Mounting element for attaching a bath accessory to a wall
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing fastening arrangements for bathroom accessories are complex to produce, requiring metal mold casting and separate decoration components, which complicates manufacturing and increases costs.
Innovation Solution
A hollow body, such as a turned hollow cylinder, is designed with an internal recess that serves as an undercut for the wall bearing, allowing for simplified production and integration of decorative features, eliminating the need for a separate cover sleeve.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If metal mold casting is used to produce the hollow cylinder with inside collar, then the hollow cylinder can be manufactured with the undercut structure, but the production process becomes complex and requires separate decoration components
Solution Approach 1:
The patent combines the hollow cylinder body and the decorative cover sleeve into a single integrated component. The turned hollow cylinder is manufactured with an internal recess that directly forms the undercut structure, eliminating the need for a separate inside collar and decorative cover sleeve assembly. This merging of functions into one component simplifies the production process and reduces manufacturing complexity.
Solution Approach 2:
Instead of creating the undercut structure through metal mold casting with an inside collar (conventional approach), the patent inverts the approach by using turning machining to create the internal recess that forms the undercut. This inversion of the manufacturing method simplifies production by using a more straightforward machining process rather than complex casting and assembly.
2Shape
If a separate cover sleeve with decoration is used, then an attractive appearance can be achieved, but the number of components and assembly steps increases
Solution Approach 1:
The patent merges the decorative function and the structural function into a single turned hollow cylinder component. The external surface of the turned cylinder provides the attractive appearance, while the internal recess provides the structural undercut. This eliminates the need for a separate decorative cover sleeve and reduces the total number of components.
Solution Approach 2:
The turned hollow cylinder serves multiple functions simultaneously: it provides the structural body of the fixture, creates the undercut through its internal recess, and provides the decorative appearance through its external surface. This multi-functionality eliminates the need for separate specialized components for each function.

AI summary
The invention relates to a fastening arrangement for attaching a bathroom accessory (2) to a wall (3), wherein the fastening arrangement (1) comprises a wall bracket (4) and a hollow body (5), in particular a hollow cylinder, which can be clamped by means of the wall bracket (4) and which, in particular, is axially closed at one end and has a geometric central axis (6), radially surrounds the wall bracket (4) in the mounted state. It is proposed that the hollow body (5) has a hollow body wall (5b) circumferential around the geometric central axis (6), which is radially machined on the inside and outside and has an internal recess (7) into which, in the mounted state, at least one circumferential section (8) of the wall bracket (4) radially inserts.
