Faucet Fixing Structure with Positioning Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional faucet fixing structures, particularly for single-handle pull-out faucets, fail to securely retain the faucet on the sink countertop, leading to loose installation over time and difficulty in installation due to lack of limiting structures preventing rotation of clamping screws.
Innovation Solution
A fixing structure comprising a faucet with a positioning device featuring a base with a peripheral fence, stop posts, and clamping blocks, where screw rods extend through orifices to rotate and engage stop posts, limiting clamping block rotation, ensuring secure retention of the faucet on the sink countertop.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fixing structures are used, then the faucet can be installed on the sink countertop, but the faucet becomes loose over time due to lack of limiting structures
Solution Approach 1:
The positioning device with limiting structure is installed beforehand to prevent rotation of clamping screws before tightening occurs. This preliminary positioning action ensures that the faucet remains securely fixed throughout the tightening process and during subsequent use, preventing the loosening problem that occurs with conventional fixing structures.
2Ease of manufacture
If conventional fixing structures without limiting structures are used, then the installation process is simpler, but the clamping screws rotate easily without retaining the countertop securely
Solution Approach 1:
The positioning device acts as an intermediary component between the clamping screws and the sink countertop. It provides a limiting structure that prevents unwanted rotation of the clamping screws while still allowing the installation process to proceed. This mediator ensures proper retention of the countertop without significantly complicating the installation procedure.
3Manufacturing precision
If a positioning device with limiting structure is added, then the faucet fixing becomes secure and precise, but the device complexity increases
Solution Approach 1:
The positioning device is segmented into distinct functional components: a base portion that contacts the sink countertop, limiting structures that prevent screw rotation, and positioning features that ensure accurate alignment. This segmentation allows each component to perform its specific function efficiently while keeping the overall design relatively simple and manageable.

AI summary
A fixing structure of a faucet is fixed on a sink countertop with a hole and contains a faucet having a housing, a pull-out spray head, a mixing valve, and a water supply set. The water supply set includes a cold-water inlet pipe, a hot-water inlet pipe, and a mixing outlet pipe. A positioning device includes a base having a peripheral fence, a bottom fence, and a mouth. The bottom fence has a limiting face and at least one orifice, the limiting face has a channel, two stop posts, and an abutting face. Two screw rods extend out of the hole and are rotated above the base. Two clamping blocks are screwed with the two screw rods and are limited by the two stop posts to rotate when the two screw rods are rotated, and the two clamping blocks move upwardly to retain a bottom end of the sink countertop.
