Rosette Device Asymmetric Sleeve Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rosette devices for sanitary fittings have a rotationally symmetrical sleeve design that limits the cross-sectional shape of the sleeve visible in the installed state, which cannot be customized to match the aesthetic design of the fittings.
Innovation Solution
A rosette device with a sleeve composed of multiple parts, including a spindle body and rosette socket, where the spindle body is axially adjustable via a threaded arrangement without rotating the rosette socket, allowing for any desired cross-sectional shape of the sleeve visible in the installed state by using a depression in the rosette to accommodate the socket and enabling independent axial movement without relative rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the sleeve is designed as a single rotationally symmetrical part, then it can be easily manufactured and assembled, but the cross-sectional shape is limited and cannot be customized for aesthetic design
Solution Approach 1:
The sleeve is divided into two separate parts: a rosette socket and a spindle body. The rosette socket remains rotationally symmetrical for easy manufacture, while the spindle body can have any desired cross-sectional shape. These parts are connected through a threaded arrangement that allows relative rotation, enabling the spindle body to be positioned axially without requiring the rosette socket to rotate.
2Adaptability or versatility
If the sleeve is designed with any desired cross-sectional shape, then aesthetic adaptation is improved, but the manufacturing complexity increases
Solution Approach 1:
The complex shape requirements are isolated to the spindle body only, while the rosette socket maintains a simple rotationally symmetrical design. This segmentation allows the complex cross-sectional shape to be achieved without making the entire sleeve device complex, as only one component needs the custom shape.
Solution Approach 2:
The spindle body is designed with an asymmetric cross-sectional shape that can be customized to match aesthetic requirements, while the rosette socket remains symmetric. This allows the visible portion of the sleeve to have the desired custom shape without requiring the entire assembly to be asymmetric, thereby controlling overall device complexity.
3Ease of operation
If the rosette socket and spindle body rotate relative to each other during axial adjustment, then the threaded arrangement functions, but the rosette socket must be rotationally symmetrical
Solution Approach 1:
The rotational and axial adjustment functions are separated between two components. The spindle body rotates relative to the rosette socket during axial adjustment, while the rosette socket itself does not rotate. This segmentation allows the spindle body to achieve any cross-sectional shape while maintaining the threaded adjustment functionality.

AI summary
The invention relates to a rosette device (1) for covering a wall connection (2) for a sanitary fitting body (3), comprising a rosette (4) that can be brought into contact with a wall and a sleeve assembly that is axially adjustable in the rosette by means of a thread (5). In the assembled state, the sleeve assembly can be axially slid onto a union nut (6) of the wall connection (2). According to the invention, the sleeve assembly is designed in multiple parts with a rosette socket (7) and a spindle body (8), wherein the spindle body (8) is axially adjustable in the rosette (4) by means of the thread (5) by a relative rotation with respect to the rosette and is rotatably coupled to the rosette socket (7).The rosette fitting extends into a recess (9) formed in the rosette (4) and in particular surrounding the thread (5), so that the rosette fitting (7) is moved axially into or out of the recess (9) during the axial adjustment of the spindle body (8) caused by relative rotation of the spindle body (8) and the rosette (4), without rotating.
