Double-Handle Faucet Mounting Assembly for One-Step Countertop Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing double-handle basin faucets require tedious and complicated installation processes due to the need for securing three nuts under the countertop, and existing simplified methods still require under-counter nuts for two valve assemblies, preventing a complete one-step installation.
Innovation Solution
A double-handle faucet design featuring a mounting panel with integrated valve assemblies and a locking assembly that allows for installation from above the countertop, eliminating the need for under-counter nuts and simplifying the installation process by forming an integrated structure that can be secured to the countertop with a locking mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional under-counter nut structure is used to secure the faucet, then the faucet can be firmly installed, but the installation process becomes tedious and complicated requiring three separate nuts to be secured under the countertop
Solution Approach 1:
The patent merges the mounting base and valve assemblies into a single integrated countertop installation assembly. The mounting base incorporates two valve body cavities that receive the valve assemblies, eliminating the need for separate under-counter nut structures for each component. This unified structure allows all connections to be secured from above the countertop through a single locking assembly, reducing installation complexity while maintaining firm installation reliability
2Ease of manufacture
If separate under-counter nuts are used for each valve assembly, then each component can be independently secured, but the installation requires working entirely under the countertop making the process tedious
Solution Approach 1:
The patent inverts the traditional installation approach by designing the mounting structure to be secured from above the countertop rather than from below. The locking assembly engages with the mounting base from the top side, allowing installers to perform all assembly operations from the accessible above-countertop side. This inversion eliminates the need to work under the countertop while maintaining component independence through the modular valve body cavity design
3Ease of operation
If existing simplified mounting methods are used with a single screw rod, then faucet installation can be performed from above the countertop, but the two valve assemblies still require under-counter nuts preventing complete one-step installation
Solution Approach 1:
The mounting base serves multiple functions: it provides structural support for the faucet, incorporates valve body cavities for mounting the two valve assemblies, and integrates a locking mechanism for securing the entire assembly from above the countertop. This multi-functional design eliminates the need for separate under-counter nut structures, enabling complete one-step installation from the accessible above-countertop side while maintaining all necessary mounting and securing functions

AI summary
A double-handle faucet includes a water outlet member, a countertop installation assembly, and two valve assemblies. A mounting base and two valve body cavities are fixedly disposed on a panel body. A mounting panel and a locking assembly are respectively disposed on an upper side and a lower side of a countertop. The two valve assemblies are respectively connected to the two valve body cavities. The water outlet member is detachably connected to the mounting base. A valve body water channel is formed within the mounting panel connected to each of the two valve body cavities. A water outlet pipe is connected to a lower side of the mounting panel and is in communication with the valve body water channel. The water outlet pipe extends through the mounting base, and the water outlet pipe is fluidly connected to the water outlet member.
