Rotatable Cover Rosette for Sanitary Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sanitary installation sets face challenges in reliable and efficient installation due to manufacturing and assembly inaccuracies, leading to deviations in the position of functional blocks and cover rosettes, resulting in visual and functional issues such as gaps, leaks, and misaligned control elements.
Innovation Solution
The sanitary installation set features a cover rosette with an inner and outer rosette body, where the inner rosette body is fixed at a variable axial height to the functional block base body and the outer rosette body is rotatable by a predetermined angular compensation amount, allowing for easy adjustment to compensate for height and angular inaccuracies without requiring rework on the wall or existing components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional fixed-position installation is used, then manufacturing precision is improved, but assembly ease deteriorates due to inability to compensate for deviations
Solution Approach 1:
The cover rosette is designed with rotational mobility around the longitudinal axis of the functional block, allowing it to dynamically adjust its angular position to compensate for assembly deviations. The outer rosette body can rotate relative to the inner rosette body by a predetermined angle compensation amount, transforming a static fixed-position installation into a dynamic adjustable one, thereby resolving the contradiction between manufacturing precision and assembly ease.
2Manufacturing precision
If rework is performed to compensate for assembly inaccuracies, then position accuracy is improved, but productivity deteriorates due to additional work requirements
Solution Approach 1:
The cover rosette is pre-designed with built-in angle compensation capability and rotational mobility, allowing installers to simply rotate the outer rosette body to the correct position without requiring any rework on the wall opening, box, function block, or rosette itself. This preliminary design feature eliminates the need for time-consuming corrective operations, thereby maintaining position accuracy while preserving installation efficiency.
3Reliability
If complex rework is performed on wall opening and components, then reliability is improved, but device complexity increases
Solution Approach 1:
The cover rosette incorporates rotational mobility around the longitudinal axis of the functional block, with the outer rosette body capable of rotating by a predetermined angle compensation amount relative to the inner rosette body. This dynamic adjustment mechanism allows the cover rosette to automatically compensate for assembly and manufacturing inaccuracies, achieving reliable installation without requiring complex rework procedures, thereby improving reliability while minimizing installation complexity.
