Two-Part Mounting Nut for Fast Sanitary Fitting Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nuts for securing sanitary fittings to worktops require additional stabilizing components, precise production, and are laborious and time-consuming to install, especially on thin worktops, leading to high production costs.
Innovation Solution
A nut system comprising two freely rotatable nut parts that transition from an open to a closed position, allowing easy assembly by sliding and rotating onto an external thread, with features like a securing device, guide slots, and a return mechanism for quick release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a traditional nut design is used to secure sanitary fittings to worktops, then the fitting can be secured, but the installation becomes laborious and time-consuming especially on thin worktops
Solution Approach 1:
The nut is divided into a first nut part with threaded tabs and a second nut part that acts as a pressing element. This segmentation allows the threaded tabs to project radially outward for easy engagement with the external thread during installation, then be pressed radially inward by the second nut part to secure the fitting, significantly reducing installation effort and time.
Solution Approach 2:
The threaded tabs are designed to be dynamically adjustable between two states: projecting radially outward for easy engagement and pressed radially inward for secure fastening. This dynamic transformation enables the nut to adapt to different installation scenarios, particularly thin worktops, making installation quick and effortless.
2Ease of manufacture
If the threaded tabs are designed to project radially outward for easy engagement, then assembly is simplified, but additional stabilizing components are required
Solution Approach 1:
The first and second nut parts are merged into a single integrated nut assembly. The second nut part serves dual functions: pressing the threaded tabs radially inward for secure fastening and providing structural stability. This merging eliminates the need for separate stabilizing components while maintaining assembly simplicity.
Solution Approach 2:
The second nut part is designed as a multi-functional component that combines the pressing function with a stabilizing function. This universal design allows the nut to maintain simplicity during assembly while providing inherent stability, reducing the total component count.
3Reliability
If high precision is required during production to position threaded tabs correctly, then fastening reliability is improved, but production costs increase
Solution Approach 1:
The threaded tabs are pre-configured in the first nut part to project radially outward in their initial state. This preliminary positioning ensures correct alignment for engagement with the external thread before the pressing action occurs, eliminating the need for high-precision positioning during assembly and reducing production costs while maintaining fastening reliability.
Solution Approach 2:
The nut design allows the threaded tabs to self-align and self-position correctly through their radial projection geometry. The tabs naturally engage with the external thread at the correct position without requiring precision manufacturing tolerances, enabling cost-effective production while ensuring reliable fastening.

AI summary
The invention relates to a nut for securing a component to a support, in particular a sanitary fitting to a worktop, comprising a first nut part, and a second nut part, wherein the first nut part has at least two threaded tabs with threads on their radially inner side, and the two nut parts are arranged to be displaceable relative to one another along an axial axis, such that in a first position—open position—the threaded tabs of the first nut part can be arranged to protrude radially outward, and in a second position—closed position—the threaded tabs of the first nut part can be arranged by means of the second nut part, in particular extending radially inward, to engage with a corresponding external thread of the component, wherein the first and second nut parts are configured to be freely rotatable relative to each other around the axial axis.
