Sanitary Water Outlet Fitting with Detachable Cover for Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sanitary water outlet fittings lack effective accessibility and maintenance for components housed within the fitting body, with existing solutions not fully addressing the need for easy access and periodic maintenance.
Innovation Solution
A sanitary water outlet fitting design featuring a completely coverable maintenance opening with a detachable cover, incorporating a carrier plate and seal for water-tight sealing, allowing for easy access to valve units and insert elements, and utilizing a snap connection and thermoplastic multi-component parts for secure attachment and manufacturing advantages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the outlet section is designed with an open top for accessibility to internal components, then maintenance access is improved, but water sealing and aesthetic appearance deteriorate
Solution Approach 1:
The cover is segmented into a support plate and a cover plate that can be detachably attached. The support plate integrates with the seal to provide water-tight sealing, while the cover plate provides aesthetic appearance. This segmentation allows the cover to simultaneously achieve sealing functionality and aesthetic appearance.
Solution Approach 2:
The support plate acts as an intermediary element between the outlet section and the cover plate. It provides a mounting surface for the cover plate while integrating the seal to ensure water-tight sealing, thus mediating between the conflicting requirements of accessibility, sealing, and appearance.
2Ease of repair
If the cover is made detachable for easy maintenance access, then ease of repair is improved, but water sealing reliability deteriorates
Solution Approach 1:
The seal is merged with the support plate to form an integrated assembly. The seal protrudes into the outlet section and can be attached directly to it, ensuring that water sealing is maintained even when the cover is detachably attached for maintenance access.
3Shape
If the cover completely covers the open top for aesthetic appearance, then appearance quality is improved, but accessibility to internal components deteriorates
Solution Approach 1:
The cover is designed to be dynamically attachable and detachable rather than fixed. The detachable connection structure allows the cover to be removed for maintenance access and reattached for aesthetic appearance, providing dynamic adaptability between conflicting functional requirements.
4Ease of manufacture
If separate components are used for cover and seal for manufacturing flexibility, then ease of manufacture is improved, but device complexity increases
Solution Approach 1:
The seal and support plate are merged into a single integrated component with the seal protruding into the outlet section. This merging reduces the number of separate parts and assembly steps, simplifying the overall device complexity while maintaining manufacturing flexibility through the detachable connection structure.

AI summary
1. Sanitary water outlet fitting. 2.2. The invention relates to a sanitary water outlet fitting with a fitting body (1) which is divided into an inlet section (2) and an adjoining outlet section (3) with an open top, and a cover (17) detachably attached to the fitting body on the open top of the outlet section. 2.2. In the water outlet fitting according to the invention, the open top of the outlet section serves as a maintenance opening (4), with the cover closing the open top of the outlet section. A valve unit (5) and/or insert element (6) with a particle screen and/or a flow regulator is accommodated in the fitting body and is accessible via the maintenance opening.The cover comprises a support plate (18) attached to the outlet section by a detachable connecting structure (22), a seal (19) circumferentially around the underside of the support plate, and a cover plate (20) attached to the top of the support plate. 2.3. Use e.g. as a water outlet fitting on a washbasin or bathtub.
