Rotatable Cover Rosette for Angular Compensation at Wall Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cover rosettes struggle to reliably and functionally cover building-side wall openings, especially in sanitary and electrical installations, due to manufacturing and assembly inaccuracies, leading to angular deviations that affect the alignment of cover bodies relative to the wall surface.
Innovation Solution
A cover rosette with an inner and outer rosette body, where the outer body can rotate by a predetermined angle relative to the inner body, allowing for angular compensation to align precisely with the desired position, using a fastening structure that secures the position without requiring rework on the wall or disassembly of installed components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a fixed cover rosette design is used, then the structure is simple and easy to manufacture, but manufacturing and assembly inaccuracies cause angular deviations that prevent precise alignment with the wall surface
Solution Approach 1:
The cover rosette incorporates a rotatable outer body that can rotate relative to the inner body about the longitudinal axis, transforming a static fixed structure into a dynamic adjustable one. This allows the outer body to be rotated to compensate for angular deviations caused by manufacturing and assembly inaccuracies, enabling precise alignment with the wall surface while maintaining a relatively simple overall structure.
2Manufacturing precision
If the cover rosette is made adjustable to compensate for angular deviations, then alignment precision is improved, but the structure becomes more complex
Solution Approach 1:
The cover rosette is divided into two separate bodies: an inner body that is fixed to the functional unit and an outer body that can rotate relative to the inner body. This segmentation allows the adjustable outer body to compensate for angular deviations without requiring the entire cover rosette to be complex, as only the outer body needs the rotational capability while the inner body remains simple and fixed.
3Ease of manufacture
If a simple fixed cover rosette is used, then the device is easy to manufacture and install, but it cannot compensate for assembly inaccuracies leading to poor alignment
Solution Approach 1:
The rotatable outer body provides a simple dynamic adjustment mechanism that allows installers to compensate for assembly inaccuracies during installation. The outer body can be easily rotated to the correct angular position and held in place, providing alignment accuracy without requiring complex adjustment mechanisms or additional installation steps.
4Manufacturing precision
If the cover rosette allows rotation to compensate for angular deviations, then alignment accuracy is improved, but the fastening structure becomes more complex
Solution Approach 1:
The fastening structure includes a retention element on the outer body that engages with a retention opening on the inner body, providing automatic retention when the outer body is rotated to the correct position. This self-retaining mechanism eliminates the need for complex locking devices or additional fastening steps, maintaining simplicity while enabling accurate alignment through rotation.
