Thumb Nut Mounting for Faucet Valves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The mounting and detachment of faucets for water outlet devices are inconvenient and labor-intensive, requiring tools like wrenches and screwdrivers, especially for three-hole faucets, which reduces working efficiency.
Innovation Solution
A method and device using thumb nuts with an annular plate, columnar nut main body, and hexagonal bottom sleeve to simplify the mounting process by manually passing valve and spout threaded bodies through the countertop, sleeving thumb nuts onto them, and tightening for secure fixation, eliminating the need for multiple tools and accessories.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional mounting methods using gaskets and locking screw nuts are employed, then the water outlet device can be securely fixed on the countertop, but tools such as wrenches and screwdrivers are required, increasing labor intensity and reducing mounting efficiency
Solution Approach 1:
The patent extracts the mounting function from the traditional multi-component system (gasket + locking nut + round head screw) and concentrates it into a single integrated thumb nut that combines sealing and fastening functions, eliminating the need for additional tools during mounting
Solution Approach 2:
The thumb nut merges the sealing function (previously performed by gasket) and the fastening function (previously performed by locking nut) into a single component, allowing both functions to be achieved through one manual tightening action without requiring multiple tools
2Reliability
If multiple components (gasket, locking nut, round head screw) are used for mounting, then the water outlet device can be securely fixed, but the mounting process becomes complex and time-consuming
Solution Approach 1:
The patent combines multiple mounting components (gasket, locking nut, round head screw) into a single integrated thumb nut component that performs both sealing and fastening functions, significantly simplifying the mounting process while maintaining secure fixation
Solution Approach 2:
The thumb nut is designed as a multi-functional component that simultaneously provides sealing (replacing gasket) and fastening (replacing locking nut and round head screw), allowing a single component to perform multiple mounting functions that previously required several separate parts

AI summary
A method of mounting a water outlet device, including passing a valve threaded body of at least one regulating valve and pipes from a top portion of a sanitary appliance countertop to a lower portion of the sanitary appliance countertop, where the valve threaded body of the at least one regulating valve is disposed at a lower end of the at least one regulating valve and is disposed out of a valve body of the at least one regulating valve and the pipes extend downward, sleeving a first thumb nut onto the pipes and the valve threaded body of the at least one regulating valve from bottom to top at the lower portion of the sanitary appliance countertop, and manually tightening the first thumb nut to fix the at least one regulating valve on the sanitary appliance countertop.
