Rectangular Wall Rosette Assembly With Anti-Twist Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Angular wall rosettes for sanitary fittings face challenges in precise alignment during installation and maintaining that alignment, as existing solutions do not ensure horizontal and vertical edges are accurately aligned and secured, leading to potential twisting during use.
Innovation Solution
A fastening element with an internal thread is inserted between the S-bend and the wall rosette, featuring a clamping mechanism, such as an O-ring, to secure the rosette against rotation, and a pressure washer for sealing, ensuring axial bracing and preventing unintentional twisting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a square wall rosette is mounted using conventional methods, then the installation process is simple, but the alignment precision and anti-twist security are insufficient
Solution Approach 1:
A fastening element is introduced as an intermediary component between the wall rosette and the S-bend. This fastening element includes a threaded connection for securing to the S-bend and a clamping mechanism with an O-ring for securing the wall rosette, thereby achieving precise alignment and anti-twist security without complicating the overall installation process
Solution Approach 2:
The fastening system is divided into separate functional components: a fastening element for threaded attachment to the S-bend, a clamping mechanism with O-ring for securing the wall rosette, and the wall rosette itself. This segmentation allows each component to perform its specific function effectively while maintaining overall system simplicity
2Ease of operation
If the wall rosette is secured without additional fastening means, then the installation is easier, but the rotational security and alignment maintenance are compromised
Solution Approach 1:
An O-ring made of elastomer is used as the clamping means. The O-ring's flexible nature allows it to be compressed axially during installation and then maintain continuous frictional clamping force on the wall rosette, providing reliable rotational security while enabling easy manual installation without additional fastening means
Solution Approach 2:
The O-ring clamping mechanism provides a cost-effective solution that achieves reliable rotational security through frictional clamping. The simple elastomeric design is inexpensive to manufacture and install, yet provides sufficient reliability to prevent unintentional twisting during use
3Stability of the object's composition
If the thread size is reduced to achieve anti-twist security, then the rotational stability improves, but the clamping force and overall strength are reduced
Solution Approach 1:
The fastening element combines multiple functions: a threaded connection for axial securing to the S-bend and an O-ring clamping mechanism for radial securing of the wall rosette. This merging of functions allows the system to achieve both rotational stability and sufficient clamping force without relying solely on thread size
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution allows for precise alignment and secure fixation of the wall rosette, preventing accidental twisting during installation and use, while maintaining the set angular position with enhanced frictional clamping, ensuring the rosette remains aligned and sealed.
Implementation Method 1
The compression creates a frictional clamping and the angle position once set is retained during use of the sanitary fitting
Implementation Method 2
The shoulder provided for the connection has an internal thread, via which it can be screwed onto the threaded shoulder of the S-bend
Implementation Method 3
a sealing ring is attached to seal it against the wall surface
