Pull-Out Faucet Fixing Structure With Segmented Passages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pull-out faucet fixing structures are difficult to install and maintain, especially in narrow spaces, due to interference between pipes and hoses, leading to unsmooth operation of the pull-out spray head.
Innovation Solution
A fixing structure for a pull-out faucet featuring a housing with a mixing valve and a pipe line set, including static and dynamic pipes, and a positioning device with a seat and clamping set that allows for precise positioning and easy installation, ensuring the dynamic pipe moves smoothly without interference from static pipes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pull-out faucet is installed using a conventional fixing structure with multiple pipes and hoses passing through the seat, then the faucet can be fixed on the platform, but the pipes and hoses are pressed and interfered by one another due to limited fixing hole size, causing the spray hose to be pressed or wound when the pull-out spray head is pulled outward
Solution Approach 1:
The passage set is segmented into multiple independent passages: a first passage for cold water supply, a second passage for hot water supply, and a third passage for the spray hose. This segmentation separates the flow paths of different components, preventing interference between pipes and hoses while maintaining reliable operation of the pull-out spray head.
2Ease of manufacture
If the single handle pull-out faucet is installed from under the water platform, then the faucet can be fixed, but the installation is difficult due to the narrow space under the water platform
Solution Approach 1:
The installation approach is inverted from the conventional method of installing from under the platform to installing from above the platform. The seat is installed from the top surface of the platform through the fixing hole, allowing the installer to access all components and perform assembly in a spacious, accessible area rather than working from the confined space underneath.
3Adaptability or versatility
If the first passage, second passage, and third passage are arranged in the seat, then the pipe line set can be organized, but the limited size of the fixing hole causes the pipes and hoses to be pressed and interfered by one another
Solution Approach 1:
The passages are arranged in different spatial dimensions and orientations within the seat structure. The first and second passages are positioned separately for cold and hot water supply, while the third passage is specifically configured to accommodate the spray hose's movement. This three-dimensional arrangement optimizes space utilization while ensuring the spray hose can move smoothly without interference from other pipes.

AI summary
A fixing structure of a pull-out faucet is mounted on a platform with a fixing hole and contains a pull-out faucet including a housing, a pull-out spray head, a mixing valve, and a pipe line set; the pipe line set including a plurality of fixedly static pipe lines and a movably dynamic pipe line; a positioning device including a seat and a clamping set; the seat being fixed under the platform by the clamping set and being fixed in the fixing hole to fit with the housing, the seat including a passage set for inserting the pipe line set; wherein the passage set has a first passage for inserting the static pipe lines and a second passage for inserting the dynamic pipe line, and the first passage is spaced apart from the second passage so that the dynamic pipe line is limited in the second passage to move smoothly.
