Rotating Faucet Outlet Pipe Joint for Precise Sealed Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional faucet designs require complex assembly processes, multiple components, and lack precise positioning, leading to increased costs, assembly inefficiencies, and potential water leakage due to loose connections under water pressure.
Innovation Solution
A connector assembly for a valve seat and outlet pipe featuring a first axial connection portion on the valve seat and a second axial connection portion on the outlet pipe, allowing for rotation-based mounting and positioning with guiding flanges for smooth assembly and secure sealing, eliminating the need for additional components and reducing mold-making costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the valve seat and outlet pipe are assembled using separate joint components, then the assembly can be completed, but the number of components increases and assembly cost rises
Solution Approach 1:
The patent merges the joint components with either the valve seat or outlet pipe into an integrated structure. The valve seat includes an integrated joint that directly connects to the outlet pipe, eliminating separate joint components. This reduces the total number of parts and simplifies the assembly process while maintaining connection functionality.
2Manufacturing precision
If no positioning design is provided on the bend circumference, then the structure is simpler, but position accuracy of the bend cannot be ensured
Solution Approach 1:
The patent introduces asymmetric positioning structures on the bend circumference, including positioning protrusions and corresponding positioning recesses. These asymmetric features provide precise angular positioning of the bend relative to the valve seat, ensuring correct orientation while maintaining a relatively simple overall structure.
3Reliability
If the outlet pipe is fixed with a simple positioning portion and recess design, then the structure is simpler, but the assembly may loosen or become wobbly under water pressure
Solution Approach 1:
The patent divides the positioning function into multiple segmented features: positioning protrusions for angular positioning, limiting protrusions for axial positioning, and sealing structures. This segmentation of positioning functions ensures stable assembly under water pressure while keeping each individual feature relatively simple.
4Productivity
If multiple separate components are used for valve seat and outlet pipe assembly, then each component can be manufactured separately, but the assembly process becomes more complex and time-consuming
Solution Approach 1:
The patent combines the joint functionality into an integrated structure with the valve seat or outlet pipe, reducing the number of assembly steps. The integrated joint allows for direct connection without requiring separate joint components to be assembled, thereby improving assembly efficiency and reducing process complexity.

AI summary
A connector assembly for connecting a valve seat with an outlet pipe and a faucet having the same are provided. The valve seat includes an outlet channel provided with an insertion hole and a first axial connection portion arranged at an outer cylindrical wall thereof. The first axial connection portion is located below the insertion hole. The outlet pipe includes an inlet end provided with a mounting portion and a second axial connection portion arranged at an outer surface of the outlet pipe and located close to the mounting portion. The second axial connection portion is detachably mounted into the first axial connection portion from bottom up to form a rotation point. By the outlet pipe rotated around the rotation point, the mounting portion is forced to be mounted and positioned inside the insertion hole of the valve seat firmly with sealing effect.
