be minimally invaded, but the insulation may be damaged under screw stress during assembly
Solution Approach 1:
The device separates the load-bearing function (wedge with large bearing surface) from the fixing function (intermediate piece with screws). The wedge's large bearing surface distributes screw stresses over a wide area, preventing insulation damage, while the intermediate piece provides the necessary mechanical strength for securing the covering profile.
Solution Approach 2:
The wedge serves as a cushioning element placed between the intermediate piece and the insulation complex. It absorbs and distributes the concentrated stresses from the screws before they reach the insulation complex, thereby protecting the insulation from damage during assembly while maintaining structural integrity.
3Reliability
If multiple cutouts are made in the insulation complex for intermediate pieces, then the covering profile can be fixed securely, but assembly time and costs increase
Solution Approach 1:
The device segments the fixing system so that the wedge requires only a single cutout for screw passage, while the intermediate piece is pre-formed with mounting holes. This reduces the number of cutouts needed in the insulation complex from multiple (for each intermediate piece) to just one per wedge, significantly reducing assembly time and costs while maintaining fixing stability.

AI summary
The device (4) has a wedge (5) comprising a mounting unit formed of threaded holes for mounting a covering profile (2) on the wedge. The holes open on an upper face of the wedge. A single fixing screw (6) fixes the wedge on a ridge (F) of a wall (M). The wedge has projections (51, 52) projecting from a flat base (50) that define a support face. The projections define support areas in which the holes are formed. Height of one of the projections is greater than that of another projection so as to provide slope of the profile and/or a slide. Independent claims are also included for the following: (1) a covering system for a ridge of a wall coated with insulation complex (2) a method for mounting a covering system on a ridge of a wall coated with insulation complex.
